Straddle Vehicle Side Bag Support Member Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The attachment of side bags and their support members on straddle type vehicles often requires forming attachment holes or notches in body covers, which can negatively affect the vehicle's appearance and air/wind flow.
Innovation Solution
A straddle type vehicle design where the side bag support member is positioned close to the end of the rear side cover's lower surface, minimizing the visibility of notches and holes, and featuring a side bag support part integrated into the seat or body frame, allowing for efficient load support and easy attachment/detachment of the side bag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If attachment holes or notches are formed in the body cover to attach the side bag support member, then the side bag can be detachably attached to the vehicle, but the appearance and air/wind flow of the vehicle are negatively affected
Solution Approach 1:
The side bag support member is repositioned from the conventional location on the body cover to a new location on the lower surface part of the rear side cover, specifically at its end portion. This spatial relocation in a different dimensional context allows the support member to be attached without forming visible attachment holes or notches in the main body cover, thus preserving appearance and air flow while maintaining detachable attachment functionality.
2Shape
If the side bag support member is positioned closer to the end of the rear side cover's lower surface, then the visibility of notches and holes is minimized, but the support structure must be redesigned
Solution Approach 1:
The side bag support member is divided into two functional parts: a vertical support part that provides the attachment interface, and a horizontal support part that extends to reach the side bag support part on the seat frame. This segmentation allows the support member to be positioned at the end of the rear side cover's lower surface while still providing adequate support, as the horizontal part bridges the gap between the relocated vertical part and the seat frame attachment point.
3Reliability
If a conventional large support frame is used to support the side bag, then the side bag can be securely attached, but the vehicle structure becomes more complex and less workable
Solution Approach 1:
The invention extracts and eliminates the need for a large conventional support frame by relocating the attachment point to the end of the rear side cover's lower surface. The side bag support member, with its vertical and horizontal parts, provides the necessary support function in a compact form that integrates with the existing seat frame structure, thereby securing the side bag without requiring a bulky separate support frame.

AI summary
A straddle type vehicle may be provided with a side bag support member in which a horizontal wall part is extended inward in the vehicle width direction from a vertical wall part fixed to a portion of a side bag on the inside in the vehicle width direction to an area below a lower surface part of a rear side cover, and the horizontal wall part is fixed from below to a side bag support part on a lower surface side of a seat frame.
