Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the optical component driving mechanism is reduced, then the device becomes more compact and meets modern electronic device trends, but the durability and stability of the driving mechanism deteriorates
Solution Approach 1:
The patent introduces a weighting component with density greater than the fixed portion to counterbalance the movable portion. This weighting component is specifically designed to improve the durability and stability of the driving mechanism while maintaining a compact size. The weighting component acts as a counterweight that enhances the overall reliability of the optical component driving mechanism.
2Speed
If denser weighting components are used, then the moving speed increases and energy consumption decreases, but the device complexity increases
Solution Approach 1:
The patent applies local quality by using a weighting component with specific density properties in a localized position within the driving mechanism. The weighting component is positioned to optimally influence the moving speed and energy consumption without requiring the entire structure to be complex. This localized application of dense material achieves performance improvement while minimizing overall structural complexity.
3Reliability
If the weighting component is added to improve durability, then the reliability increases, but the volume of the mechanism increases
Solution Approach 1:
The weighting component is nested within the existing structure of the optical component driving mechanism. Rather than adding external components that would increase overall volume, the weighting component is integrated into the internal structure, allowing it to be contained within the existing spatial envelope of the mechanism.
