Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional measurement techniques (mechanical probes, electrical impedance, ultrasound) are used to monitor biofilm formation, then material erosion can be detected, but these methods are invasive, complex, or fail to provide accurate real-time data
Solution Approach 1:
The patent replaces mechanical probes, electrical impedance measurements, and ultrasound techniques with optical detection methods. Specifically, it uses changes in light transmission or reflection properties to detect biofilm formation, thereby eliminating the complexity and invasiveness of mechanical and electrical measurement systems while maintaining or improving measurement accuracy.
Solution Approach 2:
The patent introduces light as an intermediary medium to detect biofilm formation indirectly through changes in optical properties (transmission, reflection, absorption) rather than directly measuring physical or electrical properties of the biofilm. This intermediary approach simplifies the measurement system while providing accurate real-time data.
2Reliability
If invasive measurement techniques are used to monitor biofilm, then material erosion can be detected, but the techniques damage the test environment and provide only limited data
Solution Approach 1:
The patent replaces invasive mechanical and electrical measurement techniques with non-invasive optical detection methods. Light interacts with the biofilm and test environment without causing physical damage, thereby maintaining environmental integrity while providing reliable real-time data on biofilm formation and material erosion.
Solution Approach 2:
The patent uses optical signals to create information copies of the biofilm formation process without physically interacting with or damaging the test environment. By measuring changes in light properties (intensity, wavelength, polarization) as they pass through or reflect from the environment, the system obtains reliable data while leaving the test environment undisturbed.
3Productivity
If conventional monitoring methods are used, then some erosion data can be obtained, but real-time monitoring of biofilm formation and material erosion is not achieved
Solution Approach 1:
The patent implements continuous real-time monitoring by continuously transmitting light through or reflecting from the test environment and continuously detecting changes in optical properties. This continuous optical measurement process enables real-time detection of biofilm formation and material erosion without interruption or delay, significantly improving monitoring efficiency compared to conventional periodic sampling methods.
