Folding Playpen Frame With Divider for Compact Multi-Child Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current folding playpens are difficult to collapse into a compact unit for transport and are not designed to safely accommodate multiple children of varying ages, requiring multiple playpens for families with multiple small children.
Innovation Solution
A folding playpen with a scissors mechanism that allows for easy conversion between a collapsed and extended configuration, featuring a flexible mesh and a removable bottom pad, along with a central divider that can be extended or removed to create separate areas, using fasteners like hook and loop, snap, or zipper for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional rigid playpen structure is used, then safety and stability are improved, but portability and ease of transport deteriorate
Solution Approach 1:
The playpen employs a dynamic folding frame structure with scissor-like mechanisms that allow the rigid safety enclosure to be collapsed into a compact portable form. The frame transitions between extended (safe enclosure) and collapsed (portable storage) states while maintaining structural integrity through articulated joints and locking mechanisms.
Solution Approach 2:
The playpen frame is divided into multiple segmentable sections connected by hinges and locking mechanisms. These segmented sections can be independently folded and collapsed, allowing the rigid structure to be broken down into compact units for transport while reassembling into a stable enclosure when deployed.
2Device complexity
If a single playpen is used, then simplicity and cost are improved, but safety for multiple children deteriorates
Solution Approach 1:
The playpen includes a movable partition wall that can dynamically divide the single enclosure into two separate safe zones. This partition can be positioned at different locations or removed entirely, allowing the playpen to adapt between configurations for one child or multiple children while maintaining safety standards in each zone.
Solution Approach 2:
The playpen is designed as a multi-functional unit that can safely accommodate different scenarios: single child play, multiple children play with partition, sleeping area with bassinet attachment, or storage configuration. This universal design eliminates the need for multiple separate playpens while maintaining safety for various use cases.
3Adaptability or versatility
If bassinet and multiple accessories are included, then versatility for different age groups is improved, but device complexity and cost increase
Solution Approach 1:
The bassinet and accessories are designed as detachable modular components that can be attached or removed from the main playpen structure. This segmentation allows parents to configure the playpen according to the child's age and needs without being forced to carry unnecessary accessories, reducing complexity while maintaining versatility.
Solution Approach 2:
The playpen system dynamically adapts to different developmental stages through attachable and detachable components. The bassinet can be attached when the child is an infant, removed when transitioning to toddler stage, and accessories like trays or toys can be added or removed based on current needs, allowing the structure to evolve with the child.
4Volume of moving object
If the playpen is designed for compact storage, then portability is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The folding mechanism employs spring-loaded or gravity-assisted articulations that automatically guide the frame segments into their collapsed position, reducing the physical effort required for folding. Locking mechanisms use simple cam- or lever-based systems that engage automatically during the folding motion, making the process intuitive and easy to perform.
Solution Approach 2:
The playpen's folding structure incorporates self-latching mechanisms and automatic alignment features that guide the assembly process without requiring precise manual positioning. The design allows the structure to self-correct during assembly, reducing the skill level and time needed for proper setup while achieving compact storage configuration.

AI summary
A folding playpen has a frame assembly including a plurality of parallel uprights arranged in a geometric configuration and a plurality of upper rails pivotally affixed to and extending between a top portion of adjacent ones of the uprights. A co-planar grid of braces extends between said the uprights and includes a central support block at a center of geometrically configured uprights. The braces being pivotally attached to the central support block and to a respective one of the uprights. A flexible covering extends about a periphery of the frame assembly and a pad is supported by the co-planar grid. The frame assembly is selectively collapsible from a usable configuration to a storage configuration by vertically translating the central support block from a lower position to a position proximate to a top of the uprights.
