Operation Box Display Layout to Avoid Lever View Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In work machines with a configuration that supports a pair of left and right operation levers swingable in the front-rear direction, the field of view of the operator when viewing a display device is obstructed by the operation levers.
Innovation Solution
The display device is positioned on the outer side of each swing area of the pair of left and right operation levers and is disposed on one side in the left-right direction with respect to a middle area interposed between the left and right swing areas on the upper surface of the operation box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device is disposed in front of the operation levers, then the operator can easily view the display device, but the field of view is obstructed by the operation levers when they swing in the front-rear direction
Solution Approach 1:
The display device is repositioned from a central front position to a lateral position on the operation box. Specifically, it is disposed on one side in the left-right direction with respect to the middle area between the operation levers, and on the outer side of each swing area. This spatial relocation in the left-right dimension eliminates the obstruction problem while maintaining accessibility.
2Ease of operation
If the operation levers are positioned centrally for easy operation, then the operator can easily reach them, but they obstruct the view of the display device when swung forward
Solution Approach 1:
The operation box surface is segmented into distinct functional zones: the middle area between the levers, the swing areas of the levers, and the lateral display area. By assigning the display device to a separate lateral zone rather than placing it in the central area, the design allows both the levers and display to coexist without functional interference.
Solution Approach 2:
The display device is relocated from the front-center dimension to the lateral left-right dimension. This dimensional shift positions the display on the outer side of each swing area, allowing the levers to swing freely in the front-rear direction without blocking the display view.

AI summary
A work machine includes an operation box that is disposed in front of a driver's seat and supports a pair of left and right operation levers protruding upward from an upper surface so as to be swingable in a front-rear direction. The operation box has a display device that is disposed on the upper surface and notifies a state of the work machine. On the upper surface, the display device is disposed on an outer side of each swing area of the pair of left and right operation levers and is disposed on one side in a left-right direction with respect to a middle area interposed between the left and right swing areas.
