Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mercury meter is used for body temperature detection, then the device is simple and reliable, but the output speed is slow
Solution Approach 1:
The patent replaces the mechanical mercury meter system with an electronic detection system comprising a temperature detection module, charging module, timing module, and processing module. This substitution eliminates the slow mechanical response of mercury meters while maintaining detection reliability through electronic signal processing and timing-based temperature determination.
2Speed
If an electronic probe is used for body temperature detection, then the output speed is fast, but the precision is low
Solution Approach 1:
The patent implements a feedback mechanism where the timing module continuously monitors the charging rate of the charging module, and the processing module adjusts the temperature determination based on the detected charging rate. This feedback loop ensures high precision by dynamically correcting for variations in charging characteristics, while maintaining fast output speed through electronic processing.
Solution Approach 2:
The patent replaces the simple electronic probe with a sophisticated electronic detection system that uses timing-based measurement and charging rate analysis. This substitution provides both fast electronic response and high precision through multiple processing stages including voltage detection, timing measurement, and temperature calculation.
3Productivity
If a fast-response temperature detection system is implemented, then the output speed is high, but the precision cannot be guaranteed
Solution Approach 1:
The patent uses feedback from the timing module that detects the charging rate to continuously adjust and refine the temperature measurement. The processing module receives both the timing information and charging rate data, using this feedback to calculate an accurate temperature value that maintains precision even with fast response times.
Solution Approach 2:
The patent introduces the charging module as an intermediary between the temperature detection module and the timing module. This intermediary converts temperature variations into charging rate variations, which are then measured by the timing module. This intermediary mechanism enables both fast response and high precision by providing a measurable parameter that reflects temperature accurately.
