Adjustable Baby Crib Bottom Frame Hub for Variable Aspect Ratios
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby crib bottom frame assemblies lack the ability to adjust angles between frame rods, requiring different couplers for varying length-to-width ratios, limiting manufacturing flexibility.
Innovation Solution
A bottom frame assembly featuring a hub unit with a stationary and rotary seat, along with a positioning mechanism, allowing adjustable angular orientation of bottom frame rods to accommodate different length-to-width ratios, comprising pivot arms and fastener slots for locking and adjusting the orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an integrally formed coupler is used to connect bottom frame rods, then the structural stability is improved, but the adaptability to different length-to-width ratios deteriorates
Solution Approach 1:
The coupler is divided into a stationary seat and a rotary seat that can rotate relative to each other. The stationary seat connects to first bottom frame rods while the rotary seat connects to second bottom frame rods, allowing independent angular adjustment of each seat to achieve different length-to-width ratios while maintaining structural stability through the segmented but connected design
Solution Approach 2:
The rotary seat is designed to rotate relative to the stationary seat, transforming the static coupler into a dynamic structure. This rotation capability allows the coupler to adapt to different angular orientations and length-to-width ratios, while the connection mechanisms maintain structural stability during and after adjustment
2Adaptability or versatility
If different specifications of couplers are prepared for different length-to-width ratios, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
A single coupler design with a rotary seat can perform multiple functions by rotating to different angular positions, replacing the need for multiple specialized couplers. The stationary seat and rotary seat connection allows one coupler to accommodate various length-to-width ratios, reducing inventory complexity while maintaining adaptability
Solution Approach 2:
The dynamic rotation capability of the rotary seat allows a single coupler to assume multiple configurations, eliminating the need for multiple static coupler specifications. This reduces device complexity by consolidating multiple fixed designs into one adjustable design

AI summary
A bottom frame assembly for a baby crib includes pairs of first and second bottom frame rods, and a hub unit that includes stationary and rotary seats. The stationary seat is connected to the first bottom frame rods at diametrically opposite positions of the stationary seat. The rotary seat is mounted rotatably on the stationary seat, and is connected to the second bottom frame rods at diametrically opposite positions of the rotary seat. By adjusting the angular orientation of the rotary seat relative to the stationary seat, the angles formed between adjacent ones of the first and second bottom frame rods can be varied so that the bottom frame assembly can suit the specified length-to-width ratio of the baby crib.
