Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lens-based anti-shake is used, then image stabilization is achieved, but device complexity increases and anti-shake force is limited
Solution Approach 1:
The patent replaces the traditional lens-based mechanical anti-shake system with an electromagnetic driving module that directly moves the photosensitive chip module. This substitution eliminates the need for complex lens moving mechanisms while achieving the same image stabilization effect through electromagnetic actuation of the sensor platform.
Solution Approach 2:
Instead of moving the lens to compensate for hand shake as in conventional systems, this patent inverts the approach by moving the photosensitive chip module in the opposite direction to counteract the shake. This inversion simplifies the mechanical structure while maintaining the anti-shake functionality.
2Reliability
If lens-based anti-shake is used, then image stabilization is achieved, but anti-shake force is small
Solution Approach 1:
The electromagnetic driving module provides direct electromagnetic force to move the photosensitive chip module, generating significantly larger anti-shake force compared to the subtle mechanical adjustments possible with lens-based systems. The electromagnetic actuation enables more powerful and responsive compensation for hand shake.
3Device complexity
If photosensitive chip module is moved for anti-shake, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The electromagnetic driving module enables precise control of the photosensitive chip module position through electromagnetic field regulation. This electronic control mechanism provides finer positioning precision and easier adjustment compared to mechanical lens moving systems, allowing for accurate anti-shake compensation while maintaining manufacturing feasibility.
