Saddled Vehicle Air Guide Mounting via Nested Cowl Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddled vehicles with air guide members mounted on the front cowl have exposed mounting portions that impair the appearance.
Innovation Solution
The saddled vehicle design includes a cowl with a front cowl and a front lateral cowl, where the air guide member is mounted between these two components, with a support part inserted into an opening in the front cowl and covered by the front lateral cowl, ensuring the mounting portion is not exposed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air guide members are mounted on the front cowl using a bolt, then the air guide member is firmly yet readily mounted, but the mounting portion being exposed to the outside impairs the appearance
Solution Approach 1:
The mounting function is extracted from the visible air guide member and transferred to a separate support part that is inserted into the front cowl. The support part contains the mounting hole and is positioned inside the cowl, separating the mounting mechanism from the external appearance.
Solution Approach 2:
The support part is nested within the front cowl structure. The support part is inserted into the front cowl through an opening, and its position is secured by the front lateral cowl, creating a nested arrangement where the mounting component is hidden within the cowl assembly.
2Ease of operation
If the support part is inserted into the opening from the outer side, then the air guide member is easily assembled, but the support part may be exposed unless covered
Solution Approach 1:
The front lateral cowl acts as an intermediary component that covers the opening in the front cowl. It serves as a mediator between the support part (which needs to be hidden) and the external environment, blocking the view of the support part while allowing the air guide member to function normally.
3Reliability
If the vehicle widthwise dimension of the support part is longer than the distance between front cowl and front lateral cowl, then the support part is securely held, but the design complexity increases
Solution Approach 1:
The support part extends in the vehicle width direction (lateral dimension) rather than only in the depth direction. By making the support part's vehicle widthwise dimension longer than the distance between the front cowl and front lateral cowl, the support part is securely held between these two components, utilizing the lateral dimension for securing purposes.

AI summary
To provide a saddled vehicle having air guide members firmly yet readily mounted on its front cowl while keeping the mounting portion unobtrusive.A saddled vehicle includes: a cowl that covers a front part of the saddled vehicle; a windshield screen disposed at an upper part of the cowl; and an air guide member separately from the windshield screen mounted on the cowl. The cowl includes a front cowl that covers an outer circumference of a headlamp and a front lateral cowl that covers an outer side in the vehicle width direction of the front cowl. The air guide member includes a support part held between front cowl and the front lateral cowl. The front cowl has an opening. The support part is inserted into the opening from the outer side in the vehicle width direction. The opening and the support part are covered with the front lateral cowl.
