Sling Child Carrier Cradle for Infant Head and Neck Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable child carriers lack adequate support for the head and neck of infants, force them into awkward positions, and are often difficult to use or manufacture, leading to discomfort and inefficiency.
Innovation Solution
A flexible sling child carrier with a sash and cradle configuration that supports the child in a horizontal position, providing head and neck support, and includes a flap for secure wrapping around the body, using adjustable fasteners for secure attachment and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional backpack-like front carriers are used, then hands-free carrying is achieved, but adequate head and neck support for infants is not provided
Solution Approach 1:
The carrier is divided into distinct functional regions: a head support region with contoured shaping and optional head support elements, a torso region, and leg regions. This segmentation allows each area to provide specialized support appropriate for infant anatomy while maintaining hands-free operation.
Solution Approach 2:
The carrier incorporates localized features such as contoured head support regions, padded areas, and strategically positioned structural elements that provide enhanced support where needed (head, neck, spine) while maintaining flexibility in other areas. This allows adequate head and neck support without compromising ease of use.
2Strength
If conventional carriers force child into vertically-oriented position, then carrying capacity is improved, but child is forced into awkward position with arms and legs extending laterally
Solution Approach 1:
The carrier allows dynamic positioning adjustments through movable components and flexible construction, enabling the child to be positioned in natural, comfortable orientations (vertical, horizontal, or angled) while maintaining secure support. The arms and legs can be positioned naturally against the wearer's body rather than forced into lateral extensions.
3Reliability
If conventional carriers are designed for secure carrying, then safety is improved, but they become difficult to use and manufacture
Solution Approach 1:
The carrier integrates multiple security features (adjustable fasteners, harness systems, positioning elements) into a unified, streamlined structure that provides secure carrying without requiring complex assembly or operation. The design combines head support, torso support, and leg support into a single integrated unit that is both safe and simple to use.
4Reliability
If adequate head and neck support is provided for infants, then safety is improved, but carrier complexity and manufacturing difficulty increase
Solution Approach 1:
The carrier utilizes flexible, contoured materials and thin-shell construction techniques to create effective head and neck support structures. These flexible support elements can be manufactured using standard textile and molding processes, avoiding the need for complex rigid structures while still providing adequate support for infant heads and necks.

AI summary
Wearable child carriers and methods for use are disclosed. A representative device includes a sash configured to rest across a shoulder of the user and be positioned over the user's torso, and a cradle supported by the sash and configured to support and secure a child in a generally horizontal position against a frontside of the user's body. The cradle can include a head region supported by one end of the sash and configured to support and secure the sides and back of the child's head, a body region supported by another end of the sash and configured to support the child's torso and legs, and a flap extending from the body region and configured to wrap at least partially around the child's body and a portion of the body region.
