Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrogen peroxide is evaporated using conventional evaporators with stabilizers, then sterilization effectiveness is maintained, but deposits form on the evaporator surface leading to non-uniform evaporation and performance impairment
Solution Approach 1:
The invention extracts and removes the stabilizer component from the hydrogen peroxide solution before evaporation, eliminating the source of deposits while maintaining the sterilization effectiveness of the hydrogen peroxide vapor
Solution Approach 2:
The invention performs preliminary filtration of the hydrogen peroxide solution to remove stabilizers and impurities before the evaporation process, preventing deposit formation on the evaporator surface and ensuring uniform evaporation throughout operation
2Stability of the object's composition
If stabilizers are added to hydrogen peroxide to prevent decomposition, then solution stability is improved, but residue formation occurs during evaporation requiring complex cleaning processes
Solution Approach 1:
The invention extracts and removes stabilizers from the hydrogen peroxide solution through filtration before evaporation, eliminating residue formation and simplifying the cleaning process to minimal maintenance requirements
Solution Approach 2:
The invention uses disposable or easily replaceable filtration elements that capture stabilizers, allowing simple replacement rather than complex cleaning of the evaporator system
3Reliability
If deposits form on the evaporator surface, then cleaning is necessary to maintain performance, but cleaning processes are time-consuming and complex
Solution Approach 1:
The invention performs preliminary filtration to remove deposit-forming stabilizers before evaporation, preventing deposit accumulation and eliminating the need for time-consuming cleaning operations
Solution Approach 2:
The continuous filtration system automatically removes stabilizers and prevents deposit formation during operation, making the system self-maintaining without requiring manual cleaning interventions
