Folding Rolling Bag with Segmented Aluminum Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling bags lack a compact and efficient mechanism for storing and transporting folding structures, such as canopies, as they often require separate support systems for rigidity and mobility, which can be cumbersome and inefficient.
Innovation Solution
A folding structure rolling bag with a non-rigid bag portion and a rigid frame portion, featuring a lengthwise zipper and a socket channel system that integrates wheels and a horizontal frame for support, allowing the bag to fold and unfold while providing mobility and storage capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid frame is used to provide structural support for the rolling bag, then the bag gains stability and mobility, but the storage compactness is reduced
Solution Approach 1:
The rigid frame is segmented into collapsible sections that can be folded into a compact configuration. The frame consists of multiple interconnected segments that can be collapsed along predetermined lines, allowing the structure to transition from an extended stable state to a compressed compact state for storage.
Solution Approach 2:
The folding structure is nested within the bag portion when collapsed. The rigid frame segments are designed to fold inward and nest within the bag's volume, with the vertical frame portion folding toward the horizontal frame portion, maximizing space utilization and minimizing storage volume.
2Volume of moving object
If a non-rigid bag portion is used to achieve flexibility and compact storage, then the storage compactness is improved, but the structural support is reduced
Solution Approach 1:
The non-rigid bag portion and rigid frame portion are merged into a unified structure where the bag is attached to the frame. The bag portion provides flexibility and cushioning while the integrated rigid frame provides structural support, creating a hybrid construction that combines the advantages of both rigid and flexible materials.
Solution Approach 2:
The rolling bag employs a composite construction combining flexible bag material (fabric or polymer) with rigid frame material (metal or rigid plastic). This composite structure allows the bag portion to remain flexible for compact storage while the integrated frame portions provide the necessary structural strength and rigidity for support and mobility.
3Stability of the object's composition
If separate support systems are used for rigidity and mobility, then the structural support is improved, but the device complexity is increased
Solution Approach 1:
The support system and mobility system are merged into a single integrated frame structure. The rigid frame portions simultaneously provide structural support for the bag and serve as the mounting structure for the wheels, eliminating the need for separate support systems and reducing overall device complexity.
Solution Approach 2:
The rigid frame portions serve multiple functions: providing structural support for the bag, enabling mobility through wheel attachment, and facilitating folding for compact storage. This multi-functional design eliminates the need for separate dedicated components for each function, thereby reducing system complexity.

AI summary
A folding structure rolling bag has a bag portion. The bag is not rigid and a lengthwise zipper opens along a length of the bag portion. The folding structure rolling bag also has a frame portion. The frame is rigid and includes a right wheel axle holding a right wheel and a left wheel axle holding a left wheel. The frame portion includes a vertical frame portion and a horizontal frame portion. The vertical frame portion extends no more than a quarter of a length of the bag portion. The frame portion is an aluminum extrusion. The lengthwise zipper extends from a rear bag opening to a front cover, and the front cover is configured to cover a folding structure.
