Camera Stabilizer Linkage With Bidirectional Rotation Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capture accessories for electronic devices lack a mechanism to freely fix and release the rotation portion regardless of the rotation direction, which hinders effective correction of device shaking during image capture.
Innovation Solution
An image capture assisting accessory with a coupling part, link rods, and correction parts that include a fixing portion, a rotation portion, and a rotation lock, allowing for the absorption of device displacement and restriction of rotation to prevent shaking, using a motor and slip ring for power and signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotation lock mechanism is added to restrict rotation of the rotation portion, then device shaking is corrected and image quality is improved, but device complexity increases
Solution Approach 1:
The rotation lock mechanism is designed to dynamically switch between locked and unlocked states based on operational needs. The spring component provides automatic engagement/disengagement based on rotational force applied, allowing the system to adapt between stability (locked) and flexibility (unlocked) without permanent structural complexity
Solution Approach 2:
The spring-based rotation lock mechanism automatically engages when rotation exceeds a certain threshold and disengages when force is applied in the opposite direction. This self-regulating mechanism eliminates the need for external control systems, sensors, or power sources, reducing overall device complexity while maintaining reliability
2Reliability
If the rotation portion can be freely fixed and released regardless of rotation direction, then shaking correction is improved, but ease of operation becomes more difficult
Solution Approach 1:
The spring mechanism automatically detects when rotational force exceeds the locking threshold and engages the lock in either direction. Users simply need to apply force to rotate the rotation portion, and the system self-regulates without requiring users to understand or control the locking mechanism, maintaining ease of operation while improving shaking correction
3Reliability
If the rotation lock restricts rotation to prevent damage, then device protection is improved, but adaptability decreases
Solution Approach 1:
The rotation lock transitions from a static restricted state to a dynamic system that adapts to user needs. When protection is needed, the spring automatically engages; when flexibility is needed, users can apply force to disengage it. This dynamic behavior provides both device protection and rotation flexibility without compromising either
Solution Approach 2:
The system changes the rotational parameter from completely free to restricted by introducing a spring-based mechanical threshold. This parameter change allows the system to protect against excessive rotation while still permitting controlled rotation within safe limits, maintaining adaptability while improving protection
