Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contact-based monitoring methods are used, then measurement precision is improved, but ease of operation deteriorates due to direct contact requirements
Solution Approach 1:
The patent replaces mechanical contact-based sensing with electromagnetic wave-based radar sensing. The radar system uses radio waves to detect motion, respiration, and gestures without physical contact, thereby maintaining measurement precision while significantly improving ease of operation and user comfort.
Solution Approach 2:
The patent introduces electromagnetic waves as an intermediary between the monitoring system and the user. The radar apparatus transmits and receives radio waves that interact with the user's body movements, allowing indirect measurement of motion and respiration without direct contact, thus resolving the contradiction between accuracy and convenience.
2Ease of operation
If non-contact monitoring methods are used, then ease of operation is improved, but measurement precision deteriorates due to detection difficulties
Solution Approach 1:
The patent segments the monitoring functions into specialized radar capabilities: one for detecting gross motion, another for detecting respiration patterns, and a third for gesture recognition. This segmentation allows each function to be optimized independently, maintaining high measurement precision across different types of non-contact monitoring.
Solution Approach 2:
The patent employs dynamic signal processing techniques that adapt to different monitoring scenarios. The radar system dynamically adjusts its processing algorithms based on whether it is detecting motion, respiration, or gestures, thereby maintaining high measurement precision across various non-contact monitoring applications.
3Adaptability or versatility
If radar monitoring system is added, then functionality is improved for motion detection, but device complexity increases
Solution Approach 1:
The patent designs the radar apparatus to perform multiple functions: motion detection, respiration monitoring, and gesture recognition, all using the same hardware platform. This multi-functionality approach improves adaptability while controlling device complexity by avoiding the need for separate specialized sensors for each monitoring task.
Solution Approach 2:
The patent combines multiple monitoring capabilities into a single integrated radar system. By merging motion detection, respiration monitoring, and gesture recognition functions into one radar apparatus, the system achieves high versatility without proportionally increasing device complexity, as the same hardware infrastructure supports all functions.
