Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact-based liquid level sensing is used, then the sensor can directly detect liquid presence, but it cannot be used with toxic substances or in scenarios where liquid contact is unsafe
Solution Approach 1:
The patent introduces a non-contact sensor as an intermediary device that detects liquid levels through the container wall using electromagnetic fields, eliminating the need for direct contact between the sensor and liquid. This allows safe monitoring of toxic substances while maintaining detection accuracy.
Solution Approach 2:
The patent replaces mechanical contact-based sensing with electromagnetic field-based sensing. The sensor uses electromagnetic induction to detect liquid levels through the container wall, substituting physical contact with field interaction, thereby enabling use with toxic substances and various container materials.
2Adaptability or versatility
If non-contact sensing is used, then safety with toxic substances is improved, but sensing functionality and accuracy may be reduced
Solution Approach 1:
The patent designs a universal sensor system that can detect different liquid levels through various non-metallic container materials by adjusting sensing parameters and algorithms. The sensor maintains high measurement precision across different scenarios while ensuring safety with toxic substances.
Solution Approach 2:
The patent employs parameter adjustment and calibration techniques to optimize the electromagnetic sensing characteristics for different container materials and liquid types. By changing sensing parameters and using advanced algorithms, the system maintains high detection accuracy while operating in non-contact mode for safety.
3Device complexity
If simple sensing mechanisms are used, then device complexity is reduced, but functionality and intelligence are limited
Solution Approach 1:
The patent incorporates a learning function that performs preliminary actions by automatically calibrating and adapting to the specific container and liquid combination during initial use. This intelligent adaptation enhances versatility without requiring complex manual configuration or increasing overall device complexity.
