Auto-foldable Pouch with Nested Enclosing Portion and Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pouch enclosures are bulky when empty or partially filled, making them inconvenient to carry or store, and lack an auto-foldable design with a separate enclosing portion and fastener to securely hold items.
Innovation Solution
An auto-foldable pouch design that includes a separate enclosing portion and a fastener to securely hold items, allowing the pouch to auto-fold into a compact configuration, with options for carrying on the person or attaching to eyeglasses/sunglasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pouch enclosures are designed to hold portable items with opening and fastener, then items can be securely stored, but the pouch becomes bulky when empty or partially filled making it difficult to carry or store
Solution Approach 1:
The pouch is designed with dynamic foldability, transitioning from a flat compact state to a three-dimensional enclosed state only when needed. The auto-foldable structure allows the pouch to dynamically change its volume and shape based on usage requirements, being compact for carrying and fully expanded for storage.
Solution Approach 2:
The pouch structure is designed so that the enclosing portion can be nested within or along the auto-foldable portion when not in use. The fastening system allows layers to be nested together in a compact configuration, similar to nested dolls, minimizing the overall volume when the pouch is empty or partially filled.
2Volume of moving object
If auto-foldable material configurations are used to reduce bulk, then compactness is improved, but the pouch lacks a separate enclosing portion and fastener to securely hold items
Solution Approach 1:
The pouch is segmented into functionally distinct portions: an auto-foldable portion for achieving compactness, a separate enclosing portion for securing items, and a fastening system for closure. Each segment performs its specific function independently, allowing the pouch to be both compact and secure simultaneously.
Solution Approach 2:
The patent merges the auto-foldable material configuration with a separate enclosing structure and fastening system into a unified pouch design. The auto-foldable portion and enclosing portion are connected and work together, combining the benefits of compact auto-folding with secure item enclosure and fastening capabilities.
3Reliability
If pouch enclosure includes opening and fastener for secure closure, then item security is improved, but the structure becomes more complex and bulkier
Solution Approach 1:
The fastening system is designed to serve multiple functions: it secures the opening closure, enables the auto-foldable action, and contributes to the overall structural integrity. This multi-functionality reduces the need for separate components, simplifying the overall structure while maintaining security.
Solution Approach 2:
The pouch incorporates self-folding capabilities through its structural design, where the pouch automatically folds and compacts itself without requiring additional mechanisms or user intervention. The fastening system works in conjunction with the auto-foldable structure to achieve automatic compaction, reducing complexity.

AI summary
Implementations of an auto-foldable pouch are provided. In some implementations, the auto-foldable pouch comprises an auto-foldable portion and a closure portion that form a pouch enclosure that can receive and hold an item.In some implementations, a method of using the auto-foldable pouch comprises unrolling the pouch, opening the pouch, inserting one or more items into the pouch, and closing the pouch to securely hold and enclose the items.
