Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crib frames have complex structures with many joints, leading to jamming and abrasion issues, making them inconvenient to fold and transport, and requiring a large volume when folded.
Innovation Solution
A bed frame structure with foldable support assemblies and armrests, featuring pivotally connected rods, snapping members, and elastic reset members, allowing for easy folding and reduced volume when stored, along with telescopic support legs that can switch between retracted and extended states for compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the crib frame uses a complex structure with many joints to achieve stability and support function, then the support and stability are improved, but the structure becomes prone to jamming and abrasion, reducing reliability
Solution Approach 1:
The support assembly is divided into multiple rod portions (first rod portion, second rod portion) that can be pivotally connected and folded relative to each other. This segmentation allows the structure to maintain stability when assembled while enabling easy folding and reducing wear on individual connection points.
Solution Approach 2:
The support assembly incorporates movable components including armrests that can slide up and down on the support rods, and snapping members that can engage and disengage from grooves. This dynamic design allows the structure to transition between stable supported states and folded transport states, reducing stress on joints during operation.
2Adaptability or versatility
If the crib frame uses a complex structure with many joints to achieve folding capability, then the foldability is improved, but the number of steps required to fold increases and the folded volume remains large, worsening ease of operation
Solution Approach 1:
The armrests are pre-positioned on the support rods and can be slid down to a predetermined position below the pivotally connected points before folding. This preliminary action of positioning the armrests facilitates the subsequent folding operation, reducing the number of steps required and making the folding process more intuitive and easier to perform.
Solution Approach 2:
The support rods are designed to fold nested against each other, with the first rod portion rotating into a folded state relative to the second rod portion. This nesting arrangement minimizes the folded volume of the crib frame, making it more compact and easier to transport while maintaining simple folding mechanics.
3Stability of the object's composition
If the crib frame uses a complex structure with many joints to achieve support function, then the support capability is improved, but the folded volume becomes large, worsening storage efficiency
Solution Approach 1:
The support assembly is segmented into collapsible rod portions that can be folded nested against each other. This segmentation enables the structure to maintain adequate support function when assembled while achieving a compact folded volume suitable for storage and transport.
Solution Approach 2:
The support rods are configured to fold in a nested arrangement where sections are stored within or alongside each other, minimizing the overall folded volume. This nesting design maintains structural integrity and support capability when assembled while dramatically reducing the space required for storage.

AI summary
A bed frame structure includes a bottom assembly, two support assemblies, and two armrests. Each support assembly is provided with a pivotally connected point allowing two ends of the support assembly to rotate into folding. One end of each of the two support assemblies is fixed to the bottom assembly, and the two armrests are spaced apart between the two support assemblies. Two ends of the armrests are respectively disposed on the two support assemblies in a manner of being movable up and down. The bottom assembly, the two support assemblies, and the two armrests form a rest space. The two armrests are slid down to positions below the pivotally connected points to fold the two support assemblies respectively.
