Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the lens is connected to a frame or to each other to maintain alignment, then the alignment stability is improved, but the ease of replacement deteriorates
Solution Approach 1:
The lens assembly is segmented into a replaceable lens module that can be independently removed from the camera body. The lens module includes the lens element, retaining ring, and spring plate as separate but integrated components that can be exchanged as a unit, while the camera body retains the bayonet mechanism for secure attachment.
Solution Approach 2:
The spring plate provides dynamic elastic deformation to maintain continuous contact pressure between the bayonet fingers and the lens module. This elastic mechanism allows the system to adapt to minor dimensional variations and impacts while maintaining stable alignment, and enables easy release when force is applied.
2Reliability
If the lens is firmly connected within the image capture device, then the alignment maintenance is improved, but the ease of replacement deteriorates
Solution Approach 1:
The spring plate is pre-loaded in an elastic state to continuously exert contact force on the bayonet fingers. This preliminary elastic energy storage ensures that the lens module is firmly held in alignment during operation, while allowing quick release when the user applies sufficient force to overcome the spring pressure.
Solution Approach 2:
The spring plate changes its physical state between compressed and relaxed conditions. During normal operation, the spring is compressed to maintain firm connection and alignment. During replacement, the spring can be temporarily relaxed or overcomed by applied force, allowing the lens module to be removed and reattached.
3Manufacturing precision
If the lens module includes a spring plate that elastically deforms to compress the lens module towards the lens barrel, then the alignment precision is improved, but the device complexity increases
Solution Approach 1:
The spring plate is integrated with the retaining ring as a single piece or closely coupled components, combining the alignment function and the elastic retention function into one compact assembly. This merging reduces the number of separate parts and simplifies the overall structure while maintaining precise alignment through the elastic deformation of the spring plate.
