Application of form generation in design for the improvement of users' perception of public faucet hygiene

Abstract

Abstract─ ─ ─ ─With the growing global population, there is an increasing rate of human contact. In particular, we often find that many public restroom users collect water with cupped hands to pour on the faucet switch after washing their hands due to their suspicions about the lack of hygiene. This study redefined the faucet form by using form generation, and improved the design by addressing the problem of faucet hygiene based on the user behavior-centered concept. After the Design for Assembly (DFA) was found by 10 expert designers, the samples were created to be used in a survey on users' hygienic fear and user satisfaction. The statistical analysis of the survey results shows that 75% of subjects were unafraid of the newly designed faucets and 100% of them gave significant and positive satisfactory responses for faucets based on user-centered design in terms of operation and aesthetics.When using the newly designed faucets, the subjects still washed them with water, but the amount of wasted water was significantly reduced through the design improvement.
