- Abstract
In this study, a device that can automatically disinfect door handles and prevent contact infection was designed. This device will spray alcohol onto door handles –6 s after the user leaves, as detected by infrared sensing. We used observation and design thinking methods to carry out needs analysis, prototype design, experimental testing, and effect evaluation. The experimental results showed that this delayed spraying method can effectively reduce the amount of bacteria and dirt on door handles and also increase the user’s sense of hygiene and safety. Moreover, this method can contribute to epidemic prevention without spraying alcohol directly onto the human body.
