Abstract：Addressing numerous safety issues inherent in current household ultraviolet disinfection devices,this paper utilizes the TRIZ innovation theory.Initially,it analyzes the problem of"traditional low-pressure mercury vapor lamps being ineffective for sterilization"in household ultraviolet disinfection devices.Subsequently,it employs functional analysis and causal chain analysis methods to identify key issues.Finally,it utilizes function-oriented search analysis and physical contradiction analysis methods to determine solutions.Based on the solutions,a UVC-LED disinfection device was designed.According to functional testing of the equipment,all indicators meet the design requirements.
