Adjustable Motorcycle Backrest Mounting for Comfort and Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle backrests lack adjustability and compatibility with various types, failing to provide adequate comfort and support for riders, as they are not height or angularly adjustable and cannot accommodate different backrest designs without removal of mounting plates.
Innovation Solution
A motorcycle backrest assembly featuring side plates with serrated adjustment discs and receivers that allow for angular and height adjustments, enabling easy installation and removal, and compatibility with various backrest designs by using notches and release latches for secure mounting on the fender, along with height-adjustment fasteners and serrated annuli for precise angle fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed backrest design is used, then the structure is simple, but the rider comfort and support are insufficient
Solution Approach 1:
The backrest is designed with adjustable features including height adjustment through notches and angular adjustment through rotation, transforming a static fixed structure into a dynamic adjustable one. This allows the backrest to adapt to different rider preferences and positions, improving comfort while maintaining reasonable structural complexity through standardized adjustment mechanisms.
2Adaptability or versatility
If a single-type backrest is mounted, then the mounting system is simple, but the compatibility with various backrest designs is limited
Solution Approach 1:
The mounting system incorporates universal features including standardized notches for height adjustment, rotation capability for angular adjustment, and a standardized plate interface. These universal design elements enable different types of backrests to be mounted on the same base plates without modification, achieving multi-functionality and broad compatibility while keeping the mounting system relatively simple.
3Ease of operation
If the backrest is permanently fixed, then the installation is secure, but the ease of removal and storage is reduced
Solution Approach 1:
The mounting system employs a dynamic quick-release mechanism using spring-loaded pins that can be easily actuated to release the backrest from the base plates. This allows the backrest to be securely mounted during use (providing reliability) while enabling rapid removal and storage when needed (providing ease of operation), transforming a permanent fixed connection into a controllable temporary connection.

AI summary
A motorcycle backrest assembly includes a pair of side plates each for mounting on either the left or right side of the motorcycle's rear fender. A receiver is securable to each plate for adjustably receiving one of two side rails depending from a backrest. Each receiver is angularly adjustable to vary the position of the backrest. The entire assembly can be quickly removed from the motorcycle and stored, if desired.
