Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in achieving high optical anti-shake accuracy due to integrated control modules that cannot be adjusted, leading to low anti-shake performance in certain scenarios, such as motor resonance and magnetic interference.
Innovation Solution
The control module is arranged on a separate main board, allowing for independent control of the anti-shake motor assembly based on the device's motion state, improving accuracy and reducing costs by avoiding integration issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the control module is integrated into the camera module, then the device structure is simplified, but the optical anti-shake accuracy deteriorates due to motor resonance and magnetic interference
Solution Approach 1:
The patent divides the control system into separate modules: the control module is positioned on the main board while the anti-shake motor assembly is integrated into the camera module. This spatial segmentation isolates the control electronics from the motor assembly, preventing magnetic interference and resonance coupling, thereby maintaining anti-shake accuracy while preserving structural simplicity.
2Ease of manufacture
If the control module is integrated into the camera module, then the manufacturing cost is reduced, but the anti-shake performance deteriorates in certain scenarios
Solution Approach 1:
The patent implements a segmented architecture where the control module remains on the main board rather than being integrated into the camera module. This separation prevents harmful magnetic interference and resonance effects, ensuring reliable anti-shake performance while maintaining cost-effectiveness through standardized module design and assembly.
3Measurement precision
If the control module is separated from the camera module, then the optical anti-shake accuracy is improved, but the device complexity increases
Solution Approach 1:
The control module on the main board serves multiple functions: it controls not only the anti-shake motor assembly but also manages other device operations. This multi-functionality approach justifies the separate placement by maximizing the utility of the control module, thereby managing overall device complexity while maintaining improved anti-shake accuracy.
