Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag attachment systems for motorcycles are not user-friendly, often requiring special tools for assembly and disassembly, are not adaptable to different motorcycle models, and compromise aesthetics and passenger comfort due to bulky designs.
Innovation Solution
A U-shaped tubular device with rotatable plate-like hooking means that can be easily mounted on various motorcycle structures without additional accessories, ensuring secure and stable bag attachment while allowing easy assembly and disassembly, and maintaining aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure and stable attachment system is used to prevent bag release during vehicle movement, then safety and stability are improved, but assembly and disassembly become complex and time-consuming, requiring special tools
Solution Approach 1:
The device employs a dynamic coupling mechanism where the coupling element can rotate between locked and unlocked positions. The rotatable connection allows the system to transition between secure attachment state and easy removal state, resolving the contradiction between secure attachment and simple operation.
Solution Approach 2:
The coupling system is designed to be self-servicing through its inherent mechanical properties. The rotatable coupling element automatically locks into position during attachment and can be easily released by simple rotation, eliminating the need for external tools or complex assembly procedures while maintaining secure attachment.
2Reliability
If a rigid and bulky bag design is used to ensure secure attachment, then stability is improved, but aesthetics are compromised and passenger movement is restricted
Solution Approach 1:
The invention enables the use of soft, flexible bag materials instead of rigid structures. The improved coupling device provides sufficient attachment security with soft bags, allowing these bags to maintain their aesthetic appearance and flexibility while still ensuring stable attachment during vehicle movement.
3Reliability
If a model-specific coupling system is used to achieve secure attachment, then reliability is improved, but adaptability to different motorcycle models is reduced
Solution Approach 1:
The coupling device is designed with universal adaptability to fit different motorcycle models and frame structures. The mounting structure can be configured to attach to various frame geometries, and the coupling element works with different bag types, making the system universally applicable across multiple motorcycle models while maintaining secure attachment.
4Reliability
If a complex coupling system with multiple components is used to ensure secure attachment, then stability is improved, but device complexity increases
Solution Approach 1:
The invention merges the mounting structure and coupling element into an integrated device. The mounting structure with adjustable arms and the rotatable coupling element work as a unified system, reducing the number of separate components while maintaining secure attachment capabilities. This integration simplifies the overall device structure compared to multi-component systems.

AI summary
A device (1) for hooking a bag to a fixed rear structure of a motorcycle, comprising a rigid, U-shaped, tubular body (11) intended to be inserted in a special pocket of said bag, wherein said tubular body (11) is provided at each end with anchoring means (12, 13) ending with a plate-like body (14, 15) intended to be constrained to said fixed rear structure, each plate-like body (14, 15) being joined to an end of said tubular body (11) by means of a joint (16, 17) so that each plate-like body (14, 15) may freely rotate on a plane substantially parallel to the plane on which said tubular body (11) lies.
