Should You Design for Corner Cases

Abstract

Kirk and Fred discussing whether to design for the anticipated extreme corner case of environmental stresses that some percentage of the product may see in use.

Key Points

Join Kirk and Fred as they discuss design issues of determining the cost versus risk in future product use conditions and extremes in use.
Topics include:

• Reducing variation in common components, such as screw fasteners throughout a mechanical assembly, is a part of Design for Manufacturing best practices even though the screw may be more than needed in some parts of the design.
• Corner cases of stress conditions are hard to estimate in advance, and most design engineers are probably not estimating use conditions that is close to considered abuse although the customer may not consider it abuse.
• The typical consumer smartphone and computer product specifications has been 0 degrees C to +35 degrees C which is lower that human body temperature, and is ignored by most consumers since we carry smartphones in our pocket and use them when the weather is warmer than 35 C.

Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques, to field data analysis approaches.
