Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional surfactant concentration measurement methods are used, then measurement accuracy can be achieved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical measurement instruments with a mobile device-based imaging system. A camera captures images of the surfactant solution, and image processing algorithms analyze the visual characteristics to determine surfactant concentration. This substitution of mechanical measurement systems with optical-digital systems resolves the contradiction by achieving accurate measurements through software-based image analysis rather than complex hardware instruments.
Solution Approach 2:
The patent creates a digital copy (image) of the surfactant solution and analyzes this copy to determine concentration. Instead of directly measuring the solution with complex instruments, the system captures an optical copy via camera and processes it computationally. This copying approach enables accurate measurement while keeping the physical device simple and accessible.
2Reliability
If precise surfactant concentration measurement is implemented, then cleaning effectiveness improves, but operational complexity increases
Solution Approach 1:
The measurement system is designed to be self-service through automated image capture and processing. The mobile device automatically captures the image of the surfactant solution and the embedded algorithms automatically analyze it to provide concentration results. This automation eliminates the need for complex manual operations or specialized operator skills, making the reliable measurement process simple and accessible to any user.
Solution Approach 2:
The patent utilizes visual characteristics (color, intensity, patterns) of the surfactant solution that naturally change with concentration. By detecting these inherent visual changes rather than requiring complex operational procedures, the system achieves reliable measurements while maintaining ease of operation. The user simply needs to capture an image, and the algorithm detects the concentration-based visual variations.
3Ease of manufacture
If manual surfactant concentration monitoring is performed, then cost savings on equipment can be achieved, but measurement precision decreases
Solution Approach 1:
The patent leverages the universality of mobile devices that already exist in most settings. The same mobile device used for communication and other purposes is utilized for surfactant concentration measurement. This multi-functionality approach eliminates the need for dedicated expensive measurement equipment while maintaining measurement precision through sophisticated image processing algorithms running on the universal mobile platform.
