Motorcycle Saddlebag with Flexible Intermediate Part for Volume Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle saddlebags face issues with fixed volume, leading to rattling and instability due to non-adjustable capacity, and alternative luggage containers lack stiffness and theft protection.
Innovation Solution
A motorcycle saddlebag design featuring a flexible intermediate part between interior and exterior parts, allowing volume adjustment with tension elements and reinforced materials for stability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed volume saddlebag is used, then the structure is simple and stable, but the load volume cannot be adapted to actual needs causing rattling and instability
Solution Approach 1:
The patent applies the dynamics principle by making the saddlebag volume adjustable rather than fixed. The intermediate part can be folded or extended to change the internal volume, allowing the bag to adapt to different load sizes. This dynamic adjustment eliminates rattling when lightly loaded while maintaining structural integrity when fully loaded.
Solution Approach 2:
The saddlebag is segmented into three main parts: an interior part, an exterior part, and an intermediate part. The intermediate part acts as a flexible connector that can be folded or extended independently, enabling volume adjustment without compromising the overall structural stability of the bag.
2Adaptability or versatility
If a flexible luggage container is used, then volume can be adjusted, but stiffness and theft protection are reduced
Solution Approach 1:
The patent employs composite material principles by combining flexible elements (the foldable intermediate part) with rigid components (the interior and exterior parts). This composite structure allows volume adjustment through folding while the rigid outer shell maintains theft resistance and structural strength.
Solution Approach 2:
The intermediate part functions as a flexible shell that can be folded or extended to adjust volume. However, this flexible element is contained within a rigid exterior part that provides the necessary stiffness and theft protection, combining the benefits of both flexible and rigid structures.
3Loss of energy
If the saddlebag volume is reduced for minimal load, then air resistance decreases, but structural stability may be compromised
Solution Approach 1:
The saddlebag dynamically adjusts its volume by folding the intermediate part when lightly loaded, reducing air resistance. The rigid interior and exterior parts remain in place, maintaining structural stability even when the intermediate section is collapsed to minimize volume.

AI summary
Saddlebag for motorcycles, having a luggage interior part facing the motorcycle in the installed state, a luggage exterior part facing away from the motorcycle in the installed state and which is mounted for opening and closing the saddlebag so it can pivot with respect to the luggage interior part. A flexible luggage intermediate part is situated between the luggage interior part and the luggage exterior part.
