Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical float-based liquid level detection system is used, then the structure is simple and easy to manufacture, but the detection reliability is poor due to liquid surface stability issues
Solution Approach 1:
The patent replaces the mechanical float-based liquid level detection system with a non-contact liquid detection apparatus that uses optical or electromagnetic fields to detect liquid levels. This substitution eliminates the mechanical components that are sensitive to liquid surface instability, thereby improving detection reliability while reducing mechanical complexity.
Solution Approach 2:
The patent introduces a non-contact detection mechanism that acts as an intermediary between the liquid and the detection system. By using optical or electromagnetic fields as mediators, the system can detect liquid levels without direct mechanical contact, thus avoiding the problems caused by liquid surface instability.
2Reliability
If a non-contact liquid detection apparatus is used, then the liquid level detection reliability is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical float systems with non-contact optical or electromagnetic detection apparatus. While the non-contact technology itself is advanced, it eliminates the need for mechanical floats, linkages, and adjustment mechanisms, ultimately reducing overall system complexity while improving reliability.
3Ease of operation
If no visual display is provided, then the device structure is simple, but the user experience is poor due to lack of working state information
Solution Approach 1:
The patent incorporates a display device that provides visual feedback to users about the working state of the cleaning machine. The display shows information such as liquid level status, operational mode, and system alerts, enabling users to monitor and understand the device's state without adding significant structural complexity.
Solution Approach 2:
The patent utilizes color-coded visual indicators on the display to represent different working states and liquid levels. This approach provides intuitive user feedback through color changes, improving ease of operation while maintaining simple device structure.
