Adjustable Accessory Mount for Motorcycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle accessory mounting systems lack a secure and adjustable mechanism to accommodate various detachable accessories, leading to potential vibration and rattling during operation due to loose fits.
Innovation Solution
The implementation of a pair of docking structures with adjustable hollow fittings that can be rotated and repositioned on lugs secured to the motorcycle frame, providing a non-circular docking surface with adjustable flanges to ensure a tight and secure fit for different accessory widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple fixed mounting brackets are used, then quick and easy detaching is achieved, but secure and adjustable fit is lost leading to vibration and rattling
Solution Approach 1:
The mounting system transitions from fixed brackets to adjustable fittings that can be rotated and repositioned. The fitting includes a body that rotates on the lug and flanges that can be repositioned axially, allowing dynamic adjustment to achieve secure fit while maintaining ease of attachment and detachment.
Solution Approach 2:
The system allows changing of mounting parameters including the rotational orientation of the fitting body on the lug, the axial position of flanges on the body, and the selection of different flange thicknesses. These parameter changes enable adaptation to different accessory widths and mounting requirements while maintaining secure attachment.
2Adaptability or versatility
If adjustable fittings with multiple orientations are used, then adaptability to various accessory widths is achieved, but device complexity increases
Solution Approach 1:
The fitting assembly serves multiple functions: the body provides rotational adjustment for angular orientation, the flanges provide axial positioning and width adaptation, and the entire assembly can be attached to or detached from the lug. This multi-functionality in a single integrated component achieves versatility without proportionally increasing complexity.
Solution Approach 2:
The mounting system is divided into separable components: the lug secured to the frame, the fitting body that rotates on the lug, and the flanges that can be repositioned axially. This segmentation allows independent adjustment of each component to achieve the desired configuration while simplifying manufacturing and assembly.

AI summary
A motorcycle includes a frame, a rear fender coupled to a rear portion of the frame, an accessory support structure and a pair of docking structures. The frame defines a longitudinal center axis, the motorcycle having left and right sides divided by the longitudinal axis. The accessory support structure is positioned laterally adjacent to both left and right sides of the rear fender. The pair of docking structures each includes a lug secured to the frame and extending transverse to the longitudinal center axis, and a hollow fitting positionable on the lug in a plurality of different rotational orientations about a mutual axis of the lug and the fitting. The fitting defines a docking surface with a non-circular cross-section. Lateral offset of the docking surface may be adjustable by reversing the fitting on the lug.
