Composite Bearing Unlocking Assembly for Fast Camera Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photographic accessories, such as handles and shoulder mounts, cannot quickly adjust the shooting angle of photographic devices after being assembled and locked, failing to meet user demands for quick angle adjustments.
Innovation Solution
A rotating assembly with a housing, annular retaining frames, an elastic member, and an unlocking assembly is provided, allowing for quick rotation of the photographic device by using rolling members that move radially within the retaining frames, driven by an unlocking mechanism, enabling easy adjustment of the shooting angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the handle or shoulder mount is assembled and locked, then the structural stability is improved, but the ability to quickly adjust the shooting angle deteriorates
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic unlocked state through the elastic member. When the operating member is actuated, the elastic member deforms and releases the rolling members from the locking position, enabling quick rotation. This dynamic transition resolves the contradiction by allowing the structure to be stable when locked but easily adjustable when needed.
Solution Approach 2:
The elastic member acts as an intermediary between the operating member and the rolling members. It stores energy when deformed and releases it to drive the rolling members away from the shaft, enabling quick unlocking. This intermediary mechanism allows easy operation while maintaining structural stability during normal use.
2Reliability
If a locking mechanism is used to fix the photographic device, then the reliability is improved, but the speed of angle adjustment deteriorates
Solution Approach 1:
The locking mechanism operates in periodic cycles: locked state for stable positioning, unlocked state for quick adjustment. The elastic member enables rapid transition between these states through periodic deformation and release, achieving both reliable locking and fast adjustment speed through repeated cycling between locked and unlocked positions.
Solution Approach 2:
The elastic member is pre-loaded and positioned to ready the rolling members for quick release. When the operating member is actuated, the pre-stored energy in the elastic member immediately drives the rolling members away from the shaft, enabling instant unlocking without requiring forceful manual manipulation, thus achieving both reliability and speed.
3Ease of operation
If rolling members are used to clamp the shaft, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The operating member combines multiple functions: it directly drives the elastic member, which in turn controls both rolling members simultaneously. This merged mechanism reduces the number of separate components and control elements needed, achieving ease of operation without excessive complexity by consolidating the unlocking function into a single integrated system.
