Foldable Baby Walker Rocking Frame for Stable Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby walkers with rocking chair functionality are difficult to assemble and disassemble, leading to a weak positioning effect that can be hazardous for babies, as the structures lose precision fit after frequent use, potentially causing shocks and injuries.
Innovation Solution
A baby walker design featuring a lower frame with multiple roller assemblies and parallel foldable rocking devices, allowing for easy conversion between baby walker and rocking chair modes, with a folding mechanism that maintains precision fit and safety through secure engagement of rocking plates and rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the baby walker is designed with rocking chair functionality, then the multi-functionality is improved, but the device complexity increases requiring disassembly and assembly of different lower frames
Solution Approach 1:
The patent combines the baby walker and rocking chair functions into a single integrated device. The lower frame includes both roller assemblies for walker mode and rocking devices for rocking chair mode, eliminating the need for separate frames or complex disassembly/reassembly operations.
Solution Approach 2:
The lower frame is designed with universal components that serve multiple functions. The roller assemblies and rocking devices are both mounted on the same lower frame, allowing the device to function as either a baby walker or rocking chair without requiring frame changes.
2Adaptability or versatility
If the baby walker is frequently disassembled and assembled, then the adaptability is improved, but the manufacturing precision deteriorates as structures lose precision fit
Solution Approach 1:
The patent employs a dynamic folding mechanism that allows the upper frame to be folded relative to the lower frame. This folding mechanism maintains precise positioning through engaged structures between the roller assemblies and rocking devices, enabling function conversion without compromising manufacturing precision.
3Ease of operation
If the positioning effect is weak due to frequent assembly, then the ease of operation is improved, but the reliability deteriorates causing shocks and potential injury
Solution Approach 1:
The patent incorporates shock-absorbing elements and cushioning structures in the folding mechanism and frame connections. These elements are designed beforehand to prevent shocks and injuries that could result from weak positioning, ensuring safety even during frequent function transitions.
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 design provides a safe and multi-functional baby walker that can be easily converted between modes, enhancing muscle coordination training while preventing injuries by maintaining a stable and precise positioning effect, thus promoting the safety and usability of the device.
Implementation Method 1
Each roller assembly includes a seat securely mounted on the bottom of the lower frame, an arm pivotally mounted on the seat and a roller rotatably mounted to a free end of the arm... The first seat holds the rocking plate in place when the rocking plate is vertical and horizontal relative to the supporting face of the baby walker

AI summary
A baby walker includes a lower frame and an upper frame mounted onto the lower frame via a folding device, wherein the upper frame is provided to load the body weight of the user. The lower frame has multiple roller assemblies universally mounted on a bottom thereof and two parallel foldable rocking devices mounted on the bottom of the lower frame. Each rocking device includes a first seat and a second seat respectively securely mounted on the bottom of the lower frame. A rocking plate has two opposite ends respectively pivotally mounted into a corresponding one of the first seat and the second seat. The rocking plate has a straight side and a corresponding curved side. The first seat holds the rocking plate in place when the rocking is vertical and horizontal relative to the supporting face of the baby walker.
