The washing machine at Edward Nauman's house kept overflowing
and flooding the floor, so he designed a flood sensor to cut the power to the
washing machine if the water in the drain rose within 1.5 inches from the top.
The level sensor is mounted in a hole drilled in the drain pipe and the
electronics are mounted in a box on the wall next to the power outlet. The box
plugs into the wall and the washer plugs into the box. When the water rises to
the sensor, a switch in the box cuts the power.
Shutting off the machine at the first sign of overflow is one way to stop the symptom, but clearing the drrain would be an actual fix. See "the case of the refilling washing machine." The big problem in this tale is poor drain function, which will only get worse.
Our LinkedIn systems and product design engineering group discusses if they are happy with their decision of remaining a technical contributor instead of becoming a manager.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
