Adjustable Bassinet Assembly for Inclined Baby Head Support
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 elevate the baby's head for enhanced comfort.
Innovation Solution
A play yard assembly with a bassinet that includes a frame and a bassinet with a head end and tail end, where the head end is adjustable to two height positions, allowing the bed bottom to incline so the baby's head is raised above their feet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bassinet is designed with fixed horizontal bed bottom, then the structure is simple, but the baby's comfort is reduced due to inability to raise head
Solution Approach 1:
The bassinet bed bottom is designed to be dynamically adjustable between horizontal and inclined positions. The connection between the bassinet and frame allows the bed bottom to rotate or pivot, enabling transition from a fixed horizontal state to an inclined state that raises the baby's head, thus providing dynamic adaptability without permanent structural complexity
Solution Approach 2:
The bassinet structure is segmented into movable and fixed portions. The bed bottom is separated from the frame structure, allowing independent adjustment of the bed bottom angle while keeping the overall bassinet framework relatively simple. This segmentation enables the incline function without requiring complete structural redesign
2Ease of operation
If the head end of bassinet is adjustable to two height positions, then the baby's head can be elevated for comfort, but the device complexity increases
Solution Approach 1:
Instead of providing continuous or multi-position adjustment, the invention implements adjustment to just two specific height positions (horizontal and inclined). This partial action approach provides sufficient comfort benefit for baby positioning while avoiding the complexity of continuous adjustment mechanisms with multiple stops or fine-tuning capabilities
Solution Approach 2:
The adjustment mechanism is localized to the connection point between the bassinet bed bottom and the frame. Rather than requiring complex mechanisms throughout the entire bassinet structure, the inclination capability is concentrated at the specific joint where the bed bottom connects to the frame, simplifying the overall device while achieving the desired functionality

AI summary
A play yard assembly comprises a frame and a bassinet. The frame includes a frame head, a frame tail, and left and right side portions connected between the frame head and the frame tail to define an accommodating space thereamong. The bassinet has a head end, a tail end, a bed bottom connected between the head end and the tail end. The head end is positionable relative to the frame at a first height position and a second height position higher than the first height position. The bed bottom has a first end portion connected to the tail end, and a second end portion connected to the head end. The second end portion of the bed bottom is higher than that of the first end portion of the bed bottom when the head end is disposed at the second height position.
