Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luggage is difficult to compress and stack, leading to inefficient storage and transportation, and lacks a uniform size for easy display and handling.
Innovation Solution
Development of foldable duffle bags that can transform from a fully expanded state with usable wheels to a compressed state, allowing for maximal volume reduction and easy storage, featuring innovative folding mechanisms and hidden wheels for a compact, portable design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If luggage is designed with significant volume for storage capacity, then it can hold more items, but it occupies excessive storage space when not in use
Solution Approach 1:
The duffle bag employs dynamic structural elements including collapsible side panels, extendable handles, and retractable wheels that allow the bag to transition between expanded high-capacity state and compressed low-volume state, resolving the contradiction between storage capacity and storage space occupied
Solution Approach 2:
The bag's volume parameter is made variable through collapsible construction that allows compression to a fraction of its expanded size, enabling it to provide large storage capacity when needed while occupying minimal space during storage, directly addressing the technical contradiction
2Adaptability or versatility
If luggage pieces are of varying sizes to meet different storage needs, then they can accommodate different quantities of items, but they cannot stack uniformly and create unstable piles
Solution Approach 1:
The duffle bag is designed with universal dimensions in its compressed state that allow it to function both as a large-capacity bag when expanded and as a uniform stackable unit when compressed, enabling it to adapt to different storage needs while maintaining stacking stability
Solution Approach 2:
Multiple duffle bags can be nested within each other in their compressed uniform state, creating stable vertical arrangements that maintain both the adaptability for different storage capacities and the stacking stability for organized storage
3Quantity of substance
If luggage is designed with large volume for expanded state, then it provides adequate storage space, but it requires significant space for display in retail environments
Solution Approach 1:
The duffle bag's dynamic design allows it to be displayed in its compact compressed form occupying minimal retail display space, while still providing adequate storage capacity when expanded for customer use, resolving the contradiction between storage capacity and display space requirements
4Volume of stationary object
If luggage pieces are nested for compression during transportation, then space is saved, but significant work is required to take them apart on the receiving end
Solution Approach 1:
The duffle bag is segmented into collapsible panels and modular components that can be easily folded and compressed individually, allowing for simple nesting during transportation and equally simple unfolding and assembly at the destination, reducing both transportation volume and assembly effort

AI summary
In exemplary embodiments of the present invention, systems and methods for providing foldable duffle bags are presented. Such exemplary collapsible duffles can have two states: (i) a fully extended state in which said luggage is used by a user to hold, for example, clothing and objects, and its wheels fully extended and usable, and (ii) a compressed or folded state in which the luggage has a minimum volume and can be easily and conveniently stored and carried, especially where space is a premium, where the wheels are invisible and out of the way. Various novel technologies are used to obtain maximal compression in the compressed state, and to allow for convenient transformation between the two states. Exemplary duffles of rather significant fully expanded size can be rolled or folded onto themselves, the wheels can be turned inside out, and the article compressed into a small hand held carrying case.
