Product Design

Every product must comply with a number of functional requirements or it isn’t a product, it is simply a useless object, trash or in some cases an artwork. It should be noted that art is not being compared to the former. Therefore the first phase of any design project requires a designer to focus his or her attention on the product application and gain a comprehensive understanding of its purpose and all the parameters associated with its intended use as well as its potential unintended use. The latter is as important as the former since unintended use can result in premature failure or serious safety risks. These criteria are often documented in specifications which define the product based on numerous parameters. This editorial will define the importance of such a document and describe how it establishes all the subsequent decisions made throughout the design development process.
There are no rules for standards for creating product specifications. Some products require extensively detailed documents which could hundreds or thousands of pages of specifications while others may be as brief as a page or two of specifications describing a part. It doesn’t matter how “simple” a product is, some form of documentation is always required to establish how that part or product is to perform based on one or more sets of conditions. Although this may appear to be sensible and obvious within the context of this editorial, product specifications are often overlooked and omitted from the design process. Omission typically results in confusion during development, costly rework, or catastrophic product failures. The specifications can be compared to a contract between the development team and the company for which the product is being designed as well as the end user. Specifications will not only influence the product design but also user manuals, regulatory compliance requirements and legal ramifications. Specifications should be written with careful consideration of proven engineering principles, user requirements, cost considerations, manufacturing parameters and marketing requirements. Incorrect assumptions will lead to costly recalls or unnecessary complications throughout the design process.
Since every product requires its unique set of specifications, this article cannot provide a recipe for creating a universal specification. However, an abbreviated list of general specifications can provided which pertain to all products. This list is provided below:

• Marketing

o User requirements
o Appearance
o Forecast sales

• Engineering

o Structural
o Mechanical
o Functional
o Life cycle/reliability
o Performance
o Testing and verification

• Financial

o Return on investment\amortization
o Capital availability
o Risk
o Vendor selection

• Manufacturing

o Location for production
o Supply chain
o Design for manufacture
o Number of parts
o Tooling design

• Regulatory compliance

o Recycling
o Compliance with specific regulatory body; UL, CSA, FDA, ROHAS, etc.

• Project Management

o Lead times
o Project risks
o Project schedule
o Available resources

A small subset of this list can be discussed in limited detail to serve as an example describing how tightly these parameters interrelated. Material selection for example is dictated by designers and is critical to overall product performance, cost, reliability, appearance, manufacturability, compliance with regulatory bodies, and in some cases lead times. Designers must have a thorough understanding of static and dynamic structural requirements for a product during short term as well as long term performance. Quantifying tensile strength, tensile modulus, fatigue resistance, creep and impact strength based on structural analysis will provide designers with physical property filters to select one or more viable plastic resins for a particular application. The list may be further truncated based on thermal conditions, chemical resistance, UV resistance, clarity requirements etc. Other factors including availability, cost, and lead times for delivery may further reduce the selection. Chosen materials may also be reviewed by the molding department or molder based on ease of processing, tool design and proposed secondary operations.
Structural analyses, testing and all the associated performance evaluations which effect material selection are based on the specifications. If product specifications omit potential exposure to harsh chemicals, or thermal conditions, the analysis and resin selection will be based on erroneous premises resulting in premature failure. Omissions in specifications typically arise from ignorance of the effects certain environmental conditions have on plastics. It is therefore crucial to test molded parts under expected environmental conditions as stated in the specifications to uncover potential failure. Rapid time to market often force designers to omit long term testing or simply ignore it all together which introduce high risks in a project. In such cases it is often advisable to include a plastics materials specialist to review the specifications and assess the potential risks. Material selection will influence wall thickness, design features such as ribs, bosses, snaps etc, and appearance for the designer. It will also effect a molder’s choice of tooling material, gate location and shrinkage rate and many other factors influencing tool cost.


Integrated Design Systems: Small, but Mighty

Flexibility and a willingness to adapt to changing circumstances will enable smaller industrial design firms to succeed when the economy is sluggish.

“Small industrial design firms, by nature, are more adaptable to changing circumstances and in today’s tough economy, this becomes an even more important asset,” says Michael Paloian, President, Integrated Design, based in Great Neck, N.Y.

As the owner of the small industrial design firm, Paloian is personally involved in all projects at Integrated Design. “There is an ownership mentality by our staff, which means that we take pride in and assume personal responsibility for each project,” he explains. “The client gets personalized attention, which may not be the case in larger firms.”


Color and Graphic Design

When engineers and rotational molders refer to design they are typically thinking about how the part will be molded or how it will perform after it is manufactured. Their concerns are typically focused on part geometry, material properties and other technical parameters.


What Constitutes Successful Industrial Design?

Industrial designers know that developing a successful product means more than simply solving an engineering problem or specifying what materials to use. Imparting a character and personality to a product, one that reflects the values of the manufacturing company, is as important to the product’s success as the actual functioning of the product itself. Strategically imparting these attributes in the design requires true artistic talents in addition to exceptional technical skills.


Designing an MRI Enclosure with Composites


Medical products have always included numerous design challenges because of their complexity, functional specifications, cost constraints, aesthetic requirements and size. These issues have forced designers to constantly search for cost effective, commercially proven manufacturing methods and materials that could transform their ideas into marketable products. A few years ago our design firm was awarded a project that represented a classic case study involving all the challenges previously cited. Integrated Design Systems was chosen by Fonar to develop a set of covers for their new Stand Up MRI system. This project was a unique and exciting opportunity for many reasons. First, we had an opportunity to meet and work with the current president of Fonar and inventor of MRI, Dr. Raymond Damadian. Second this was one of the physically largest and most challenging projects we ever encountered. Third, this product was the first of its kind, allowing patients to stand within an open framed MRI during scans. Since this product represented a revolutionary step forward in MRI, Dr. Damadian sought a design that was consistent with this breakthrough concept. He described his vision for the new product to convey comfort, technological leadership, quality and most of all openness. These characteristics had to be consistent with the massive inner structure of the MRI system. This massive steel structure was required to create the powerful magnetic which this technology was based on.

The project was initiated with a few meetings to gain a thorough understanding of the entire system and general principles of MRI technology. This information was compiled into a report which included the abbreviated list of design parameters stated below:

• The covers must be visually attractive and aesthetically compatible with medical office décor.
• A major objective is to create the illusion of space for the purposes of minimizing or eliminating claustrophobia for patients.
• The covers should easily be applied to the existing MRI structure which measured 9ft high x 10 feet wide and 14 feet long.
• Covers should be easily removed for service.
• Covers must be designed in a non-metallic material.
• The manufacturing technology for fabricating covers should be suitable for low production quantities with minimal tooling investment
• The final documentation package should be adequate for constructing all molds and covers.
• Seams should be minimized for sanitation purposes and visually consistent.
• Mounting hardware must be concealed and non metallic.
• Covers will mount to the existing frame, which cannot be altered.
• Covers should provide adequate clearance for internal components and wiring.

In addition to the above mentioned specifications, we had the added responsibility of identifying vendors, providing Fonar with vendor interface and assisting Fonar with pre-production project management during assembly of first articles. The design also had to account for wire routing and management between the MRI and installation site. After the product specifications were clearly defined, we imported Fonar’s CAD file of the inner structure into our CAD system .


Concept sketches were created using a printout of this structure as an underlay for maintaining proper proportions. Dozens of concepts were sketched, exploring a diverse cross section of possible enclosure designs .

During this phase of design, creatively and artistic intuition were emphasized to develop imaginative concepts which would capture the desired vision. Our objectives were focused on creating a design that would provide Fonar with a distinctive product image that could easily be transferred from one product to another. Parallel with this activity, an examination of competitive products was conducted to provide us with points of reference during our concept evaluations. Human factors issues were also reviewed to the designs would accommodate all patient orientations. These preliminary sketches were critiqued with Fonar based on initial visual impact, potential manufacturing options and estimated cost.

A few of the most promising concept sketches were selected for further refinement using CAD. Overall form, surface details and proportions of the outer covers were carefully sculpted around the underlying steel structure to insure that the final design could be implemented. These CAD models were completed for four concepts and ultimately rendered as photo-real images suggesting surface finish, color and shadow.





Each concept was presented to Fonar in large high-resolution color prints as well as electronic TIFF files. During this meeting each concept was reviewed based on overall visual impact as well as projected sales, tooling budget, amortization and number of parts. Servicing requirements were discussed based on ease of access during field service. Assembly steps were briefly reviewed based on estimated number of parts and proposed attachment methods. After this presentation was completed, Dr. Damadian selected the concept shown in the photo below.


This selection was made despite our recommendations that it was the most expensive design for tooling and overall part cost. We now faced our next greatest challenge of converting this concept into a real product based on a long list of very challenging design criteria. We entered this next phase of development with open minds to objectively identify materials and processes that would cost effectively reproduce this exciting design without sacrificing aesthetic details. Our first step in this process was to carefully examine the overall design and methodize where covers should be segmented based on molding, assembly, service and tolerances. After many hours of brain storming and reviewing proposed options we decided to split the covers into the pieces shown in the photo below. These separation boundaries satisfied most of our concerns.


Since the side panels were flat and could be specified in a non-ferrous material, we decided to choose fabricated aluminum sheet metal as our material and process. A series of flat reinforced 3.5 ft wide x 9 ft high x 1 in .125 thick reinforced aluminum sheet metal modules were designed to repeat along each side of the scanner (Photo 7). This saved on tooling investment and provided an accurate structural cost effective part. Sections of the machine that required easy access during field service were specifically identified by our client’s service department. These areas were optimized for ease of access by designing covers that could readily be removed by a field technician within a few minutes. Since the scanner frame was symmetrical left and right as well as front to back, covers were designed with symmetry to minimize tooling cost (Photo 8).The overall design was now mapped out for further detailing based on a specific process and material.


The major parameters affecting our decision for selecting an ideal material and process for the remainder of these covers is listed below:

1. Tooling cost had to be minimized and fall within a specific budgetary limit
2. The molding process had to consistently reproduce very large parts with complex surfaces and tight tolerances.
3. The molding process had to yield parts with excellent surface finish
4. Plastic parts were required to be structural and rigid so they could be easily transported and installed without fixtures.

Plastic molding processes that were considered are listed below with comments:

Reaction Injection Molding- Although this process is ideal for molding high quality, tightly toleranced, large complex parts, tooling costs would have been prohibitive. The investment required for machined aluminum tooling for these very large parts would have easily exceeded one million dollars. In addition, RIM polyurethane parts would have lacked the rigidity and structural integrity required during handling and installation.

Pressure forming &Twin Sheet Forming – Both of these processes were seriously evaluated for some of the shallow parts because of processing limitations. These processes are a variation of vacuum forming, which is based on the deformation of a heated sheet of plastic within a mold. Therefore part depth is limited because of material stretching and thickness variation during processing. Although tooling prices and parts costs were attractive, the process was disqualified because of material and processing limitations. Thermoplastic materials would have been too flexible for these large parts and most parts would have required too deep a draw for these processes.

Rotational Molding- Rotational molding is ideally suited for large complex shapes. Tooling costs are generally low and part quality can be consistently maintained during production. Parts are typically molded in cast aluminum molds with a hollow core. Unfortunately this process has two significant drawbacks, limited resin selection and poor tolerance control. The majority of resin molded is polyethylene, which is a low modulus material with a waxy surface finish. Limited tolerance control is partially due to the resin, however poor process control and tool quality are also contributors this drawback.

Chopped Sprayed Fiberglass – Chopped fiberglass or open mold hand layed fiberglass was also evaluated but discarded during this investigation. Although the process satisfied most of our requirements, it was rejected because of concerns for consistent quality and tight tolerance control. Lack of dimensional control caused by inconsistencies in this manually intensive process was confirmed after interviewing a number of processors. Processors were generally apprehensive of tight tolerances, wall thickness consistency, internal surface finish and overall geometry.

Resin transfer molding– Our familiarity with resin transfer molding was limited to a very general overview of the process. After speaking to representatives within the American Composites Manufacturers Association (ACMA), we were directed to a number of qualified experts in RTM, one of whom was John Moore of RTM Composites. During my telephone conversations with John, I became very impressed with his honesty and thorough knowledge of resin transfer molding. After evaluating my requirements he suggested that I consider a variation of RTM referred to as RTM light. His description of this process and its success in products like the Viper, aroused my interest. Although there were a number of questions regarding this process, our major concern was its lack of popularity within the composites industry and the limited number of experienced molders.

After evaluating the attributes and limitations of each process, we decided to focus our attention on conventional RTM and RTM light. Candidate vendors were identified based on recommendations obtained from the Composites Institute and suppliers within the industry. This pool of vendors was further analyzed by interviewing key personnel by telephone, receiving samples and examining facility photographs. The remaining three candidates were individually evaluated with personal interviews at their facilities and as well as ours. Visits to a few facilities helped us evaluate the small group of candidates based on their equipment, capabilities and products molded. One candidate had extensive experience in conventional RTM, another had extensive experience in RTM and RTM light. The third had mixed experience in RTM and polyurethane RIM molding.

Throughout this evaluation phase, the design was being refined and detailed with features that gradually included attachment methods, seams between covers and molding issues. After we decided to select RTM as the optimum molding process, panel details evolved with specific features for that process. During our evaluation, we asked questions and expressed concerns about specific design details with the candidates to test their knowledge of the process. Some molders could not commit to specific tolerances and proposed vague suggestions for addressing this issue. Other molders proposed splitting the front corner cover into two or more pieces which would later be assembled with bonding. Machining all the molds in aluminum was also proposed by some molders who were doubtful of the RTM light technology. Many of these alternative ideas introduced more problems than solutions and had to be discarded.

Our evaluation eventually narrowed the selection to one candidate for the project, Phoenix Industries of Crookston Ltd. Crookston, Minnesota, headed by Jeff Burgess at that time. Mr. Burgess is now with Acrylon Composites in Grand Forks, ND. Jeff’s extensive experience in RTM and RTM light was demonstrated by the size, complexity and number of different products that were manufactured in his plant with these processes. The other candidate specialized in molding conventional RTM parts which were heavily glass filled, non appearance products with demanding structural requirements. These applications required expensive machined aluminum molds and large clamping presses which would have been cost prohibitive for this application. The third candidate lacked the technical depth and focus on the RTM process since he was involved in three different molding processes within the same small facility.

Once Phoenix was selected as the molder, we worked closely with their tooling and processing engineers by emailing CAD files as the design evolved. When the design was approximately 80% completed, a project meeting was held at Fonar with representatives from Fonar, Phoenix, Integrated Design Systems (, and Ketco ( Ketco was a major contributor to this project based on their unique capabilities of CNC machining extremely large patterns and models directly from CAD files within very tight tolerances.

During this critical meeting every design detail was honestly and objectively presented by IDS for input from the group. Issues that were discussed are summarized below:

• The overall design was reviewed based on aesthetics and assembly methodology
• We examined molding issues pertaining to specific covers and how the mold would be parted.
• We discussed draft angles and depth of draw
• Surface finish was also reviewed based on molded in color with a gel coat or post operations such as painted polyurethane
• Ketco described their machining capabilities and how they could machine and deliver an interim non-functional model for an up coming trade show within 4 weeks
• Methods for attaching mounting blocks to the inside of molded covers were also reviewed.
• The overall schedule was discussed based on risks, backup plans and critical milestones.
At the end of this very productive meeting, a clear set of common objectives were established for the remainder of the project.

We proceeded with the design details to include draft, clearances, inserts, shut-offs, and all other molding features required to produce RTM parts based on our accepted specifications. Our ultimate objective was to provide Fonar with a complete set of production part files based on the technical requirements of the RTM light molding process .



We planned to release these files to the molder and tool maker for cutting patterns directly from these unedited CAD files. Solutions to the design challenges we faced throughout this development required imagination, keen awareness of manufacturing tolerance limitations and extensive technical knowledge in mold design. We routinely corresponded with engineers at Fonar for their comments on proposed methods based on various design alternatives. Our objective was to attach panels without fixtures. This concept required a careful analysis of cumulative tolerances resulting from RTM parts, sheet metal and machined parts based on different design alternatives. Tolerance limits were verified with each vendor, including Phoenix to ensure that molded parts would fit together as anticipated. To our pleasant surprise, Phoenix assured us that they could hold +/- .06” over 9 feet. Although I had reservations about this very tight tolerance, Jeff Burgess assured me that he would guarantee the parts to comply with this specification. We proceeded to leave only .125” clearance between all covers .


It should be noted that the RTM light process has many inherent advantages for yielding cost effective, high quality parts with tight tolerances and consistent surface finish. The process which has been perfected by JHM Technologies ( ) is based on a pressure balanced system of molds and resin transfer equipment. Internal mold pressure is initially evaculated to 6 to 8 psi (approximately ½ atmospheres or 14.7 psi) and monitored by a transducer, located approximately at the center of the mold. As resin is injected into the mold, injection pressure is regulated by the feedback from the transducer’s measurements of internal mold pressure. The balanced system pressure system permits the use of low cost minimally reinforced molds that will not blow apart or distort. Precut glass mat is placed in the cavity half of the mold without obstructing the gasket. Molds are kept closed by a high vacuum around the perimeter of the mold, between two sealed gaskets. This principle is the key difference between conventional RTM and RTM light.

Undercuts within some of the parts were reviewed with Phoenix and Ketco to discuss tool and part design. The most difficult part was the front corner cover which required complex twisted surfaces to be swept in the direction of tool draw. Despite our best efforts to avoid undercuts this part required a few removable pieces in the mold to create the desired appearance and function .

Parallel with this development, we examined design options for registering and fastening covers to comply with service, assembly and tolerance requirements for this room sized 14ft x 10ft x 10ft instrument. After reviewing all the design specifications, we decided to reference all the covers to mounting points on the inner machined steel frame. The inner steel frame was comprised of a few monolithic precision machined blocks that could be modified for adding attachment hardware. Since all covers were symmetrical about the center axis of the imaging area, we decided to use this central point as our zero datum. A precision machined fiberglass reinforced structure was designed to mount to the steel frame at this point. This frame would accurately support covers around the imaging area. Once these covers were properly positioned on the frame, additional symmetrical covers could be registered and added to the substructure. This assembly scheme provided a means of assuring that all covers would be symmetrical about the center of the instrument without fixtures.
One of our goals was to attach all covers with concealed hardware to maintain the desired aesthetic details. This objective was achieved by establishing a priority for assembling covers in a specific order. Placement of one cover over the mounting flange of another allowed us to locate non-metallic fasteners behind the most recently attached panel.

RTM parts provide rigid net shape shells devoid of any mounting features on the inside. Molded parts must be subjected to a few secondary operations before they can become functional covers. One of these operations is trimming. Trimming simple two-dimensional planar edges is relatively simple and can be achieved with a simple fixture or two axis CNC routers. However, these large complex parts with +/- .06” tolerances required 5 axis CNC routing with trimming programs based on part CAD files. Trimmed edges were designed along non-visible edges to minimize rejects due to potential cosmetic irregularities. This design detail yielded parts with molded features on all visible surfaces and along all dimensionally critical edges.



Extruded aluminum mounting rails were bolted along the exterior walls of the internal steel structure. Specially designed mounting hardware was attached to these rails which supported the sheet metal panels.


Mounting blocks were added to the rear side of the covers permitting attachment of fastening hardware on precision machined flat reference surfaces. These mounting blocks required their surfaces to be matched to the complex inner surfaces of the covers. Since repeated CNC machining for each block would have become cost prohibitive, we suggested that blocks should be cast in a net shape using high density polyurethane foam. The molded contoured block would be matched to the inner wall of the cover for which it was intended and securely bonded with a structural adhesive. After the blocks have been bonded in position, mounting holes for hardware and locating pins would be CNC machined using the CAD data files.


The final design can be viewed in the following pictures which illustrate many of the details cited in this article.



In conclusion, we would like to thank all those who participated in this project. Exciting projects such as this can only be realized by a cooperative team of dedicated individuals who share a common vision and determination to make it happen. In addition to the people involved in this program, this design would have been impossible to manufacture without RTM light technology. This derivative of RTM provided the perfect balance of tooling cost with part quality, size, complexity and structural integrity, required for this product. Hopefully this article will stimulate more interest in this relatively new molding technique which has a definite place in the growing composites industry.


Future Trends ( written in 1996)

The year is 2020. Materials and manufacturing technologies came a long way in the last century, but in the past two decades, the advancements have truly liberated the industrial designer. In particular, there have been significant strides taken in tool making, processing equipment and high-performance resins. Let’s review the radical developments of the past 25 years and look at four examples of their application.

Pressure to decrease tooling lead times inspired companies to experiment with stereolithography technology in mold making. For processing equipment, more design controls and modularity improved quality thermoplastic cyclic polyester reactive resins revolutionized very large low-pressure composite molding. As military and aerospace markets dwindled, composite manufacturing methods found commercial markets. New materials and reinforcements translated into more cost-effective manufacturing processes. Composite metals, plastics and ceramics improved product design while combinations of lightweight carbon and boron fibers with plastics yielded materials with physical properties unmatched by any natural material.

Processes such as resin transfer molding and pultrusion eliminated much of the labor associated with composites. To improve overall performance, coaling materials ranging from sand to diamonds were combined with different substrate materials through innovative techniques such as vacuum deposition, microwave plasma deposition, sputtering, arc spray coating and ion implantation. The result improved hardness, scratch resistance, corrosion resistance, sound absorption, multiple colors, abrasion resistance and biochemical compatibility. The demand for high performance materials in semiconductors, insulators and high-temperature materials led to the refinement of ceramic materials and manufacturing processes.

Improvements in processing resulted in ceramics derived from silicon nitride and boron nitride, which were coextruded within a polyethylene copolymer compound. The resulting filaments were sintered into extremely strong materials used as reinforcements for metals and plastics. Other processing methods included gel casting and sintering, but the most exciting innovations came out of the discovery in 1986 that a metal oxide rather than pure metal could be used to achieve superconductivity at much higher temperatures than thought possible. This, and subsequent compounds based on yttrium barium cuprate, paved the way for smaller and more efficient motors and electronic devices. These new materials and processes also led to the refinement of free-form fabrication technology, which was commercially introduced in 1987 with the presentation of stereolithography.

The new century brought new techniques based on the use of different plastics, metal powders, ceramics and even composites to expand the size and selection of parts. Other methods included solid ground curing, selective laser sintering, laminated object manufacturing, design-controlled automated fabrication, solid creation system, solid object ultraviolet laser plotting, ballistic particle manufacturing, printed computer tomography, shape melting and three-dimensional printing.

Products quickly incorporated this new knowledge to the point where free-form fabrication was routinely used in everything from appliances to replacement human body parts. Although the laser is common to all variations, materials and techniques vary widely. No longer are industrial designers limited to one material or solid walled shapes. To illustrate the paradigm shift that has resulted as these innovations opened new doors, let’s look at four 21st-century products.


In 2015, KTX Associates introduced the lawn Tank, the first self-powered robot lawn mower. This design expressed innovative use of material and manufacturing breakthroughs. The design team cleverly interpreted the mower with features common to military tanks. This reference suggested durability and provided functional benefits. Low profile electric motors of superconductive ceramic coils contribute to the low-profile appearance and high operating efficiency. One motor drives the rotor while the two stepper motors govern the mower. Built-in sensors guide the device around the lawn. An exterior photosensitive coating converts sunlight to electric energy, and batteries based on lead-coated glass mats form a recyclable plastic module, which continually recharges. This honeycombed modular structure of carbon reinforced nylon 6/6 acts as a support bridge. Designers used Helisys-laminated object manufacturing methods to form these complex shapes. Composite graphite/polyester molding compounds result in a lightweight, rigid deck.


Instant success greeted the wall-hung home computer from Somex in 2018. Its Industrial design teams redefined the computer to integrate with electrical devices throughout the home. Operated by voice or touch, the unit uses infrared and spread spectrum technology to communicate with or replace peripherals such as televisions, stereos, telephones, timers and surveillance equipment. The lightweight thin curved form features a variety of coatings, each for a specific purpose. Polyaniline, for example, will convert passive surface interactive displays, controls and keypads. Application of photosensitive silicon to other surfaces converts light into electric power. Santex’s solid creation system formed the smart composite modules that can be plugged into the main body for added functionality. Microchips and circuitry are directly implanted into the main body of the computer. The unit’s high efficiency and solar-powered coatings let it run indefinitely on long life batteries.


Magna introduced the ultrasonic clothes washer in 2012, a major departure from the bulky washers of the previous 80 years. Its piezoelectric spheres wash clothes by shaking off all dirt, using less than two galIons of water and special detergents. The same ultrasonic energy dries clothes after pumping out dirty water. By eliminating a rotary wash basin, the design team could achieve a flatter, more compact shape. Composite materials give the compact washer rigidity, light weight and free forms not easily achieved with stamped steel. A thermoplastIc elastomenc gasket forms a watertight seal all around the front door, which features polyaniline LED coatings to let users program the washing conditions. A diamond-coated polycarbonate blow-molded door permits total access to the wash chamber while providing a watertight seal and high visibility.


Lightweight, portable and durable were some of the adjectives for a table saw introduced by SaWell in 2012. The Alpha power tool division creatively applied new materials and manufacturing processes to a lightweight portable table saw that redefined design for the power tool industry by replacing massive and bulky forms with efficient shapes. The saw’s highly efficient compact 5 hp motor, made possible by superconductive wires, shares a tiltable housing with the saw blade. A stepper motor drive system controls blade tilt from a front control panel that uses an electroluminescent display. Built-in rotary and linear capacitive sensors determine precise blade angle and fence distance. Boron nitride rods embedded in a clear, diamond-coated polycarbonate leaf provide a very rigId lightweight surface. Fold-down panels, created in three-dimensional printing technology pioneered by MIT in 1995, and double-shot injection molded foldout legs, molded in bright colors around a carbon-graphite core, provide rigidity, lightweight and strength. Visually bold and colorful rubber feet dampen vibration and add stability during use. The unit folds into a 4- thick case for easy transport.

This brief glimpse of major developments in materials and processes during the past 25 years offers insight into the creative designs introduced by industrial designers who took advantage of the technology.

What do we have to look forward to? Within the next 25 years, we may be genetically designing products, colonizing distant planets and living under the sea. Industrial designers can look forward to a time when products will have no specific top and bottom orientation. We will design for a three dimensional environment where ecosystems, materials, societies and life will be carefully managed in order to sustain themselves. New materials will be fabricated from solar energy living organisms may be designed to work in conjunction with inorganic objects as a routine part of our exciting designs. The only limit IS our imagination.
