Motorcycle Frame Cover Integration via Locking Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-wheeled motor vehicles experience deviations and wobble at the join between the outside frame and exterior cover due to indirect fixation, leading to a lack of seamless integration and rigidity, especially when subjected to forces from knee gripping or similar actions.
Innovation Solution
The solution involves forming and arranging exterior parts to create a continuous, seamless appearance with direct fixation between the outside frame and exterior cover, utilizing protrusions and a locking structure that extends towards the exterior cover for rigid fixation, thereby improving integration and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outside frame and exterior cover are individually fixed to the vehicle frame through separate attachment structures, then each member can be independently positioned, but deviation arises in relative position and wobble occurs at the join between members
Solution Approach 1:
The patent merges the outside frame and exterior cover into a unified assembly where the exterior cover is integrally formed with the outside frame. This integration eliminates separate attachment structures and ensures precise relative positioning without deviation or wobble at the join between members.
2Ease of manufacture
If multiple exterior parts are arranged next to each other with indirect fixation through vehicle frame attachments, then each part can be separately assembled, but the appearance becomes non-seamless and integration is poor
Solution Approach 1:
The exterior cover is designed to extend continuously from the outside frame, creating a seamless appearance. The integral formation ensures that the transition between exterior parts is smooth and continuous, eliminating visual discontinuities while maintaining ease of assembly as a unified component.
3Adaptability or versatility
If the outside frame and exterior cover are indirectly fixed through attachment structures on the vehicle frame, then each member has independent mounting flexibility, but rigidity and resistance to external forces are reduced
Solution Approach 1:
By integrating the exterior cover with the outside frame, the assembly forms a rigid unified structure that effectively resists external forces such as knee gripping. The continuous material connection eliminates weak points at attachment interfaces while maintaining mounting flexibility through the overall assembly design.

AI summary
Atwo-wheeledmotorvehicle includes: an outside frame arranged to be exposed to a side of the vehicle; and an exterior cover arranged to be exposed to the side of the vehicle and having first and second cover surfaces that extend toward the outside frame, the first and second cover surfaces being arranged to make an angle therebetween. The outside frame has: a frame end surface facing the exterior cover having a locking structure formed thereon which extends to a position overlapped with the exterior cover in a side view and locks the exterior cover; a first frame surface which extends continuous from the first cover surface; and a second frame surface which extends continuous from the second cover surface. Accordingly, integration between exterior parts is improved.
