Blur Correction Device Merging Movable Bodies for Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blur correction devices for imaging systems are complex due to the need for multiple moving bodies and actuators, which increases weight and reduces structural simplicity.
Innovation Solution
A blur correction device with a first movable body and a second movable body, each driven by separate drive bodies, allowing for orthogonal movement directions that simplify the structure and reduce weight by integrating movement mechanisms within a single base body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple moving bodies and actuators are used for blur correction, then image stabilization function is achieved, but device complexity and weight increase
Solution Approach 1:
The patent merges the first and second moving bodies into a single integrated movable body that performs both first-direction and second-direction movements. This consolidation reduces the number of separate components while maintaining the dual-directional blur correction functionality, directly addressing the contradiction between achieving image stabilization and reducing device complexity
Solution Approach 2:
The single movable body is designed to perform multiple functions: it can move in the first direction for one type of blur correction and in the second direction for another type of blur correction. This multi-functional design eliminates the need for separate moving bodies for each direction, reducing overall structure complexity while maintaining comprehensive image stabilization capability
2Reliability
If multiple moving bodies are used for blur correction, then image stabilization function is achieved, but device weight increases
Solution Approach 1:
By combining the first and second moving bodies into one integrated movable body, the patent reduces the total weight compared to having separate moving bodies. The unified structure eliminates redundant materials and components while preserving the ability to correct blurs in both directions, directly addressing the weight issue
3Reliability
If multiple moving bodies with contact in movable states are used, then blur correction in orthogonal directions is achieved, but structure simplification is hindered
Solution Approach 1:
The patent integrates the first and second moving bodies into a single movable body, reducing the number of parts from three separate moving bodies to one. This merged structure maintains the capability to move in orthogonal directions through integrated movement mechanisms, directly resolving the contradiction between achieving orthogonal movement and simplifying structure
Solution Approach 2:
Within the single movable body, the patent implements segmented movement mechanisms that can independently control movement in the first direction and second direction. This internal segmentation allows orthogonal direction movement capability while maintaining an externally simplified single-body structure, reducing the overall number of parts

AI summary
To reduce the weight of the movable body while simplifying the structure. Included are: a first movable body that is movable in a first movement direction with respect to a base body; a second movable body that is positioned on an opposite side of the first movable body from the base body and movable in a second movement direction different from the first movement direction with respect to the first movable body; and a first drive body and a second drive body that each apply driving force to the second movable body, in which the first movable body and the second movable body are integrally moved in the first movement direction with respect to the base body by the driving force of at least one of the first drive body or the second drive body, and the second movable body is moved in the second movement direction with respect to the first movable body by the driving force of at least one of the first drive body or the second drive body.
