Detachable Play Yard Child Support Unit With Secure Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing play yard devices lack effective and versatile child support units that can be securely and easily attached to the frame, providing a safe and comfortable environment for infants and small children.
Innovation Solution
A child support unit with a subframe and couplings for attachment to the play yard frame, including a bassinet or cradle with soft-goods and a canopy, and a changing table attachment with support struts and engagement clips, allowing for secure and detachable mounting to the play yard frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a child support unit is attached to the play yard frame, then the functionality and safety for infants is improved, but the device complexity increases
Solution Approach 1:
The child support unit is designed as a separate, detachable module that can be independently attached to or removed from the play yard frame. This segmentation allows the play yard to function as a standalone device while also supporting additional child care functions when the support unit is attached, thereby increasing versatility without permanently complicating the base structure.
Solution Approach 2:
The coupling mechanism is designed to accommodate multiple types of child support units (e.g., bassinets, changing tables, activity centers) using a standardized attachment interface. This universal coupling system allows a single play yard to perform multiple child care functions through different attachable units, enhancing adaptability without increasing the complexity of the frame itself.
2Reliability
If a secure attachment mechanism is implemented, then the reliability and safety are improved, but the ease of operation deteriorates
Solution Approach 1:
The attachment mechanism is divided into distinct coupling elements: a coupling member on the child support unit and a corresponding coupling receptacle on the play yard frame. This segmentation allows for simple, tool-free attachment and detachment while maintaining secure connection through the interlocking design of these separate components.
Solution Approach 2:
The coupling mechanism is designed to be self-latching or self-securing through simple user actions such as pushing or snapping the coupling member into the receptacle. The mechanism automatically maintains secure attachment without requiring additional fastening steps, and can be easily released by simple user input, thereby achieving both safety and ease of operation.
