Will reparable designs help reduce electronics waste?

Another one bites the dust!

Apparently, my lovely wife is one of the best at finding stress testing limits of kitchen blenders, or we are unlucky at getting blenders that had some latent defect.  She has discovered the destruct limit of 3 blenders within months of use. She does not do in the formal HALT methodology, as they break in what most would consider normal use conditions. It may have been a valid HALT evaluation if she had started with soft or easy to blend materials, starting with o ice or nuts and measured the time to reach its destruct limit. [Read more…]

Abstract

Kirk and Fred discussing comments we have received throughout the history of “Speaking of Reliability”. In this podcast we discuss one of the questions “should I calculate an average MTTR or MTBF ? “. We review the reasons that calculating an average time to or between failures does little to help make more reliable systems.  ᐅ Play Episode

Reliability engineers have traditionally been asked to answer a common question during development of a new device or system, and that is “How long will it last?”.

It is the eternal question in equipment reliability development, and it really comes down to “that depends on many factors”. One question that needs to be asked is how long do you need it to, or should it last? [Read more…]
