Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple feeler members are used to control deviation along two axes, then alignment control precision is improved, but device complexity and bulk increase
Solution Approach 1:
The patent combines multiple feeler members into a single feeler member that can detect deviations along both the first axis (X-axis) and the second axis (Y-axis). This single feeler member integrates the functionality of what would traditionally require multiple separate devices, thereby reducing device complexity while maintaining alignment control precision through centralized measurement capability.
2Measurement precision
If multiple devices are used to check alignment along two axes, then measurement accuracy is improved, but the bulk and control process complexity increase
Solution Approach 1:
The single feeler member is designed with multi-functional capability to detect deviations along both the first axis and the second axis simultaneously. This universal measurement approach allows one device to perform the work of multiple specialized devices, reducing control process complexity while maintaining measurement accuracy through integrated detection of multi-directional deviations.
3Device complexity
If a single measuring device is used to measure workpiece position, then device complexity is reduced, but measurement precision may be compromised
Solution Approach 1:
The single feeler member is segmented into multiple detection points or measurement zones that can independently detect deviations along different axes. By incorporating multiple sensing elements within one integrated structure, the device maintains measurement precision equivalent to multiple separate devices while avoiding the complexity of multiple independent systems.
