Play Yard Bassinet Support With Quick Two-Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional play yards with bassinets lack a simple and efficient height adjustment mechanism, making it difficult to quickly change the bassinet's position during use.
Innovation Solution
A play yard design featuring a first frame unit with upright rods and corner couplers, and a second frame unit with connecting rods that can be easily moved between lower and higher positions, allowing for quick adjustment of the bassinet's height by pivoting and engaging/disengaging the bent end segments with positioning slots and protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional height adjustment mechanism is used for the bassinet, then the bassinet can be adjusted to different heights, but the mechanism becomes complicated and slow to operate
Solution Approach 1:
The bassinet support structure transitions from a fixed position to a dynamically adjustable position. The connecting rod with bent end segments enables the bassinet to move between a lower position (when bent segments are engaged with corner couplers) and a higher position (when disconnected), providing dynamic height adjustment without complex mechanisms
Solution Approach 2:
The height adjustment function is segmented into two distinct positions (lower and higher) rather than requiring a continuous or multi-position complex mechanism. The bent end segments of the connecting rod can be selectively engaged or disengaged from the corner couplers to achieve these discrete positions, simplifying the overall adjustment mechanism
2Adaptability or versatility
If a conventional height adjustment mechanism is used for the bassinet, then height adjustment is possible, but the operation speed is slow
Solution Approach 1:
The bassinet support structure transitions from a fixed position to a dynamically adjustable position. The connecting rod with bent end segments enables the bassinet to move between a lower position (when bent segments are engaged with corner couplers) and a higher position (when disconnected), providing dynamic height adjustment without complex mechanisms
Solution Approach 2:
The height adjustment mechanism is designed to be self-operating through simple user action. The bent end segments can be easily disconnected from or engaged with the corner couplers by manual manipulation, allowing quick height adjustment without requiring complex controls or multiple steps

AI summary
A play yard includes a first frame unit and a bassinet-supporting second frame unit. The first frame unit includes a plurality of spaced-apart upright rods, a plurality of corner couplers that are provided respectively on the upright rods, and a plurality of side rods, each interconnecting a pair of the corner couplers. The second frame unit includes a plurality of connecting rods, each having a supporting segment and a pair of bent end segments that are connected respectively to longitudinally opposite ends of the supporting segment, and that are connected movably and respectively to a pair of the corner couplers, such that each of the connecting rods is selectively positioned relative to the first frame unit at a lower position and a higher position located above the lower position.
