Work Machine Blade Controls Without Cylinder Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing operation system for work machines with soil removal devices requires cumbersome operations and risks erroneous cylinder selection during transitions between angle and tilt movements.
Innovation Solution
An operation system with an operation lever, a first operation element for angle movement, and a second operation element for tilt movement, allowing these movements to be performed independently without the need for cylinder selection switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single operation element with cylinder selection switch is used to control both angle and tilt movements, then the device complexity is reduced, but the ease of operation deteriorates due to cumbersome operations and risk of erroneous cylinder selection
Solution Approach 1:
The patent divides the operation control into separate elements: a first operation element exclusively for angle movement and a second operation element exclusively for tilt movement. This segmentation eliminates the need for cylinder selection switches and prevents erroneous operation by ensuring each operation element controls only its designated cylinder, thereby improving ease of operation while maintaining reasonable device complexity.
2Ease of operation
If individual operation elements for angle and tilt movements are provided, then the ease of operation is improved by eliminating cylinder selection steps, but the device complexity increases
Solution Approach 1:
The patent merges both operation elements (first for angle, second for tilt) into a single integrated operation lever. This combining approach allows the operator to access both functions from one location without adding separate control devices, thereby improving ease of operation while minimizing the increase in device complexity. The operation lever integrates multiple control functions in a unified structure.

AI summary
To provide an operation system for a work machine, and a work machine in which it is easy to improve operability of a soil removal device. An operation system is an operation system for a work machine provided with a soil removal device including a blade. The operation system includes an operation lever, a first operation element, and a second operation element. The operation lever accepts a lifting operation for causing the blade to perform lifting movement. The first operation element accepts an operation for causing the blade to perform angle movement of rotationally swinging the blade around a first axis along a vertical direction. The second operation element accepts an operation for causing the blade to perform tilt movement of rotationally swinging the blade around a second axis along a horizontal direction. The first operation element and the second operation element are individually provided.
