Reversible Crib Changing Table With Pivoting Locking Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cribs with integrated changing tables and sleeping apparatuses occupy excessive space and have complex structures, making them inefficient in space utilization and inconvenient for packaging and transportation due to bulky brackets.
Innovation Solution
A reversible changing table with a pivoting mechanism and locking system allows the bracket to rotate and switch between different surfaces, reducing space occupancy and simplifying the structure, while the outer and inner tubes slide to minimize packaging volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the changing table and sleeping apparatus are arranged side by side on the crib frame, then both functions are provided, but the space of the crib is occupied excessively
Solution Approach 1:
The bracket is designed to serve multiple functions: it supports the changing table surface, enables rotation via the pivoting mechanism, and provides locking capability. By integrating these functions into a single bracket structure, the patent eliminates the need for separate sleeping apparatus, allowing the same space to serve both changing and sleeping purposes at different times.
Solution Approach 2:
The bracket is made rotatable through the pivoting mechanism, allowing it to dynamically change position and orientation. This dynamic capability enables the bracket to switch between supporting the changing table surface and being folded away, thereby adapting the crib space for different uses without requiring permanent dedicated space for each function.
2Device complexity
If the bracket is made of one single metal tube with fixed volume, then the structure is simple, but the volume is larger than necessary and requires more package materials
Solution Approach 1:
The bracket is divided into multiple segments: the first bracket portion, the second bracket portion, and the connecting portion with the pivoting mechanism. This segmentation allows each part to be optimized independently - the connecting portion can be minimized for compact packaging while the support portions maintain structural integrity. The segmented design also enables the bracket to be folded into a compact configuration for storage and transport.
Solution Approach 2:
The bracket portions are designed to nest within each other when folded, with the second bracket portion fitting within or adjacent to the first bracket portion. This nesting arrangement minimizes the overall volume of the bracket when not in use, reducing packaging requirements and facilitating easier transportation while maintaining the simple metal tube construction.
3Volume of stationary object
If the bracket volume is reduced for easier packaging, then packaging and transportation become more convenient, but the bracket may lose structural strength
Solution Approach 1:
The bracket employs different local qualities in different portions: the first and second bracket portions use thicker metal tubes for structural strength and load-bearing capacity, while the connecting portion uses a more compact design optimized for rotation and space efficiency. The pivoting mechanism incorporates reinforcement features locally where stress concentrations occur, maintaining overall strength while minimizing total volume.
Solution Approach 2:
The bracket utilizes composite construction combining metal tubes with integrated plastic members or coatings. This composite approach allows the metal portions to provide structural strength while the plastic components can be designed for compactness and ease of packaging. The combination enables volume reduction without sacrificing the load-bearing capacity required for supporting the changing table surface.

AI summary
A reversible changing table installed on a crib frame of a crib includes a bracket and a pivoting mechanism. The pivoting mechanism is disposed on at least one corner of the bracket and has a locking mechanism. The bracket is installed on the crib frame through the pivoting mechanism such that the bracket is capable of being rotated with respect to the crib frame, and the locking mechanism is used for preventing the bracket from being rotated with respect to the crib frame.
