Creating products that are functional relies on design. Creating products that people need relies on ideas and forethought. Having a good design without a need for it brings Rube Goldberg to mind. Having a great idea with no design brings unicorns to mind. You have to incorporate good ideas with proper design in order to create a product that people can use.
Here at Williams Designs and Concepts we strive to keep this philosophy at the forefront of product development. Ralph Williams developed the smoke detector tester for high-velocity-air environments because he saw a real need for this tool. He worked on these high-velocity systems and was able to test his ideas in a real world scenario. See the product page for more info on this product.
