Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work machines can encounter issues when traveling over boulders, which can disrupt their operation and cause damage.
Innovation Solution
A monitoring system for work machines that includes a measurement data acquisition unit to detect the presence of boulders on the ground, a boulder determination unit to identify them, and a warning control unit to alert the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the work machine travels on the ground without monitoring, then the operation is simple and fast, but the work machine may encounter boulders causing travel problems and damage
Solution Approach 1:
The system performs preliminary detection of boulders on the ground before the work machine reaches them. The detection unit scans the ground ahead, identifies boulder locations in advance, and the warning unit alerts the operator before the machine encounters the obstacle, allowing preventive action to be taken.
Solution Approach 2:
The patent introduces a detection unit and warning unit as intermediary components between the work machine and the ground. These intermediaries sense the ground conditions (boulders) and transmit this information to the operator, acting as a mediator that bridges the gap between the machine's movement and the ground obstacles.
2Object-affected harmful factors
If a monitoring system is installed to detect boulders, then the work machine can avoid travel problems, but the device complexity increases
Solution Approach 1:
The monitoring system is segmented into distinct functional units: a detection unit for identifying boulders, a determination unit for analyzing detection data, and a warning unit for alerting the operator. This segmentation allows each component to perform its specific function efficiently while keeping the overall system manageable and maintainable.
Solution Approach 2:
The patent replaces complex mechanical sensing systems with sensor-based detection units that use optical, electromagnetic, or other non-contact sensing methods to detect boulders. This substitution reduces mechanical complexity while improving detection capability and reliability.
Data Source
AI summary
A work machine monitoring system includes a measurement data acquisition unit that acquires measurement data of a ground on which a work machine travels by rotation of a rotating member included in the work machine, the rotating member contacting the ground, a boulder determination unit that determines presence or absence of a boulder on the ground in the measurement data, and a warning control unit outputs a warning from an output device based on presence or absence of the boulder on the ground in a traveling direction of the rotating member.
