Image Stabilizer Handle Status Control to Stop Free Swing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image stabilization apparatuses experience uncontrolled swings of the handle when the user fails to hold it, leading to disturbances in photography and potential damage to the apparatus due to continuous motor rotation and collision with position limiting mechanisms.
Innovation Solution
A method and apparatus that detect the motion status of the handle, specifically identifying when it is in a free status, and control the rotary axis motor to stop rotating in such cases, preventing uncontrolled swings and potential damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the negative feedback system continuously rotates the motor to suppress shaking, then image stabilization is improved, but the handle experiences uncontrolled swings and potential damage occurs
Solution Approach 1:
The system uses a sensor to detect handle status and feeds this information back to the controller, which then adjusts motor operation accordingly. When the handle is detected as not being held, the controller stops the motor to prevent uncontrolled swings and damage, while maintaining image stabilization when the handle is properly held.
2Stability of the object's composition
If the rotary axis motor rotates continuously to maintain stabilization, then photographing stability is improved, but the handle may collide with position limiting mechanisms causing damage
Solution Approach 1:
The system proactively detects when the handle is not being held and preemptively stops the motor before uncontrolled rotation can occur. This prevents the handle from swinging uncontrollably and colliding with position limiting mechanisms, thereby protecting the apparatus from damage while maintaining photographing stability when properly operated.

AI summary
A method for controlling an image stabilization apparatus includes detecting a motion status of a handle of the image stabilization apparatus. A rotation of the handle is controlled by a rotary axis motor of the image stabilization apparatus. The method further includes controlling the rotary axis motor to stop rotating in response to the motion status of the handle being a free status in which the handle is not fixed and one portion of the image stabilization apparatus other than the handle is fixed.
