Stuffed Character Sleeping Bag With Upright Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sleeping bags for children lack functionality when not in use, as they do not provide entertainment or stability in an upright position without external support.
Innovation Solution
A sleeping bag system designed to resemble a stuffed character, featuring a torso with compartments for limbs and a removable item for stability, allowing it to sit upright when not in use, utilizing flexible materials and hook-and-loop connectors for structure and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sleeping bags are designed to be rolled up for storage, then storage convenience is improved, but entertainment value and visual appeal when not in use deteriorate
Solution Approach 1:
The sleeping bag is designed to serve multiple functions: it can be used as a sleeping bag and also transforms into a stuffed animal character for entertainment. The character configuration includes a head, torso, and limbs that can be positioned to create an upright sitting posture, providing visual appeal and entertainment value when not in use as sleeping bag.
Solution Approach 2:
The sleeping bag incorporates movable and adjustable components including a tiltable head, positionable limbs with connectors, and adjustable torso positioning. These dynamic elements allow the sleeping bag to transition between sleeping bag mode and stuffed animal mode, and to maintain various positions including an upright sitting posture without external support.
2Ease of operation
If sleeping bags are made soft and flexible for comfort, then sleeping comfort is improved, but ability to sit upright without support deteriorates
Solution Approach 1:
The sleeping bag incorporates different material properties in different regions: soft and flexible materials are used in the interior and lining for sleeping comfort, while the exterior shell and structural components use more rigid or supportive materials to provide structural integrity and enable upright positioning. The limbs and head incorporate connectors and positioning mechanisms that provide localized structural support.
Solution Approach 2:
The sleeping bag uses adjustable positioning mechanisms including connectors in the limbs, a tiltable head with positioning capability, and an adjustable torso that can be positioned to achieve and maintain an upright sitting posture. These dynamic structural elements allow the soft sleeping bag to gain temporary structural support when configured as a stuffed animal.
3Ease of manufacture
If sleeping bags are designed with simple ornamentation, then manufacturing complexity is reduced, but attractiveness and entertainment value deteriorate
Solution Approach 1:
The sleeping bag is designed to transform into a stuffed animal character, providing dual functionality as both sleeping bag and entertainment toy. This multi-functionality enhances attractiveness and entertainment value without requiring separate ornamental additions, as the character itself becomes the ornamentation through its configuration and positioning capabilities.

AI summary
A sleeping bag system has the appearance of a stuffed character when not in use as a sleeping bag and includes a torso including a torso compartment therein, a first limb having a first arm compartment therein which is in connection with the torso compartment, a second limb having a second arm compartment therein which is in connection with the torso compartment, at least a third limb having at least a first leg compartment therein which is in connection with the torso compartment. The sleeping bag system further includes an opening in the torso providing access to the torso compartment from outside of the sleeping bag system and an item removably storable in the torso compartment which is adapted to provide stability to the sleeping bag system such that the sleeping bag system can sit upright without support when not in use as a sleeping bag.
