Combination stuffed character and sleeping bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sleeping bags for children lack an engaging and functional design when not in use, failing to 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 deteriorates
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 toy for entertainment. The body portion forms the main body of the stuffed animal, limbs become arms and legs, and the hood becomes a head with facial features, allowing the same object to provide both sleeping functionality and entertainment value.
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:
Different portions of the sleeping bag have different structural properties tailored to their specific functions. The body portion and limbs are made soft and flexible for sleeping comfort, while the bottom portion is designed with enhanced stability features including a widened base and optional weighting elements to provide structural support for upright positioning. This local differentiation allows the sleeping bag to be comfortable for sleeping while maintaining stability when positioned upright as a stuffed animal.
3Ease of manufacture
If sleeping bags are designed with simple ornamentation, then manufacturing simplicity is improved, but visual appeal and character recognition deteriorates
Solution Approach 1:
The design merges the sleeping bag structure with the stuffed animal form factor, where the functional elements of the sleeping bag (body, limbs, hood) directly become the structural elements of the stuffed animal. Simple ornamentation such as embroidered facial features, painted eyes, and basic color patterns are applied to transform the sleeping bag into a recognizable character without requiring complex additional components or manufacturing steps.

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.
