Swingable Louver Wind Intake for Saddled Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traveling wind intake structures for saddled vehicles face challenges in efficiently guiding wind to vehicle occupants, particularly on larger vehicles, and often result in complex internal vehicle body cover designs.
Innovation Solution
A traveling wind intake structure featuring a meter visor and wind screen with a gate-type louver member and leg members that allow the louver member to swing frontward and rearward, utilizing upper and lower surfaces to change wind direction, and including wing portions and inclined surfaces to guide wind effectively, without the need for an internal wind passage within the vehicle body cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a baffle plate portion is formed in front of the meter visor to guide traveling wind, then wind guidance is improved, but the structure becomes complex and cannot adapt to large vehicle sizes
Solution Approach 1:
The patent employs a swingable louver member that can rotate between a closed position (blocking wind) and an open position (allowing wind passage). This dynamic mechanism replaces static baffle plates, enabling adaptive wind guidance for different vehicle sizes and occupant positions without increasing structural complexity. The louver member is pivotally mounted and can be actuated by simple mechanical linkages connected to the wind screen assembly.
Solution Approach 2:
The wind screen assembly integrates multiple functions: it provides wind protection, houses the swingable louver member for wind guidance, and includes linkage mechanisms for actuation. This multi-functional design eliminates the need for separate complex baffle plate structures, achieving efficient wind guidance adaptable to various vehicle configurations through a single integrated assembly.
2Ease of operation
If an inner wind passage is formed within the vehicle body cover to guide traveling wind, then wind guidance is improved, but the vehicle body cover becomes complicated
Solution Approach 1:
The patent extracts the wind guidance function from the vehicle body cover by placing the louver member in the wind screen assembly instead. The louver member handles wind direction control externally, eliminating the need for complex internal wind passages within the vehicle body cover. This separation simplifies the vehicle body cover structure while maintaining effective wind guidance through the extracted louver mechanism.
3Adaptability or versatility
If the louver member is made swingable to change wind direction, then adaptability to occupant position is improved, but the mechanism becomes more complex
Solution Approach 1:
The louver member is designed to swing between closed and open positions to adapt wind guidance to different occupant positions and preferences. The swing mechanism uses simple pivotal mounting with mechanical linkages connected to the wind screen assembly, providing adaptability without complex control systems. The mechanism can be actuated through basic mechanical means, maintaining simplicity while achieving versatile wind direction control.

Function Achieved in This Case
This solution allows for efficient wind guidance towards vehicle occupants, simplifies the structure by eliminating the need for internal wind passages, and prevents interference noise and foreign matter reaching the guide member, while maintaining effective wind direction adjustment.
Implementation Method 1
a gate-type louver member (40) is provided between the wind screen (30) and the meter visor (20), and is formed by a plate-shaped guide member (41) for guiding rearward the traveling wind (W1) introduced through the introduction portion (15)
