Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If colorimetric detection is performed at multiple predetermined angles, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The detection process is segmented into multiple discrete angle positions (e.g., 0°, 45°, 90°, 135°) around the vehicle component. The detector is positioned at each segment sequentially to capture colorimetric information from different viewing angles, allowing comprehensive color assessment without requiring a complex multi-directional simultaneous detection system.
Solution Approach 2:
The system performs preliminary colorimetric detection at multiple angles before the vehicle component reaches the assembly line. By conducting measurements in advance at predetermined angle positions, the system identifies color mismatches early in the manufacturing process, enabling corrective actions before final assembly and avoiding rework at later stages.
2Loss of time
If colorimetric detection is performed earlier in the manufacturing process, then loss of time is reduced, but device complexity increases
Solution Approach 1:
A neural network model serves as an intermediary between the raw colorimetric data collected at multiple angles and the final color matching determination. The neural network processes the multi-angle measurements and outputs a probability value indicating color mismatch likelihood, simplifying the decision-making process and enabling early detection without requiring complex assembly line integration.
Solution Approach 2:
The patent replaces manual visual inspection with an automated colorimetric detection system using detectors and electronic controllers. This substitution of mechanical/human inspection with automated optical and computational systems enables earlier detection in the manufacturing process while managing complexity through standardized measurement protocols.
3Measurement precision
If multiple detectors are used to capture colorimetric information at different angles, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
Instead of using multiple detectors simultaneously, the system segments the detection process into sequential measurements at different angle positions. A single detector is positioned at each predetermined angle in turn, capturing colorimetric information that would otherwise require multiple simultaneous detectors, thereby reducing equipment costs while maintaining measurement precision.
Solution Approach 2:
The detection system employs periodic action by sequentially positioning the detector at different predetermined angles around the vehicle component. The detector moves to each angle position in a periodic sequence (e.g., 0°→45°→90°→135°), capturing complete colorimetric data through time-based sampling rather than spatial multiplicity, reducing hardware requirements.

AI summary
A colorimetric compliance control device includes a electronic communication device, a non-transitory computer readable medium, an electronic controller. The electronic communication device is programmed to electronically receive colorimetric information regarding a vehicle component. The non-transitory computer readable medium electronically stores a non-transitory computer learning model using the colorimetric information acquired by the detector as a first input. The non-transitory computer learning model generates a colorimetric value as an output value related to the colorimetric information. The electronic controller is programmed to compare the output value with a predetermined exemplary value. The electronic controller is programmed to determine when the output value deviates from the predetermined exemplary value.
