Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bracket structure is fixed and rigid, then the structural stability is improved, but the measurement accuracy deteriorates due to angular offsets between components
Solution Approach 1:
The patent applies the dynamics principle by making the bridge structure rotatable relative to the first support part through a stop mechanism. This allows the system to transition from a fixed state to an adjustable state, enabling angular offset elimination while maintaining structural stability during operation. The rotatable structure permits dynamic adjustment of the bridge structure's angle to achieve precise alignment with the second support part.
2Device complexity
If the bridge structure is fixed relative to the first support part, then the device complexity is reduced, but the adaptability deteriorates due to inability to adjust angular alignment
Solution Approach 1:
The stop mechanism enables dynamic adjustment of the bridge structure's angular position relative to the first support part. This provides adaptability for different measurement requirements while maintaining relatively simple device complexity through a straightforward rotational joint design with stopping positions.
3Measurement precision
If the rotatable structure is added to allow rotation, then the measurement accuracy is improved by eliminating angular offsets, but the device complexity increases
Solution Approach 1:
The rotatable structure with stop mechanism provides a relatively simple dynamic adjustment system that enables precise angular alignment to eliminate measurement errors, achieving improved measurement accuracy with moderate increase in device complexity.
