Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement is used to obtain base station coordinates, then positioning precision can be achieved, but engineering cost increases and mobility requirements cannot be met
Solution Approach 1:
The patent replaces manual mechanical measurement with an automated system using mobile base stations equipped with GPS modules and ultra-wideband communication modules. The system automatically obtains coordinates through GPS positioning and calculates base station coordinates through triangulation algorithms, eliminating the need for manual measurement while maintaining precision and reducing engineering cost.
Solution Approach 2:
The mobile base station performs self-positioning using its GPS module to obtain its own coordinates, then uses ultra-wideband communication to measure distances to other base stations. Through automated triangulation calculations, the system determines the coordinates of all base stations without external assistance, achieving self-service operation.
2Measurement precision
If manual measurement is used to obtain base station coordinates, then positioning precision can be achieved, but time consumption increases due to difficulty in measuring multiple base stations in large indoor spaces
Solution Approach 1:
The patent employs a mobile base station that can dynamically move to different positions within the indoor space. The mobile base station automatically navigates to predetermined positions, performs measurements, and collects data from multiple locations. This dynamic approach enables rapid coordination of multiple base stations without the time-consuming manual measurement process, achieving both precision and efficiency.
3Ease of operation
If GPS signals are used for indoor positioning, then positioning can be performed, but centimeter-level precision cannot be achieved due to limited signal availability
Solution Approach 1:
The patent merges GPS positioning with ultra-wideband communication technology. The mobile base station uses GPS to obtain its own coordinates and then combines this with ultra-wideband distance measurements to other base stations. By integrating these two technologies, the system achieves centimeter-level precision indoors while maintaining the ease of operation provided by GPS availability.
Solution Approach 2:
The mobile base station acts as an intermediary between GPS satellite signals and the indoor positioning targets. It receives GPS signals outdoors, obtains precise coordinates, then uses ultra-wideband communication to transfer this positioning capability indoors by measuring distances to fixed base stations, thereby extending GPS-level precision to indoor environments.
