Steering-Mounted Display for Two-Wheeled Vehicle Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-wheeled vehicles with touch-screen displays positioned forward of the operator require the operator to remove their hand from the steering device and lean forward to access the screen, disrupting control and comfort during operation.
Innovation Solution
A display system integrated with the steering assembly, positioned rearward of the fuel tank and vertically aligned with the engine cylinders, allowing the display to move with the steering assembly and remain within the operator's reach without leaning, featuring a touch-screen display with adjustable tilt and push buttons for input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display is positioned forward of the operator to provide information, then the operator can access information, but the operator must remove hand from steering device and lean forward
Solution Approach 1:
The display is merged with the steering assembly, creating an integrated unit where the display moves together with the steering components. This allows the display to be positioned within the operator's natural reach zone while maintaining hand contact with the steering device, as the display becomes part of the steering assembly itself rather than a separate forward-mounted component
2Loss of information
If the display is positioned forward of the operator, then information is visible, but the operator must lean forward to reach the display
Solution Approach 1:
The display is configured to move with the steering assembly, creating a dynamic positioning system. As the steering assembly moves or adjusts, the display moves accordingly to maintain an optimal position within the operator's reach zone, eliminating the need for the operator to lean forward while ensuring information remains visible
3Ease of operation
If the display is integrated with the steering assembly, then the display moves with steering assembly, but the display position must be precisely controlled
Solution Approach 1:
By merging the display with the steering assembly as a single integrated unit, the patent eliminates the need for separate positioning mechanisms. The display inherits the steering assembly's mounting structure and movement characteristics, thereby achieving precise ergonomic positioning without adding complex independent control systems

AI summary
A vehicle (2) has a longitudinal centerline and comprises a plurality of ground-engaging members (4, 6), a seat (18) supported by the plurality of ground-engaging members, a fuel tank (38) positioned adjacent the seat, a steering assembly (42) operably coupled to at least one the ground-engaging members, and a display (70-74) movable with the steering assembly and intersecting the longitudinal centerline of the vehicle. The display is positioned rearward of a front plane of the fuel tank.
