Is it possible to verify and validate the safety and efficacy of medical devices if they could be connected to unknown current and future products? The medical device industry is working with the FDA to work out the safety issues of device interoperability.
As part of the V&V test procedure, we designed a gravimetric means to characterize the volumetric and flow-rate accuracy of a couple of precision injection instruments. With this setup, we’re able to achieve measurement resolution of just 0.1 milligram and reduced the error due to water evaporation to 40 times better than using a mineral oil emulsion.
I don’t learn anything new from examining a design for the 23rd time. I’ve checked for mistakes, but it’s all based on what I already know and a few educated guesses. The only way I can learn more is by building.
Making progress feels good, but when progress slows or I’ve hit a roadblock, it can be frustrating. When I need some fresh ideas, it’s time for a distraction.
Prototypes are essential to testing system performance. However, due to the current technological constraints of creating microscale prototypes, compromises in the characteristics of the prototype usually must be made, which can lead to unforeseen, expensive problems on the production line. Fortunately, basic, fundamental models of significant aspects of the system (first-principles modeling) can be “calibrated” through the use of focused CFD models and empirical data. The result is improved models that allow the designer to bridge the knowledge gap between paper and production.
Recently, I published an article in MicroManufacturing Magazine about the challenges of designing microparts for manufacture. Not unlike any collaborative process, good communication is the key to a successful project.
In tribute to our 10 year anniversary, I thought others outside of Key Tech might like to hear some of our more colorful screw ups. So I put together a four-part series of what I think are some of our best. I hope you find something of value.
