Multi-mode sleeping bag for children
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sleeping bags are not designed to meet the specific needs of young children or babies, as they may contain hazardous loose flaps or small articles, and do not ensure a safe sleeping position, which can increase the risk of sudden infant death syndrome (SIDS) or suffocation.
Innovation Solution
A multi-mode secure sleeping bag designed specifically for young children, featuring a detachable safety member that holds the child in a specific position to ensure they sleep on their back, along with safety pockets to eliminate loose ends and prevent suffocation. The sleeping bag is also designed to be portable, washable, and adaptable for different modes of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sleeping bags are used for young children, then warmth and comfort are provided, but safety hazards arise from loose flaps and small articles that may cause suffocation or SIDS
Solution Approach 1:
The patent removes hazardous elements (loose flaps, small articles, traditional zippers) from the sleeping bag design. Instead, it uses integrated snap fasteners and eliminates unnecessary components that could pose suffocation risks to infants and young children.
Solution Approach 2:
The sleeping bag incorporates different structural qualities in different regions: the head area has no loose flaps or bumpers, the body area uses secure snap fasteners instead of zippers, and the overall design eliminates small detachable parts while maintaining warmth and comfort functionality.
2Reliability
If conventional sleeping bags with padding or pillows are used to restrict sleeping position, then warmth is provided, but the risk of SIDS increases due to improper sleeping position restriction
Solution Approach 1:
The patent eliminates traditional padding, pillows, and bumper pads from the sleeping bag design. Instead, it uses the fitted sheet configuration and snap fastener system to gently guide and maintain proper sleeping position without adding suffocation risks associated with loose padding or pillows.
Solution Approach 2:
The sleeping bag provides different functional qualities in different areas: the head region maintains complete openness without any padding or bumpers to prevent suffocation, while the body and foot areas use secure fabric construction to maintain position without restrictive pillows.
3Temperature
If sleeping bags are designed for adults and older children, then insulation and comfort are adequate, but they are not suitable for young children or babies due to hazardous features
Solution Approach 1:
The sleeping bag maintains adequate insulation through its multi-layer construction (fitted sheet, blanket sheet, cover sheet) while simultaneously applying different safety qualities to different regions - eliminating hazardous features entirely from the design while preserving thermal functionality through the layered fabric structure.
Solution Approach 2:
The patent removes all hazardous features (loose flaps, small articles, traditional zippers, bumper pads, pillows) from the sleeping bag while retaining and optimizing the insulation functionality through integrated snap fasteners and a multi-layer fabric system that provides warmth without safety risks.
4Ease of operation
If conventional sleeping bags are used, then portability is provided, but security and safety for young children are compromised
Solution Approach 1:
The patent combines portability features with security features into a unified design - the snap fastener system provides both secure closure for child safety and easy attachment/detachment for portability, while the fitted sheet configuration maintains both security and ease of use.
Solution Approach 2:
The patent eliminates traditional zippers and complex fastening systems that compromise child security, replacing them with simple snap fasteners that provide both secure closure for safety and easy operation for portability and convenience.

AI summary
A sleeping bag comprising a bed sheet and a cover sheet secured together at a first end and at a portion of the sides to form a sleeping pocket. The bed sheet includes at least one of reversible pockets and a set of slits for securing the sleeping bag to a support. The cover sheet includes a reversible pocket at one end to secure the cover sheet in certain modes of operation. The sleeping bag further comprises a blanket sheet disposed between the bed sheet and a cover sheet to provide added comfort. The sleeping bag further comprises a holding member removably attached to at least one of the bed sheet and the cover sheet to support shoulders or lower body of a child such that the child is on the back while sleeping and the child is unable to slide entire body inside the sleeping pocket.
