Electronic Device Housing Movable Connections
Solution Overview
Problem
Conventional electronic device housings face challenges in preventing distortion due to minute displacements caused by external forces, heat, and residual stresses, leading to deflections and irregularities, particularly when multiple housing members are combined.
Innovation Solution
The design incorporates movable connecting structures between housing members, allowing for relative displacement within a predetermined range, which helps suppress deflections and distortion by positioning fixing structures centrally and connecting structures closer to the ends, utilizing screws and recessed portions for secure yet flexible connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If housing members are combined to construct the housing, then the housing can be assembled easily and disassembled for repair, but minute displacements caused by external forces, heat, and residual stresses cause deflections and distortion
Solution Approach 1:
The connecting structure is designed to allow movable connection between housing members instead of rigid fixed connection. The movable connecting structure enables the housing members to adjust their positions relative to each other, accommodating thermal expansion and contraction while preventing distortion. This dynamic connection allows the housing to maintain structural integrity during assembly and disassembly while preventing minute displacements from causing deflections.
2Stability of the object's composition
If fixing structures are positioned centrally to suppress distortion, then structural stability is improved, but the complexity of the housing structure increases
Solution Approach 1:
The fixing structure and connecting structure are merged into a single integrated structure. The fixing structure includes both a fixed connection portion that provides structural stability and a movable connection portion that allows adjustment. This merging eliminates the need for separate fixing and connecting structures, reducing overall housing structure complexity while maintaining both stability and adaptability.
3Manufacturing precision
If movable connecting structures are used to allow relative displacement, then distortion is suppressed, but the connection strength between housing members decreases
Solution Approach 1:
The connecting structure has different local properties: the fixed connection portion provides strong rigid connection for structural stability, while the movable connection portion allows displacement to prevent distortion. This local differentiation of connection properties within the same structure enables simultaneous achievement of strong connection and distortion prevention.
Solution Approach 2:
The connecting structure functions as a composite connection system combining both fixed and movable connection characteristics. This composite approach allows the structure to exhibit both rigid strength where needed and flexible adaptability where thermal expansion and contraction occur, maintaining overall connection strength while preventing distortion.
