Engineering Contradiction Analysis
1Measurement precision
If traditional triangulation positioning method is used to calculate distance between two objects, then positioning accuracy can be achieved, but calculation process becomes cumbersome and time-consuming
Solution Approach 1:
The positioning system segments the calculation process by having multiple receivers independently calculate their distances to the main device and device of interest separately. Each receiver computes its own distance data based on signal transmission time, then the calculation module aggregates these segmented distance results to determine relative positions, avoiding the need for complex six-coordinate calculations
Solution Approach 2:
The system performs preliminary action by pre-establishing the positions of multiple receivers in the space and having them continuously broadcast positioning signals. When positioning is needed, the distance calculations are already prepared through signal transmission time measurements, enabling rapid relative position determination without time-consuming coordinate computations
2Loss of information
If traditional positioning calculation method is used, then complete coordinate information can be obtained, but real-time tracking of moving objects becomes impractical
Solution Approach 1:
The system replaces the mechanical coordinate calculation method with a signal-based distance measurement approach. Instead of computing six coordinates through complex mathematical operations, the system uses signal transmission time to directly obtain distance information, which is then used to determine relative positions. This substitution enables real-time tracking of moving objects while maintaining complete positioning information
Solution Approach 2:
Each receiver independently performs distance calculation to the main device and device of interest using the signal transmission time from the main device. The receivers self-generate their distance data without requiring centralized coordinate computation, enabling parallel processing and real-time tracking capability
