Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If infrared temperature screening is used for fever detection, then temperature measurement can be obtained, but the measurement consistency is poor and requires verification
Solution Approach 1:
The patent combines multiple temperature sensors (first temperature sensor and second temperature sensor) within a single sensor assembly to perform simultaneous temperature measurements. By merging multiple sensing elements, the system obtains multiple temperature readings that can be processed to determine a final temperature measurement, thereby improving measurement consistency and reducing the need for repeated verification
Solution Approach 2:
The system processes temperature measurements from multiple sensors and uses this information to determine an accurate temperature reading. The feedback mechanism allows the system to evaluate multiple measurements and derive a reliable temperature value, improving measurement precision without requiring external verification
2Object-affected harmful factors
If contactless temperature screening is implemented, then viral spread can be prevented, but measurement accuracy may be compromised
Solution Approach 1:
The patent combines multiple temperature sensors in a single assembly to perform contactless temperature measurements. By integrating multiple sensing elements that can simultaneously measure temperature without contact, the system maintains both the safety benefit of contactless measurement and improves accuracy through multiple data points
Solution Approach 2:
The sensor assembly acts as an intermediary device that enables non-contact temperature measurement. The multiple sensors within the assembly work together to capture temperature data through radiation or other non-contact methods, maintaining safety while improving measurement reliability through redundant sensing
3Quantity of substance
If multiple temperature sensors are deployed in a network, then coverage is improved, but signal interference increases
Solution Approach 1:
The patent segments the communication function by introducing a base station that centralizes data collection from multiple sensor assemblies. Each sensor assembly communicates with the base station independently, and the base station processes all temperature measurements. This segmentation prevents direct interference between sensor signals while maintaining network-wide coverage
Solution Approach 2:
The base station serves as an intermediary that receives temperature measurements from multiple sensor assemblies and processes the data centrally. This intermediary approach allows multiple sensors to operate in the network without their signals interfering with each other, as all communications are routed through the base station which manages the data aggregation and processing
