Solution Overview
Problem
Existing collapsible infant swing frames lack structural rigidity and stability when unfolded for use and are difficult to transport due to their design.
Innovation Solution
A collapsible swing frame with a cross-brace pivotally coupled between first and second supports, providing stability and a locking mechanism for the expanded configuration, along with wheeled base hubs for improved portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a collapsible support frame is used for compact storage and transport, then portability is improved, but structural rigidity and stability deteriorate
Solution Approach 1:
The support frame is divided into multiple collapsible sections with pivot joints, allowing the frame to be segmented into foldable units. This enables the frame to collapse into a compact configuration for transport while maintaining structural integrity when expanded for use.
Solution Approach 2:
The frame incorporates dynamic elements including pivot joints and locking mechanisms that allow the structure to transition between static collapsed and expanded states. The cross-brace with locking mechanism provides dynamic stability, locking into position to maintain rigidity during use while allowing collapse for storage.
2Volume of moving object
If a collapsible support frame is used for compact storage, then storage space is reduced, but structural stability deteriorates
Solution Approach 1:
The collapsible frame sections are designed to nest within each other when collapsed, with the cross-brace and support members folding into a compact nested configuration. This minimizes storage volume while the locking mechanism ensures structural stability is restored when the frame is expanded for use.
Solution Approach 2:
The locking mechanism provides dynamic stability by transitioning from an unlocked collapsed state to a locked expanded state. When locked, the cross-brace maintains rigid connection between support members, ensuring structural stability and reliability during use.
3Stability of the object's composition
If a rigid connection is provided between support members, then structural stability is improved, but ease of folding deteriorates
Solution Approach 1:
The connection between support members transitions from rigid when locked to flexible when unlocked. The locking mechanism enables the cross-brace to provide rigid stable connection during use, while allowing easy folding when unlocked by collapsing the cross-brace and releasing the lock.
Solution Approach 2:
The locking mechanism acts as an intermediary between the rigid cross-brace connection and the folding motion. It mediates between the need for rigid stable connection during use and the need for flexible folding for storage, allowing the structure to transition between these states.

AI summary
A frame is configured to rest on a support surface and an infant-receiving receptacle (104) is supported above the support surface by the frame. The infant-receiving receptacle (104) includes a bottom/floor panel (112) forming a bed (180) for the child to sleep upon and a peripheral sidewall surrounding the bottom panel and extending between the bottom panel and the frame. The bassinet (100,200,300,500) includes a depth-adjustment mechanism that enables a caregiver to selectively adjust the depth of the infant-receiving receptacle (104) by raising or lowering the bottom panel of the infant-receiving receptacle (104). Various embodiments can also include wheels, rollers, or other mechanisms for rolling, sliding, or gliding the bassinet (100,200,300,500) across the support surface. Some embodiments include a height-adjustment mechanism, downward-recessed front wall, longitudinal-axis folding canopy (352), inverted-eggcrate bed pad (460), and/or base-positioned foot rest (250).
