Retractable Mesh Crib Sides for Gap-Free Baby Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cribs with wood slats pose safety risks due to injuries from hard surfaces and strangulation hazards from drop-down sides, while soft, breathable cribs often cannot accommodate full-size mattresses and prevent gaps.
Innovation Solution
A crib design featuring flexible, retractable sides made of breathable materials, with a locking mechanism and actuating mechanism allowing the sides to move along tracks, ensuring the sides remain within tracks during retraction and extension, and additional panels to prevent mattress gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If wood slats are used for crib sides, then structural strength is improved, but safety is worsened due to injuries from hard surfaces and strangulation hazards
Solution Approach 1:
The patent replaces rigid wood slats with flexible mesh material that forms the crib sides. This mesh material provides the necessary structural integrity while being soft and flexible, eliminating the safety hazards associated with hard wood surfaces and drop-down sides. The flexible nature of the mesh prevents injury from impact while maintaining crib strength.
Solution Approach 2:
The patent uses a composite construction combining rigid corner posts with flexible mesh material. The corner posts provide structural support and anchoring points, while the mesh material forms the breathable, flexible sides. This composite approach achieves both structural strength and safety requirements.
2Ease of operation
If drop-down sides are added to facilitate baby care, then ease of operation is improved, but safety is worsened due to separation gaps causing strangulation
Solution Approach 1:
The flexible mesh material is used to create sides that can be easily moved or removed without the rigid structure of traditional drop-down sides. The mesh's flexibility allows it to conform and maintain contact with the mattress, preventing gap formation while still enabling easy access for baby care.
3Object-affected harmful factors
If soft, breathable material is used for crib sides, then safety is improved by eliminating hard surface injuries, but adaptability is worsened by inability to accommodate full-size mattresses without gaps
Solution Approach 1:
The flexible mesh material can be adjusted and positioned to fit different mattress sizes while maintaining continuous contact. Its flexibility allows it to conform to the mattress surface, preventing gaps even with full-size mattresses, while retaining the safety benefits of soft, breathable material.
Solution Approach 2:
The mesh sides are designed to be dynamic and adjustable rather than fixed, allowing them to adapt to different mattress configurations. This dynamic design enables the mesh to maintain proper positioning and eliminate gaps while preserving the safety advantages of flexible material.
4Ease of operation
If retractable sides with tracks are implemented, then ease of operation is improved for baby access, but device complexity is worsened by locking and actuating mechanisms
Solution Approach 1:
The flexible mesh material simplifies the retractable side design by eliminating the need for complex rigid mechanisms. The mesh can be easily moved, extended, or removed without requiring sophisticated locking or actuating systems, reducing overall device complexity while maintaining ease of operation for baby access.

AI summary
A crib is provided having a plurality of sides, at least one side being made of a flexible material. One or more sides may be retractable. The retractable side may have a first edge and a second edge each being captured in a track. The crib also includes at least one locking mechanism and an actuating mechanism for releasing the locking mechanism. When the actuating mechanism is actuated, the retractable side moves along the track from a locked first position where the retractable side is fully extended into a second position where the retractable side curves under the base or rolls up into a spool.
