Called the "Queen of Carts," a new, safer shopping cart has won the ninth annual National Engineering Design Challenge. JETS--the Junior Engineering Technical Society--sponsors the high school competition. JETS this year asked students nationwide to design and build a shopping cart that would not tip over and injure young children. Winning the finals held at George Washington University (Washington, DC) was a team from West Perry High School (Elliottsburg, PA). The team's invention, a six-wheel cart made of steel with nylon webbing around the sides, includes a nylon child seat in the front. The Queen of Carts' two center wheels serve as stabilizing wheels and the pivot point. Thus, the cart can turn from either front or back around the center pivot wheels. The new design turns 360 degrees in its own length, while the standard cart, with pivot point in the back and turning wheels in the front, takes twice the cart's length to circle.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Weaned on the relatively effortless connectivity of today’s massive variety of consumer electronic products, automation users in the IIoT will likely not tolerate too many competing, piecemeal standards for long. And the Industrial Internet Consortium is trying to preempt history.
