Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child car safety seat buffering structures, made of foams like EPP, EPS, or EPE, are flammable and compromise impact absorption when replaced with flame-retardant materials, which reduces safety and comfort.
Innovation Solution
A supporting cushion apparatus combining a buffering plate with a fireproof plate, where the fireproof plate has a lower combustion rate and is made of materials like polyethylene, polypropylene, or botanical cotton, attached to the buffering plate to enhance both impact absorption and flame resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional foam materials (EPP, EPS, EPE) are used for buffering structures, then impact absorbing capacity is improved, but flammability increases and combustion rate becomes higher
Solution Approach 1:
The patent applies composite materials by combining foam material (providing impact absorption) with flame-retardant material (providing fire resistance) into a single buffering structure. This composite approach allows the structure to simultaneously achieve both impact absorbing capacity and flame-retardant effect, resolving the contradiction between these two opposing requirements.
2Object-affected harmful factors
If flame-retardant material is used to replace foam in buffering structures, then flammability is reduced, but hardness increases and impact absorbing capacity decreases
Solution Approach 1:
The patent uses composite materials to combine the advantages of both foam material (softness and impact absorption) and flame-retardant material (fire resistance). The composite buffering structure maintains the soft, impact-absorbing characteristics of foam while incorporating flame-retardant properties, thus avoiding the hardness issue associated with using pure flame-retardant material.
3Device complexity
If a single material is used for buffering structure, then device complexity is reduced, but it cannot simultaneously achieve both buffering capacity and flame-retardant effect
Solution Approach 1:
The patent employs composite materials to create a buffering structure that integrates multiple functions into a single component. The composite construction allows the structure to provide both buffering capacity and flame-retardant effect simultaneously, eliminating the need for separate buffering and fire-protection components, thus achieving dual functionality without significantly increasing overall device complexity.
4Strength
If foam density is increased to improve impact absorption, then buffering capacity is improved, but combustion rate increases
Solution Approach 1:
The patent uses composite materials where the flame-retardant component counteracts the increased combustibility that comes with higher foam density. This allows the use of denser foam for improved buffering capacity while the integrated flame-retardant material prevents corresponding increase in combustion rate, thus resolving the contradiction between these two parameters.

AI summary
The present application discloses a fireproof buffering structure (41, 42, 43, 44, 45, 46, 47, 48, 49, 40, 50) which includes a buffering plate (411, 421, 431, 441, 451, 461, 471, 481, 491, 401) and a fireproof plate (412, 422, 432, 442, 452, 462, 472, 482, 492, 402) attached thereto. A combustion rate of the fireproof plate (412, 422, 432, 442, 452, 462, 472, 482, 492, 402) is lower than that of the buffering plate (411, 421, 431, 441, 451, 461, 471, 481, 491, 401). In contrast to conventional buffering structures, the fireproof buffering structure (41, 42, 43, 44, 45, 46, 47, 48, 49, 40, 50) adopts the combined buffering plate (411, 421, 431, 441, 451, 461, 471, 481, 491, 401) and fireproof plate (412, 422, 432, 442, 452, 462, 472, 482, 492, 402). The buffering plate (411, 421, 431, 441, 451, 461, 471, 481, 491, 401) 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 (412, 422, 432, 442, 452, 462, 472, 482, 492, 402) can reduce the combustion rate of the integral structure when catching fire. Therefore, the fireproof buffering structure (41, 42, 43, 44, 45, 46, 47, 48, 49, 40, 50) achieves the purposes of safety and comfort.
