Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional station installation designing techniques, when performed in parallel for divided areas, often result in inefficient coverage due to overlapping cells formed by base stations at the boundaries of these areas, leading to suboptimal service area coverage.
Innovation Solution
A station installation designing assistance device that divides the service providing area into honeycomb-shaped small areas, allowing for parallel station installation designing while ensuring that base stations are strategically located to avoid overlapping cells by assigning unique small area numbers to non-adjacent areas, thus optimizing coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the service providing area is divided into multiple areas for parallel station installation designing, then the computational resources required are reduced, but the coverage efficiency deteriorates due to overlapping cells at area boundaries
Solution Approach 1:
The service providing area is divided into multiple divisional areas, and each divisional area is further divided into multiple small areas. This hierarchical segmentation allows parallel processing of station installation designing while reducing the scale of computation for each process. The small area division enables selective processing that avoids boundary overlap issues between divisional areas.
Solution Approach 2:
The patent applies different processing strategies to different regions: small areas at the boundaries of divisional areas are selectively excluded from parallel processing when they would cause overlap, while internal small areas are processed normally. This local differentiation maintains coverage efficiency by preventing overlapping cell formation at boundaries while preserving computational efficiency through parallel processing in non-boundary regions.
2Speed
If conventional parallel processing is applied to divided areas, then processing speed is improved, but station location selection accuracy deteriorates due to boundary overlap issues
Solution Approach 1:
By dividing the service providing area into smaller units (small areas) within each divisional area, the patent enables more precise control over which regions are processed in parallel. This segmentation allows the system to maintain high processing speed through parallel operations while improving station location selection accuracy by excluding boundary small areas that would cause overlap.
Solution Approach 2:
The patent changes the processing parameters by introducing small area division and selectively controlling parallel processing based on location (boundary vs. internal areas). This parameter change allows the system to optimize both processing speed and station location selection accuracy by adjusting which regions undergo parallel processing versus sequential processing.
