Motorcycle Mirror Attachment for Easy External Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mirror devices in straddle-type vehicles, such as motorcycles, are difficult to disassemble due to screws being located in a closed space between the mirror and the housing, making it challenging to handle and disassemble the mirror device.
Innovation Solution
A mirror device design featuring a stay attached to the vehicle body, a housing supported on the stay, and a mirror mechanism with a holding portion accommodated in the housing, along with an attachment portion that allows for easy detachment and attachment operations, exposing the receiving portion outside the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the screw is located in a closed space between the mirror and the housing, then the mirror device achieves a compact structure, but it becomes difficult to handle and disassemble the mirror device
Solution Approach 1:
The receiving portion is extracted from the closed internal space and exposed to the outside through the attachment portion. This allows the screw to be accessed and operated from the exterior while maintaining the compact internal structure, resolving the contradiction between compactness and ease of disassembly
Solution Approach 2:
The attachment portion serves as an intermediary structure that connects the internal receiving portion to the external environment. It provides access to the screw without requiring disassembly of the housing, enabling easy maintenance while preserving the compact design
