Industrial designers at Davantech are experienced in designing for maximum product features and specifications as well as for optimal manufacturing. At the beginning of every design project, our designers do extensive research into the basics—
- Who your target users are
- How your product will be used
- Where it will function in
- You want the design to communicate
Design and Ergonomics
The main aspects of marketability are design and ergonomics. Simply, design is about esthetics—if your product does not look appealing, it will not sell. The value of a good industrial design is obvious: an attractive design not only helps to sell more products, but it also allows you to charge higher prices, which means that the actual profit per unit can be a multiple of the profit on a so-so looking product.
Ergonomics, on the other hand, focuses on the human interaction with a product: How does it feel in your hand? Do the shape and contours conform to the part of the body that comes into contact with the device?
Design for Manufacturing
While design and ergonomics are instrumental to making a product marketable, they alone do not guarantee success. Careful consideration of production in the initial stage is crucial in product design as a sizeable percentage of the product’s lifecycle cost is committed at this time (cost of materials, production of parts, and assembly).
Davantech’s designers integrate design and industrialization into a single process, with the goal of designing a product that is easily and economically manufactured. This is achieved by early collaboration with mechanical and electronic engineers and production specialists to produce a design that fulfills price and manufacturing parameters, i.e., the relative ease to manufacture a product, part or assembly—while ensuring that design intent is preserved.
Some basic guidelines our designers follow:
One of the best methods for reducing manufacturing costs is to reduce the number of parts in a product. Fewer parts often lead to less sourcing, development, purchasing, assembly, testing, development time and testing.
The use of modules in product design significantly reduces the level of intensity of manufacturing-related activities. In addition, it provides ease in repairing, maintaining, or replacing a part of the device in the event the part were to fail.
Standard components are naturally less expensive than custom-made ones. The availability of these components means reduced lead times—the amount of time it takes to procure components. Using standard parts also offers peace of mind with regard to the components’ reliability. We have a huge chain of suppliers for standard components.
Design with ease of fabrication in mind. To minimize manufacturing cost, we select the optimal combination between material and fabrication process. By and large, secondary operations such as painting, coating, and surface finishing should be avoided. Requiring a high degree of precision on parts should also be avoided whenever possible as this poses manufacturing challenges and increases the reject rate (yield loss), resulting in higher part production cost.
Use rounded corners as opposed to sharp angles since plastic flows better through rounded corners during plastic injection. Concurrently, (draft) angles—an angle incorporated into a wall of a mold so that the opening of the cavity is wider than its base—are needed so that a plastic part can be released from the mold without damage.
In addition, design minimizing assembly directions. Electronic products should be assembled from one direction— ideally from above. This way gravity works with you during the assembly process as opposed to slowing down assembly by having to compensate for its effect.
