Adjustable height child seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child seats are often too small for growing children, prone to tipping over, and can become soiled with food or other materials, lacking in adjustability and safety features.
Innovation Solution
A height-adjustable child seat design featuring telescoping legs with a releasable latch system, a secure harness with nonporous plastic bands, and a tray that is easy to clean, ensuring stability and adaptability to different table heights while minimizing the risk of injury or soiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size child seat is used, then the seat structure is simple, but the child quickly outgrows the seat
Solution Approach 1:
The patent implements height-adjustable legs with telescoping sections that can be extended or retracted to accommodate growing children. The legs include locking mechanisms that allow the height to be changed between use cycles, transforming the static seat into a dynamic, adaptable structure that grows with the child.
Solution Approach 2:
The leg structure is divided into multiple telescoping sections that can independently adjust in length. This segmentation allows for incremental height adjustments while maintaining structural integrity, enabling the seat to adapt to different child sizes without requiring complete redesign.
2Reliability
If a standard child seat is used, then the manufacturing is simple, but the child can cause the seat to flip or fall out
Solution Approach 1:
The patent employs a wide-based leg configuration that acts as a stabilizing counterweight system. The legs extend outward at angles to create a broader support base, counteracting the tipping forces generated by children shifting or moving in the seat, thereby preventing flips and falls.
Solution Approach 2:
The seat incorporates nonporous plastic materials that provide both structural strength and safety properties. These materials resist breaking under stress while maintaining smooth surfaces that prevent children from catching fingers or falling through gaps, adding multiple safety functions to the structural components.
3Object-affected harmful factors
If a traditional child seat is used, then the structure is simple, but the seat becomes soiled with food or other material
Solution Approach 1:
The patent utilizes nonporous plastic surfaces that form continuous, impermeable barriers against food and liquid penetration. These smooth, non-absorbent surfaces prevent soiling by repelling contaminants, allowing for easy wiping and cleaning without the material becoming saturated with food or other materials.
Solution Approach 2:
The tray is designed as a separate, removable component that can be easily detached from the seat body. This extraction of the most soiling-prone element allows it to be removed for thorough cleaning or replacement, preventing the accumulation of food residues that would otherwise contaminate the entire seat structure.
4Adaptability or versatility
If a fixed-height seat is used, then the structure is simple, but the seat does not adapt to different table heights
Solution Approach 1:
The legs incorporate telescoping sections with locking mechanisms that enable dynamic height adjustment. Each leg can be independently extended or retracted to match different table heights, transforming the static seat into an adaptable system that responds to varying environmental requirements.
Solution Approach 2:
The height-adjustable leg mechanism serves multiple functions: it adapts the seat to different table heights, accommodates growing children over time, and provides stability at each height setting through locking mechanisms. This multi-functionality eliminates the need for separate seats for different height requirements.

AI summary
A height adjustable child seat (10) includes a generally rectangular body (12) which includes a seat recess (18). The child seat is supported by four legs (24) each of which includes an upper leg (26) and a lower leg (32) that extend in telescoping relation. Each leg includes a releasable latch (34) including a positioning projection (36) which is selectively engageable in axially disposed positioning apertures (38). Each leg is in connection with a foot (50) which includes a disc (56) with an overlying tread layer (66). The child seat includes a child holding harness (78) that includes at least one flat plastic band that has smooth surfaces on all sides thereof.
