Play Yard Removable Liner Design for Cleaning and Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing play yards often have non-removable fabric enclosures that are difficult to clean and secure to the frame, leading to durability issues and damage during washing.
Innovation Solution
A play yard design featuring a removable liner with sleeves that slide over movable retention members on the frame, allowing for easy attachment and detachment, and a frame that can be collapsed for storage, with secure fastening mechanisms to maintain the liner's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the fabric enclosure is made non-removable to simplify the structure, then the device complexity is reduced, but the ease of operation for cleaning becomes difficult
Solution Approach 1:
The fabric enclosure is divided into separate removable panels that can be detached from the frame. Each panel is connected via sleeves that slide over vertical frame members, allowing individual panels to be removed for cleaning while the rest of the structure remains intact.
Solution Approach 2:
The fabric enclosure panels are extracted from the fixed structure and made removable. The panels can be completely detached from the frame by sliding the sleeves off the vertical frame members, enabling easy removal for washing and maintenance.
2Reliability
If vertical posts are added to the fabric enclosure for secure attachment, then the reliability of attachment is improved, but the device complexity increases and the posts can be damaged during washing
Solution Approach 1:
Instead of using rigid vertical posts, the invention uses flexible fabric sleeves that replicate the attachment function. The sleeves slide over the vertical frame members and can be easily removed for washing, eliminating the damage issue while maintaining attachment security during use.
Solution Approach 2:
The rigid vertical posts are replaced with flexible fabric sleeves. These thin film structures slide over the frame members to provide attachment while being washable and damage-resistant. The flexibility allows easy installation and removal without the fragility of rigid posts.
3Ease of operation
If the fabric enclosure is made removable for easy cleaning, then the ease of operation for washing is improved, but the device complexity increases and attachment security may be compromised
Solution Approach 1:
The fabric sleeves are nested over the vertical frame members, creating a simple insertion-removal mechanism. The sleeves slide onto the frame members to secure the panels during use and can be easily slipped off for washing, providing a low-complexity attachment system that maintains security while enabling convenient cleaning.
4Ease of operation
If the play yard frame is made collapsible for portability, then the ease of operation for storage is improved, but the strength and stability of the structure may be reduced
Solution Approach 1:
The frame is designed with movable connections between horizontal and vertical members, allowing it to transition between an expanded stable configuration for use and a collapsed compact configuration for storage. The dynamic joints maintain structural integrity during both states while enabling portability.

AI summary
Various embodiments of the present invention are directed to a play yard configured for providing an enclosed space for a child. According to various embodiments, the play yard comprises a rigid support frame and removable, flexible liner. The frame includes one or more moveable retention members configured to engage the liner in order to form a bounded play yard space. By permitting the liner to be secured to the frame via the retention members, a user is able to easily secure the liner to the frame for use and remove the liner from the frame for washing.
