Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing work machines require cumbersome operations and risk erroneous cylinder selection due to the need to switch between tilt and angle movements, leading to potential misunderstandings and inefficiencies in soil removal tasks.
Innovation Solution
An operation system with individually provided first and second operation elements for angle and tilt movements of the blade, allowing separate control without the need for additional selection switches, enhancing operational ease and reducing the likelihood of errors.
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 switching operations and risk of erroneous cylinder selection
Solution Approach 1:
The single operation element is divided into two separate operation elements: a first operation element for angle movement and a second operation element for tilt movement. This segmentation eliminates the need for cylinder selection switching, allowing the operator to directly control each blade movement function independently, thereby improving ease of operation while maintaining acceptable device complexity
Solution Approach 2:
Each operation element is designed to be dedicated to a specific function (first for angle, second for tilt), making the operation system more universal in terms of direct control. The separation allows each element to be optimized for its specific purpose without the complexity of multi-function switching mechanisms
2Ease of operation
If separate operation elements for angle and tilt movements are provided, then the ease of operation is improved by eliminating switching operations, but the device complexity increases due to additional operation elements
Solution Approach 1:
The operation system is segmented into dedicated first and second operation elements for angle and tilt movements respectively. This segmentation improves ease of operation by eliminating the need for cylinder selection switches, and the increased device complexity is offset by the elimination of switching mechanisms and reduction in operational steps
3Reliability
If cylinder selection switch is required before operating tilt/angle switch, then the reliability of cylinder selection is improved, but the productivity deteriorates due to additional operation steps and time consumption
Solution Approach 1:
The operation elements are segmented into dedicated first operation element for angle movement and second operation element for tilt movement. This segmentation eliminates the need for preliminary cylinder selection steps, allowing direct control of blade movements, thereby improving productivity by reducing operation time while maintaining reliability through dedicated function assignment
Solution Approach 2:
The system eliminates the need for preliminary cylinder selection actions by directly assigning specific operation elements to specific cylinders. The first operation element directly controls the angle cylinder and the second operation element directly controls the tilt cylinder, removing unnecessary preliminary steps and improving overall operational efficiency

AI summary
[Problem] 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. [Solution] An operation system 2 is an operation system 2 for a work machine provided with a soil removal device including a blade. The operation system 2 includes an operation lever 21, a first operation element 201, and a second operation element 202. The operation lever 21 accepts a lifting operation for causing the blade to perform lifting movement. The first operation element 201 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 202 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 201 and the second operation element 202 are individually provided.
