Multipurpose highchair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing highchairs have limited functionality, with fixed distances between tray and backrest, and lack adjustability for different age groups and usage needs, limiting their usability as children grow.
Innovation Solution
A multipurpose highchair with adjustable tray, height-adjustable footrest and seat plate, and a rotatable backrest, along with foldable support legs, allowing for customizable configurations to accommodate children of varying ages and needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between the tray and the backrest is fixed in existing highchairs, then the structure is simple and stable, but it becomes difficult for children to use the highchair as they grow bigger
Solution Approach 1:
The patent implements adjustability mechanisms that allow the tray and backrest to change positions dynamically. The tray can be adjusted in the front-rear direction through a locking mechanism with multiple locking ports, and the backrest can be rotated to different angles, transforming the fixed structure into a dynamic one that adapts to children's growth stages.
Solution Approach 2:
The patent changes key geometric parameters of the highchair structure. The distance between the tray and backrest is no longer fixed but can be adjusted by changing the tray's front-rear position and the backrest's rotation angle, allowing the highchair to accommodate children of different sizes and ages.
2Duration of action of stationary object
If the highchair is designed with fixed dimensions, then manufacturing is simple and cost-effective, but the service life is limited as children grow
Solution Approach 1:
By introducing adjustable mechanisms for the tray and backrest, the highchair can be reconfigured as children grow, extending its usable life from a single fixed configuration to multiple stages of child development, thereby significantly increasing the service life.
Solution Approach 2:
The highchair is designed to serve multiple functions across different age groups through its adjustable features. The same highchair can accommodate infants, toddlers, and older children by adjusting the tray position and backrest angle, making it a universal seating solution throughout childhood.
3Adaptability or versatility
If the highchair structure is simplified for ease of manufacture, then production cost is reduced, but the chair cannot meet different usage needs as children grow
Solution Approach 1:
The highchair is divided into independent adjustable modules: the tray assembly with its own positioning mechanism, the backrest with rotation capability, and the support structure. This segmentation allows each component to be manufactured separately using standard processes, then assembled with simple connection mechanisms.
Solution Approach 2:
The segmented design incorporates adjustable features in each module, allowing the tray to move front-rear and the backrest to rotate, providing adaptability to different usage needs while maintaining manufacturing simplicity through modular construction.

AI summary
A multipurpose highchair includes two support legs, two armrests, a footrest, a seat plate, a tray, and a backrest, where each of the armrests corresponds to a support leg, and is provided at a top part of the corresponding support leg; the footrest is height-adjustable, and is provided between the two support legs; the seat plate is height-adjustable, and is provided between the two support legs; the tray is adjustable in a front-rear direction, and is provided between the two armrests; and the backrest is provided between rear ends of the two armrests, and is rotatable relative to the two armrests. The tray is adjustable in the front-rear direction relative to the two armrests, the footrest and the seat plate are height-adjustable relative to the two support legs, and the backrest is angle-adjustable to meet different usage needs.
