Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional non-invasive methods are used to measure core body temperature, then the measurement process is simple, but the accuracy and continuity of temperature monitoring is insufficient
Solution Approach 1:
The monitoring system is segmented into two distinct components: a disposable patch device containing temperature sensors and an electronic module for data processing. This segmentation allows the complex electronic processing functions to be isolated in a reusable module while the patch remains simple and disposable, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent introduces an intermediary processing layer that includes calibration algorithms and correction factors. This intermediary layer processes raw sensor data to compensate for environmental influences and sensor drift, significantly improving measurement accuracy without requiring direct modification of the sensor hardware itself.
2Reliability
If continuous core body temperature monitoring is implemented, then patient safety and thermal regulation are improved, but the complexity of the monitoring system increases
Solution Approach 1:
The system implements dynamic monitoring with adjustable sampling rates and adaptive alert thresholds. The electronic module can dynamically adjust monitoring intensity based on patient condition, providing continuous surveillance when needed while reducing complexity during stable periods. This dynamic approach maintains high reliability without requiring permanently complex system architecture.
Solution Approach 2:
The patch device is designed as a disposable, low-cost component that can be replaced periodically. This allows continuous monitoring to be achieved through simple replacement of inexpensive patches rather than maintaining complex continuous-calibration systems, thereby improving reliability through fresh sensors while keeping overall system complexity manageable.
3Measurement precision
If multiple temperature sensors are used to improve measurement accuracy, then temperature detection precision is enhanced, but the device complexity and data processing requirements increase
Solution Approach 1:
Multiple temperature sensors are merged into a single integrated reading through the electronic module's processing algorithms. The system combines data from multiple sensors and applies correction factors to produce a single accurate core body temperature value, achieving enhanced precision while maintaining simple device architecture through functional integration rather than physical complexity.
