Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual planning of construction road routes is time-consuming and inefficient, requiring a week to a month of planning time and making it difficult for even experienced supervisors to design optimal routes.
Innovation Solution
A construction road route design device that acquires current and design topography data, identifies road ends, and uses a route searcher to calculate costs based on construction soil amounts, selecting a route that minimizes costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual planning is used for construction road routes, then experienced supervisors can design routes considering multiple factors, but the planning time required is very long (week to month)
Solution Approach 1:
The patent replaces the manual mechanical planning process with an automated computer-based system. The route searcher automatically calculates multiple candidate routes and evaluates them based on cost functions considering soil amounts, cutting/filling operations, and construction expenses, eliminating the need for manual supervisor analysis while maintaining or improving route design quality
Solution Approach 2:
The system performs self-evaluation of route candidates by automatically calculating costs and selecting optimal routes without human intervention. The route searcher independently evaluates multiple routes based on predefined cost criteria and selects the optimal route, enabling the system to serve itself in the route optimization process
2Adaptability or versatility
If manual planning is used for construction road routes, then supervisors can consider multiple design factors, but it is difficult to determine whether the designed route is optimal
Solution Approach 1:
The system provides feedback by calculating and comparing costs of multiple candidate routes. The route searcher evaluates each route based on comprehensive cost functions including soil amounts, cutting/filling operations, and construction expenses, then selects the optimal route with the lowest cost, providing clear verification of route optimality
Solution Approach 2:
The system changes the evaluation parameter from subjective supervisor judgment to objective quantitative cost calculation. By defining cost functions that incorporate soil amounts, cutting/filling volumes, and construction expenses, the system transforms the route evaluation into a measurable parameter-based selection process
3Productivity
If automated route search is implemented, then planning time is reduced, but the system must accurately calculate construction soil amounts from topography data
Solution Approach 1:
The system performs preliminary processing of topography data to create a searchable structure before route calculation. By pre-processing the current and design topography data into a format suitable for automated analysis, the system enables efficient route searching while maintaining accurate soil amount calculations through structured data representation

AI summary
The construction road route design device (1) includes: a current topography data acquirer (21) to acquire topography data indicating a current topography of a construction site; a design topography data acquirer (22) to acquire topography data indicating a design topography of a construction site; a road end acquirer (23) to acquire a plurality of two or more road ends that serves as a start point and an end point of a construction road; and a route searcher to search for a route between the plurality of road ends. The route searcher (25) selects nodes existing between the plurality of road ends, calculates, for a plurality of routes going through the selected nodes and leading to the plurality of road ends, costs based on construction soil amounts of the construction road from topography data of the current topography and the design topography, and selects a route that minimizes a calculated cost.
