Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single operation member is used to switch between left and right diopter adjustment and focusing, then the device complexity is reduced, but the ease of operation deteriorates due to complicated switching operations and potential erroneous adjustments
Solution Approach 1:
The invention divides the focusing control into separate operation members for the first optical system and second optical system. Each operation member independently controls its corresponding optical system, eliminating the need for switching operations and reducing the risk of erroneous adjustments while maintaining relatively simple device structure.
2Ease of operation
If separate operation members are used for each optical system focusing, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The invention employs operation members that can control both the first and second optical systems through a unified control mechanism. The operation members are designed to independently adjust each optical system while being part of an integrated focusing control structure, achieving simple operation without proportionally increasing device complexity.
3Device complexity
If manual switching between left and right diopter adjustment and focusing is performed, then the device complexity is reduced, but the reliability deteriorates due to potential erroneous operation
Solution Approach 1:
The invention implements independent automatic focusing control for each optical system through dedicated operation members. Each optical system can be focused independently without requiring manual switching or user intervention to select between diopter adjustment and focusing modes, eliminating erroneous operation while maintaining relatively simple control mechanism complexity.
