Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the camera module uses traditional rigid substrate connections, then structural stability is maintained, but mounting space is reduced and cable adaptability is limited
Solution Approach 1:
The substrate is divided into a rigid substrate and a flexible substrate that are separately connected. The rigid substrate provides structural stability while the flexible substrate enables cable adaptability. This segmentation allows the camera module to accommodate different cable specifications without compromising structural integrity, thereby increasing mounting space and improving cable adaptability simultaneously.
Solution Approach 2:
The flexible substrate introduces a new dimension of flexibility to the traditionally rigid substrate structure. By adding this flexible dimension, the camera module can adapt to various cable specifications without requiring changes to the overall camera configuration, thus resolving the contradiction between mounting space and cable adaptability.
2Volume of moving object
If the camera module is miniaturized, then convenience for automobile mounting is improved, but the space for mounting necessary parts is reduced
Solution Approach 1:
By segmenting the substrate into rigid and flexible components, the design optimizes space utilization. The rigid substrate maintains structural stability allowing for miniaturization, while the flexible substrate provides necessary mounting area for parts and cable connections, thus enabling compact size without sacrificing mounting space.
Solution Approach 2:
The flexible substrate acts as a thin film that provides necessary mounting functionality without adding significant volume. This allows the camera module to be miniaturized while still accommodating all necessary parts and connections.
3Adaptability or versatility
If the camera configuration is changed to accommodate different cables, then cable adaptability is improved, but device complexity increases
Solution Approach 1:
The flexible substrate with cable connection functionality is extracted as a separate, replaceable component. This allows different cable specifications to be accommodated by simply changing the flexible substrate or cable assembly without modifying the main camera configuration, thereby improving adaptability while maintaining simplicity.
Solution Approach 2:
The rigid substrate is designed with universal mounting features that can accommodate various cable types through the flexible substrate interface. This universal design allows the same camera configuration to work with different cable specifications, improving adaptability without increasing complexity.
