Construction Equipment Display Layout for Multi-App Cabin Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The spatial constraints of the cabin in construction equipment limit the number of display devices that can be mounted, leading to situations where desired display devices cannot be installed and multiple devices can obstruct the driver's forward view.
Innovation Solution
A system that uses a control device to manage and display execution screens of multiple applications across a limited number of display devices, allowing for flexible layout modes such as entire screen and divided screen modes, which can be determined based on application attributes and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices are mounted in the cabin to support various services, then the quantity of services is improved, but the driver's forward view is obstructed
Solution Approach 1:
The patent transitions from a two-dimensional display arrangement (multiple displays mounted on cabin walls) to a three-dimensional projection system that displays information in the air space above the dashboard. This dimensional change allows multiple services to be displayed without occupying physical cabin space that would obstruct the driver's view.
Solution Approach 2:
The patent introduces an intermediary device (projection system or holographic display) that mediates between the need to display multiple services and the need to maintain clear visibility. This intermediary projects virtual displays that can be viewed without physical mounting in the driver's line of sight.
2Adaptability or versatility
If multiple display devices are mounted in the cabin to support various services, then the quantity of services is improved, but the device complexity is increased
Solution Approach 1:
The patent implements a universal projection system that can display multiple different services simultaneously on a single projected interface. Instead of requiring separate physical displays for each service (cluster, AVM, 3D guidance, HVAC, radio, weighing, tilt-rotator), one projection system handles all functions through virtual display areas.
Solution Approach 2:
The patent merges multiple separate display functions into a single integrated projection system. Multiple virtual display areas are combined in one projected space, allowing the driver to access various services through one unified interface rather than multiple separate physical devices.
3Adaptability or versatility
If display devices are mounted inside the cabin to provide services, then the service functionality is improved, but the spatial constraints are exceeded
Solution Approach 1:
The patent utilizes the third dimension (vertical air space above the dashboard) to display service information, transforming the problem from a 2D space constraint to a 3D solution. This allows multiple virtual displays to coexist in the available air space without requiring additional cabin wall mounting areas.
