Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-contact infrared thermometers are used to avoid cross infection and eliminate safety risks, then safety and hygiene are improved, but the display screen becomes relatively small and operation becomes complex
Solution Approach 1:
The patent integrates multiple functions into a single device: temperature measurement, object identification via camera, data storage in address book, and temperature history management. This allows the device to serve as both a thermometer and a data management system, reducing the need for separate devices and simplifying user interaction through unified operation.
Solution Approach 2:
The device automatically identifies objects using camera imaging, retrieves stored temperature algorithms based on object type, and performs temperature corrections without requiring manual selection or complex user input. This automation reduces operational complexity while maintaining safety features.
2Measurement precision
If contact temperature measurement devices are used, then temperature measurement can be performed, but measurement speed is low and portability is poor
Solution Approach 1:
The patent replaces contact-based mechanical temperature measurement with non-contact infrared temperature sensing. The temperature sensor detects infrared radiation from the object's surface to determine temperature without physical contact, significantly improving measurement speed and portability while maintaining measurement capability.
3Measurement precision
If different temperature algorithms are matched for different measured objects, then temperature measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The device uses camera imaging to identify the object type and provides feedback to select the appropriate temperature algorithm automatically. This feedback mechanism ensures accurate temperature measurement for different objects (human body, animal, inanimate objects) without requiring users to manually choose algorithms, thereby improving accuracy while managing complexity through automated decision-making.
Solution Approach 2:
The system changes measurement parameters (temperature algorithms and correction factors) based on the identified object type. Different objects have different thermal properties, so the device adjusts its measurement parameters dynamically to optimize accuracy for each specific measurement scenario.
