käyttöpituuksia
Käyttöpituus is a Finnish term that translates directly to "duration of use" and refers to the period over which a product or service is intended to be functional or viable. The concept is applied across various sectors, including consumer electronics, industrial machinery, and software licensing agreements. In product design, engineers estimate a nominal käyttöpituus to guide material selection, component tolerances, and maintenance schedules. This estimate often reflects both technical and economic considerations, balancing durability with cost.
In the automotive and aviation industries, käyntöaika is critical for safety and regulatory compliance. For example,
Consumer products such as household appliances often come with warranty periods that implicitly represent a käyttöpituus.
Designing for optimal käyttöpituus requires interdisciplinary collaboration. Materials scientists, reliability engineers, and business analysts assess failure
