Removable Motorcycle Seat Back with Foldable Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motorcycle seat backs are not adaptable for storage in small spaces, limiting their removal and reinstallation during a ride, forcing riders to decide beforehand whether to carry a second passenger with a seat back.
Innovation Solution
A removable motorcycle seat back design featuring a tubular steel frame with rotatable connection members that can be folded for easy storage, secured with spring-loaded pins and clips for safe and convenient handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the seat back uses a rigid frame structure, then it provides structural strength and stability, but it cannot be stored in small spaces like saddlebags
Solution Approach 1:
The seat back frame is divided into multiple segments including a backrest portion, a base portion, and connection members that can be folded relative to each other. This segmentation allows the rigid frame to be collapsed into a compact configuration for storage while maintaining structural integrity when assembled
Solution Approach 2:
The frame incorporates dynamic elements such as rotatable connection members with spring-loaded pins that allow the rigid structure to transition between extended (for use) and folded (for storage) states. The spring-loaded mechanism provides controlled movement while maintaining structural strength during operation
2Adaptability or versatility
If the seat back is permanently attached to the motorcycle, then it is always available for passenger comfort, but it cannot be removed for aesthetic reasons or when riding solo
Solution Approach 1:
The seat back is designed as a separable assembly with distinct components (backrest, base, connection members) that can be easily detached from the motorcycle. The connection members feature simplified attachment mechanisms that enable quick removal and reinstallation without permanent mounting
Solution Approach 2:
The connection members incorporate spring-loaded pins and rotatable joints that facilitate easy attachment and detachment. These dynamic connection elements allow the seat back to be quickly installed or removed based on riding conditions while maintaining secure attachment when in use
3Stability of the object's composition
If the seat back is made rigid for structural stability, then it provides reliable support, but it cannot be folded for easy storage
Solution Approach 1:
The rigid frame is segmented into multiple rigid components (backrest portion, base portion, connection members) connected by articulated joints. Each segment maintains its structural rigidity while the connections allow folding, enabling the stable support function during use and compact storage when folded

AI summary
An improved removable seat back for a motorcycle including a cushion, a frame, the frame including an upper portion secured to the cushion and a lower portion having a pair of frame supports, and a pair of frame connection members. Each of the frame connection members includes a connection member upper portion and a connection member lower portion. The connection member upper portion is preferably rotatably secured to one of the frame supports with a pin and slot arrangement and the connection member lower portion generally includes a first securement point and a second securement point where at least one of the securement points is preferably a groove and one preferably includes a clip. When no longer needed, the seat back is removed by disconnecting the frame connection members from the motorcycle, rotating them and storing them in a saddlebag.
