Rehkemper Invention and Design, which spends most of its time inventing new toys, has broadened its capabilities and designed a product for the health care market. Using SolidWorks CAD (www.solidworks.com) software, the toy firm created a dental-care system that combines a toothbrush, tongue brush, and irrigator. The AquaSonic Oral Care System requires no batteries or electricity because it works on air pressureó similar to Rehkemper's toy plane designs. Engineers used the software to design everything, right down to the bristles. "It was easier to see what we were designing with 3D models than with drawings or continuous mockups," says CEO Steve Rehkemper. He adds that the software cut time production by 50%.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
