Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connecting device is used to rotatably connect main bodies, then the device structure is simple and easy to manufacture, but folds and crumples occur on compressed surfaces leading to degradation
Solution Approach 1:
The patent applies composite materials by combining a ferromagnetic material layer with a non-magnetic material layer to form a coating mechanism. This composite structure prevents folds and crumples on compressed surfaces while maintaining rotational functionality, resolving the contradiction between reliability improvement and device complexity increase.
Solution Approach 2:
The patent replaces conventional mechanical connection methods with a magnetic connection system. The magnetic mechanism uses magnetic attraction forces between ferromagnetic components to achieve connection and rotation, eliminating the need for complex mechanical fasteners and reducing the risk of folds and crumples.
2Shape
If the connecting device structure is optimized for appearance, then aesthetic appearance is improved, but folds and crumples may still occur on compressed surfaces
Solution Approach 1:
The coating mechanism uses composite materials with a ferromagnetic layer and non-magnetic layer that work together to maintain surface integrity during compression and rotation. This allows the connecting device to achieve both aesthetic appearance and prevention of folds and crumples.
Solution Approach 2:
The patent changes the material parameters of the coating mechanism by using ferromagnetic materials with specific magnetic properties and non-magnetic materials with appropriate mechanical properties. This parameter optimization ensures surface integrity is maintained while achieving desired appearance quality.
