Headlamp Support via Elastic Stopper Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlamp supporting structures for saddle-type vehicles require significant changes and increased costs when a new design is implemented, as they necessitate the addition of a projection at the rear of the headlamp and a corresponding change in the supporting frame, even for minor design updates.
Innovation Solution
A headlamp supporting structure that uses a stopper bracket mounted on the headlamp's lower portion, elastically supported by a cowl stay, allowing the headlamp to be attached without a projecting cowl stay, facilitating easy positioning and attachment, and utilizing the space between headlamps for other components like a vacuum tank, thus minimizing structural changes and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a projection is provided at the rear portion of the headlamp housing to engage with the cowl stay, then the headlamp can be supported on the cowl stay, but significant changes are required in both the headlamp and supporting frame when a new design is created, resulting in increased cost
Solution Approach 1:
A stopper bracket is introduced as an intermediary component between the headlamp housing and the cowl stay. The stopper bracket is mounted on the lower portion of the headlamp housing and engages with the cowl stay, providing the necessary support function without requiring modifications to the headlamp housing itself. This mediator allows the headlamp to be supported while maintaining design flexibility.
Solution Approach 2:
The supporting function is segmented from the headlamp housing into a separate stopper bracket component. This segmentation allows the headlamp housing to remain unchanged for design updates while the stopper bracket can be independently modified or replaced, reducing the impact of design changes on overall cost.
2Stability of the object's composition
If the headlamp is supported at the outer periphery by the front cowl and at the rear portion by a projection engaging with the cowl stay, then the headlamp is stably supported, but the supporting structure becomes complex requiring multiple attachment points and structural elements
Solution Approach 1:
The stopper bracket combines multiple functions into a single component: it provides the engagement point with the cowl stay, offers elastic support through the integrated elastic body, and serves as a mounting structure for the headlamp. This merging simplifies the overall supporting structure while maintaining stability.
Solution Approach 2:
The stopper bracket serves multiple purposes: it acts as a support element, a positioning element, and an attachment point for the elastic body. This multi-functionality reduces the need for separate components and simplifies the supporting structure.

Function Achieved in This Case
This configuration allows for minor adjustments to the headlamp and cowl stay, reducing costs and simplifying the supporting structure while ensuring stable and balanced support for paired headlamps, with improved positioning and reduced interference with other components.
Implementation Method 1
an elastic body (64) fitted with the stopper bracket (72) is mounted on the cowl stay (51) and the headlamp (35) is elastically supported at the lower portion thereof by the cowl stay (51) through the elastic body (64)

AI summary
To achieve, in a headlamp supporting structure for a saddle type vehicle for supporting a headlamp on a front cowl and a cowl stay, reduction of the cost with little change of a headlamp and a supporting structure for the headlamp also upon change of a headlamp. An outer periphery of a headlamp (35) is attached to a front cowl (34), and a stopper bracket (72) is attached to a lower portion of the headlamp (35). An elastic body (64) for fitting with the stopper bracket (72) is attached to a supporting piece (55) of a cowl stay, and the headlamp (35) is elastically supported at a lower portion thereof by the supporting piece (55) of the cowl stay through the elastic body (64).
