Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional eccentric wheel mechanisms are used for pan-tilt quick locking, then reliable locking function is achieved, but device volume and structural complexity increase
Solution Approach 1:
The patent extracts the essential locking function from the complex eccentric wheel mechanism, retaining only the necessary components (locking ring with positioning holes, elastic positioning members, and sliding slots) while eliminating unnecessary mechanical elements. This extraction maintains reliable locking while significantly reducing device volume and structural complexity.
Solution Approach 2:
The patent replaces the traditional mechanical eccentric wheel system with a simplified mechanism using elastic positioning members that slide into positioning slots. This substitution eliminates complex linkages and reduces the overall mechanical system size while maintaining the quick locking and releasing functions.
2Reliability
If traditional eccentric wheel mechanisms are used for pan-tilt quick locking, then reliable locking function is achieved, but device complexity increases
Solution Approach 1:
The patent extracts the essential locking function from the complex eccentric wheel mechanism, retaining only the necessary components (locking ring with positioning holes, elastic positioning members, and sliding slots) while eliminating unnecessary mechanical elements. This extraction maintains reliable locking while significantly reducing device volume and structural complexity.
Solution Approach 2:
The patent merges multiple functions into integrated components. The locking ring simultaneously provides structural support, defines the locking path through its geometry, and contains the positioning holes that guide the elastic members. This merging reduces the number of separate parts and simplifies the overall structure while maintaining reliable locking functionality.
3Ease of operation
If traditional quick locking devices are used, then locking function is achieved, but operating space requirement increases
Solution Approach 1:
The patent employs a nested structure where the elastic positioning members are contained within the locking ring's inner cavity. The positioning members slide within predefined slots, and the entire mechanism is compactly arranged to minimize the operating space required for quick locking and releasing operations.
Solution Approach 2:
The patent transitions from planar eccentric wheel motion to a three-dimensional sliding mechanism where elastic members move along vertical slots within the locking ring's inner cavity. This dimensional change allows the locking mechanism to operate in a compact vertical space rather than requiring larger horizontal operating area.
4Weight of stationary object
If smaller and lighter photographing instruments are used, then instrument size and weight are reduced, but compatibility with existing locking devices decreases
Solution Approach 1:
The patent designs a universal locking mechanism with a standardized locking ring structure that can accommodate various sizes of photographing instruments. The adjustable positioning holes and elastic members allow the same basic mechanism to work with different instrument weights and dimensions, ensuring compatibility across smaller and lighter photographing equipment while maintaining secure locking.
