Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the first prism, lens module, and second prism are integrally formed in a single body, then the structural integrity is improved, but the optical axis alignment between components deteriorates
Solution Approach 1:
The camera module divides the integrated structure into separate assemblies: a first assembly containing the first prism and lens module, a second assembly containing the second prism, and a third assembly containing the image sensor. These separate assemblies are then coupled together through bonding portions, allowing independent positioning and optical axis alignment of each component while maintaining overall structural integrity.
2Ease of manufacture
If the camera module uses a rigid integrated structure, then the manufacturing simplicity is improved, but the adaptability to narrow installation spaces deteriorates
Solution Approach 1:
By segmenting the camera module into multiple detachable assemblies that can be coupled together, the design achieves both manufacturing simplicity and adaptability. Each assembly can be manufactured separately and then assembled, allowing the overall structure to be configured for narrow installation spaces while maintaining ease of manufacture through standardized bonding portions.
Solution Approach 2:
The camera module transitions from a completely rigid integrated structure to a semi-dynamic assembly structure where components can be positioned and aligned during assembly. The bonding portions allow for controlled movement and adjustment during the assembly process, enabling adaptation to narrow spaces while maintaining structural stability once assembled.
3Manufacturing precision
If bonding portions of different sizes are used between assemblies, then the alignment precision is improved, but the device complexity increases
Solution Approach 1:
The bonding portions are designed with different sizes at specific locations to provide alignment precision where needed. The first bonding portion and second bonding portion have different sizes to enable precise optical axis alignment between the first assembly and second assembly. This localized variation in bonding portion size achieves high alignment precision without requiring the entire assembly structure to be complex, as only the bonding interfaces have the differentiated design.
