Motorcycle Meter Visor with Upper Window for Forward Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional straddle type vehicles, such as motorcycles, position the meter rearward due to a windshield in front of the meter visor, increasing the rider's eye movement for visual recognition, which is undesirable.
Innovation Solution
A design featuring a meter visor with a window above the meter unit, covered by a lower screen with reduced transmittance and an upper screen, supported by a convex arch-shaped stay, allowing the meter unit to be positioned forward and reducing eye movement for the rider while maintaining forward visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a windshield is disposed in front of the meter visor, then the rider is protected from traveling winds, but the meter is positioned rearward increasing eye movement
Solution Approach 1:
The windshield is divided into an upper screen and a lower screen with different functions. The lower screen covers the meter visor area to protect from winds while the upper screen extends forward to allow the meter to be positioned forward, reducing eye movement. This segmentation resolves the contradiction by separating the wind protection function from the visibility function.
Solution Approach 2:
The upper screen extends forward in the longitudinal dimension beyond the lower screen, creating a stepped configuration. This dimensional extension allows the meter to be positioned forward while the lower screen maintains wind protection, thus reducing eye movement without sacrificing wind protection.
2Illumination intensity
If the lower screen has reduced transmittance, then visibility is improved, but light transmission is reduced
Solution Approach 1:
Different parts of the windshield have different transmittance properties. The lower screen has reduced transmittance to improve visibility and reduce glare for the rider, while the upper screen has higher transmittance to allow sufficient light to reach the rider's eyes. This local differentiation resolves the contradiction between visibility improvement and light transmission.
3Ease of operation
If the meter is positioned forward, then eye movement is reduced, but the windshield structure becomes more complex
Solution Approach 1:
The windshield is segmented into two screens with different positions and functions. The lower screen protects the meter area while the upper screen extends forward to accommodate the forward-positioned meter. This segmentation allows the meter to be positioned forward for reduced eye movement while maintaining a manageable structural complexity through functional division.
