Motorcycle Mirror Support with Integrated Wiring Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirror devices for saddle-ride or straddle-type vehicles, such as motorcycles, face challenges in achieving high rigidity and waterproofness while minimizing the number of components and avoiding exposure of wiring, which can lead to damage and design issues.
Innovation Solution
A mirror device with a support member that has an integral inner passage from one end to the other, featuring a holding mechanism with a rivet member and fixing members that allow for rotational support and secure attachment to the vehicle, preventing water ingress and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the front housing and rear housing are joined by engagement between multiple engaging holes and engaging claws, then the number of fastening members is reduced, but the rigidity of the housing is insufficient
Solution Approach 1:
The patent merges the front housing and rear housing into a single integrated housing structure. This eliminates the need for multiple engaging holes and claws, providing sufficient rigidity while reducing the number of fastening members required for assembly.
2Ease of manufacture
If wiring is provided in the space between the cover and attachment stay, then connection is achieved, but waterproofness is compromised due to gaps at the housing boundary
Solution Approach 1:
The patent introduces a waterproof grommet as an intermediary component through which the wiring passes. This grommet seals the opening in the attachment stay, preventing water ingress while allowing the wiring to pass through the housing boundary.
3Strength
If multiple components are used to achieve high rigidity and waterproofness, then performance is improved, but the number of components increases
Solution Approach 1:
The patent combines multiple functions into the attachment stay component, which serves as both a structural support element and a waterproofing element with an integrated grommet. This reduces the total number of components while maintaining high rigidity and waterproofness.
4Ease of manufacture
If wiring is exposed between components, then connection is achieved, but the wiring is vulnerable to damage and design appearance is degraded
Solution Approach 1:
The patent nests the wiring inside the integrated housing structure, with the wiring passing through the waterproof grommet in the attachment stay. This protects the wiring from external damage while maintaining design appearance, as the wiring is concealed within the housing rather than being exposed.

AI summary
One end of a support member (44) is coupled to a holding member (43) that holds a mirror and an indicator or flasher. The other end of the support member (44) is rotatably attached to a vehicle main body (200) by a movable holding mechanism (45). The support member (44) has an inner passage (44p) that extends from the one end to the other end. A lower end of a rivet pin is crimped in a state in which a vehicle fixing member is arranged such that a flange of the rivet pin is located between the other end of the support member (44) and a pin fixing member and surrounds an outer periphery of the rivet pin between the pin fixing member and the lower end of the rivet pin. Wiring of the indicator or flasher is led to the vehicle main body (200) through the inner passage (44p) and a through passage of the rivet pin.
