Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple removable layers are used to adapt to different cable diameters, then adaptability is improved, but device complexity increases
Solution Approach 1:
The sealing module is divided into multiple removable layers of decreasing diameter, allowing selective removal to adapt to different cable sizes. Each layer can be independently peeled off to expose the next smaller layer, providing a segmented approach to size adaptation that simplifies the overall design while maintaining versatility.
Solution Approach 2:
The layers are arranged in a nested configuration where each layer is positioned inside the previous layer, similar to nested dolls. This nested structure allows compact storage of multiple size adaptations within a single sealing module, reducing device complexity while maintaining high adaptability to various cable diameters.
2Ease of operation
If layers are made with controlled adhesion for easy peeling, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
Different adhesion properties are applied to different interfaces between layers. The adhesion strength is locally optimized at each layer interface to achieve controlled peeling behavior, where layers can be easily removed one by one while maintaining sufficient bonding during normal operation. This local quality approach balances ease of operation with manufacturing feasibility.
