Remote-Control Lever Support Structure for Narrow Rail Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-control lever systems in working vehicles experience 'shaking' and vibration issues when the lateral width of the fixed rail is narrow, affecting the operation and stability of the remote-control lever during vehicle travel.
Innovation Solution
A remote-control unit with a fixed rail, movable rail, and support members, where the movable rail engages slidably with the fixed rail, and additional support members are positioned differently to stabilize the remote-control lever, using resin members and bolts to secure the support structure, effectively reducing 'shaking' and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the lateral width of the fixed rail is narrowed to reduce the console box width, then the arrangement restriction in the cabin is reduced, but shaking is generated in the console box when operating the remote-control lever
Solution Approach 1:
The invention introduces a support member disposed in the vertical direction (another dimension) to stabilize the console box. Instead of relying solely on the lateral width of the fixed rail, the support member extends from the fixed rail support in the vertical direction to support the movable rail support, creating a three-dimensional support structure that prevents shaking without increasing the lateral width.
2Area of moving object
If the lateral width of the fixed rail is narrowed, then the console box width is reduced, but the remote-control lever vibrates when the working vehicle is traveling
Solution Approach 1:
The support member provides additional support in the vertical dimension, creating a more rigid three-dimensional structure. This vertical support element connects the fixed rail support to the movable rail support, preventing vibration and instability that would occur with a narrow fixed rail, while maintaining the compact lateral width of the console box.
3Stability of the object's composition
If the lateral width of the fixed rail is sufficient to prevent shaking, then the remote-control lever operates smoothly, but the lateral width of the console box becomes wide imposing restriction on arrangement in cabin
Solution Approach 1:
The invention transitions from a two-dimensional solution (increasing fixed rail width) to a three-dimensional solution by adding a vertical support member. This allows the console box to maintain sufficient stability for smooth remote-control lever operation while keeping the lateral width compact, as the stability is achieved through vertical support rather than lateral expansion.

AI summary
A remote-control unit is provided that suppresses the generation of “shaking” in a remote-control lever when the remote-control lever is operated. The remote-control unit includes a remote-control lever, a fixed rail, a movable rail, a first support member, and a second support member. The fixed rail and the first support member are fixed to a working vehicle, the movable rail slidably engages with the fixed rail, and is configured to be movable in a direction that the fixed rail is disposed. The first support member supports the second support member by way of a first resin member at a position different from a position on the fixed rail and from a position on an extension of the fixed rail.
