Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cameras are used for user positioning, then user position can be obtained, but the system requires many operational adjustments and training, and results may be inaccurate due to lighting changes
Solution Approach 1:
The patent replaces the optical camera-based positioning system with a pressure sensor-based detection system. Pressure sensors embedded in the floor or surface detect user presence and position through mechanical pressure, eliminating the need for complex camera adjustments, lighting considerations, and manual calibration. This substitution resolves the contradiction by providing automatic, accurate positioning without operational complexity.
2Reliability
If wireless signal transmitters are carried by users for tracking, then user position can be tracked, but users may forget to carry the device and tracking cannot be achieved
Solution Approach 1:
The system eliminates the need for users to actively participate in the tracking process by using pressure sensors that automatically detect user presence and position. The environment itself (floor, surfaces) becomes the sensing medium, providing passive, continuous tracking without requiring users to carry or operate any devices. This resolves the contradiction by making tracking reliable and convenient simultaneously.
3Extent of automation
If conventional service providing mechanisms are used, then services are provided according to user preferences, but services are not automatically provided based on user position
Solution Approach 1:
The patent implements a feedback loop where pressure sensors continuously monitor user position and presence, and this information automatically triggers appropriate services. The system processes pressure data to determine user location and state, then activates relevant services without manual intervention. This resolves the contradiction by enabling automatic service provision while maintaining accurate awareness of user position through continuous pressure sensor feedback.
