Convertible High Chair Backrest for Portable Booster Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high chairs for children that convert into booster seats face issues with the large size of the backrest making them difficult to transport and use in non-domestic environments, and become inconvenient for children who have outgrown the need for a high chair.
Innovation Solution
A high chair design where the backrest extension can be easily removed and separated from the main backrest using interlocking members such as a groove and tongue mechanism, and hook-like elements, allowing the upper part to be used as a booster seat without the extension for grown children, while maintaining functionality for smaller children.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the backrest extension is permanently attached to the backrest to maintain safety and support for small children, then the safety and comfort for small children is improved, but the size and portability of the booster seat deteriorates
Solution Approach 1:
The backrest extension is divided into a separable component that can be detached from the main backrest. This segmentation allows the booster seat to be compact for transport while maintaining the option to attach the extension when needed for small children's safety and comfort.
Solution Approach 2:
The backrest extension transitions from a static permanent attachment to a dynamic removable component. This allows the configuration to adapt between two states: extended for safety/support and retracted for portability, resolving the contradiction between reliability and size.
2Reliability
If the backrest extension is permanently attached to ensure safety compliance, then the reliability is improved, but the portability deteriorates
Solution Approach 1:
The backrest extension transitions from a static permanent attachment to a dynamic removable component. This allows the configuration to adapt between two states: extended for safety compliance and retracted for portability, resolving the contradiction between reliability and portability.

AI summary
The present invention relates to a high chair for children convertible into a booster seat comprising an upper part (1) and a base (2), the upper part having a seating surface (6) adapted for engagement with a corresponding bearing surface (5) of the base, lateral armrest sides (7, 8), a backrest (9) whose perimeter boundary extends from one lateral side to the other, as well as a backrest extension (13) extending in cantilever fashion from the perimeter boundary of the backrest (9). The backrest extension (13) consists of a body separate from the backrest (9) and comprises members for removable connection to the perimeter boundary of the backrest (9). When the backrest extension (13) is removed, the upper part (1) of the high chair is used as a booster seat.
