Convertible Hooded Jacket With Contoured Sleeping Bag Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor jackets with convertible sleeping bags are bulky, heavy, and inefficient in retaining body heat due to excess empty space, which compromises warmth and convenience during extended outdoor activities.
Innovation Solution
A jacket design featuring a contoured lower pouch that fits the user's body shape, with foot recesses reducing internal volume and using securement means like clips, snaps, or hook and loop fasteners to store the sleeping bag within the jacket, allowing for easy deployment and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional sleeping bag is carried separately in a backpack, then thermal protection and comfort are provided, but weight and bulk increase substantially
Solution Approach 1:
The patent combines the jacket and sleeping bag into a single integrated garment. The sleeping bag is stored within the jacket's lower pouch portion, allowing the user to carry both items simultaneously without the need for separate backpack storage, thereby reducing overall weight and bulk while maintaining thermal protection functionality.
2Temperature
If a conventional sleeping bag is stored in a backpack, then it is protected during transport, but volume is consumed and accessibility is reduced
Solution Approach 1:
The sleeping bag is nested within the jacket's lower pouch portion, similar to a nested doll structure. This allows the sleeping bag to be stored compactly within the jacket's existing volume rather than requiring separate backpack space, optimizing storage efficiency and reducing overall gear volume.
3Ease of operation
If a sleeping bag is designed with substantial volume for comfort, then user comfort is improved, but portability and ease of transport are compromised
Solution Approach 1:
The sleeping bag is designed to be dynamically deployable from the jacket's lower pouch. When not in use, it is compacted within the pouch for easy portability; when needed, it can be quickly unfolded and extended to provide full sleeping bag comfort. This dynamic transformation allows the same structure to serve both portability and comfort requirements.
4Temperature
If a jacket converts into a sleeping bag with traditional design, then thermal protection is provided, but empty space reduces heat retention efficiency
Solution Approach 1:
The sleeping bag portion is designed with contoured lower sections that fit the user's body shape, reducing unnecessary empty space in critical areas while maintaining adequate volume for comfort. This localized optimization of volume distribution improves heat retention efficiency by minimizing cold air pockets in regions where the user's body would normally be positioned.

AI summary
Described is a wearable garment that converts into a sleeping bag for insulating a user from environmental elements. The garment includes a hooded jacket having two side portions covering a user's chest, a rear portion covering a user's back, two arm portions and a jacket hood. A lower pouch is removably secured at the bottom of the jacket and folds up to lie flat against the interior of the rear portion and jacket hood. This lower pouch is a recess contoured to fit the shape of a human lower body and having two feet shaped recesses at the bottom. By contouring the lower body enclosure to fit the shape of the legs and feet, excess air space is eliminated and overall insulation is improved. In this way the device provides a user with an easy to carry, non-cumbersome sleeping bag that protects the user from the outdoors and cold environments.
