Telescopic Rotating Module With Snap Lock Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary locking mechanisms for photographic equipment require significant manual effort to adjust angles due to friction-based fixing methods, leading to labor-intensive operations.
Innovation Solution
A rotating module with a telescopic member, driving member, and locking parts that allow for easy angle adjustment by swinging the driving member to unlock or lock the rotating member relative to the fixing member, facilitated by a telescopic mechanism and a reset component for automatic relocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a friction-based locking mechanism with a damping sheet is used to fix the rotating members, then the rotating members can be relatively fixed to maintain the photographic equipment angle, but the user needs to spend significant manual effort to drive the thrust device to press or release the damping sheet, resulting in labor-intensive operations
Solution Approach 1:
The patent transforms the static friction-based locking mechanism into a dynamic snap-locking mechanism. The locking part and grooved locking part are designed to engage and disengage through a snapping motion rather than gradual frictional pressing. This dynamic engagement allows the locking and unlocking actions to be completed with minimal manual effort while maintaining reliable fixation when locked.
Solution Approach 2:
The locking mechanism is segmented into distinct components: a locking part with a locking surface, a grooved locking part with corresponding grooves, and a thrust device. This segmentation allows each component to perform its specific function efficiently - the locking surfaces provide secure engagement, the grooves guide the snapping motion, and the thrust device initiates the unlocking action with minimal force.
2Reliability
If a thrust device is used to press the damping sheet for locking, then the rotating members can be fixed, but the structure becomes more complex and requires additional components
Solution Approach 1:
The patent merges the damping sheet function into the locking surfaces themselves. The locking part and grooved locking part are designed with friction surfaces that provide both the locking action and the damping effect in a single integrated structure, eliminating the need for a separate damping sheet component while maintaining locking stability.
Solution Approach 2:
The patent extracts the essential locking function from the complex friction-based mechanism and implements it through a simplified snap-locking action between the locking part and grooved locking part. This extraction removes unnecessary intermediate components like the damping sheet while preserving the core functionality of secure angle fixation.
3Reliability
If manual pressing of the damping sheet is required for each angle adjustment, then the locking mechanism can maintain firm fixation, but the angle adjustment process becomes time-consuming and reduces productivity
Solution Approach 1:
The patent implements periodic snap-locking action where the locking part engages with the grooved locking part in discrete, rapid steps rather than continuous frictional pressing. Each snap action quickly transitions from unlocked to locked state, enabling rapid angle adjustments while maintaining firm fixation at each positioned angle.
Solution Approach 2:
The locking surfaces are pre-configured in specific geometric patterns on the locking part and grooved locking part. This preliminary arrangement of locking surfaces ensures that when the thrust device initiates the unlocking motion, the snap-locking engagement occurs automatically at the correct position, eliminating the need for manual positioning and pressing efforts during adjustment.

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.
