Work Machine Display System for Motion and Operation State Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machine display systems fail to effectively convey both motion and operation states, making it difficult for operators to recognize and control the machine efficiently.
Innovation Solution
A display system that obtains and generates motion and operation images based on the work machine's information, allowing for easy recognition of both states through a system comprising an obtaining unit, motion image generator, and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only motion information is displayed, then the motion state is shown, but the operation state cannot be recognized
Solution Approach 1:
The patent segments the display information into two distinct types: motion images showing the work implement's position and attitude, and operation images showing the operator's lever positions. This segmentation allows each type of information to be presented clearly without overwhelming the operator, while together they provide complete situational awareness.
Solution Approach 2:
The patent merges motion information and operation information into a unified display system that presents both types of images simultaneously. The motion image generator and operation image generator work together to create complementary visual representations that are displayed in coordination, allowing the operator to recognize both motion and operation states together.
2Loss of information
If detailed operation information is provided, then operation state is recognizable, but the display becomes complex and hard to read
Solution Approach 1:
The patent applies local quality by providing detailed operation information only where needed - specifically showing lever positions and their correspondence to motion states - rather than overwhelming the display with all possible parameters. The operation image is localized to show only the relevant control inputs.
Solution Approach 2:
The patent creates simplified visual copies of the actual operation states through graphical representations of lever positions and motion images. These copies are easier to interpret than raw sensor data while still accurately representing the operational state, making the information both visible and readable.
3Loss of information
If multiple types of information are displayed together, then complete machine state is shown, but the display becomes cluttered and difficult to interpret
Solution Approach 1:
The patent adds a new dimension to the display by showing operation information in relation to motion information through coordinated images. The operation image and motion image are presented in a way that shows their temporal and causal relationship, allowing the operator to understand how control inputs translate to machine motion without cluttering a single space.

AI summary
A display system of a work machine includes an obtaining unit that obtains motion information and operation information of the work machine, a motion image generator that generates a motion image of the work machine and an operation image corresponding to the motion image of the work machine based on the motion information and the operation information obtained by the obtaining unit, and a display that shows the motion image and the operation image of the work machine.
