Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ball-type anti-shake mechanism is used, then optical image stabilization is achieved, but friction increases and debris accumulates
Solution Approach 1:
The patent replaces the traditional mechanical ball-type anti-shake mechanism with a moving element that has an inclined lateral surface contacting groove surfaces. This substitution reduces multiple contact points to linear contact, thereby reducing friction and debris accumulation while maintaining the optical image stabilization function
Solution Approach 2:
The patent changes the geometric parameters of the contact surfaces by designing the moving element with an inclined lateral surface that forms specific angles with the groove surfaces. This parameter optimization minimizes friction between contact surfaces while enabling effective anti-shake operation
2Reliability
If multiple contact points are used in ball-type mechanism, then stabilization is provided, but friction increases
Solution Approach 1:
The patent extracts the essential stabilization function from the complex ball-type mechanism with multiple contact points and implements it through a simplified moving element with inclined surfaces. This extraction maintains the stabilization capability while eliminating excessive friction caused by multiple contact points
Solution Approach 2:
The patent optimizes the contact geometry by designing the inclined lateral surface to form specific angles with the groove surfaces, changing the contact parameters from multiple point contacts to optimized linear contacts, thereby reducing friction while maintaining stabilization
