Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sterilization systems are used, then sterilization function is provided, but device complexity and risk of cross-contamination increase due to complex piping and steam injection systems
Solution Approach 1:
The patent extracts the steam generation function from external facilities and places a compact steam generator directly within the mobile sterilization cart. This eliminates the need for complex external piping and steam injection systems while maintaining sterilization effectiveness, directly resolving the contradiction between reliability and device complexity
Solution Approach 2:
The system generates its own steam internally through the integrated steam generator and uses this self-produced steam for sterilization through UV-C irradiation and thermal processing. This self-service approach eliminates dependence on external steam facilities and complex piping infrastructure, reducing system complexity while ensuring reliable sterilization
2Ease of operation
If mobile sterilization system is used, then transportation flexibility is improved, but thermal conditioning efficiency may worsen due to limited space for thermal management components
Solution Approach 1:
The patent combines multiple functions including steam generation, UV-C irradiation, and thermal conditioning into a single integrated control system within the mobile cart. This merging of functions maximizes the use of limited space and energy resources, maintaining thermal conditioning efficiency while preserving mobility
Solution Approach 2:
The system uses a controller to dynamically adjust thermal conditioning parameters based on the mass and type of waste being processed. This adaptive parameter control optimizes energy efficiency within the constrained mobile environment, resolving the contradiction between mobility and thermal conditioning efficiency
3Object-affected harmful factors
If sterilization is performed at generation site, then cross-contamination risk is reduced, but system mobility and adaptability to heterogeneous waste loads worsen due to specialized facility requirements
Solution Approach 1:
The mobile sterilization cart is designed as a universal system that can handle heterogeneous waste loads including BIHW, general waste, and contaminated surfaces. The integrated control system adapts processing parameters based on waste type, providing versatile on-site sterilization capability that reduces cross-contamination while maintaining adaptability
Solution Approach 2:
The system dynamically adjusts its sterilization process based on the specific waste load being processed. The controller modifies thermal conditioning parameters, steam generation rates, and UV-C exposure times according to the mass and characteristics of the waste, enabling effective handling of heterogeneous waste while maintaining mobility and on-site processing capability
