Shovel Ground Detection and Route Control for Soft Soil Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction sites often face difficulties in visually recognizing and avoiding soft ground regions due to their location and geography, which can hinder shovel movement and efficiency.
Innovation Solution
A shovel equipped with a determination part that assesses the ground for soft regions and a control part that allows it to travel a predetermined distance only if no soft ground is detected, along with a construction management system that communicates route information to other shovels to avoid such areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the shovel travels without ground condition detection, then the shovel can move freely and maintain high productivity, but the shovel may enter soft ground regions causing operational delays and reduced efficiency
Solution Approach 1:
The determination part performs ground condition assessment before the shovel travels, identifying soft ground regions in advance. This preliminary detection allows the control part to prevent entry into problematic areas before they cause operational delays, thus maintaining productivity while avoiding time loss.
Solution Approach 2:
The system continuously monitors ground conditions through the determination part and uses this feedback information to control the shovel's movement. The control part receives real-time data about soft ground regions and adjusts the shovel's travel accordingly, creating a closed-loop system that optimizes both productivity and avoids operational delays.
2Loss of time
If the shovel implements ground detection and control systems, then the shovel can avoid soft ground regions and reduce operational delays, but the device complexity increases
Solution Approach 1:
The determination part serves multiple functions: it detects soft ground regions, assesses ground conditions, and provides information for route planning. By making this component multi-functional, the system reduces the need for separate dedicated devices for each function, thereby managing device complexity while achieving the goal of reducing operational delays.
Solution Approach 2:
The control part integrates the ground condition data from the determination part with the shovel's travel control functions. By merging the detection and control functions into a unified system rather than separate independent systems, the patent reduces overall device complexity while maintaining the capability to avoid soft ground regions and minimize operational delays.
3Productivity
If the construction management system communicates route information between shovels, then multiple shovels can coordinate to avoid soft ground regions and improve overall efficiency, but the device complexity and communication requirements increase
Solution Approach 1:
The construction management system acts as an intermediary that collects ground condition data from multiple shovels, processes this information centrally, and distributes optimized route information back to the shovels. This intermediary approach allows complex coordination between multiple shovels without requiring direct complex communication between each pair of shovels, thereby managing system complexity while improving overall productivity.
Solution Approach 2:
The construction management system creates and distributes copies of route information to multiple shovels based on centralized analysis. Rather than requiring each shovel to independently analyze and communicate with every other shovel, the system generates route recommendations once and distributes them as copies to all relevant shovels, reducing communication complexity while maintaining coordinated operation and improving overall efficiency.

AI summary
A shovel includes a determination part that presses a working portion of an end attachment against a ground, and determines presence or absence of a soft ground region in the ground, and a control part that permits the shovel to travel by a predetermined distance in response to the determination part determining the absence of the soft ground region.
