Self-Stabilized Rollable Luggage Assembly with Adjustable Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luggage systems with wheels become cumbersome and difficult to maneuver, especially when transporting multiple large and heavy pieces, as they require both hands and can be challenging to navigate through tight spaces or up/down steps, limiting the user's ability to perform other tasks.
Innovation Solution
A self-stabilizing luggage assembly system that connects multiple luggage pieces using a deployable adjustable strap, allowing the majority of the weight to rest on wheels and providing stability and maneuverability with a single-hand operation, enabling easy navigation through obstacles and varying environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple wheeled luggage pieces are transported simultaneously, then the traveler can carry more belongings, but both hands are required making it difficult to perform other tasks
Solution Approach 1:
The patent combines multiple separate luggage pieces into a single integrated assembly by connecting them through handles and straps. The first luggage piece's handle serves as the primary control point, while the second luggage piece is attached via its handle to the first piece, creating a unified structure that can be maneuvered with one hand despite carrying multiple items.
2Stability of the object's composition
If both hands are used to hold multiple luggage pieces, then stability is maintained, but the traveler cannot answer calls or retrieve items from pockets
Solution Approach 1:
The luggage assembly is designed to be self-stabilizing through its structural configuration. The connection between luggage pieces via handles and straps creates a self-supporting structure that maintains stability without requiring continuous manual intervention. The assembly can remain upright and balanced even when the traveler releases their hand, enabling them to perform other tasks.
3Adaptability or versatility
If conventional luggage without connection systems is used, then each piece can be handled independently, but maneuvering through narrow spaces and up/down steps becomes difficult
Solution Approach 1:
The invention uses a segmented connection system where luggage pieces are linked through their handles and straps rather than being rigidly combined. This segmentation allows the assembly to flex and adapt to different terrains and obstacles. The connection points at the handles enable the structure to bend and adjust during maneuvers up stairs or through narrow spaces, combining the benefits of unified control with individual piece flexibility.

AI summary
A luggage assembly is disclosed that includes a first piece of luggage and a second piece of luggage. A variable length attachment member such as a strap forming a loop, is affixed to the second piece of luggage. The attachment member couples the second piece of luggage to the first piece of luggage to form an assembly, in which the first and second pieces of luggage are self-stabilized while upright and inclined, and while in motion and while stationary.
