Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contact-based physiological measurement techniques are used, then measurement precision is improved, but user comfort and sleep quality deteriorate due to wearing tangible devices
Solution Approach 1:
The patent replaces contact-based mechanical sensing with non-contact radar detection technology. The radar system uses electromagnetic waves to detect physiological signals such as heartbeat and breathing without requiring physical contact with the user's body, thereby eliminating the discomfort of wearing sensors while maintaining measurement accuracy
Solution Approach 2:
The patent introduces radar technology as an intermediary between the measurement system and the user. Instead of direct contact between sensors and skin, the radar waves serve as an intermediary medium to transmit physiological information from the user's body to the detection system through obstacles like clothing and bedding
2Ease of operation
If non-contact detection methods are used, then user comfort is improved, but measurement precision deteriorates due to environmental interference and obstacles
Solution Approach 1:
The patent employs nanosecond pulse radar technology with specific frequency and pulse width parameters optimized for penetrating obstacles like clothing and bedding. By carefully selecting and adjusting the radar parameters (frequency, pulse duration, power), the system achieves accurate physiological detection through non-contact means while maintaining signal quality despite environmental interference
3Measurement precision
If advanced non-contact radar technology is used, then measurement precision is improved, but device cost increases making it unsuitable for home use
Solution Approach 1:
The patent integrates affordable radar modules and processing units into the mattress design, using cost-effective components that can be mass-produced. The system employs efficient signal processing algorithms that reduce the need for expensive hardware, making the overall solution economically viable for home use while maintaining accurate physiological monitoring capabilities
4Measurement precision
If contact-based monitoring devices are used, then measurement precision is improved, but ease of operation deteriorates due to the need for tight attachment to avoid environmental noise
Solution Approach 1:
The patent replaces the mechanical attachment system (wires, patches, tight bands) with a non-contact radar-based detection system. This eliminates the need for physical attachment to the user's body, allowing free movement and comfortable sleep positioning without compromising measurement accuracy, as the radar waves can detect physiological signals through obstacles without direct contact

AI summary
The present invention provides an intelligent bed mattress, which mainly uses a non-contact sensor to detect the physiological information of the human body. Through remote life information detection, it acquires the life information of the user by tracking the REM (rapid eye movement), monitoring the heartbeat, and detecting the breathing, and also captures and records the physiological information of the user by detecting time of leaving the bed and sleeping position. Through a control box, it can be connected with a mobile device or computer via Bluetooth pairing, and all of the captured information can be displayed or uploaded to a cloud database for storage. In this way, it can provide long-term measuring or real-time monitoring of the physiological information of the user, to facilitate the establishment of an accurate care modal.
