Straddled Vehicle Meter Unit Dual Screen Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of straddled vehicles face difficulty in intuitively recognizing display contents on meter units due to indistinct boundaries between images on elongated screens, leading to visibility issues and reduced forward visibility.
Innovation Solution
The meter unit is designed with two screens, one on either side of the vehicle center, inclined at 45 degrees or more, with distinct boundaries and reduced content to enhance visibility and prevent glare, allowing for easier recognition of display contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple display contents are shown on one screen, then information density is improved, but boundary distinctness deteriorates
Solution Approach 1:
The patent divides the display system into multiple independent screens (first screen and second screen), each displaying a subset of display contents. This segmentation creates clear physical boundaries between different image groups, solving the problem of indistinct boundaries when multiple contents are shown on a single screen.
2Difficulty of detecting and measuring
If screens are arranged side by side in transverse direction, then boundary distinctness is improved, but forward visibility deteriorates
Solution Approach 1:
The patent tilts the screens forward and upward at an angle of 45 degrees or more relative to the horizontal plane, transitioning from a purely transverse arrangement to a three-dimensional configuration. This dimensional change allows the screens to be arranged side by side while reducing their projection area in the forward direction, thereby maintaining boundary distinctness while preserving forward visibility.
3Object-affected harmful factors
If screens are inclined forward and upward, then glare is reduced, but visibility of end portions deteriorates
Solution Approach 1:
The patent positions the first screen leftward of the vehicle center plane and the second screen rightward of the vehicle center plane, creating an asymmetric layout relative to the driver's position. This asymmetric arrangement, combined with the forward and upward tilt, optimizes the angle of incidence for sunlight, reducing glare on the screens while maintaining visibility of all portions including the end portions.

AI summary
Disclosed is a straddled vehicle (1) including a meter unit (29). The meter unit (29) includes a first display (41) and a second display (42). The first display (41) includes a first screen (43). The second display (42) includes a second screen (44). The first screen (43) is located leftward of a vehicle center plane (C). The second screen (44) is located rightward of the vehicle center plane (C). The first screen (43) and the second screen (44) are each inclined forward and upward at an angle (θ1) of 45 degrees or more relative to a horizontal plane (G). The first screen (43) is inclined leftward and rearward in plan view of the vehicle. The second screen (44) is inclined rightward and rearward in plan view of the vehicle. The first display (41) and the second display (42) are arranged side by side in a transverse direction (Y) and are spaced apart from each other. The meter unit (29) forms a center space (S).
