Movable Control Panel for Commercial Vehicle Operator Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arrangements of operating and display elements in commercial vehicles are not optimally positioned, making it difficult to reach controls and read displays during working mode operations.
Innovation Solution
A second control panel with operating and display elements for working functions is positioned optimally by being moved using a pivoting and sliding bracket attached to the armrest, allowing better access to controls and visibility of displays, distinct from the driving mode panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional control panels are arranged in the area of the operator's seat, then control functions for working devices are provided, but the operating elements are difficult to reach and display elements are not easy to read
Solution Approach 1:
The second control panel is made movable rather than fixed, allowing it to be positioned dynamically. The holder with sliding and pivoting capabilities enables the control panel to be adjusted to optimal positions for both driving and working modes, resolving the contradiction between providing additional control functions and maintaining ease of operation.
Solution Approach 2:
The control panel is moved from a two-dimensional fixed position on the dashboard to a three-dimensional adjustable position using the holder mechanism. This allows the panel to be positioned in multiple spatial dimensions (height, angle, horizontal position) to optimize accessibility and readability while maintaining all control functions.
2Device complexity
If fixed control panels are used for working functions, then the structure is simple, but the controls cannot be optimally positioned for different operating modes
Solution Approach 1:
The holder mechanism introduces controlled dynamics to an otherwise simple structure. The sliding and pivoting components add minimal complexity while enabling the control panel to adapt to different operating modes, achieving optimal positioning without requiring multiple separate control panels.
3Adaptability or versatility
If multiple control panels are arranged for driving and working functions, then all control functions are available, but operating errors occur due to poor positioning
Solution Approach 1:
The movable second control panel allows the operator to position controls optimally for each operating mode, reducing the likelihood of operating errors. By enabling dynamic adjustment rather than relying on fixed positioning, the system maintains both functional versatility and operational reliability.

AI summary
An arrangement of operating and/or display elements in a commercial vehicle with an operator's seat and at least one control panel and an armrest located adjacent to the operator's seat, wherein the control panel comprises operating and/or visually perceptible display elements to be operated by the operator, and wherein the commercial vehicle can be operated in a driving mode and a working mode. To create an improved arrangement for additional control panels, preferably assigned to work equipment to be arranged on and/or attached to the commercial vehicle, it is provided that at least one first, preferably fixed, and at least one second movable control panel are provided, and that the second control panel can be moved relative to the first control panel from a first position to the side of the operator's seat to a second position at least partially in the direction above the thighs and in front of the upper body of the operator sitting on the operator's seat.
