Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders of motorcycles face discomfort and safety issues when wearing over-the-shoulder strapped bags or purses while riding, as these can be cumbersome and dangerous.
Innovation Solution
A bag or backpack with straps that can be securely attached to a motorcycle's seatback or sissy bar using VELCRO fasteners, allowing easy attachment and detachment, enabling the bag to be transferred between the seatback and the rider, or between motorcycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If riders wear over-the-shoulder strapped bags or purses while riding, then they can carry bags, but the bags become uncomfortable and cumbersome
Solution Approach 1:
The patent introduces a motorcycle seatback as an intermediary carrier between the rider and the bag. The bag is attached to the seatback via straps that wrap around the seatback structure, transferring the burden from the rider's shoulders to the motorcycle's seatback, thereby eliminating discomfort and safety issues associated with worn bags
2Adaptability or versatility
If riders use permanently mounted compartments or bags on the motorcycle, then bags can be carried, but the bags cannot be easily removed or transferred
Solution Approach 1:
The patent employs dynamic attachment mechanisms including adjustable straps with buckles and Velcro® fasteners that allow the bag to be easily attached and detached. The straps can be quickly fastened around the seatback and released when needed, enabling the bag to be transferred between motorcycles or carried by the rider, thus providing both security and versatility
Solution Approach 2:
The bag system is divided into separable components: the bag body and the attachment straps. The straps are connected to the bag body at upper and lower connection points, allowing the bag to be detached from the straps and carried separately, providing flexibility in usage scenarios
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure, comfortable, and fashionable way to carry bags while riding, eliminating the discomfort and safety risks associated with over-the-shoulder straps, and allowing easy transfer between vehicles.
Implementation Method 1
The bag and strap connectors are comprised of VELCRO fasteners

AI summary
A bag that can be releasably attached to and detached from a seatback having at least one supporting post is disclosed. It includes a bag body having a top and bottom, and a pair of straps disposed laterally with respect to each other on the bag body. Each of the straps is connected to the bag body at an upper connection point near the top, and a lower connection point near the bottom. A zipper is provided for selectively connecting and separating the straps from each other, by selectively zipping and unzipping the zipper. At least one bag connector is disposed on the bag near the bottom, and a strap connector is disposed on at least one of the straps at a point closer to the lower connection point than the upper connection point. The bag connector and strap connector are adapted to be releasably connected to each other. The bag is configured to be attached to the seatback by wrapping the straps around the seatback, zipping the straps together, and applying the strap connector to the bag connector around the at least one supporting post, to thereby trap the supporting post between the bag connector and the lower connection point.
