longlifetime
Longlifetime is a term used to describe products or components engineered to deliver an extended operational life, prioritizing durability, reliability, and ease of maintenance. It encompasses the expected time to failure under typical use and is often evaluated through reliability metrics such as mean time between failures (MTBF), mean time to failure (MTTF), and the failure rate over time. Manufacturers may use accelerated life testing and field data to model longlifetime performance and to set design margins that reduce the likelihood of premature end-of-life.
In practice, longlifetime is applied across consumer electronics, industrial equipment, automotive parts, and energy systems, where
Design strategies include selecting durable materials, robust packaging, wide operating temperature ranges, redundancy, modular design for
Challenges include higher upfront costs, increased weight or size, potential environmental impacts of longer product life
Related concepts include reliability engineering, durability testing, product lifetime assessment, and sustainable design.
