Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid face-fitting frame is used, then the structural stability is improved, but the comfort for users with different face shapes deteriorates
Solution Approach 1:
The face-fitting frame transitions from a static rigid structure to a dynamic flexible structure that can adapt its shape. The frame is designed with flexible materials and hinge connections that allow it to deform and conform to different facial geometries while maintaining structural integrity through controlled elasticity.
Solution Approach 2:
The physical parameters of the face-fitting frame, particularly its flexibility and deformability, are changed to enable adaptation. The frame material and structural parameters are selected to allow elastic deformation within a specific range, enabling the same frame to fit various face shapes while maintaining sufficient structural stability.
2Adaptability or versatility
If a flexible face-fitting frame is used, then the comfort for different face shapes is improved, but the stability of the device deteriorates
Solution Approach 1:
The flexible frame incorporates dynamic elements such as hinges and elastic connections that provide both flexibility for adaptation and stability for device support. These dynamic components allow controlled movement and deformation while maintaining overall structural stability when needed.
Solution Approach 2:
The face-fitting frame uses composite material structures combining flexible and rigid elements. This composite design allows different portions of the frame to exhibit different mechanical properties - flexible where adaptation is needed and rigid where structural stability is required - thereby resolving the contradiction between flexibility and stability.
3Manufacturing precision
If a fully connected rigid structure is used, then the manufacturing precision is improved, but the ease of operation and comfort deteriorates
Solution Approach 1:
The face-fitting frame is segmented into multiple independent or semi-independent sections connected by flexible joints or hinges. This segmentation allows each section to be manufactured with high precision independently, while the connections between sections provide the necessary flexibility for easy adjustment and comfort during wearing.
Solution Approach 2:
The segmented structure incorporates dynamic connection elements that allow the frame to adjust to different wearing conditions. These dynamic connections enable easy operation and adjustment by the user while maintaining the manufacturing precision of individual components through standardized connection interfaces.
