Child Car Seat Fireproof Buffering Structure for Impact and Flame Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety car seat buffering structures, made of foams like EPP or EPS, are flammable and compromise impact absorption when replaced with flame-retardant materials, necessitating a solution that combines both buffering capacity and flame-retardant effects for enhanced safety and comfort.
Innovation Solution
A child safety car seat design incorporating a fireproof buffering structure with a buffering plate and a fireproof plate, where the fireproof plate has a lower combustion rate, made from materials like polyethylene, polypropylene, or botanical cotton, and is integrated with the buffering plate to provide both impact absorption and reduced flammability, with a thickness of around 12 mm and varying layer configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional foams (EPP, EPS, EPE) are used for buffering structures, then impact absorbing capacity is improved, but combustion rate increases making them flammable and unsafe
Solution Approach 1:
The buffering structure is divided into multiple independent buffering units, each capable of providing impact absorption. This segmentation allows the system to maintain buffering capacity while using smaller, more manageable units that can be strategically positioned throughout the car seat
Solution Approach 2:
The patent uses composite material construction where flame-retardant materials are combined with buffering materials. The buffering units are made from materials that inherently possess both impact absorption properties and flame retardancy, creating a composite structure that achieves both safety requirements simultaneously
2Object-affected harmful factors
If flame-retardant materials are used to replace foams, then combustion rate is reduced, but hardness increases reducing impact absorbing capacity and comfort
Solution Approach 1:
Different regions of the buffering structure have different material properties optimized for their specific functions. The buffering units have softer, more compliant materials for impact absorption, while flame-retardant coatings or layers are applied in specific locations to provide fire protection without compromising the overall buffering performance
Solution Approach 2:
The patent employs composite material systems where flame-retardant materials are integrated with softer buffering materials. This creates a multi-layered or hybrid structure that combines the fire resistance of flame-retardant materials with the impact absorption capabilities of softer materials, achieving both safety requirements without the hardness penalty of using purely flame-retardant materials
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combined structure offers improved safety and comfort by maintaining impact absorption while significantly reducing the combustion rate, ensuring effective protection during crashes and fires.
Implementation Method 1
the fireproof plate is closer to a seating space of the child safety car seat than the buffering plate... a combustion rate of the fireproof plate is lower than a combustion rate of the buffering plate
Implementation Method 2
The buffering plate is a foam plate... The foams have good impact absorbing capacity for effective buffering

AI summary
The present application discloses a child safety car seat having a main body and a fireproof buffering structure disposed on the main body. The fireproof buffering structure includes a buffering plate and a fireproof plate attached to or neighboring to the buffering plate, and the fireproof plate is closer to a seating space of the child safety car seat than the buffering plate. In contrast to conventional child safety car seats, the fireproof buffering structure of the present application adopts the combined buffering plate and fireproof plate. The buffering plate has good impact absorbing capacity for providing a soft and comfortable seating environment and buffering and protection effects during a crash accident, and the fireproof plate can reduce the combustion rate of the integral structure when catching fire. Therefore, the child safety car seat achieves the purposes of safety and comfort.
