Convertible High Chair With Nested Booster Seat and Spring Latch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high chair and booster seat solutions lack flexibility in configuration, requiring separate products for different stages of a child's development and posing challenges in space efficiency and ease of use during travel.
Innovation Solution
A convertible high chair with a Z-shaped frame incorporating a youth chair and a booster seat that can be easily converted between configurations using a spring-loaded latch mechanism, allowing the booster seat to be nested within the youth chair and mounted on a standard chair, with a tray that can be used in both configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate high chair and booster seat products are used for different developmental stages, then each product can be optimized for its specific function, but the overall device complexity and space requirements increase
Solution Approach 1:
The high chair is designed with a universal base unit that can accommodate multiple seating configurations through interchangeable seat inserts. The base includes standardized attachment mechanisms that accept infant seats, toddler seats, and booster seats, allowing a single product to serve multiple developmental stages. This multi-functionality resolves the contradiction by providing adaptability across ages while maintaining a consistent, manageable device structure.
Solution Approach 2:
The high chair system is divided into modular components: a permanent base unit and removable seat inserts. Each seat insert is designed as a separate module that can be independently attached or detached. This segmentation allows the system to adapt to different child ages by simply swapping modules rather than redesigning the entire structure, thereby maintaining low device complexity while achieving high versatility.
2Adaptability or versatility
If multiple separate seating products are maintained for different stages, then each product can be optimized independently, but space efficiency and ease of storage deteriorate
Solution Approach 1:
The seat inserts are designed to nest within each other or within the base unit when not in use. Smaller seat components can be stored inside larger ones, and all components fit within the footprint of the base high chair frame. This nesting arrangement allows the system to adapt to different environments and child ages while requiring minimal storage space, effectively resolving the contradiction between versatility and storage volume.
3Ease of operation
If traditional high chairs with fixed structures are used, then structural stability is maintained, but ease of conversion between configurations deteriorates
Solution Approach 1:
The high chair incorporates dynamic attachment mechanisms that allow seats to be easily connected and disconnected while maintaining structural integrity. Quick-release latches and snap-fit connectors enable rapid configuration changes without compromising stability. The base frame includes reinforced mounting points that ensure secure attachment during conversion, resolving the contradiction between ease of operation and structural stability.
4Adaptability or versatility
If height adjustment mechanisms are added to accommodate different table heights, then adaptability to various environments improves, but device complexity and maintenance requirements increase
Solution Approach 1:
The height adjustment system is segmented into discrete, pre-configured levels with mechanical stops. Each height level corresponds to a specific table height requirement, and the mechanism uses simple pin-and-hole or notched rail systems rather than continuous adjustment. This segmentation provides adaptability to various table heights while maintaining simplicity that facilitates easy maintenance and repair.

AI summary
A high chair is convertible into multiple operative configurations to provide flexibility in utilization. The high chair includes a youth chair having a seat member affixed to a Z-shaped frame. A booster seat including a reclining seat back is mountable on the seat member such that the seat member is nested within the booster seat. A latch mechanism carried by the booster seat secures the booster seat to the seat member. A separate base member can also be nested into the bottom of the booster seat so that the booster seat can be utilized on a standard chair. The tray is mountable into the booster seat so that the tray can be utilized therewith irrespective of whether the booster seat is used in a high chair configuration or a booster seat configuration. The Z-frame incorporates telescopic support legs to define height adjustment for the high chair.
