Definition
A design-simplification process within Speed Design Review (SDR) that reduces part count: eliminate, combine, alternative methods, change assembly sequence, simplify.
In detail
ECASY is a design-simplification method used within Speed Design Review (SDR) that reduces part count through five steps — eliminate, combine, substitute, change sequence, and simplify — thereby lowering cost and improving reliability. Outputs typically include a simplified design and a before/after part-count comparison.
Example in practice
An electronic product design had 50 parts. The engineer applied the ECASY method, first eliminating unnecessary decorative parts, merging brackets with similar functions, substituting standardized screws, and changing assembly sequence to reduce flipping, ultimately reducing parts to 30 and shortening assembly time by 30%.
