Construction Machine Route Guidance for Steep Gradient Terrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route guidance technologies for construction machines fail to provide a viable path when the machine must traverse slopes with gradients exceeding a predetermined threshold, preventing it from reaching its destination.
Innovation Solution
A traveling route guidance device that acquires three-dimensional landform information, determines the machine's current and destination positions, and derives routes within a permissible gradient range, outputting either a preparation-unrequired route if available or identifying necessary preparations to ensure the machine stays within the stable gradient range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle avoids slopes with gradient exceeding a predetermined threshold, then the vehicle stability is improved, but the vehicle cannot reach the destination when no such route exists
Solution Approach 1:
The system performs preliminary analysis of the landform and identifies locations requiring preparation before route selection. By预先 determining which slopes need grading or earthwork, the system enables routes that would otherwise be impassable, allowing the vehicle to reach destinations while maintaining stability through advance landform modification.
Solution Approach 2:
The system introduces an intermediary element - the landform preparation information - between the vehicle and the steep slope. By identifying and communicating specific preparation requirements for intermediate locations, the system enables the vehicle to safely traverse slopes that would normally be prohibited, thus resolving the contradiction between stability and route availability.
2Adaptability or versatility
If the vehicle traverses slopes exceeding the permissible gradient range, then the destination becomes reachable, but the vehicle stability deteriorates
Solution Approach 1:
The system applies local quality by providing specific gradient information for specific locations along the route. Rather than uniformly avoiding all steep slopes, the system identifies particular segments where gradients exceed the permissible range and provides targeted preparation information for those specific locations, enabling selective route usage based on local landform conditions.
Solution Approach 2:
The system changes the parameter presentation by providing detailed gradient information for specific landform locations. By transforming the route information to include specific gradient parameters and preparation requirements, the system enables the vehicle to understand and prepare for slope conditions, thus safely traversing routes that would otherwise be prohibited by gradient constraints.
3Reliability
If the system provides only routes within permissible gradient range, then the vehicle stability is ensured, but no route is provided when steep slopes are unavoidable
Solution Approach 1:
The system achieves multi-functionality by serving dual purposes: it provides routes within permissible gradient ranges for stable travel, and simultaneously provides route information with preparation requirements for steep slopes when necessary. This universal approach ensures the system remains useful in all scenarios - whether the vehicle can travel on gentle slopes or must prepare and traverse steeper terrain to reach the destination.
Solution Approach 2:
The system converts the harmful aspect of steep slopes into beneficial information by identifying specific locations requiring preparation. By transforming the previously prohibitive steep slope condition into actionable preparation information, the system turns what was once a route-blocking hazard into a manageable challenge, enabling complete route information provision while maintaining stability through advance preparation.

AI summary
When deriving a preparation-unrequired route which enables a construction machine to travel only within a permissible range of a gradient until reaching a destination, a controller causes an output part to output information about the preparation-unrequired route. When not deriving the preparation-unrequired route, the controller determines a location which needs preparation for a specific landform to enable the construction machine to travel only within the permissible range of the gradient until reaching the destination, and causes the output part to output information about the location which needs the preparation and about the traveling route.
