Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical deodorants are used to suppress bromhidrosis, then odor removal effect is improved, but harmfulness to human body increases
Solution Approach 1:
The patent replaces chemical deodorants with a physical plasma-based sterilization system. The plasma generation unit creates reactive plasma species that sterilize bacteria causing body odor without requiring chemical substances, thereby eliminating the harmful effects of chemicals like aluminum salts and triclosan while maintaining effective odor control
Solution Approach 2:
The patent changes the operational parameters by using plasma discharge conditions (voltage, gas flow rate, discharge time) to control bacterial sterilization. By adjusting these physical parameters, the system achieves effective odor removal through controlled plasma treatment rather than chemical application
2Reliability
If plasma concentration is increased to enhance sterilization effect, then bacteria elimination is improved, but plasma activation stability becomes difficult to maintain
Solution Approach 1:
The patent implements continuous gas circulation through a gas circulation line that recycles unreacted gas back to the plasma generation unit. This continuous circulation maintains steady plasma activation levels and ensures consistent sterilization effect without requiring excessive plasma concentration
Solution Approach 2:
The gas circulation system acts as a feedback mechanism where the state of the gas after plasma treatment is continuously monitored and fed back to the plasma generation unit, allowing dynamic adjustment to maintain optimal plasma activation stability while achieving effective sterilization
3Quantity of substance
If gas circulation is implemented to maintain plasma activation, then plasma concentration is improved, but device complexity increases
Solution Approach 1:
The patent merges the gas circulation function with the existing device structure by integrating the gas circulation line within the housing. The circulation path utilizes the available internal space efficiently, combining multiple functions (gas supply, plasma generation, gas recirculation) into a compact integrated system rather than adding separate independent components
