Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If special lenses are disposed in the camera lens assembly for imaging under special conditions, then the imaging capability under special conditions is improved, but the length of the optical system becomes larger, the weight of the camera lens assembly increases, and the manufacturing cost rises
Solution Approach 1:
The patent divides the lens system into two separable parts: the basic camera lens assembly and detachable extension adapters. Each extension adapter contains specific special lenses for particular imaging conditions. This segmentation allows users to attach only the required adapter when needed, avoiding the need to include all special lenses permanently in the main assembly, thus reducing the optical system length when special lenses are not required.
Solution Approach 2:
The patent implements a dynamic lens configuration where the optical system can be reconfigured by attaching or detaching extension adapters based on imaging requirements. The lens assembly transitions from a fixed configuration to a dynamic, adaptable system that changes its composition according to the specific imaging task, optimizing the optical path length for each scenario.
2Adaptability or versatility
If special lenses are disposed in the camera lens assembly for imaging under special conditions, then the imaging capability under special conditions is improved, but the weight of the camera lens assembly increases
Solution Approach 1:
The patent segments the lens system into a lightweight base camera lens assembly and separate extension adapters containing special lenses. Users only carry and attach the heavier extension adapters when specific imaging conditions are required, reducing the overall weight during normal operation while maintaining full imaging capability when needed.
Solution Approach 2:
The patent extracts the special lenses from the main camera lens assembly and places them in detachable extension adapters. This extraction removes the unnecessary weight of special lenses from the permanent configuration, allowing the base assembly to remain lightweight while preserving access to special imaging capabilities through optional attachment.
3Adaptability or versatility
If special lenses are disposed in the camera lens assembly for imaging under special conditions, then the imaging capability under special conditions is improved, but the manufacturing cost rises
Solution Approach 1:
The patent divides the lens system into modular components that can be manufactured separately and assembled as needed. The base camera lens assembly is produced independently, and extension adapters with special lenses are manufactured separately. This segmentation allows for more efficient production, inventory management, and reduces the complexity of manufacturing a single integrated system with all possible special lenses built-in.
Solution Approach 2:
The patent creates a universal mounting interface and communication protocol that allows different extension adapters to be attached to the same camera lens assembly. This multi-functionality enables a single base assembly to work with multiple types of extension adapters, reducing the need to manufacture multiple specialized assemblies for different imaging conditions, thereby lowering overall manufacturing costs.
4Ease of operation
If the camera lens assembly communicates with the camera body and controls movement of optical lenses by itself, then the imaging status can be displayed intuitively, but the device complexity increases
Solution Approach 1:
The patent enables the extension adapter to be self-sufficient with its own processor, memory, and communication unit. The adapter can independently receive imaging status information from the camera body, process this information, and control the focusing lens movement without requiring complex integration with the main camera body. This self-service capability simplifies the overall system architecture by distributing intelligence to the adapter level.
Solution Approach 2:
The patent introduces a communication unit in the extension adapter that acts as an intermediary between the camera body and the focusing lens. This communication unit receives signals from the camera body, processes them locally using the adapter's processor, and generates appropriate control signals for the focusing lens. This intermediary layer simplifies the interface requirements and reduces the complexity of direct integration between the camera body and lens control mechanisms.
