Actuator Locking Mechanism for Image Capture Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capture devices with actuators are susceptible to motion artifacts such as shakiness and wobbling due to inherent ability to move, which can cause vibrations and affect image or video capture quality, especially during high-intensity activities.
Innovation Solution
A system and method that includes an actuator locking mechanism to secure the lens barrel within a barrel mount, using a compressible component and cam system to apply forces along the central axis, preventing unwanted movement of the lens barrel and barrel mount, thereby stabilizing the image capture device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an actuator is used to adjust lens barrel position for calibration and focus correction, then manufacturing precision and adaptability are improved, but the device becomes susceptible to vibration and motion artifacts that worsen image capture quality
Solution Approach 1:
The system dynamically switches between two states: a locked state where the actuator locking mechanism secures the lens barrel to prevent vibration during image capture, and an unlocked state where the actuator can adjust the lens barrel position for calibration or focus correction. This dynamic switching resolves the contradiction by allowing the system to have both adjustability and stability at different operational phases.
Solution Approach 2:
The actuator locking mechanism extracts and isolates the lens barrel from the actuator's movement capability during capture operations. By physically decoupling the lens barrel from the actuator through the locking mechanism, the system eliminates the source of vibration and motion artifacts while preserving the actuator's ability to adjust position when needed for calibration or focus correction.
2Stability of the object's composition
If the lens barrel is secured with a locking mechanism to prevent motion, then stability during capture is improved, but the ability to adjust focus and calibration is reduced
Solution Approach 1:
The system employs dynamic control of the locking mechanism, transitioning between locked and unlocked states based on operational requirements. During image capture, the locking mechanism is engaged to provide stability. For focus adjustment or calibration operations, the locking mechanism is disengaged to allow the actuator to move the lens barrel. This temporal separation of locking and adjustment functions resolves the contradiction between stability and adaptability.

Function Achieved in This Case
The actuator locking mechanism effectively prevents motion artifacts, ensuring stable image and video capture by locking the lens barrel in place, even during high-intensity activities, while still allowing for adjustable focus and calibration as needed.
