Foldable Crib Frame for Switching Between Rocking and Stationary Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cribs cannot easily switch between cradle-type and stationary-type configurations, which limits their functionality in providing a comfortable sleeping environment for infants and young children.
Innovation Solution
A crib design featuring a frame assembly with foldable plates that pivot between unfolded and folded positions, allowing the crib to swing as a cradle or function as a stable bed, with adjustable height and the ability to be easily folded and carried, utilizing a bracket assembly with telescopic sections and a pull-rod mechanism for smooth conversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the crib is designed as a stationary-type only, then the structural stability is improved, but the functionality is limited and cannot function as a cradle
Solution Approach 1:
The patent applies the dynamics principle by making the bottom plates pivotable between fixed and curved positions. The bottom plates can be rotated from a fixed flat position (for stationary crib mode) to a curved rocking position (for cradle mode), enabling the crib to dynamically adapt its function based on user needs while maintaining structural integrity through the pivot connection mechanism
2Adaptability or versatility
If the crib is designed with convertible functionality, then the adaptability is improved, but the switching between states is not smooth and convenient
Solution Approach 1:
The pivotable bottom plate mechanism allows smooth transitions between cradle and stationary modes through simple rotational movement. The dynamic design enables users to switch between states by easily rotating the bottom plates without complex assembly or disassembly operations, significantly improving operational convenience
3Adaptability or versatility
If the crib is designed as a fixed structure, then the manufacturing simplicity is improved, but the space occupancy is increased and portability is reduced
Solution Approach 1:
The patent divides the crib structure into separable components, particularly the bottom plates that can be independently pivoted and positioned. This segmentation allows the crib to be folded into a compact configuration for portability while maintaining the integrity of individual components, reducing space occupancy without requiring complex disassembly mechanisms

AI summary
The present invention provides a crib. The crib comprises an enclosing element (10) configured for holding a baby therein, a frame assembly (31, 32) configured for supporting the enclosing element (10), a bracket assembly (21) connected to the frame assembly (31, 32) and configured for supporting the frame assembly (31, 32), and at least two foldable plates (40) pivotably connected to the bracket assembly (21) such that each foldable plate (40) can rotate between an unfolded position and a folded position. Each foldable plate (40) has a curved surface, the curved surfaces of the at least two foldable plates (40) contact the ground to enable the crib to swing when the at least two foldable plates (40) are in their unfolded position. The present invention also provides a crib frame.
