Motorcycle Bag Fastening System with Universal Mounting Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for motorcycles are inadequate as they do not securely fasten bags or top-boxes to both central and lateral tubular structures, and require replacement of the entire system when changing top-box models, especially when the support plate is in a vertical position.
Innovation Solution
A fastening system comprising a plate and counter-plate with fastening teeth and a closure device that allows secure attachment to both central and lateral support structures, enabling easy replacement of bags or top-boxes without replacing the entire system, using a lock mechanism for secure detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a support plate is fixed to the lateral tubular luggage rack structure, then it can support lateral bags, but the plate cannot be securely fastened to the tubular structure and provides insufficient fastening stability
Solution Approach 1:
The fastening system is divided into separate functional components: a support plate for mounting bags, a mounting bracket that interfaces with the tubular structure, and a locking mechanism. This segmentation allows each component to be optimized for its specific function while maintaining overall system versatility and reliability.
Solution Approach 2:
The mounting bracket is designed with universal compatibility to interface with both central luggage racks and lateral tubular structures. The bracket's design incorporates adjustable features and multiple mounting configurations, allowing the same support plate assembly to be securely fastened to different support structures throughout the motorcycle.
2Adaptability or versatility
If the support plate is positioned vertically on the lateral tubular rack, then it can accommodate lateral bags, but conventional fastening systems cannot securely detach bags from the vertical plate position
Solution Approach 1:
The locking mechanism incorporates dynamic elements that adapt to the vertical plate orientation. The release lever and locking pins are positioned and oriented to allow easy manual operation regardless of the plate's vertical mounting position, enabling convenient bag attachment and detachment.
3Reliability
If the support plate is specifically designed for a particular top-box model, then it provides secure fastening for that model, but the entire fastening system must be replaced when changing top-box models
Solution Approach 1:
The system separates the bag-specific counter-plate from the motorcycle-mounted support plate and mounting bracket. This segmentation allows the counter-plate to be changed with different bag models while the support plate and mounting bracket remain fixed on the motorcycle, eliminating the need to replace the entire fastening system.
Solution Approach 2:
The support plate and mounting bracket are designed with universal mounting capabilities that can accommodate multiple bag and top-box models. The standardized interface and adjustable features allow different bags to be mounted on the same support structure without requiring system replacement.
4Adaptability or versatility
If conventional fastening systems are used on the lateral tubular rack, then they can fasten bags, but they do not provide sufficient fastening stability when the bag is hung from the plate
Solution Approach 1:
The mounting bracket incorporates curved or angled surfaces that conform to the circular cross-section of the tubular luggage rack. This curved interface design maximizes contact area and mechanical interlocking, providing superior fastening stability for hung bags compared to flat-plate conventional systems.
Solution Approach 2:
The mounting bracket is pre-installed and securely fastened to the tubular structure before bag attachment. This preliminary secure mounting ensures that the support structure is already stabilized and capable of bearing the bag's weight and dynamic loads during motorcycle operation.

AI summary
The present invention relates to a fastening system (10) for fastening a bag (1) or a top-box to a support structure (6, 7) integrally connected to a motorcycle. The fastening system according to the present invention allows to fasten a rigid or soft motorcycle bag or a top-box indifferently to the rack structure positioned posteriorly to the saddle of the motorcycle, or to the luggage rack structure, in general consisting of a tubular structure, positioned laterally to the vehicle, providing a simple and effective system for fastening a motorcycle bag indifferently to one or to the other support structure. Especially in the case of a bag "hung" from the lateral luggage rack structure, the proposed solution offers a stable fastening and at the same time allows to easily remove the bag from the vehicle.
