Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Administrators face inefficiency in determining prioritized parts for road infrastructure maintenance due to the large number of management units and repetitive work required to analyze temporal changes in road state indexes.
Innovation Solution
An infrastructure diagnostic device and method that displays time series of infrastructure states at multiple locations, allowing users to select and view associated locations on a map, facilitating efficient prioritization of maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If administrators repeatedly select and analyze each management unit individually to determine prioritized parts, then they can obtain detailed road state information, but the determination process becomes inefficient and time-consuming when managing large numbers of units
Solution Approach 1:
The patent combines multiple management unit data into a single aggregated view showing total deterioration values across all units. This allows administrators to quickly identify areas requiring attention without manually examining each unit individually, thus reducing time loss while maintaining access to detailed information when needed.
Solution Approach 2:
The system segments the analysis process into two levels: an aggregated overview level for quick assessment and a detailed unit level for in-depth analysis. Administrators can switch between these levels, obtaining detailed road state information only for selected units rather than analyzing all units in detail, thereby reducing overall determination time.
2Reliability
If administrators analyze all management units in detail to ensure comprehensive assessment, then accuracy of prioritization is improved, but the complexity and burden of repetitive work increases
Solution Approach 1:
The system implements partial action by allowing administrators to analyze only a subset of management units at any given time. The aggregated view provides sufficient information for most decisions, and detailed analysis is performed only when necessary, reducing operational complexity while maintaining prioritization accuracy for critical cases.
Solution Approach 2:
The aggregated deterioration value serves as an intermediary between the complete set of detailed unit data and the final prioritization decision. This intermediary provides a simplified representation that reduces operational complexity while preserving the essential information needed for accurate prioritization.
3Loss of information
If the system displays detailed time-series data for each management unit, then comprehensive road state monitoring is achieved, but the ease of operation decreases due to the large volume of information
Solution Approach 1:
The system extracts only the essential aggregated deterioration information from the complete set of detailed time-series data and presents it prominently. Full detailed data remains available but is not displayed by default, allowing comprehensive monitoring coverage while improving ease of operation through selective information extraction.
Solution Approach 2:
The system adds an aggregation dimension to the data presentation, transforming detailed unit-level time-series data into an aggregated overview. This dimensional transformation allows comprehensive monitoring of all units while maintaining ease of operation by presenting information in a condensed, manageable format.
