Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of hydraulic excavators face difficulty in visually understanding the positional relationship between the excavation tool and the target topography during excavation operations.
Innovation Solution
A display system that includes a controller to generate and display a third figure representing the relative relationship between a first figure indicating the inclination of the excavation tool and a second figure indicating the inclination of the target topography, enhancing visual understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a side view of the bucket is displayed on a display unit together with an image of the target construction topography, then information about the construction state is provided to the operator, but the positional relationship between the target topography and the excavation tool is not visually clear
Solution Approach 1:
The patent adds a new visual dimension by introducing inclination indicators (first indicator for excavation tool, second indicator for target topography) that display angular relationships. This transforms the traditional 2D positional display into a multi-dimensional representation that includes inclination angles, allowing operators to visually grasp both position and orientation relationships simultaneously.
Solution Approach 2:
The patent introduces inclination indicators as intermediary visual elements that mediate between the raw sensor data and the operator's understanding. These indicators serve as visual mediators that translate complex spatial relationships into intuitive angular representations, making the positional relationship between the excavation tool and target topography immediately comprehensible.
2Reliability
If the operator visually checks movement of the working implement and the current topography, then the operator can monitor the excavation process, but it is difficult to perform excavation to obtain target construction topography
Solution Approach 1:
The patent implements a feedback mechanism by displaying real-time inclination indicators that show the current angular relationship between the excavation tool and the target topography. This visual feedback allows operators to continuously monitor their performance and make immediate adjustments to achieve the desired construction topography with higher precision.
Solution Approach 2:
The patent changes the display parameter from simple positional information to include inclination angles. By presenting angular parameters alongside positional data, the system provides more comprehensive information that enables operators to control both the position and orientation of the excavation tool, thereby achieving more precise construction results.
