Folding Walker with X-Shaped Leg Assemblies for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant walkers with wheels are rigid structures that cannot be easily disassembled or folded for compact storage and transport to different locations, such as daycare centers or parks.
Innovation Solution
A folding walker design with adjustable height and collapsible leg assemblies that allow the walker to be configured into a compact form, featuring four and two X-shaped leg assemblies, and a third embodiment with four vertical legs and a folding support frame that collapses horizontally for easy transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the walker uses rigid legs to support the child seat, then the structural stability is improved, but the ease of transport and storage deteriorates because the structure cannot be folded or disassembled
Solution Approach 1:
The walker frame is divided into multiple collapsible leg assemblies (X-shaped or vertical legs with folding mechanisms) that can be separated into distinct segments. These segments can be folded together into a compact configuration for transport while maintaining structural integrity when assembled and locked in place during use.
2Ease of manufacture
If the walker uses fixed rigid structure, then the manufacturing simplicity is improved, but the adaptability deteriorates because the height cannot be adjusted for different children
Solution Approach 1:
The walker incorporates adjustable height mechanisms in the leg assemblies, allowing the frame height to be dynamically changed to accommodate children of different sizes. This is achieved through telescopic legs, adjustable joint positions, or interchangeable leg components that maintain structural stability while providing customization.
3Ease of operation
If the walker uses collapsible leg assemblies, then the ease of storage is improved, but the device complexity increases due to additional folding mechanisms
Solution Approach 1:
The collapsible leg assemblies are designed so that when folded, the upper portions nest within or alongside the lower portions, creating a compact storage configuration. The X-shaped or telescopic designs allow components to occupy minimal space when collapsed while maintaining simple mechanical mechanisms for deployment and locking.

AI summary
A child's folding walker with caster wheels that is adjustable in height to permit a child to sit and touch the ground and move the walker. The walker includes four vertical legs, and upper platform that attaches to a suspended seat with leg holes configured to hold a sitting child in a suspended position above the floor. A folding support frame holds the four legs in a fixed position when used as a walker but collapses into a folding configuration for compact storage. In one embodiment, the walker includes four X-shaped leg assemblies that enable the walker to collapse into a compact vertical configuration. In another embodiment, the walker has two X-shaped leg assemblies that enable the walker to collapse into compact horizontal configuration. In a third embodiment, the walker has four vertical legs and two collapsible side frames that enabling the walker to collapse into a vertical configuration.
