Remote Operating Lever Layout for Unobstructed Work Machine Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In work machines, remotely operating mechanisms can occupy space on the operator's seat, obstructing movement and direct operation of the operating lever, making it difficult for the operator to control the machine effectively.
Innovation Solution
The work machine design includes an operating mechanism with a first direction guide member and actuator that tilts the operating lever based on an operation command, with the actuator positioned on the opposite side of the seat, allowing sufficient space for the operator and preventing obstruction of the control panel and getting-in/out passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an operating mechanism for remotely operating the operating lever is attached to the work machine, then remote operation capability is improved, but the operating mechanism occupies space on the seat and obstructs operator movement
Solution Approach 1:
The actuator is extracted from the console box and installed separately on the seat, removing the space-occupying component from the operator's immediate workspace while preserving the remote operation function
Solution Approach 2:
A connection rod is introduced as an intermediary element to transmit the driving force from the actuator to the operating lever, enabling remote operation control without requiring the actuator to be positioned near the lever
2Device complexity
If the actuator is installed on the console box to tilt the operating lever, then the operating mechanism structure is simplified, but the actuator obstructs the control panel and getting-in/out passage
Solution Approach 1:
The actuator is extracted from the console box and repositioned on the seat, eliminating the obstruction to the control panel and getting-in/out passage while maintaining the tilting function through the connection rod mechanism
Solution Approach 2:
The actuator is positioned in a different spatial location (on the seat rather than on the console box), changing the spatial arrangement to avoid obstruction of critical areas while preserving functional connectivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables remote operation of the work machine while maintaining a sufficient space on the seat for the operator and preventing obstruction of the control panel and passage, enhancing operational flexibility and safety.

AI summary
A first operating mechanism 7 of a work machine 1 includes a first guide member 74 which tilts a fourth operating lever 5 in the right-left direction, and a first actuator 72 which generates a driving force for tilting a first direction guide member 74 on the basis of an operation command. The first actuator 72 is disposed at a position on the opposite side of the fourth operating lever 5 from a slave-side seat 3.
