Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a friction-based locking mechanism is used to fix the rotating members, then the rotational position can be held securely, but significant manual effort is required to press or release the damping sheet for angle adjustment
Solution Approach 1:
The elastic component automatically pushes the first and second rotating members apart after the damping sheet is pressed, eliminating the need for continuous manual force to maintain the unlocked state. The system self-regulates the separation force, providing automatic resetting functionality that reduces operational effort while maintaining reliable locking when engaged.
Solution Approach 2:
The mechanism transitions from a static friction-based hold to a dynamic system where the elastic component continuously adjusts the separation between rotating members. This dynamic adjustment allows easy release of the locking state by simply pressing the damping sheet, as the elastic force automatically restores the separated position once the pressing force is removed.
2Reliability
If a thrust device is used to press the damping sheet for locking, then the rotational members can be fixed, but the device complexity increases due to additional components
Solution Approach 1:
The complex thrust device is replaced by extracting only the essential elastic pushing function. The elastic component directly provides the separation force between rotating members without requiring intermediate transmission mechanisms, simplifying the overall structure while maintaining the ability to achieve stable locking through the damping sheet pressing action.
Solution Approach 2:
The elastic component serves as a simple intermediary between the rotating members, providing the necessary separation force without complex mechanics. This intermediary element replaces the entire thrust device, reducing structural complexity while ensuring reliable locking through the damping sheet friction mechanism.

Function Achieved in This Case
Facilitates effortless angle adjustment of photographic equipment by reducing manual labor, improving operational convenience, and ensuring stable connections through automatic resetting and detachable components.
Implementation Method 1
an elastic component, configured to push the first rotating member and the second rotating member away from each other
Implementation Method 2
the first rotating member and the second rotating member simultaneously press the damping sheet between them, and by pressing the damping sheet, rotating friction of them relative to the damping sheet is increased

AI summary
A rotating module includes a fixing member, a telescopic member, a rotating member and a driving member. The fixing member is provided with a first connecting hole recessed from a first end of the fixing member, and a first locking part arranged at the first end of the fixing member. The telescopic member is partially disposed through the first connecting hole and capable of sliding in the first connecting hole, and its first end penetrates out of the fixing member from the first end of the fixing member. The rotating member is rotatably connected to the first end of the telescopic member and its first end faces the first end of the fixing member and is provided with a second locking part. A first end of the driving member extends into an interior of the fixing member and is rotatably connected with a second end of the telescopic member.
