Top tips and tricks for feasibility testing

Custom test setups, multi axial loading, or unique wear paths often require complex fixtures and equipment. While there are test standards available (in some but not all cases), designing the test to evaluate a critical feature of your part needs to be considered.

Avoid unexpected failures and keep your project on time and on budget with these best practices.

You’ve passed through your design freeze, parts are rolling in and everyone is excited as verification testing starts.

The first few tests are underway and — uh-oh — your device’s performance is not meeting your requirements. Scrambling to root-cause analysis and rationalizing the poor results leads to no avail. The numbers don’t lie.

You tell the leadership a redesign is needed, timeline is extended, bu…

Finite element analysis can help design a robust mechanical architecture to pass one of the toughest tests in medical device design.

Giorgio Sardo, Flex

Time to market is a key factor for new medical product success. Designers now use modeling and simulation to pass one of the most severe tests: 60601-1, an international standard applicable to all medical electrical equipment and systems. By skipping costly trial-and-error iterations, they can quickly define the parameters for a robust mechanical architecture. Drop simulation can predict the test result and also support a failure analysis investigation.

If you’ve ever dropped your phone, your immediate concern is if it still works. Medical device users don’t experience the same anxiety if they drop their device because medical electrical equipment must meet a set of…
