Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work machines operating at sites with cliffs, such as mines, may reduce productivity due to unawareness of cliff presence.
Innovation Solution
A detection system comprising a three-dimensional data acquisition unit, current terrain data storage unit, and determination unit to recognize cliffs based on acquired data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If work machines operate without cliff detection systems, then device complexity is reduced, but productivity is reduced due to unrecognized cliffs
Solution Approach 1:
The three-dimensional data acquisition unit is designed to perform multiple functions: it captures terrain data for cliff detection, stores current terrain data with temporal information, and enables determination of cliff presence. This multi-functional approach allows a single device to handle various detection and analysis tasks, improving productivity without proportionally increasing device complexity
Solution Approach 2:
The patent introduces terrain data as an intermediary element that mediates between the physical cliff environment and the work machine's decision-making system. By capturing, storing, and analyzing terrain data, the system creates an information layer that enables indirect detection of cliffs, allowing work machines to recognize hazards without direct physical interaction
2Productivity
If cliff detection systems are implemented, then productivity is improved by recognizing cliffs, but device complexity increases
Solution Approach 1:
The detection system is designed to autonomously perform cliff detection by automatically acquiring three-dimensional terrain data, storing it with temporal information, and determining cliff presence without requiring constant human intervention or complex external systems. The system serves itself by using its own acquired data to make detection decisions, thereby improving productivity while keeping operational complexity manageable
Solution Approach 2:
The system performs preliminary actions by acquiring and storing terrain data before cliff hazards become critical issues. By continuously capturing and archiving terrain information with timestamps, the system prepares detection data in advance, enabling rapid cliff recognition when needed without requiring complex real-time processing during critical moments

AI summary
A detection system for a work site includes: a three-dimensional data acquisition unit that acquires three-dimensional data of the work site where a work machine operates; a current terrain data storage unit that stores current terrain data created on the basis of the three-dimensional data and time in association with each other; and a determination unit that determines whether or not there is a cliff at the work site on the basis of storage data stored in the current terrain data storage unit.
