Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the temperature sensor is continuously activated to measure object temperature, then the temperature measurement availability is improved, but the power consumption increases
Solution Approach 1:
The temperature sensor is activated periodically based on detected gestures rather than continuously. The system uses gesture detection triggers to activate the temperature sensor only when needed, implementing a periodic action pattern that reduces power consumption while maintaining measurement availability when users actually need temperature data.
Solution Approach 2:
The system uses the inertial sensor to automatically detect gestures and trigger temperature measurement without requiring manual user input. The device serves itself by using motion detection data to intelligently activate the temperature sensor, eliminating the need for continuous monitoring or manual activation by the user.
2Adaptability or versatility
If multiple sensors are disposed in a narrow internal space to provide comprehensive functionality, then the device versatility is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensor functions (temperature sensing and motion/gesture sensing) into a single wearable device housing. By merging these sensor capabilities together and coordinating them through a unified control system, the device achieves comprehensive functionality while managing the complexity through integrated design rather than separate independent systems.
Solution Approach 2:
The wearable device is designed with multi-functional capabilities by incorporating both temperature measurement and gesture detection functions. The inertial sensor serves multiple purposes including gesture recognition and potentially motion tracking, while the temperature sensor provides health monitoring capabilities, making the device universally applicable for various health and interaction scenarios.

Function Achieved in This Case
Enables convenient and power-efficient temperature measurement of objects by activating the temperature sensor only when necessary, improving battery efficiency and user convenience.
Implementation Method 1
The temperature sensor may acquire radiant rays (radiation) (e.g., electromagnetic waves, radio waves, or infrared energy emitted from the object) based on infrared rays (IRs) generated (e.g., emitted) from a surface of the object, and the temperature sensor may measure the temperature of the object on the basis of the acquired radiant rays.
