Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a simple holder structure is used, then the device complexity is reduced, but the rigidity of the holder is insufficient
Solution Approach 1:
The holder is segmented into distinct functional parts: a base portion for mounting, a bending part for structural reinforcement, and a coupling part for attaching the back cover. This segmentation allows each part to be optimized for its specific function while maintaining overall rigidity without excessive complexity
Solution Approach 2:
The holder incorporates a bending part with curved geometry that extends from the base. This curved structure provides structural reinforcement and rigidity while distributing stresses more effectively than straight lines, enhancing strength without proportionally increasing complexity
2Stability of the object's composition
If conventional coupling structures are used, then the ease of manufacture is improved, but thermal deformation cannot be minimized
Solution Approach 1:
The coupling part is designed with specific geometric parameters including a curled configuration and defined contact area with the back cover. These parameter changes optimize the thermal expansion characteristics and mechanical coupling strength, reducing thermal deformation while maintaining manufacturability through standard forming processes
3Strength
If a rigid coupling structure is used, then the holder rigidity is improved, but EMI noise increases
Solution Approach 1:
The coupling part employs a flexible curved design that can slightly deform under thermal stress or vibration. This flexibility acts as a mechanical filter for high-frequency vibrations and electromagnetic interference, reducing EMI noise transmission while maintaining sufficient structural rigidity for device assembly
Solution Approach 2:
The bending part serves as an intermediary element between the rigid base and the back cover coupling. This intermediate curved structure decouples direct rigid connections, reducing the transmission path for EMI noise while still providing the necessary mechanical support and positioning
