Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic driving mechanisms are used for shutter control and inclination adjustment, then the camera can be controlled accurately, but the design becomes complicated and costs increase
Solution Approach 1:
The patent replaces electronic driving mechanisms with a purely mechanical linkage system. The knob cover's rotational movement is converted into linear movement of the shielding structure through a linkage mechanism, eliminating the need for electronic motors, sensors, and control circuits while maintaining precise control over shutter opening/closing and inclination adjustment.
Solution Approach 2:
The patent introduces a linkage mechanism as an intermediary between the knob cover and the shielding structure. This mechanical intermediary translates the rotational motion of the knob cover into the desired linear and angular movements of the shielding structure, achieving precise control through mechanical geometry rather than electronic actuation.
2Extent of automation
If electronic driving mechanisms are used for shutter control and inclination adjustment, then the camera functions can be automated, but manufacturing costs increase
Solution Approach 1:
The patent replaces expensive electronic driving components (motors, controllers, sensors) with inexpensive mechanical linkages and geometric constraints. The automation is achieved through pure mechanical design where the knob cover's rotation automatically drives the shielding structure through predetermined geometric relationships, dramatically reducing manufacturing costs while maintaining automated functionality.
Solution Approach 2:
The mechanical linkage system is designed to be self-actuating through the user's manual rotation of the knob cover. The geometric configuration of the linkage automatically performs the shutter opening/closing and inclination adjustment without requiring electronic power sources, control systems, or complex assembly, making the system self-sufficient and cost-effective.
3Ease of manufacture
If a simple mechanical design is used for shutter control, then costs are reduced, but the precision of control may be compromised
Solution Approach 1:
The patent employs curved surfaces and arc-shaped pathways in the mechanical linkage design. The knob cover rotates along a precise arc, and the linkage is configured with curved guide surfaces that ensure accurate translation of this rotational motion into linear and angular movements of the shielding structure. This geometric precision ensures accurate control without requiring complex electronic systems.
Solution Approach 2:
The mechanical linkage is divided into multiple precision-engineered segments connected at specific joints. Each segment is designed with predetermined dimensions and angles that collectively achieve the desired precise control. The segmentation allows for modular assembly while maintaining overall precision through careful design of each segment's geometric relationships.
