Solution Overview

Problem

Conventional height-adjustable child safety seats are expensive, making them less accessible due to high production costs.

Innovation Solution

A safety seat design featuring a separable height-adjusting component with asymmetric portions that can be configured in two height modes, allowing for adjustable height by reversing the position of the component within the seat, thereby reducing production complexity and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional height-adjustable child safety seats are designed with multiple height adjustment mechanisms, then height adaptability is improved, but production cost increases

Engineering Contradiction:

Improveheight adaptabilityVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The height adjusting component is divided into a first portion and a second portion with different heights, allowing the same component to provide multiple height configurations through simple positional reversal rather than requiring multiple complex adjustment mechanisms

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses inversion by allowing the height adjusting component to be installed in two opposite orientations (first portion up or second portion up), where each orientation provides a different height mode, eliminating the need for complex multi-position adjustment mechanisms

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If multiple height adjustment mechanisms are integrated into the safety seat, then height adjustability is improved, but device complexity increases

Engineering Contradiction:

Improveheight adjustabilityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single height adjusting component serves multiple functions by providing both a first height mode and a second height mode through simple positional reversal, eliminating the need for separate adjustment mechanisms for different height configurations

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The component achieves multiple height configurations through inversion of installation orientation rather than through complex mechanical adjustments, significantly simplifying the overall device structure

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A safety seat includes a seat and a height adjusting component that is separably disposed under the seat, and that includes opposite first and second portions, heights of which are different. The safety seat is usable in one of a first height mode and a second height mode. In the first height mode, the first portion is disposed over the second portion, and in the second height mode, the first portion is disposed under the second portion.
