Convertible Sleeping Bag Pouch Layout for Easier Backpack Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing convertible sleeping bags are overly complex and difficult to transform from a sleeping bag into a backpack, making them cumbersome for use.
Innovation Solution
A sleeping bag design featuring a flexible pouch attached to the lower end with shoulder straps and a side attachment assembly, allowing for easy conversion by folding along a central axis and securing within the pouch, with quick-release fasteners and a drawstring for closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sleeping bag is configured with a pouch and shoulder straps to enable conversion into a backpack, then the sleeping bag can be used for transport without a separate backpack, but the conversion process becomes unduly difficult and complex
Solution Approach 1:
The sleeping bag is divided into functional segments: the main bag body, an integrated pouch section, and detachable shoulder straps. The side edges are designed with specific attachment mechanisms that allow the bag to be folded and secured in a backpack configuration. This segmentation enables the sleeping bag to transform from a single-use item into a multi-functional packable backpack system.
Solution Approach 2:
The pouch is merged directly into the sleeping bag structure rather than being a separate component. The shoulder straps are integrated with the bag at specific locations. This merging creates a unified convertible system where the sleeping bag itself becomes the backpack container, eliminating the need for separate carrying equipment.
2Adaptability or versatility
If the sleeping bag includes integrated pouch and shoulder straps for backpack conversion, then separate backpack equipment is eliminated, but the overall device complexity increases
Solution Approach 1:
The sleeping bag is designed to serve multiple functions: it can be used as a traditional sleeping bag, folded into a cylindrical pouch for storage, or converted into a wearable backpack. The same structural elements (pouch, straps, side attachments) enable these different modes of use, maximizing the utility of a single device without requiring multiple separate items.
Solution Approach 2:
The sleeping bag incorporates dynamic elements including detachable shoulder straps that can be attached or removed as needed, and side attachments that can be fastened or unfastened to enable or disable the backpack configuration. This dynamic design allows the structure to adapt to different usage scenarios without permanent complex modifications.

AI summary
This invention provides an improved sleeping bag convertible into a backpack with reduced complexity and greater ease of use. The sleeping bag includes (1) an elongated flexible bag; (2) a flexible pouch attached to the bag at or near the bag's lower end; (3) left and right shoulder straps, each having a lower section attached to the bag at the bag's lower end and an upper section attached to the bag at a location spaced from the bag's lower end; and (4) a side attachment assembly for releasably attaching the left side edge of the bag to the right side of the bag, adjacent to the pouch. The bag is configured to be storable within the pouch by (a) folding the bag along a central longitudinal axis, (b) folding the bag lengthwise into the pouch via the pouch's open upper end, and (c) attaching the side attachment assembly, after which the sleeping bag can be worn as a backpack on a person's shoulders.
