Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of potential radio sites are considered to ensure coverage and performance, then the reliability of identifying optimal sites improves, but the device complexity and computational requirements increase significantly
Solution Approach 1:
The patent segments the large set of potential radio sites into smaller manageable groups based on geographic regions, terrain characteristics, and infrastructure availability. The search tool processes these segmented groups separately, evaluating radio path profiles for each segment and combining results to identify optimal sites. This segmentation reduces computational complexity while maintaining comprehensive coverage and selection accuracy.
2Measurement precision
If comprehensive analysis of all potential sites is performed to meet design objectives, then the measurement precision of radio path evaluation improves, but the loss of time and computational resources increases
Solution Approach 1:
The patent performs preliminary filtering and pre-analysis of potential radio sites before conducting full radio path profile evaluations. The search tool first identifies sites that meet basic criteria such as geographic location, terrain suitability, and infrastructure availability. Only sites passing this preliminary screening undergo detailed radio path analysis, significantly reducing the number of full evaluations required while maintaining measurement precision for candidate sites.
Solution Approach 2:
The patent implements a multi-stage evaluation process where sites are assessed at different levels of detail. Initial screening uses simplified models and partial analysis, while only the most promising candidates receive exhaustive radio path profile evaluations. This partial action approach ensures high measurement precision for final site selections while avoiding the time cost of applying full analysis to all potential sites.
3Reliability
If multiple permutations of radio sites are evaluated to optimize link performance, then the reliability of meeting design goals improves, but the productivity of the site selection process decreases
Solution Approach 1:
The patent implements a dynamic search process that adapts the evaluation depth and scope based on intermediate results. The search tool adjusts which site permutations require full analysis versus simplified evaluation, and dynamically prioritizes promising path combinations. This dynamic approach maintains high reliability in identifying configurations that meet design goals while improving productivity by avoiding exhaustive evaluation of all possible permutations.
Data Source
AI summary
A microwave path search tool for finding radio path trails between a source site at a first geographic location and a target site at a second geographic location, wherein radio paths constituting a radio path trail meet certain radio link design goals subject to certain design constraints. The tool receives information relating to the source and target sites and sites within a buffer region around the source and target sites. The tool also receives path profile computation information such as data representing the terrain and clutter in the buffer region. The tool uses this information to analyze potential radio paths and identify radio paths forming a radio link between the source and target sites that best meets the radio link design goals. The tool can also perform pre-run analysis and use incrementally increasing linear or segmented expansions of search areas within the buffer region to facilitate the radio path search.
