Collapsible Playard Bassinet Frame With Secure Two-Axis Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collapsible playard accessories often lack portability and compactness, as they do not feature collapsible frames, which complicates storage and transportation, and poses a risk of unintentional detachment and injury.
Innovation Solution
A foldable frame for playard accessories that can be selectively attached to an upper frame rail, featuring pivotally connected upper and lower frame rails with telescoping sections, allowing the frame to collapse about two axes, ensuring secure attachment and easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a collapsible playard frame is used, then portability and compactness are improved, but accessory stability and security against unintentional detachment deteriorate
Solution Approach 1:
The accessory frame employs dynamic hinge connections that allow the frame to pivot between deployed and collapsed positions. The hinge mechanism includes safety features that maintain stability when deployed while enabling easy collapse for portability, thus resolving the contradiction between operational ease and reliability.
Solution Approach 2:
The frame is divided into segmented components connected by hinges, allowing independent movement of frame sections. This segmentation enables the frame to maintain structural integrity when deployed while facilitating compact folding for transport, addressing both portability and stability requirements.
2Reliability
If accessory frames are made rigid for stability, then reliability is improved, but compactness and portability worsen
Solution Approach 1:
The frame transitions from a static rigid structure to a dynamic system with controlled movement. Hinge connections with safety mechanisms provide rigidity and stability during use, while allowing the frame to collapse into a compact configuration for storage, thus resolving the contradiction between reliability and compactness.
3Volume of moving object
If collapsible mechanism is added to accessory frame, then compactness is improved, but device complexity and risk of unintentional detachment worsen
Solution Approach 1:
The hinge mechanism incorporates safety features that prevent unintentional detachment while maintaining simplicity. The dynamic connection allows easy collapse for compact storage but includes provisions to ensure the frame remains securely attached when deployed, balancing compactness with acceptable complexity.
4Volume of moving object
If collapsible mechanism is added to accessory frame, then compactness is improved, but reliability and risk of unintentional detachment worsen
Solution Approach 1:
The hinge connection system includes safety mechanisms that prevent accidental collapse or detachment during use. The dynamic design allows intentional collapse for compact storage while maintaining secure attachment when deployed, thus improving compactness without compromising reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The foldable frame provides a compact and portable solution for playard accessories, ensuring secure attachment and preventing unintentional detachment, while maintaining stability and ease of use.
Implementation Method 1
The upper and lower frame rails are pivotally connected at each end to the end members to enable pivoting of the frame rails about transverse axes generally perpendicular to the longitudinal axis
Implementation Method 2
The lower frame rails incorporate telescoping sections enabling the length between the pivoting connections to be varied

AI summary
A foldable frame for supporting a bassinet for fitment on a child's playard comprising a pair of longitudinally extending upper frame rails connected at each end to a one of pair of transversely extending end members for pivotal movement about the transverse axis. A longitudinally extending lower frame rail is connected at each end to the respective end members and spaced apart from the upper frame rails. The length of the lower frame may be adjusted enabling the end members to pivot inwardly from an unfolded position toward a folded position and reduce the spacing between the upper and lower frame rails. The upper frame rails further include a wing pivot at each end member connection which are aligned to allow the upper frame rails to pivot about a longitudinal axis and reduce the frame width when the frame is folded, but do not allow pivoting when the frame is unfolded.
