Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manipulation guide devices for work machines do not effectively allow operators to recognize the difference between their actual manipulations and the model manipulations, leading to suboptimal work performance.
Innovation Solution
A manipulation guide device that includes a manipulation device, a storage unit for model data, and a display unit that shows the comparison between actual manipulation data and model data over time, allowing operators to easily identify deviations and improve their performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manipulation guide image is displayed showing a manipulation for eliminating deviation, then the operator can perform correct manipulation, but the flow of a series of manipulations preferable for performing a certain work cannot be recognized by the operator
Solution Approach 1:
The manipulation guide is segmented into multiple components: a time-series display showing the overall manipulation flow, and a detailed manipulation guide image showing specific corrections. This segmentation allows the operator to see both the big picture flow and specific corrective actions needed at each moment.
Solution Approach 2:
The patent adds a time dimension to the manipulation guide by displaying manipulation amounts over time in a time-series graph. This temporal dimension allows operators to understand the sequence and flow of manipulations while still receiving real-time correction guidance.
2Measurement precision
If the manipulation guide shows only deviation correction, then immediate correction is provided, but the operator cannot recognize the overall manipulation flow and optimal work pattern
Solution Approach 1:
The patent merges two types of information into a single integrated display: the time-series manipulation flow data and the real-time deviation guide information. This combination allows operators to see both the overall pattern and specific deviations without switching between separate displays.
Solution Approach 2:
The time-series display acts as an intermediary between the raw manipulation data and the deviation correction guidance. It provides contextual information that helps operators understand how their current manipulation fits into the overall work pattern, while still showing precise deviation measurements.
3Reliability
If real-time manipulation comparison is provided, then operators can see deviations, but the complexity of the display system increases
Solution Approach 1:
The display system uses local quality by showing different types of information in different regions of the display. The time-series graph provides overall context in one area, while the manipulation guide image provides detailed correction information in another area, allowing the system to be comprehensive without overwhelming the operator.

AI summary
An operator is allowed to easily recognize a difference between a manipulation actually performed when performing a work and a manipulation serving a model for the work. A manipulation guide device for a work machine includes a manipulation device, a storage unit, and a display unit. The manipulation device is manipulated by an operator of the work machine to operate the work machine. The storage unit stores model data serving as a model when the manipulation device is manipulated. The display unit displays a change over time in a result of comparison between actual manipulation data about an actual manipulation of the manipulation device by the operator and model data in a time period during an operation of the work machine.
