Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vacuum sealing mechanism with multiple components is used, then sealing reliability is improved, but device complexity increases and maintenance cost increases
Solution Approach 1:
The patent combines multiple sealing functions into a single integrated sealing ring that includes both the first sealing portion for initial sealing and the second sealing portion for vacuum maintenance. This merging eliminates the need for separate vacuum packing members and coupling mechanisms, thereby reducing device complexity while maintaining sealing reliability.
Solution Approach 2:
The sealing ring is designed to perform multiple functions: initial sealing upon lid closure, vacuum sealing when vacuum pressure is applied, and automatic restoration to initial state when vacuum is released. This multi-functionality replaces what would traditionally require multiple separate components, reducing overall device complexity.
2Reliability
If a vacuum sealing mechanism with multiple components is used, then sealing reliability is improved, but replacement cost increases when parts are damaged
Solution Approach 1:
By merging the vacuum packing member, packing coupling means, and support structures into a single integrated sealing ring, the patent reduces the number of replaceable parts. When damage occurs, users only need to replace one component rather than multiple separate parts, significantly reducing replacement cost and simplifying repair procedures.
Solution Approach 2:
The sealing ring is designed as a separable component that can be independently removed and replaced from the container lid, while the rest of the container remains intact. This segmentation allows for economical replacement of only the sealing ring rather than the entire container assembly.
3Reliability
If a complex vacuum sealing mechanism is used, then sealing performance is improved, but ease of operation deteriorates
Solution Approach 1:
The sealing ring automatically transitions between sealing states based on vacuum pressure without requiring user intervention. When vacuum pressure is applied, the second sealing portion automatically engages; when vacuum is released, the elastic restoration automatically returns the sealing ring to its initial state. This self-service mechanism eliminates complex manual operations while maintaining high sealing performance.
Solution Approach 2:
The sealing ring incorporates elastic deformation capability, allowing it to dynamically adapt its shape in response to vacuum pressure changes. This dynamic behavior enables automatic sealing and unsealing operations without complex mechanical controls, improving ease of operation while maintaining sealing performance.
