When a medical instrument company approached David Funnell, president of Funnell Instruments, Ltd. (Uxbridge, MA), about designing a less expensive method for manufacturing biopsy-sampling jaws, he knew what he needed to do. "One of the major weaknesses of the typical bowel-biopsy forceps is the narrowness of the hinge portion of the jaw," Funnell says. So Funnell broadened the hinge base. In minimally invasive abdominal surgeries, it is often necessary to grasp tissue—to pinch, but not to pinch too hard. Long-jawed instruments typically develop crosswise looseness at the tips that can potentially create a perforation hazard. To eliminate this problem, Funnell designed the Haploid™ Jaw, his stamped biopsy-sampling instrument, with an alternate-overlapping cutting pattern. He made the device from stamped corrosion resistant 300-series stainless steel. "Other instruments use 400-series material that frequently develops porosities," says Funnell. He knew from the outset that he would use metal forming to help lower the costs. "I've been fascinated by the materials-savings by the automotive industry by moving from a combination of forging and metal-removal to that of metal forming," he says. "I believe the Haploid Jaw will outperform all other designs on a dollars-per-specimen comparison." For more information, contact Funnell at (800) 809-9833.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
