Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional liquid detection methods are used, then detection capability is provided, but the process is invasive and time-consuming
Solution Approach 1:
The patent replaces traditional mechanical or physical inspection methods with ultrasonic wavelength analysis. The ultrasonic sensor emits sound waves that travel through the liquid, and the processing subsystem analyzes the wavelength characteristics to identify liquid type without physical contact or invasive procedures, thereby reducing detection time while maintaining reliability
Solution Approach 2:
The patent changes the detection parameter from physical contact-based measurement to ultrasonic wavelength analysis. By measuring the wavelength of ultrasonic waves passing through the liquid, the system can rapidly identify liquid types without invasive procedures, solving the contradiction between detection capability and detection time
2Reliability
If traditional liquid detection methods are used, then detection capability is provided, but the process is invasive
Solution Approach 1:
The patent replaces invasive mechanical inspection with non-contact ultrasonic wavelength analysis. The ultrasonic sensor measures wavelength characteristics through the container wall or liquid surface without penetrating or contacting the liquid directly, eliminating the harmful invasive effect while maintaining detection capability
Solution Approach 2:
The patent uses the container wall or liquid surface as an intermediary medium. The ultrasonic waves pass through this intermediary to reach the liquid, allowing detection without direct contact with the liquid itself, thereby eliminating invasiveness while preserving detection capability
3Productivity
If rapid liquid detection is implemented, then time efficiency is improved, but detection accuracy may be compromised
Solution Approach 1:
The patent implements continuous ultrasonic wave transmission and real-time wavelength analysis. The processing subsystem continuously monitors the ultrasonic signal characteristics, enabling rapid detection while maintaining high accuracy through continuous data collection and analysis without interruption
Solution Approach 2:
The patent incorporates real-time feedback through the operator interface that displays detection results immediately. The system provides continuous feedback on the liquid type identification, allowing for rapid verification and adjustment, thereby maintaining both speed and accuracy in the detection process
