Height-Adjustable Play Yard Bassinet With Taut Lower Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing play yards do not provide a taut fabric enclosure around the frame from the upper frame members to the floor, and lack an adjustable bassinet structure that can extend its use beyond infancy, as the bassinet height is fixed, limiting its usability for older infants.
Innovation Solution
A fabric body for the play yard that extends from the upper horizontal frame members over the vertical frame members to the underlying support surface, with fastening tabs that secure to the foot members, and an adjustable bassinet structure with a separate frame and secondary fabric tunnels to adjust the bassinet floor height relative to the upper frame members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a fabric body is supported on upper horizontal frame members and pulled downward over vertical frame members to be supported on lower frame members, then the fabric body provides an open view of the underside of the play yard, but the fabric body does not provide a taut enclosure that hides the opening between the play yard floor and the floor on which the play yard is positioned
Solution Approach 1:
The fabric body is segmented into multiple panels, with the front panel extending below the lower horizontal frame members to cover the opening between the play yard floor and the floor surface, while other panels provide viewability. This segmentation allows different regions of the fabric body to serve different functions.
Solution Approach 2:
The fabric body is extended in the vertical dimension by having the front panel extend below the lower horizontal frame members, creating coverage in a previously uncovered spatial zone and hiding the opening while maintaining viewability through mesh portions in other areas.
2Ease of operation
If a bassinet assembly is supported by the play yard frame at a fixed height, then easy access to the child is provided, but the bassinet cannot be adjusted for older infants, limiting its usability
Solution Approach 1:
The bassinet assembly is made dynamically adjustable in height through multiple attachment mechanisms. The bassinet can be positioned at different heights by attaching to different frame members, and the side walls can be adjusted in height, allowing the structure to adapt to the growing needs of the child while maintaining easy access.
Solution Approach 2:
The bassinet assembly is designed with multi-functionality to serve different age groups. Through height adjustment mechanisms including attachment to different horizontal frame members and adjustable side walls, the bassinet can accommodate both young infants requiring high positioning and older infants needing lower positions, extending its usable lifespan.
3Reliability
If the fabric body is fastened using screws and plastic caps, then the fabric body is secured to the frame, but the fabric body does not extend to cover the area between the lower horizontal frame members and the support surface
Solution Approach 1:
The fabric body is segmented into multiple panels that can be independently attached to different parts of the frame. The front panel is specifically designed to extend below the lower horizontal frame members and is secured using screws and plastic caps, while other panels are attached higher up, allowing the fabric to cover the previously exposed area while maintaining secure attachment.

AI summary
A play yard frame structure includes upper and lower horizontal frame members and vertical frame members with a fabric body that extends over the exterior of the frame structure. The fabric body has fastening tabs that extend from the corners of the fabric body corresponding to the vertical frame members to be passed through openings in the foot members for fastening to the foot members on a surface that is not on the exterior of the frame structure to provide a taut panel that extends around the lower perimeter of the play yard below the lower horizontal frame members. The bassinet structure includes a height adjustment feature that enables the floor surface of the bassinet structure to be positioned selectively at multiple height positions relative to the upper horizontal frame members. In one embodiment, the fabric walls of the bassinet include secondary frame tunnels for supporting the bassinet frame.
