Product Design Optimization – Some Ideas of mine that are decades old , related to EDA and Product Design.
Make Practical (it works), Affordable, Usable (ergonomics), Safe, Reliable (robust), Durable and Consistent, Maintainable (means servicing) Products.
Dust and Contamination in Connectors
Once i opened a RF Millivolt Meter of Marconi Instruments. It did not have a spec of dust inside, not even one micron size of dust particle.
Connectors exposed to Environment should not only be Corrosion resistant but also Dust, Grime & Insect Proof! Dummy Covers on exposed units.
Air Vents, Fans & Unused Slots in Modular Instruments. Missing Fasteners in cabinets, gaps in panel components collect Dust & Insects inside
Dust + Moisture + Smoke + Pollutants = Conductive Grime Deposits on PCB, Parts & in-between the IC pins. Can Simulation include this aspect.
Virtual Environmental Testing a part of simulation and EDA, just like Mechanical Modelling and Studying Thermal Gradients on PCB.
