Adjustable Bassinet Assembly for Raised-Head Baby Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional play yards with bassinets only allow babies to lie in a horizontal position, lacking the ability to adjust the bassinet to raise the baby's head for enhanced comfort.
Innovation Solution
The play yard assembly includes a bassinet with a height-adjustable feature, utilizing hanging rods and connecting seats or hook-and-loop fasteners to change the angle of the bed, allowing the baby's head to be raised above their feet by altering the position of the head end relative to the tail end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bassinet is designed with a fixed horizontal position, then the structure is simple and stable, but the baby's comfort is reduced due to inability to raise the head
Solution Approach 1:
The bassinet bed bottom is designed with adjustable height positions at the head end, allowing it to transition from a fixed horizontal state to an inclined state where the head is elevated. This dynamic adjustment capability enables the bassinet to adapt to different comfort requirements while maintaining structural integrity through defined positioning points.
Solution Approach 2:
The bed bottom is divided into segments with different height positions, particularly at the head end, allowing independent adjustment of the head elevation while keeping the rest of the bassinet structure stable. This segmentation enables comfort adjustment without requiring complete structural redesign.
2Adaptability or versatility
If the bassinet bed is made adjustable to raise the head, then baby comfort is enhanced, but the device complexity increases
Solution Approach 1:
The bassinet incorporates a height adjustment mechanism that enables the head end to move between multiple predetermined positions (first, second, and third height positions). This dynamic system allows the bassinet to adapt to different baby comfort needs while maintaining manageable complexity through defined positional states rather than continuous adjustment.

AI summary
A play yard assembly comprises a frame (1, 3) and a bassinet (2, 4). The frame (1, 3) includes a frame head (11, 31), a frame tail (12, 32), and left and right side portions (13, 14, 33, 34) connected between the frame head (11, 31) and the frame tail (12, 32) to define an accommodating space (10, 30) thereamong. The bassinet (2, 4) has a head end (21, 41), a tail end (22, 42) , a bed bottom (23, 43) connected between the head end (21, 41 and the tail end (22, 42). The head end (21, 41) is positionable relative to the frame (1, 3) at a first height position and a second height position higher than the first height position. The bed bottom (23, 43) has a first end portion (231, 433) connected to the tail end (22, 42), and a second end portion (232, 434) connected to the head end (21, 41). The second end portion (232, 434) of the bed bottom (23, 43) is higher than that of the first end portion (231, 433) of the bed bottom (23, 43) when the head end (21, 41) is disposed at the second height position.
