Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If camera modules are coupled to mechanical member using traditional mounting methods, then assembly is straightforward, but coupling strength is insufficient
Solution Approach 1:
The patent merges the camera module housing with the mounting structure by integrating the housing into the mechanical member. The housing includes a mounting portion that directly couples with the mechanical member, eliminating the need for separate mounting brackets or additional fastening components. This integration strengthens the coupling while simplifying the overall mounting structure.
Solution Approach 2:
The patent extends the mounting portion from a traditional surface-mounted configuration to a three-dimensional structure that protrudes from the housing. The mounting portion includes a mounting surface and coupling portions that engage with the mechanical member in multiple dimensions, providing enhanced coupling strength through distributed contact areas and geometric interlocking.
2Manufacturing precision
If optical axis adjustment is performed after module assembly, then alignment can be corrected, but adjustment precision is difficult to achieve
Solution Approach 1:
The patent performs optical axis adjustment during the module assembly process itself, before final coupling to the mechanical member. The imaging element is positioned and adjusted on the housing, allowing optical axis alignment to be established while the module is still accessible and adjustable. This preliminary adjustment ensures precision is achieved at the optimal stage, avoiding difficult post-assembly corrections.
3Adaptability or versatility
If multiple camera modules are arranged with predetermined distance, then 3D imaging capability is achieved, but structural stability is reduced
Solution Approach 1:
The patent merges multiple camera modules into a single integrated imaging device by coupling them to a common mechanical member. The housing of each module is integrated with the mechanical member, creating a unified structure that maintains the predetermined distance between modules while providing overall structural stability through the shared mechanical framework.
Solution Approach 2:
The mechanical member serves multiple functions: it positions the camera modules at the required predetermined distance for 3D imaging, provides structural support and stability, and enables coupling of multiple modules simultaneously. This multi-functional design achieves both the versatility needed for 3D imaging and the stability required for structural integrity.
