Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite signal-based positioning technologies are used outdoors, then positioning accuracy is improved, but signal penetration through walls and roofs deteriorates
Solution Approach 1:
The patent introduces radio positioning support devices (intermediaries) that transmit radio signals to enable indoor positioning when satellite signals cannot penetrate walls and roofs. These devices act as mediators between the positioning system and the mobile device, allowing positioning functionality to be maintained indoors through local radio signal transmission rather than relying on penetrating satellite signals
2Area of stationary object
If radio positioning support devices are installed densely to improve coverage, then signal coverage is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent performs preliminary determination of optimal installation positions and areas for radio positioning support devices before actual installation. By using coverage models and systematic analysis to pre-identify where devices should be placed, the system achieves comprehensive coverage while minimizing the number of devices needed and simplifying the installation process
Solution Approach 2:
The patent determines specific installation positions and areas based on local coverage requirements and signal propagation characteristics. Rather than uniform dense deployment, the system identifies specific locations where devices provide maximum value, optimizing coverage while reducing overall device count and installation complexity
3Measurement precision
If manual installation positioning is used to ensure accurate placement, then positioning accuracy is improved, but installation time and labor cost increase
Solution Approach 1:
The patent pre-determines optimal installation positions and areas using coverage models and systematic analysis before actual device installation. This preliminary planning provides clear guidance for installers, eliminating the need for time-consuming manual trial-and-error positioning while ensuring devices are placed at optimal locations for maximum coverage effectiveness
Solution Approach 2:
The system uses automated coverage modeling and analysis to self-determine optimal installation positions without requiring expert manual intervention. The coverage models and determination algorithms perform the complex positioning calculations automatically, reducing reliance on skilled installers and significantly reducing installation time while maintaining high positioning accuracy
