Moving Means Determination Device Using Scoring Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving route determination techniques fail to accurately determine a user's route when adjacent different routes are present, leading to inaccuracies in route identification.
Innovation Solution
A moving means determination device that includes a determination information storage unit, a log acquisition unit, and a moving means determination unit, which uses monitoring position identification information and position management logs to accurately determine the user's moving route by employing a scoring table and learning model for data processing reduction and improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position management logs are analyzed to determine moving routes, then route determination can be performed, but accuracy deteriorates when adjacent different routes are present
Solution Approach 1:
The system pre-calculates and stores determination information including scores for multiple possible routes before actual route determination is needed. When a user's position log is analyzed, the pre-computed scores for adjacent routes are already available, enabling rapid and accurate comparison to determine the most likely route without real-time computational delays or errors
Solution Approach 2:
The system introduces scoring parameters and determination information that quantify the likelihood of each route. By transforming the route determination problem into a parameter-based scoring system, the system can objectively compare adjacent routes using numerical scores rather than ambiguous position matching, thereby improving accuracy when multiple routes are nearby
2Measurement precision
If comprehensive position data is processed to improve determination accuracy, then route accuracy improves, but data processing amount increases
Solution Approach 1:
The system extracts only the essential determination information (scores and route identifiers) from comprehensive position data and stores them in a condensed format. When determining routes, only this extracted determination information is processed rather than analyzing entire position logs, significantly reducing data processing requirements while maintaining accuracy
Solution Approach 2:
By pre-processing position data to extract and store determination information in advance, the system avoids the need to process comprehensive position data during actual route determination. This preliminary extraction reduces the data processing burden during operation while preserving the accuracy benefits of comprehensive analysis
