Foldable Bassinet Hinge Lock for Simplified Folding and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional play yards with bassinets are unnecessarily large and have complex folding and unfolding procedures, making them inconvenient for storage.
Innovation Solution
A bassinet locking mechanism with a first hinge component, a second hinge component, and a locking hub component, along with a resilient component and a bassinet releasing mechanism, allows for easy folding and unfolding by constraining and allowing relative rotation between the components using teeth engagement and a compressed spiral spring, facilitated by a pull wire mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional play yard with bassinet is used, then the bassinet can be supported and installed, but the device becomes unnecessarily large and has complicated folding and unfolding procedures
Solution Approach 1:
The bassinet support structure is divided into multiple telescopic sections (first section, second section, third section) that can independently move relative to each other. Each section has its own locking mechanism with teeth and locking hubs, allowing the structure to be segmented into collapsible units that fold independently, simplifying the overall folding operation while maintaining support functionality.
Solution Approach 2:
The telescopic sections are designed to nest within each other when folded, with the second section telescoping into the first section and the third section telescoping into the second section. The locking hubs retract into the hinge components when not in use, creating a compact nested configuration that minimizes storage volume while maintaining structural integrity when deployed.
2Volume of moving object
If a conventional play yard with bassinet is used, then the bassinet can be supported, but the device occupies excessive storage volume
Solution Approach 1:
The telescopic sections are designed to nest within each other when folded, with the second section telescoping into the first section and the third section telescoping into the second section. The locking hubs retract into the hinge components when not in use, creating a compact nested configuration that minimizes storage volume while maintaining structural integrity when deployed.
Solution Approach 2:
The locking mechanism uses localized tooth engagement at specific positions along the telescopic sections. The teeth are positioned to engage only when the sections are fully extended or at predetermined intervals, providing structural stability at these discrete points while allowing continuous movement between locked positions. This localized locking approach maintains stability without requiring the entire structure to be rigidly fixed.
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
Enables simple and convenient operation for folding and unfolding the bassinet apparatus, minimizing volume for storage by allowing easy engagement and disengagement of the locking mechanism.
Implementation Method 1
A resilient component disposed between the first hinge component and the locking hub component. A resilient recovering force of the resilient component is used to move the locking hub component toward the second hinge component. The resilient component is a compressed spiral spring.

AI summary
A foldable bassinet including a center tube, at least two frames, and at least two frame connectors. Each frame connector is disposed on a corresponding frame. The center tube is connected between the at least two frame connectors. At least one of the frame connectors includes a bassinet lock, a first tube and a second tube. The bassinet lock includes a first hinge fixed to the first tube, a second hinge fixed to the second tube and rotatably connected to the first hinge, and a locking hub disposed on the center tube and slidably located between the first hinge and the second hinge. When the bassinet lock is unlocked, the center tube is movable in an upward direction and the foldable bassinet is movable from an unfolded position to a folded position.
