Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If millimeter-wave radar detection devices are used to monitor reading distance, then eyesight protection is improved, but the devices cannot solve myopia caused by incorrect writing and reading postures and are limited to single application scenes
Solution Approach 1:
The patent integrates multiple detection functions into a single device: millimeter-wave radar for distance detection, accelerometer for posture detection, and gyroscope for orientation detection. This multi-functional design allows the device to address both reading distance issues and incorrect posture problems, while being applicable across multiple scenes including schools, family study rooms, and other environments.
2Measurement precision
If multiple detection circuits are integrated into the eyesight protection device, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection circuits (millimeter-wave radar detection circuit, accelerometer, gyroscope) and alarm circuits into a single integrated device with a unified control circuit. This merging approach maintains high detection accuracy through multiple sensors while reducing overall system complexity by using a centralized control architecture rather than separate independent systems.
Solution Approach 2:
The control circuit serves as an intermediary that receives data from multiple detection circuits (millimeter-wave radar, accelerometer, gyroscope), processes the information, and coordinates the alarm circuits. This intermediary component simplifies the system architecture by providing a central processing point that manages the complexity of multiple sensors without requiring complex direct connections between all components.
