Size, geometry and cost constraints posed problems for design engineers at Gyrus Medical in Minneapolis MN, when designing the jaws for a single-use bipolar open-forceps surgical instrument that uses RF energy. Tight tolerances over the length of the part (about 4.5 inches) were also an issue. The instrument will only perform properly if the surfaces remain parallel. Gyrus looked at casting and machining before choosing metal-injection molding. "Any time we need that kind of accuracy, we're going to look for a MIM-molded part," says Craig Stowell, director of engineering for Gyrus Medical. Phillips Plastics developed custom ceramic fixtures to support the parts to eliminate sagging during the production process. The parts then went through a calibration process to meet final print specifications.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
