Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Method One (manual button adjustment) is used to set deviation limits, then the setting process is simple to understand, but it is time-consuming and inefficient
Solution Approach 1:
The patent replaces the manual button-pressing mechanical operation with an automatic electronic positioning system. The electronic positioning mechanism uses a positioning button that automatically moves the display to the theoretical maximum or minimum deviation value, eliminating the need for repeated manual increment/decrement operations while maintaining ease of use.
2Productivity
If Method Two (physical adjustment to theoretical max/min) is used to set deviation limits, then the operation is faster, but it is difficult to stop at the desired value due to fine resolution
Solution Approach 1:
The patent implements a feedback mechanism where the display shows real-time deviation values during positioning. When the positioning button is pressed, the system automatically moves toward the theoretical max/min value while displaying intermediate values, allowing the user to see when the desired value is reached and stop accordingly. This feedback loop combines the speed of automatic positioning with the precision of visual confirmation.
3Measurement precision
If fine resolution is used in the comparative measuring tool, then measurement precision is improved, but it becomes challenging for users to stop at desired deviation values
Solution Approach 1:
The patent introduces an intermediary electronic positioning mechanism that bridges the gap between fine resolution measurement capability and user-friendly deviation limit setting. The positioning button acts as an intermediary that automatically navigates through the fine resolution steps to reach target values, eliminating the need for users to manually count through each fine resolution increment while preserving the tool's high measurement precision.
