High Chair Side Frame and Tray Assembly for Adjustable Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing juvenile seat designs do not effectively support young children in an elevated position for feeding, and they lack a convenient and adjustable tray system for mealtime use.
Innovation Solution
A high chair assembly with molded plastic side frames that integrate wooden components, including a seat, back, and tray unit, allowing for adjustable positioning and easy assembly, creating a stable and adjustable feeding environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tray unit is made slidable on armrests for adjustable positioning, then ease of operation is improved, but device complexity increases due to additional latches and latch-receiving slots
Solution Approach 1:
The tray unit is designed to be slidable rather than fixed, allowing dynamic repositioning along the armrests. The tray can move between multiple positions and be locked at each position using latches, providing adaptability for different feeding scenarios while maintaining ease of operation.
2Manufacturing precision
If wooden components are used with molded plastic side frames, then manufacturing precision is improved through molding, but ease of manufacture worsens due to integration of multiple materials
Solution Approach 1:
The side frames are constructed using composite materials, specifically molded plastic components that integrate multiple functions. The plastic side frames include built-in latch-receiving slots and armrests, combining structural support, positioning features, and adjustment mechanisms into a single molded component that interfaces with wooden tray and seat components.
3Adaptability or versatility
If latches are made movable to engage latch-receiving slots, then adaptability is improved for different positions, but device complexity increases due to movable latch components
Solution Approach 1:
The latches are designed as movable components that can engage with latch-receiving slots at different positions along the armrests. This dynamic engagement system allows the tray to be securely positioned at multiple locations while maintaining a relatively simple overall structure through the use of standardized latch and slot interfaces.

AI summary
A juvenile seat assembly includes a seat bottom and legs for elevating the seat bottom above the ground to support a child seated on the seat bottom in an elevated position above the underlying ground. In illustrative embodiments, the juvenile seat assembly further includes a seat back arranged to extend upwardly from a rear edge of the seat bottom.
