Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a 5-angle color difference model is used to achieve accurate color difference quantification, then measurement precision is improved, but device complexity increases due to requiring 5 different measurement angles
Solution Approach 1:
The patent creates a computational model that replicates the 5-angle color difference calculation results using only 3-angle measurement data. The neural network is trained to copy the behavior and output of the full 5-angle system, allowing 3-angle devices to achieve 5-angle level accuracy without requiring the complex 5-angle measurement hardware
Solution Approach 2:
The patent transforms the measurement parameters by using 3-angle data (15°, 45°, 110°) to predict tolerance values that are then applied in the 5-angle color difference equation. This parameter transformation allows the system to work with fewer measurement angles while still producing accurate 5-angle equivalent results through mathematical compensation
2Ease of operation
If 3-angle color measurement systems are used to reduce device complexity, then ease of operation is improved, but measurement precision deteriorates due to inconsistent color difference values
Solution Approach 1:
The patent implements a feedback mechanism where the neural network continuously learns from training data to improve its predictions of 5-angle tolerance values from 3-angle measurements. The system uses feedback loops during training to adjust weights and biases, ensuring that the 3-angle system progressively achieves measurement precision consistent with the 5-angle standard
Solution Approach 2:
The patent introduces a neural network computational model as an intermediary between the 3-angle measurement system and the 5-angle color difference equation. This intermediary translates 3-angle data into predicted 5-angle tolerance values, bridging the gap between the simpler 3-angle system and the more accurate 5-angle standard
3Adaptability or versatility
If different manufacturers use different angle systems (3-angle vs 5-angle) to simplify their respective devices, then adaptability is improved, but loss of information occurs due to inconsistent color difference values
Solution Approach 1:
The patent creates a universal computational model that can process 3-angle measurement data from any manufacturer and produce consistent 5-angle equivalent results. This universal approach allows different manufacturers using different measurement systems to exchange and compare color data consistently, eliminating information loss while preserving each manufacturer's device flexibility
