Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If extensive site investigation is conducted to construct an accurate positioning database, then location determination accuracy is improved, but time consumption and cost increase
Solution Approach 1:
The patent applies preliminary action by conducting site investigation and collecting positioning resource information in advance to construct a positioning database before actual location determination services are provided. This pre-collected database enables faster and more accurate location determination without requiring repeated site investigations, thus resolving the contradiction between accuracy and time consumption.
2Measurement precision
If extensive site investigation is conducted to construct an accurate positioning database, then location determination accuracy is improved, but cost increases
Solution Approach 1:
The patent performs site investigation and positioning resource collection in advance to build a comprehensive positioning database. This preliminary action eliminates the need for repeated investigations when providing location services, thereby reducing overall costs while maintaining high accuracy.
3Measurement precision
If positioning resource information is collected via site investigation, then positioning database accuracy is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent enables terminals to autonomously collect positioning resource information and perform location determination using the preconstructed positioning database. This self-service mechanism reduces the need for complex manual site investigation operations and simplifies the overall system while maintaining database accuracy.
4Reliability
If repetitive site investigations are performed to verify positioning performance, then service quality is improved, but productivity decreases
Solution Approach 1:
The patent conducts comprehensive site investigation and constructs the positioning database in advance before service deployment. This preliminary action eliminates the need for repeated verification investigations, thereby maintaining high service quality while significantly improving productivity and service provision efficiency.
