Cab Door Display Layout for Loader Work Area Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power machines, particularly compact loaders, face challenges in maintaining situational awareness and operational efficiency during repetitive tasks due to the placement of display panels in corners of the cab, which obstruct the operator's view of the work area.
Innovation Solution
Integration of a display into the cab door that allows for augmented control and enhanced visibility of operational information, enabling the operator to maintain focus on the work area while receiving critical information through a display integrated into the cab door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If display panels are mounted in corners of the cab to provide operational information, then the operator receives necessary operational data, but the operator's view of the work area is obstructed and situational awareness is reduced
Solution Approach 1:
The display is relocated from the corner of the cab to the cab door, changing the spatial dimension and position of the display. This allows the display to be positioned in the operator's peripheral vision or line of sight without blocking the central view of the work area, thus providing operational information while maintaining situational awareness.
2Object-affected harmful factors
If the operator focuses on the work area to maintain situational awareness, then the operator can see the work area clearly, but operational information displayed in corners is difficult to observe
Solution Approach 1:
By moving the display to the cab door, the information is presented in a different spatial location that does not compete with the central work area view. The operator can glance at the door display while maintaining focus on the work area, reducing the need to shift attention between separate locations.
3Loss of information
If display panels are positioned to be visible to the operator, then operational information is provided, but the display structures add complexity to the cab door or panel assembly
Solution Approach 1:
The display is integrated directly into the cab door assembly, merging the display function with the existing door structure. This eliminates the need for separate mounting structures and reduces overall system complexity by combining multiple functions into a single integrated component.

AI summary
Power machines and loaders having doors (1410; 1510; 1710; 1810; 1910) with an integrated display (1530; 1730; 1830; 1930) that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., that allows the operator of the machine to see the displayed information closer to the line of sight with the work area. The display can show augmented reality information about a worksite.
