Cab Door Display Integration for Loader Line-of-Sight Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power machines, such as compact loaders, face challenges in efficiently performing repetitive tasks due to the need for continuous operator intervention, which can lead to reduced efficiency and increased time consumption.
Innovation Solution
The integration of a learning mode in power machines that allows for the recording and automation of repetitive tasks, enabling the machine to perform series of operations autonomously, and the use of an integrated display in the cab door to provide operators with critical information closer to their line of sight, enhancing situational awareness and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If display panels are mounted in corners of the cab, then operational information can be provided to the operator, but the operator's situational awareness of the work area is compromised
Solution Approach 1:
The display panel is integrated into the cab door glass, transitioning from a corner-mounted 2D placement to a distributed integration across the door surface. This allows operational information to be displayed in the operator's direct line of sight through the door glass, eliminating the need to shift attention between corner displays and the work area, thereby maintaining both information access and situational awareness simultaneously
2Productivity
If the loader performs repetitive tasks manually, then the operator can control each operation, but efficiency is reduced and time consumption increases
Solution Approach 1:
The loader is equipped with a control system that enables it to perform repetitive tasks autonomously without continuous operator intervention. The machine can automatically execute sequences of operations such as transporting material, raising or lowering attachments, and returning to starting positions, thereby serving itself and eliminating the time loss associated with manual control of repetitive tasks
3Loss of information
If the cab door is made opaque for display integration, then operational information can be displayed, but visibility through the door to the work area is blocked
Solution Approach 1:
The cab door glass is designed with selectively transparent and opaque regions. The display panel is integrated into specific zones of the door glass, allowing those local areas to be opaque for information display while other portions of the door glass remain transparent to maintain visibility of the work area. This local differentiation of optical properties enables both functions to coexist without mutual interference

AI summary
Power machines and loaders having doors with an integrated display 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.
