Fundamentals of Safety Margins
podcast episode with speaker Fred Schenkelberg
One way to create a robust product or system is to consider all the stresses and design to withstand those stresses. We often do not know all the stresses, magnitudes, and ranges of variation. We know that many materials degrade with time, yet we do not know precisely how much or how fast. We also do not know what new stresses may arise or how stresses will change over time.
With so many unknowns, we turn to safety margins to address the unknowns. The process is simple enough, meaning we will design a product to withstand more stress than we expect. For example, if designing a bracket that is expected to carry a 100-pound load, we design a bracket capable of withstanding a 200-pound load. That doubling of capability is a 2x safety margin.
Let's examine safety margins and why they are one method to design robust products that also improve product reliability performance.
