Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional direct measurement methods are used for each cutter holder, then measurement accuracy can be maintained, but measurement time and operational complexity increase significantly due to the large number of cutter holders
Solution Approach 1:
The patent introduces a measuring tool as an intermediary device that includes a positioning pin and base with positioning point. The positioning pin inserts into the mounting hole of the cutter holder, and the base provides a positioning point for the detecting device. This intermediary measuring tool enables indirect measurement of cutter holder pose parameters, significantly reducing measurement time while maintaining accuracy through the detecting device that captures images of the positioning point from multiple angles.
2Measurement precision
If traditional direct measurement methods are used for each cutter holder, then measurement accuracy can be maintained, but operational convenience and efficiency deteriorate due to the large number of cutter holders requiring measurement
Solution Approach 1:
The measuring tool serves as a convenient intermediary that simplifies the measurement operation. The operator simply needs to insert the positioning pin into the cutter holder's mounting hole and attach the measuring tool, then the detecting device automatically captures images of the positioning point. This eliminates the need for complex direct measurement operations on each cutter holder individually.
Solution Approach 2:
The measuring tool creates a standardized measurement interface by using a positioning point on its base that corresponds to the cutter holder's mounting hole. The detecting device captures images of this positioning point to determine pose parameters, effectively copying the measurement process into a standardized, repeatable operation that is much easier to perform than direct measurements.
3Productivity
If a simplified measurement method is used to reduce measurement time, then productivity improves, but measurement precision may deteriorate
Solution Approach 1:
The measuring tool as an intermediary maintains precision by using a positioning pin that precisely fits into the mounting hole and a base with a positioning point that serves as a reference for the detecting device. The detecting device captures images from multiple angles to calculate three-dimensional coordinates, ensuring accurate pose parameter measurement while enabling efficient batch measurement of multiple cutter holders.
