Meter Stay Support Structure for Saddled Vehicle Top Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional support structures for meter stays in saddled vehicles, particularly those with a steering handle fixed to the top bridge, face challenges in arranging space for elastic members to mitigate vibration, leading to complex and bulky designs.
Innovation Solution
A support structure that mounts the meter stay directly to the top bridge using a shaft member and elastic members, allowing for a floating mount configuration, which simplifies the design, reduces the number of parts, and minimizes the size of the top bridge by accommodating the elastic members within hemispherical enlarged diameter parts, eliminating the need for additional elastic members between the meter device and the meter stay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the meter stay is attached directly to the top bridge without a fork bracket, then the number of parts is reduced and the structure is simplified, but the arrangement space for elastic members becomes limited and the support structure becomes complicated
Solution Approach 1:
The patent combines the attachment functions for the handle clamp and meter stay into a single integrated structure on the top bridge. The shaft member extends downward from the handle clamp and passes through the top bridge to support both components, eliminating the need for separate fork bracket attachments and reducing overall structural complexity while maintaining adequate space for elastic members.
Solution Approach 2:
The elastic member is nested within a recess formed in the top bridge structure. This recess accommodates the elastic member between the shaft member and the top bridge surface, effectively utilizing the available vertical space without requiring additional lateral arrangement space, thus resolving the space limitation issue.
2Reliability
If the elastic member is arranged in the conventional manner with separate attachment points, then the vibration protection is effective, but the top bridge size increases and the appearance is compromised
Solution Approach 1:
The top bridge is designed with a localized recess specifically at the attachment point area to accommodate the elastic member. This recess creates the necessary space for vibration protection functionality without increasing the overall dimensions of the top bridge, as the elastic member is housed within the existing structural envelope rather than adding external bulk.
3Object-affected harmful factors
If additional elastic members are added between the meter device and meter stay, then the vibration suppression is improved, but the device complexity and number of parts increase
Solution Approach 1:
The single elastic member in the patent serves multiple functions simultaneously: it provides vibration suppression for both the handle clamp and meter stay attachments, acts as a mounting element, and accommodates misalignments. This multi-functional design eliminates the need for multiple separate elastic members while maintaining comprehensive vibration protection for all attached components.

Function Achieved in This Case
This configuration enhances design freedom, reduces the size and complexity of the top bridge, improves the appearance, and simplifies the assembly and positioning of the meter device, while maintaining effective vibration suppression.
Implementation Method 1
an elastic member (58a) is disposed to be in contact with a lower surface of the top bridge (5)... to protect the meter device from vibration

AI summary
A support structure for a meter stay applied to a saddled vehicle including a top bridge coupling upper ends of a left-right pair of front forks; a handle clamp supporting a steering handle above the top bridge; and a meter stay supporting a meter device, in which a shaft member extends downwardly and is positioned on a lower surface of the handle clamp; an elastic member is disposed to abut a lower surface of the top bridge; the meter stay is placed to be in contact with a lower surface of the elastic member; and the shaft member passes through the top bridge, the elastic member, and the meter stay in this order, with a fixing member being coupled to a distal end of the shaft member.
