Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the number of temperature-sensitive diodes is increased to improve measurement range, then the output signal level increases, but the accuracy of temperature determination decreases when the number does not match pre-stored information
Solution Approach 1:
The patent applies dynamics by making the microcomputer's processing capability adaptive rather than fixed. The system dynamically adjusts its temperature determination algorithm based on the actual number of connected temperature-sensitive diodes, allowing the measurement system to adapt to different configurations while maintaining accuracy across the extended measurement range.
Solution Approach 2:
The patent changes the parameter of the determination algorithm based on the detected number of sensing devices. By modifying the calculation parameters according to the actual configuration, the system resolves the contradiction between extended measurement range (achieved through multiple diodes) and measurement precision (requiring accurate calibration for specific configurations).
2Measurement precision
If the microcomputer is designed to match a specific number of temperature-sensitive diodes, then temperature determination accuracy is maintained, but the adaptability to different configurations is reduced
Solution Approach 1:
The patent implements universality by designing the microcomputer to handle multiple configurations of temperature-sensitive diodes through a single adaptive algorithm. The system can universally process different numbers of sensing devices (from 1 to 10 or more) by detecting the actual count and adjusting its determination method accordingly, eliminating the need for multiple specialized designs.
Solution Approach 2:
The patent applies preliminary action by having the system detect and count the number of connected temperature-sensitive diodes before performing temperature determination. This preliminary detection allows the microcomputer to pre-adjust its algorithm parameters to match the actual configuration, ensuring accuracy is maintained regardless of the specific number of devices connected.
3Device complexity
If the system does not pre-store information about the number of temperature-sensitive diodes, then device complexity is reduced, but measurement accuracy decreases
Solution Approach 1:
The patent applies self-service by enabling the microcomputer to automatically detect the number of connected temperature-sensitive diodes and autonomously adjust its determination algorithm. Instead of requiring pre-stored configuration information or external setup, the system self-configures based on the actual hardware present, maintaining accuracy without increasing complexity.
Solution Approach 2:
The patent implements feedback by having the system continuously monitor the output signals from the temperature-sensitive diodes and use this feedback to determine the actual number of connected devices. The microcomputer then uses this feedback information to adjust its determination algorithm in real-time, ensuring accuracy without requiring pre-stored configuration data.
