Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations are installed in various locations through trial and error to find appropriate locations, then communication quality can be improved, but time and effort are significantly consumed
Solution Approach 1:
The system performs preliminary actions by calculating and determining optimal base station locations before actual installation. The control server computes appropriate locations based on terminal device distributions and shielding object information, allowing planners to avoid trial-and-error installations and directly deploy base stations at optimal positions, thereby reducing installation time while ensuring communication quality
Solution Approach 2:
A control server acts as an intermediary between terminal device location information and base station installation decisions. The control server receives location information from terminal devices, calculates optimal base station locations considering shielding objects, and provides installation recommendations, eliminating the need for manual trial-and-error installation processes
2Area of stationary object
If multiple base stations are installed without considering spatial environment, then coverage area increases, but resource utilization efficiency decreases
Solution Approach 1:
The system applies local quality by determining optimal base station locations based on local spatial environment characteristics. The control server analyzes terminal device distributions and shielding object information in different areas, calculating specific optimal locations for each region. This ensures base stations are placed where they can most effectively serve local terminal devices, maximizing resource utilization efficiency while achieving comprehensive coverage
Solution Approach 2:
The control server performs preliminary calculation of optimal base station locations before deployment. By pre-computing appropriate positions based on terminal distributions and environmental factors, the system ensures that base stations are installed at locations that maximize resource utilization efficiency from the outset, avoiding wasteful deployments while maintaining adequate coverage
3Productivity
If base stations are installed at appropriate locations according to spatial environment, then resource utilization efficiency improves, but installation complexity increases due to need for environmental analysis
Solution Approach 1:
The control server performs self-service by automatically calculating optimal base station locations based on received terminal device location information and shielding object data. The system independently processes the environmental analysis and generates installation recommendations without requiring complex manual environmental surveys, thereby improving resource utilization efficiency while keeping installation procedures relatively simple
Solution Approach 2:
The control server acts as an intermediary that handles the complex environmental analysis work. It receives basic location information from terminal devices, automatically processes shielding object data, calculates optimal base station locations, and provides installation recommendations. This intermediary approach simplifies the installation process for field personnel while ensuring scientifically determined optimal locations for high resource utilization efficiency
