Straddled Vehicle Headlight Support via Multi-Point Handle Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddled vehicles face vibration issues due to large and heavy headlights, which require increased stiffness in the handle cover, leading to wobbling and the need for stronger surrounding components.
Innovation Solution
A straddled vehicle design featuring first and second support sections fixed to the handle, supporting the headlight in up and down positions, inhibiting vibrations and allowing the use of compact handle covers for large-sized headlights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the headlight size is increased to emit sufficient light, then the illumination intensity is improved, but the weight of the headlight increases
Solution Approach 1:
The patent transitions from single-point support to multi-point distributed support by adding support sections at different vertical positions (upper and lower support sections). This dimensional expansion in the vertical direction allows the heavy headlight to be supported at multiple locations, distributing the load and reducing vibration transmission while accommodating larger, heavier LED headlights.
2Strength
If the handle cover size is increased to support the heavy headlight, then the strength is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the headlight support function from the handle cover structure and creates independent support sections fixed to the handle. By separating the support function into dedicated components (upper and lower support sections with elastic bodies), the handle cover no longer needs to be oversized or overly complex to support the headlight, reducing overall device complexity while maintaining necessary strength.
3Device complexity
If the headlight is supported by a single location, then the device complexity is reduced, but the vibration transmission increases
Solution Approach 1:
The patent adds vertical dimension to the support structure by positioning support sections at different heights (upper and lower support sections). This multi-level vertical arrangement creates multiple support points that effectively dampen and distribute vibration energy, reducing harmful vibration transmission to the handle and controls while maintaining a relatively simple overall structure.

AI summary
It is intended to provide a straddled vehicle that can solve a vibration problem by exerting a stiffness enough to support a headlight, and simultaneously, can use a compact handle cover compatible with a large-sized headlight. The present straddled vehicle (1) includes a handle (16), a headlight (31), a handle cover (33), a first support section (44), and a second support section (45). The headlight (31) is disposed in front of the handle (16). The handle cover (33) covers the handle (16) and the headlight (31) from front and behind. The first support section (44) is fixed to the handle (16) and supports the headlight (31). The second support section (45) is fixed to the handle (16) and supports the headlight (31) on a lower side than the first support section (44).
