Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photographic accessories, such as handles and shoulder mounts, cannot be quickly rotated to adjust the shooting angle of photographic devices, failing to meet user demands for quick angle adjustments.
Innovation Solution
A rotating assembly with a housing, annular retaining frames, elastic members, and unlocking assemblies that allow for quick rotation and adjustment of the shooting angle, featuring rolling members that move towards or away from the axis of the through hole, driven by an unlocking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional locking mechanisms are used in photographic accessories, then the device structure is simple, but the shooting angle cannot be quickly adjusted
Solution Approach 1:
The patent applies the dynamics principle by designing a locking mechanism that can dynamically switch between locked and unlocked states. The elastic member (spring) enables the rolling members to automatically move between engagement and disengagement positions, allowing the device to transition from a static simple structure to a dynamic system that provides quick adjustment capability while maintaining structural simplicity.
Solution Approach 2:
The elastic member drives the rolling members to automatically engage with or disengage from the external shaft without requiring manual intervention for each adjustment. When the operating member is actuated, the elastic member propels the rolling members to move toward or away from the shaft, enabling self-service locking and unlocking that speeds up adjustment while keeping the mechanism simple.
2Ease of operation
If a quick-release mechanism is implemented, then the shooting angle can be quickly adjusted, but the device structure becomes complex
Solution Approach 1:
The patent merges multiple functions into a single integrated mechanism. The rolling members serve dual purposes: they act as locking elements when engaged with the external shaft and as positioning elements when disengaged. The elastic member combines both the driving force for engagement and the resetting force for disengagement, eliminating the need for separate locking and releasing mechanisms, thus improving ease of operation without significantly increasing complexity.
Solution Approach 2:
The operating member serves multiple functions: it actuates the unlocking assembly, controls the movement of rolling members, and initiates the locking or unlocking state. This multi-functional design reduces the number of separate components needed, making the quick-adjustment mechanism more compact and less complex while maintaining ease of operation.
3Productivity
If rolling members are added to enable quick rotation, then the adjustment speed improves, but the device size increases
Solution Approach 1:
The rolling members are nested within the locking assembly structure, with the elastic member positioned inside the housing and the rolling members contained within the locking assembly. This nested arrangement allows the quick-rotation mechanism to be compact, minimizing the increase in device volume while enabling fast adjustment through the rolling members' movement.
Solution Approach 2:
The rolling members move in a radial direction toward or away from the external shaft axis, utilizing the radial dimension rather than increasing the axial or circumferential dimensions. This dimensional approach allows the locking and unlocking function to be achieved within a compact space, improving rotation speed without significantly increasing the overall device size.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and convenient adjustment of the shooting angle by allowing the photographic device to be quickly rotated and locked, enhancing user convenience and reducing the overall size of the photographic device.
Implementation Method 1
The elastic member is connected to the two annular retaining frames to drive the rolling members to move toward to the axis of the through hole
Implementation Method 2
The rolling members move toward to or away from an axis of the through hole as the annular retaining frames rotate... allowing the external shaft to rotate freely within the through hole

AI summary
The present disclosure discloses a composite bearing. The composite bearing includes a housing, two locking assemblies, a transmission assembly, and an unlocking assembly. The housing is defined with a mounting hole. The two locking assemblies are rotatably arranged in the mounting hole in sequence, both two locking assemblies are defined with a through hole configured to mount an external shaft. A side wall of the locking assemblies is provided with rolling members located between an inner wall of the mounting hole and the external shaft. The transmission assembly is connected to the two locking assemblies respectively so that the two locking assemblies may clamp the external shaft in the through hole. The unlocking assembly is connected to the two locking assemblies respectively to drive the two locking assemblies to release the external shaft. In the present disclosure makes it convenient for users to quickly adjust the desired shooting angle.
