Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrogen peroxide is evaporated and fed into containers with air stream, then sterilization effect is achieved, but precise regulation of hydrogen peroxide quantity is difficult
Solution Approach 1:
The patent changes the physical state parameter of hydrogen peroxide from liquid to vapor phase through controlled evaporation. By regulating the evaporation process and temperature parameters, precise control of hydrogen peroxide vapor quantity is achieved, resolving the contradiction between achieving sterilization effect and precisely regulating the amount supplied.
2Productivity
If hydrogen peroxide mixture is rapidly vaporized in heat exchanger, then sterilization speed is improved, but residual mixture may permanently damage the heat exchanger
Solution Approach 1:
The patent applies preliminary action by pre-mixing hydrogen peroxide with air stream before it reaches the heat exchanger. This preliminary mixing ensures that the hydrogen peroxide is already dispersed in small concentrations, allowing rapid vaporization without creating damaging residual concentrations that could harm the heat exchanger, thus resolving the contradiction between sterilization speed and equipment durability.
3Stability of the object's composition
If carrier gas flows transversely to hydrogen peroxide injection direction, then mixing is improved, but exact regulation of hydrogen peroxide amount is difficult
Solution Approach 1:
The patent uses pneumatic principles by introducing carrier gas (air stream) that flows transversely to the hydrogen peroxide injection direction. This creates effective mixing through fluid dynamics while the system maintains regulation capability through controlled injection parameters, resolving the contradiction between mixture uniformity and precise amount regulation.
