Engineering Contradiction Analysis
1Measurement precision
If a single sensor with small detection range is used for measurement, then measurement precision can be high, but measurement time increases and productivity decreases
Solution Approach 1:
The measurement task is segmented into two phases: an initial overview measurement phase using a first sensor to capture the entire component, and a detailed measurement phase using a second sensor with higher precision for specific regions of interest. This segmentation allows the system to balance between coverage speed and measurement precision, avoiding the need to use the high-precision sensor for the entire component.
Solution Approach 2:
The second sensor with higher measurement precision is applied partially only to specific regions of interest identified in the initial measurement, rather than being applied to the entire component. This partial action approach maintains high precision where needed while avoiding the time penalty of using high-precision measurement for the entire component.
2Measurement precision
If component calibration is performed before measurement, then measurement accuracy improves, but setup time increases
Solution Approach 1:
The first sensor performs a preliminary overview measurement of the entire component to identify its position, orientation, and key features. This preliminary action provides sufficient information to quickly establish a measurement reference frame, enabling the second sensor to perform detailed measurements without requiring time-consuming traditional calibration procedures.
3Quantity of substance
If traditional measurement methods are used for components with deformations, then measurement completeness is maintained, but measurement accuracy decreases
Solution Approach 1:
The measurement system dynamically adapts to component deformations by using the first sensor to capture the actual deformed geometry and then using this information to guide the second sensor's measurement of specific regions. This dynamic approach allows accurate measurement of deformed components without requiring rigid fixtures or pre-machining, maintaining both measurement completeness and accuracy.
