Cab Door Display Layout for Loader Situational Awareness
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 need for operators to constantly switch between viewing the work area and display panels mounted in corners of the cab.
Innovation Solution
Integration of a display into the cab door that allows for partial visibility of the work area and provides augmented reality features, such as obstacle representations and defined paths, enabling operators to maintain focus on the task while receiving critical information.
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 patent combines the display panel with the cab door structure, merging the information display function with the existing door component. This integration allows the display to be positioned where the operator naturally looks when entering or exiting the cab, providing operational information without requiring the operator to shift attention from the work area.
Solution Approach 2:
The display is positioned on the vertical surface of the cab door rather than on horizontal surfaces or corners, utilizing the vertical dimension of the door structure. This strategic placement brings the display into the operator's natural line of sight when approaching or leaving the cab, eliminating the need to look away from the work area.
2Ease of operation
If the operator looks through the cab door glass to view the work area, then situational awareness is maintained, but display information becomes difficult to see
Solution Approach 1:
The display panel is positioned at a specific location on the cab door that corresponds to the operator's line of sight when approaching or entering the cab. This localized placement ensures that the display information is visible without requiring the operator to shift their gaze from the work area, as the display appears in the same visual field.
3Productivity
If display panels are positioned away from the operator's line of sight, then the work area remains fully visible, but the operator must constantly shift attention between the work area and display
Solution Approach 1:
The display function is merged with the cab door structure, positioning the display in the operator's natural line of sight when approaching or entering the cab. This integration eliminates the need for separate display locations that would require attention switching, allowing the operator to maintain continuous awareness of both operational information and the work area.
