Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual inspection is used for chemical detection, then the method is simple and requires minimal equipment, but the detection is subjective and limited by lighting conditions
Solution Approach 1:
The patent uses a mobile device camera to create an optical copy (image) of the chemical test result instead of relying on direct visual inspection. This copy can be captured, stored, and analyzed objectively, resolving the contradiction between simple operation and objective measurement.
Solution Approach 2:
The patent replaces the mechanical/visual inspection process with an optical-digital system. The camera captures light reflected from the test sample, converting a subjective visual assessment into an objective digital image that can be analyzed by software algorithms.
2Device complexity
If visual inspection is used for chemical detection, then no additional equipment is needed, but sensitivity and detection accuracy are limited
Solution Approach 1:
The patent leverages the multi-functionality of mobile devices, which already have cameras and processing capabilities. Instead of adding specialized detection equipment, the system uses the existing camera to capture chemical test results, achieving enhanced sensitivity without increasing device complexity.
Solution Approach 2:
By creating a digital copy of the test sample through the camera, the system enables enhanced image processing and analysis that improves detection sensitivity while using the same simple camera hardware, thus resolving the contradiction between equipment simplicity and detection accuracy.
3Speed
If field-deployable solutions are implemented for on-site analysis, then rapid detection is achieved, but efficient analysis of multiple samples is difficult
Solution Approach 1:
The patent implements feedback through automated image analysis software that processes captured images, compares them against reference data, and provides immediate results. This feedback mechanism enables rapid and efficient analysis of multiple samples by automating the evaluation process.
Solution Approach 2:
The system enables self-service through automated image processing and analysis capabilities built into the mobile device. The software automatically processes images, identifies chemical substances, and manages sample records without requiring manual intervention, thereby improving productivity in field deployment.
4Measurement precision
If objective image processing is used instead of visual inspection, then detection accuracy is improved, but data management and documentation become more complex
Solution Approach 1:
The patent implements self-service through automated image processing software that handles data management, storage, and documentation automatically. The system manages multiple samples and their corresponding images without requiring manual data entry or organization, thus improving accuracy while avoiding increased complexity.
