Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional wired sensors are used to monitor temperature and pH values, then measurement precision and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces wired mechanical connections with wireless NFC communication. The sensor system uses an NFC tag to wirelessly transmit temperature and pH data to receivers, eliminating the need for physical wiring while maintaining measurement capabilities. This substitution reduces device complexity and installation difficulty while preserving measurement precision through dedicated sensor components.
Solution Approach 2:
The NFC tag serves multiple functions: it stores sensor data, provides wireless communication, and enables energy transfer via electromagnetic induction. By integrating these functions into a single component, the system reduces overall device complexity while maintaining precise monitoring capabilities through the specialized sensors connected to the NFC tag.
2Reliability
If continuous monitoring of temperature and pH values is implemented, then solution safety and effectiveness are improved, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring instead of continuous monitoring. The NFC tag and sensors can be activated at intervals to read and transmit temperature and pH values, reducing energy consumption while still ensuring solution safety by checking critical parameters at regular intervals throughout storage and usage periods.
Solution Approach 2:
The NFC tag harvests energy from the electromagnetic field generated during NFC communication sessions. When a receiver communicates with the NFC tag, the electromagnetic induction process provides power to the sensors temporarily, allowing them to take measurements and transmit data without requiring an external power source or continuous energy supply.
3Ease of operation
If wireless NFC technology is used for data transmission, then ease of operation and device complexity are improved, but measurement precision and reliability may worsen
Solution Approach 1:
The patent replaces wired data transmission with wireless NFC communication, improving ease of operation by eliminating physical connections. The NFC technology provides reliable short-range wireless communication that maintains data accuracy through standardized protocols, while the specialized sensors ensure precise temperature and pH measurements are captured and transmitted accurately.
