Crib Mattress Perimeter Padding for Airflow and Entrapment Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional crib and cradle bumpers pose safety hazards such as suffocation, strangulation, and injury due to inadequate airflow, loose fastening, and entrapment, while mesh bumpers lack protection from hard surfaces and may cause injury from collisions.
Innovation Solution
A bedding system with a padding assembly and cover designed to fit around the mattress perimeter, featuring angled and triangular sections made of food-grade polyethylene foam for airflow and safety, secured with hook and loop fasteners to prevent entrapment and strangulation, and a fitted sheet to keep the system in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bumpers are secured with ties to rails, then bumper stability is improved, but strangulation and choking hazards are created
Solution Approach 1:
The invention removes the tie-based fastening system from the bumper design, eliminating the strangulation hazard associated with loose cords. The bumper is instead integrated with the mattress through a different mechanism that does not involve loose ties.
Solution Approach 2:
The invention introduces a fitted sheet as an intermediary element that secures the bumper to the mattress without requiring loose ties. The fitted sheet acts as a mediator that provides stable attachment while eliminating the choking hazard of exposed cords.
2Object-affected harmful factors
If bumpers block access to vertical slats, then limb entrapment is prevented, but the child's movement is restricted
Solution Approach 1:
The invention transitions from perimeter-based protection (traditional bumpers around the crib edge) to surface-based protection (integrated into the mattress). This dimensional change allows children to move freely across the mattress surface while still being protected from slat entrapment.

AI summary
A bedding assembly for use with a mattress, the assembly including a circumscribing padding sized and shaped to extend from or rest on top of a top perimeter surface of the mattress, the padding having one or more contiguous sections, each section having a vertical outer surface positioned adjacent to sidewalk of the mattress, a horizontal bottom surface adjacent the to surface of the mattress, and an angled surface extending from the outer surface to the bottom surface, and a cover sized and shaped to secure the padding sections together in a shape that circumscribes a central portion of the mattress, and a fitted sheet sized and shaped to hold the padding and cover on the mattress.
