Motorcycle Supplemental Mirror Assembly for Expanded Rear View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycle operators face challenges in obtaining an undistorted rear view due to the lack of a rearview mirror, relying on compromised adjustments of side view mirrors which can distort the view.
Innovation Solution
A supplemental side mirror assembly is designed to be positioned above the primary side mirror on a motorcycle, comprising a mirror, a shell, an arm, and clamp members that securely attach to the motorcycle's side view mirror support arm, providing an expanded, undistorted field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a motorcycle uses only side view mirrors for rear viewing, then the device complexity is reduced, but the measurement precision of rear view is compromised due to distorted images
Solution Approach 1:
The mirror system is segmented into multiple components: a primary side view mirror and a supplemental mirror assembly. The supplemental assembly divides further into a housing, arm mechanism, and adjustable mirror element. This segmentation allows each component to perform its specific function - the primary mirror for side viewing and the supplemental mirror for rear viewing - thereby improving rear view accuracy without significantly increasing overall system complexity.
Solution Approach 2:
The invention adds a new dimensional aspect to the mirror system by positioning the supplemental mirror above the primary side view mirror, creating a vertical arrangement. This dimensional change enables the supplemental mirror to capture rearward views that are not visible to the primary mirror, thereby improving rear view accuracy while maintaining a compact lateral profile.
2Area of stationary object
If a supplemental mirror is added above the primary side mirror, then the field of view is expanded, but the device complexity increases due to additional components
Solution Approach 1:
The supplemental mirror assembly is designed with multi-functionality to reduce overall complexity. The adjustable arm mechanism serves multiple purposes: positioning the mirror at the correct angle, allowing height adjustment, and enabling angular orientation changes. The housing structure provides both mounting functionality and structural support. This multi-functionality means that while additional components are present, each component performs multiple tasks, thereby limiting the net increase in system complexity.
Solution Approach 2:
The mirror assembly employs a nested structure where the mirror element is housed within the housing, which in turn is mounted on the arm mechanism, which is attached to the primary mirror assembly. This nesting arrangement consolidates multiple components into a compact package, minimizing the space required and reducing the apparent complexity of the overall system while still providing the expanded field of view.
3Adaptability or versatility
If the supplemental mirror is made adjustable, then the adaptability to different viewing angles is improved, but the ease of operation is reduced due to adjustment mechanisms
Solution Approach 1:
The arm mechanism incorporating the supplemental mirror is designed with dynamic adjustment capabilities, allowing the mirror to be repositioned in multiple directions. The arm can be angled relative to the housing, and the housing itself can be oriented at different angles. This dynamic adjustability provides superior viewing angle adaptability. The mechanisms are designed to be manually adjustable, balancing the trade-off between adaptability and ease of operation by providing sufficient flexibility without overly complex adjustment procedures.

AI summary
A supplemental side mirror assembly for a motorcycle includes a mirror, a shell attached to the mirror, and an arm attached to the shell. The arm is positioned to extend away from the shell. A base is coupled to a free end of the arm. A first clamp member is coupled to the base. The first clamp member is C-shaped. A second clamp member is detachably coupled to the first clamp member. The second clamp member is C-shaped such that the first clamp member and the second clamp member together define a cylindrical passage when coupled together. The first clamp member and the second clamp member are designed to be clamped onto a support arm of a side view mirror attached to a handlebar of a motorcycle, such that the mirror is positioned above the side view mirror of the motorcycle to provide an expanded field of view.
