Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a real sensor is pre-positioned and actual measurement data is used for configuration, then positioning accuracy can be achieved, but the process requires high technical expertise and near-perfect visualization skills
Solution Approach 1:
The patent creates a virtual copy (digital twin) of the real sensor that replicates all physical and technical properties. This virtual sensor can be positioned and configured in the augmented reality environment without requiring the real sensor to be physically installed, thereby eliminating the need for pre-positioning while maintaining positioning accuracy through the virtual model.
Solution Approach 2:
The augmented reality system acts as an intermediary between the user and the sensor positioning process. It overlays virtual sensor representations and measurement data visualizations onto the real-world view, providing intuitive spatial feedback that eliminates the need for near-perfect visualization skills while maintaining precise positioning capability.
2Loss of information
If a real sensor is pre-positioned and connected, then actual measurement data can be obtained, but it remains unclear whether the sensor is installed in a suitable location with sufficient detection range
Solution Approach 1:
The system performs preliminary positioning and assessment using virtual sensors before the real sensor is physically installed. The augmented reality environment allows users to test different positions and configurations virtually, visualizing detection ranges and coverage areas, thereby determining suitable installation locations before actual hardware deployment.
Solution Approach 2:
By using a virtual copy of the sensor with identical detection characteristics, the system can simulate and visualize the sensor's detection range and coverage in the actual environment before physical installation, enabling assessment of installation suitability without requiring the real sensor to be in place.
3Reliability
If multiple sensors are positioned and configured, then comprehensive safety coverage can be achieved, but the complexity of coordination and optimization increases
Solution Approach 1:
The patent merges multiple virtual sensor representations into a single augmented reality visualization environment. The system simultaneously displays and coordinates multiple sensors' positions, detection ranges, and coverage areas, allowing intuitive optimization of sensor networks to achieve comprehensive safety coverage while reducing coordination complexity through unified visual feedback.
