Collapsible Highchair Stand With Pivoting Legs to Prevent Tipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible high chair devices for infants are not portable due to their inability to be easily collapsed for storage or transportation, and they often tip over when used as a high chair with an infant seated.
Innovation Solution
A convertible high chair and infant carrier stand device featuring a collapsible basket with flexible walls and a base with pivoting legs, allowing the device to be compactly stored and transported, and incorporating a back support panel and crotch panel that can be secured in operative positions to prevent tipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the high chair device is made collapsible for portable storage and transportation, then ease of operation is improved, but stability is worsened causing the device to tip over when an infant is seated
Solution Approach 1:
The device employs dynamic legs that can pivot between a collapsed position for portability and an extended, splayed position for stability. The legs are designed to be movable rather than fixed, allowing the structure to transition between compact storage mode and stable operational mode, directly resolving the contradiction between portability and stability
Solution Approach 2:
The high chair is divided into separable components including the basket, base, back support panel, and crotch panel. The base with its pivoting legs can be collapsed independently from the basket, allowing the structure to be segmented for easy storage while maintaining stability when assembled and used, addressing the portability-stability tradeoff
2Device complexity
If the device structure is simplified for easy collapse and storage, then device complexity is reduced, but stability is worsened making the device prone to tipping
Solution Approach 1:
The device utilizes flexible mesh panels for the basket walls, back support, and crotch panel instead of rigid structural elements. These flexible components can be easily collapsed and stored without complex mechanisms, yet when assembled they provide sufficient structural integrity and stability to support an infant without tipping
Solution Approach 2:
The pivoting legs provide a dynamic stabilization mechanism that compensates for the simplified structure. When extended and splayed outward during use, the legs create a wide base of support that enhances stability despite the overall simplicity of the device design, resolving the contradiction between low complexity and high stability

AI summary
A collapsible convertible highchair and infant carrier stand device is provided. It includes basket and a base supporting the basket. The basket is configured to receive an infant carrier or to directly support a seated infant. The basket includes a bottom wall, a first end wall, a pair of sidewalls, a second end wall, a crotch panel and a back support panel. The crotch panel and the back support panel are located in the basket between the first and second end walls. Each is configured to be pivoted from a stowed position, when the device is holding an infant carrier, to an operative position when the device is directly supporting the infant. In the operative position the infant's back will rest against the back support panel and his/her legs will extend through opening in the crotch panel and a window in the first end wall.
