Swaddle Sack Foldover Cuff Design for Infant Suffocation Risk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swaddling devices restrict infants' access to their hands, preventing skin-to-skin contact and potentially exposing them to fabric chemicals, while also posing suffocation risks due to arm restraints that restrict movement.
Innovation Solution
The Swaddle Sack design features foldover mitten cuffs that allow skin-to-skin access to hands and provide flexible arm movement, reducing the risk of suffocation by enabling the baby to reposition their head if they roll over, while using soft and safe materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior swaddling devices use large wrap features with hook-and-loop fasteners to restrain baby's arms, then arm restraint function is improved, but safety deteriorates due to suffocation risk when baby rolls over
Solution Approach 1:
The patent removes the harmful hook-and-loop fastener arm restraint feature from the swaddling device while retaining the beneficial swaddling function through the sleeping sack design. This extracts the dangerous element (arm restraint that prevents movement) while preserving the useful function (swaddling support), thereby resolving the contradiction between arm restraint reliability and safety.
2Reliability
If prior swaddling devices prevent baby from accessing hands through fabric or restraints, then swaddling control is improved, but baby's natural self-soothing ability deteriorates
Solution Approach 1:
The patent removes the barrier of fabric and restraints that prevent hand access, allowing baby's hands to be freely accessible for self-soothing while maintaining swaddling control through the overall sack design. This extracts the obstructing elements while preserving the swaddling function, resolving the contradiction between swaddling control and ease of hand access.

AI summary
A swaddling device is described. The swaddling device is Y-shaped pod shaped and configured to substantially enclose a baby. The device includes sleeves having at their ends foldover mitten cuffs or similar selectively openable fasteners. The cuffs allow a caregiver to expose the hand or hands of the baby so as to provide skin-to-skin contact. Alternatively, the caregiver can close the cuffs if scratching is a concern. The device is shaped to provide support and snugness for the baby in its mid-section, while also providing sufficient space for hips and knees to flex. The design of the Swaddle Sack with swaddle snugness provides support and partial suppression of the Moro Reflex without arm restraints and allowing sufficient range of motion for baby's upper section which will reduce risk of suffocation for baby in the event that baby rolls over to prone position, because baby will be able to use his or her arms to reposition his or her head to get access to air.
