Truck Cabin Steering Wheel Projection for Lower Windshield Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing information displays in truck cabins occupy significant space, reducing visibility by creating a blind spot in front of the cabin and obstructing the lower part of the windshield.
Innovation Solution
Projecting essential operational information onto the steering wheel using a projector, eliminating the need for traditional dashboard displays and allowing the dashboard to be lowered, thus increasing visibility by using the steering wheel as a display surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information displays are located high on the dashboard, then all drivers can see them, but they occupy vertical space and block the lower part of the windshield
Solution Approach 1:
The patent extracts the information display function from the dashboard structure entirely and relocates it to the steering wheel. This removal eliminates the need for vertical placement on the dashboard that would block the lower windshield area
Solution Approach 2:
The steering wheel serves multiple functions: it remains the primary steering control while also functioning as a display surface for operational information. This multi-functionality eliminates the need for separate dashboard displays

AI summary
A truck cabin for a truck, comprising a windshield, a driver's seat, a steering wheel, a dashboard and a projector projecting an image onto the steering wheel. To improve the driver's visibility in front of the truck cabin, the image projected by the projector onto the steering wheel is configured to comprise information about the operation of the truck. In a first direction of sight of a driver sitting in the driver's seat and looking at the steering wheel, the dashboard does not comprise any other information displays about the operation of the truck.
