Foldable Crib Accessory Frame for Changing and Napping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant care accessories, such as portable cribs and play yards, lack versatility and convenience as they do not easily adapt to the changing needs of a growing child, particularly in providing a safe and functional surface for both diaper changing and napping.
Innovation Solution
A reconfigurable accessory frame that can be folded about an asymmetrically positioned transverse axis to convert between a changing table and a napper, with soft goods supported from the frame to create a level surface and storage compartment, allowing easy transition between the two functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable crib frame is used as a single-function sleeping enclosure, then it provides a safe sleeping environment, but it lacks versatility and cannot adapt to changing needs of a growing child
Solution Approach 1:
The accessory frame is designed to perform multiple functions: it can be configured as a changing table with a level surface and storage compartment, or folded into a napper structure for infant sleeping. This multi-functionality allows a single accessory to replace multiple separate items, directly addressing the versatility requirement while maintaining reasonable structural simplicity through the folding mechanism.
Solution Approach 2:
The accessory frame incorporates a folding mechanism with hinges that allow dynamic reconfiguration between two stable states: the extended changing table configuration and the folded napper configuration. This dynamic capability enables the structure to adapt its form and function based on user needs without requiring complex disassembly or multiple components.
2Adaptability or versatility
If existing infant care accessories are designed for portability, then they are easy to transport and store, but they lack the functionality to provide both diaper changing and napping surfaces
Solution Approach 1:
The folding mechanism enables easy transition between changing table and napper configurations through simple hinge movements. The asymmetric hinge positioning and foldable design allow the structure to be reconfigured without complex assembly steps, maintaining ease of operation while significantly enhancing functionality.
Solution Approach 2:
The napper configuration is created by folding the changing table structure onto itself, with the end portion moved adjacently above the remainder of the surface. This nesting approach allows the napper function to be integrated within the existing changing table structure, maximizing functionality without adding separate components that would complicate operation.
3Adaptability or versatility
If a changing table surface is provided with storage compartment, then it offers convenient diaper changing functionality, but it cannot be easily converted into a napper structure
Solution Approach 1:
The foldable frame with asymmetric hinge positioning allows the changing table structure to be dynamically reconfigured into a napper. The same structural elements that provide the changing table surface and storage compartment are reused in the folded napper configuration, achieving convertibility without requiring additional structural complexity or components.
Solution Approach 2:
The accessory frame is designed so that its structural components serve dual purposes: the extended configuration provides changing table functionality with storage, while the folded configuration creates a napper structure. This universal design ensures that the same structure can fulfill multiple functions, enhancing convertibility while avoiding the need for separate dedicated structures for each function.

AI summary
A reconfigurable accessory frame for use with an infant crib having a perimeter similarly sized to that of the top of the crib frame upon which it is used. The frame is foldable about an asymmetrically positioned transverse axis into one of the two positions. In the first position, the frame extends to substantially cover the open perimeter of the crib disposed underneath. Soft goods supported from the frame define a generally level surface that is convenient for changing an infant diaper along with a storage compartment disposed at one end. The level changing surface encompasses a majority of the area encompassed by the frame. In the second position, the frame is folded so that the end portion opposite of the storage compartment is moved into a positon adjacently above the remainder of the changing table surface. The design of the folding hinge elevates a portion of the frame and allows soft goods to hang downwardly toward and approaching the level of the soft goods defining the changing table surface to define a napper structure in the soft goods.
