Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional chemical analysis methods are used, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates a visual copy of the chemical sample's evaporation pattern and analyzes this image representation instead of the physical sample itself. By capturing the dried deposit pattern as an image and analyzing its morphological features, the system replaces complex physical/chemical analysis equipment with simple imaging devices while maintaining identification accuracy through pattern recognition
Solution Approach 2:
The patent replaces mechanical/physical chemical analysis systems with an optical imaging system. Instead of using complex analytical instruments to detect chemical composition, the system uses image capture and computer vision algorithms to analyze the visual patterns left after evaporation, substituting physical measurement mechanisms with optical detection and computational analysis
2Measurement precision
If conventional chemical analysis methods are used, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent performs the evaporation process as a preliminary step that naturally occurs before analysis. By allowing the sample to evaporate and form its characteristic deposit pattern first, the system prepares the sample in a state that is immediately suitable for rapid image capture and analysis, eliminating the need for time-consuming preparation steps in traditional methods
Solution Approach 2:
The patent creates a visual copy of the chemical sample's evaporation pattern and analyzes this image representation instead of the physical sample itself. By capturing the dried deposit pattern as an image and analyzing its morphological features, the system replaces complex physical/chemical analysis equipment with simple imaging devices while maintaining identification accuracy through pattern recognition
3Measurement precision
If conventional chemical analysis methods are used, then measurement precision is improved, but ease of operation worsens
Solution Approach 1:
