Solution Overview

Problem

Existing children's booster seats are complex, costly, heavy, and difficult to use due to large repositioning mechanisms, making them hard to fit on chairs with armrests and less reliable.

Innovation Solution

An adjustable booster seat with a frame that includes vertically adjustable arms and tilt control devices, allowing for easy height and tilt adjustments with a simple, lightweight, and cost-effective mechanism, enabling the seat to be securely positioned on various chairs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If large, complex seat repositioning mechanisms are used to provide variable seating positions, then the seating position can be adjusted for children of different ages, but the booster seat becomes excessively wide, costly to manufacture, difficult to use, heavier to carry, and less reliable

Engineering Contradiction:
Improvevariable seating positionVSAvoidseat repositioning mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The booster seat is divided into separate functional components: a base unit and a child support assembly that can be independently positioned. The height adjustment and recline adjustment are separated into independent mechanisms, allowing each to be optimized separately rather than requiring a single complex repositioning system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The child support assembly is designed to nest within or upon the base unit, with the child support positioned on top of the base. This nesting arrangement allows the booster seat to achieve variable seating positions through vertical stacking rather than through complex lateral repositioning mechanisms, reducing overall device width and complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The present invention is directed to an adjustable children's booster seat, wherein it comprises a childe support (20) configured for supporting a child, a frame (10) configured for resting on a support surface and suspending the child support (20) above the support surface, wherein the frame (10) comprises a pair of vertically adjustable arms (120) and a pair of upright members (110), wherein each upright member (110) defines a vertical channel, and wherein each vertically adjustable arm (120) is operatively connected to a lateral side of the child support (20) and is positioned at least partially within one of the upright members (110); and one or more height control devices configured to be actuated by a user between a secured configuration and an adjustable configuration, wherein the one or more height control devices permit the vertically adjustable arms (120) to be moved upwardly and downwardly with respect to the frame (10) when in the adjustable configuration and prevent the vertically adjustable arms (120) from moving downwardly with respect to the frame (10) when in the secured configuration.
