Self-Deploying Child Bed With Buttress Bars to Prevent Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional children's beds, such as folding beds and baby cots, are cumbersome, difficult to set up and take down, and lack sufficient support as children grow, leading to sagging structures and safety concerns.
Innovation Solution
A self-deployable children's play area device featuring a hoop structure with two erect hoop ends, buttress bars that absorb bearing forces, and a reversible connection system allowing one end of each bar to remain fixed while the other end is free, facilitating easy installation and storage, and providing enhanced support and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional folding beds are used, then the sleeping space is defined with flexible walls, but the bed becomes heavy to transport and cumbersome when folded
Solution Approach 1:
The bed structure is divided into modular components: a collapsible frame with segmented legs, separate mattress, and detachable bedding components. This segmentation allows each part to be lightweight yet functional, reducing overall transport weight while maintaining sleeping space integrity when assembled.
Solution Approach 2:
The bed employs dynamic, collapsible legs that can transition between extended (for stability) and retracted (for compact storage) positions. This dynamic structure eliminates the need for heavy fixed frames, reducing transport weight while ensuring reliability when the bed is in use.
2Reliability
If conventional folding beds are used, then the sleeping space is defined with flexible walls, but the bed becomes complicated to implement and fold up
Solution Approach 1:
The frame is segmented into standardized connection modules that simplify assembly. Each leg and support structure uses uniform connection mechanisms, reducing the complexity of implementation and making the folding process more intuitive and easier to operate.
Solution Approach 2:
The bed incorporates self-locking mechanisms and gravity-assisted folding features that allow the structure to automatically secure itself during assembly and collapse into a compact form during folding, reducing the manual effort and complexity required for operation.
3Reliability
If baby cots with hoop structure are used, then the sleeping space is maintained, but the structure sags when the child grows and wants to lean on it
Solution Approach 1:
The bed uses adjustable, extendable legs that can be lengthened or repositioned as the child grows, maintaining structural support strength. The dynamic leg system prevents sagging by providing stable, ground-level support points that adapt to the child's weight and movement, unlike fixed hoop structures.
Solution Approach 2:
The traditional hoop-based mechanical support system is replaced with a leg-based support system that directly contacts the ground, providing superior structural strength and resistance to sagging. This substitution maintains the sleeping space while significantly improving load-bearing capacity.
4Ease of manufacture
If removable bars are attached to loops in baby cots, then the structure can be assembled, but the bars must be attached and removed after each use
Solution Approach 1:
The support structure is segmented into permanently attached frame components and removable bedding elements. This segmentation allows the main structural bars to remain fixed during use, eliminating the need for repeated attachment and removal, while still allowing easy disassembly for storage by removing only the bedding components.
Solution Approach 2:
The bed employs dynamically adjustable components such as extendable legs and removable mattress covers, rather than requiring removal of structural bars. This dynamic design maintains ease of manufacture with simple assembly while dramatically improving ease of operation for repeated use.

AI summary
A device (1) for self-deploying children, comprising a hoop structure (110, 120) capable of supporting in the deployed state at least one wall (20) of flexible material defining a space for accommodating a child, and at least four bars buttress (201, 201') to counter support on the hoop structure. For at least one of these bars, only one (211, 211') of the two ends of the bar is secured to the hoop structure by a fixed link, so that said bar can remain linked to the hoop structure when said structure passes from the folded state to the deployed state and/or vice versa.
