Steering-Section Display Layout for GNSS Correction Status Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles with receivers for correction information to correct positional information face challenges in allowing operators to easily recognize the operation state of these devices, particularly when mounted outside the cabin or in retracted portions.
Innovation Solution
A work vehicle design where the correction information device is integrated into the steering section and disposed inside the cabin, with the display of its operation state being viewable from outside the cabin, either through the cabin door or from specific angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the correction information device is mounted outside the cabin or in retracted portions, then the device can be installed with simpler structure, but the operator cannot easily recognize the operation state of the device
Solution Approach 1:
The patent introduces a display unit as an intermediary component that mediates between the correction information device (mounted outside or in retracted portions) and the operator (inside the cabin). The display unit converts the operation state into visible information that can be perceived by the operator, thus resolving the contradiction between simple installation and easy recognition of operation state.
Solution Approach 2:
The patent moves the operation state information from the physical dimension (where the device is mounted outside or in retracted portions) to the visual information dimension (display unit showing operation state). This dimensional transformation allows the operator to recognize the operation state without direct physical access to the device, maintaining installation simplicity while improving recognizability.
2Ease of operation
If the correction information device is mounted inside the cabin in the steering section, then the operation state becomes easily recognizable by the operator, but the device may interfere with the operator's tasks
Solution Approach 1:
The patent segments the correction information device into two separate components: the receiving device (mounted outside or in retracted portions for simple installation) and the display unit (mounted inside the cabin for easy recognition). This segmentation resolves the contradiction by allowing each component to be optimally positioned without interfering with the operator's tasks while maintaining recognizability.
Solution Approach 2:
The display unit serves as an intermediary that bridges the gap between the correction information device and the operator. It allows the operation state to be recognized without requiring the physical presence of the entire device in the operator's workspace, thus avoiding interference with operational tasks while maintaining ease of recognition.
3Loss of information
If the display is made viewable from outside the cabin through the door, then external visibility is improved, but the display may be obscured when the door is closed
Solution Approach 1:
The patent applies local quality by positioning the display unit with specific directional characteristics - the display surface is oriented to be viewable from outside the cabin through the door when open. This localized optimization of display orientation allows external visibility without requiring complex positioning mechanisms, resolving the contradiction between external visibility and positioning complexity.

AI summary
A work vehicle including a device that receives positional information in a work site includes a correction information terminal that receives correction information for correcting the positional information from a base station located outside the work site, and a steering section for steering the vehicle. The correction information terminal displays an operation state of the correction information terminal and is disposed in the steering section.
