Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional analytical methods are used for fluid identification and authentication, then measurement precision and reliability are improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent uses digital images as a copy or representation of the fluid's optical properties instead of requiring direct physical or chemical analysis. By capturing images under controlled lighting conditions and analyzing color space characteristics (HSV, LAB, RGB), the system creates a digital replica of the fluid's identity that can be compared against reference databases, achieving accurate fluid identification without complex analytical equipment
Solution Approach 2:
The patent replaces complex mechanical and chemical analytical systems with an optical-digital system. Instead of using sophisticated instruments for fluid analysis, the invention substitutes a smartphone camera, controlled light sources, and image processing algorithms to perform fluid identification and authentication, dramatically simplifying the device while maintaining measurement precision
2Reliability
If conventional analytical methods are used for fluid authentication, then reliability is improved, but cost increases significantly
Solution Approach 1:
The patent employs inexpensive, readily available components such as smartphone cameras, LED light sources, and standard image processing software instead of costly specialized equipment. The system uses disposable or low-cost elements like colored filters and reference fluid samples to create a reliable authentication mechanism that is accessible to small businesses and individual users
Solution Approach 2:
The patent creates a multi-functional system where a single device (smartphone) performs multiple functions: capturing fluid images, analyzing color characteristics, comparing against references, and providing authentication results. This universal approach eliminates the need for separate specialized equipment for each analytical task, reducing overall system cost while maintaining reliability
3Measurement precision
If detailed fluid analysis is performed using conventional methods, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements automated image capture and analysis where the system itself performs the complex tasks of lighting control, image acquisition, color space conversion, and characteristic extraction. The user simply needs to place the fluid sample and press a button, while the system automatically processes the images through multiple color spaces (HSV, LAB, RGB) and compares results against reference databases, delivering precise fluid characterization without requiring user expertise in image analysis
