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, integrated with the buffering plate to provide both impact absorption and flame retardancy.
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 combustion rate increases making the material flammable
Solution Approach 1:
The patent applies composite materials by combining foam material (for impact absorption) with flame-retardant material (for fire resistance) into a single integrated buffering structure. This composite approach allows the structure to simultaneously achieve both impact absorbing capacity and low combustion rate, resolving the contradiction between safety from crashes and safety from fire.
2Object-affected harmful factors
If flame-retardant material is used to replace foam, then combustion rate is reduced, but hardness increases reducing impact absorbing capacity and comfort
Solution Approach 1:
The patent applies local quality by having different regions of the buffering structure possess different material properties. The flame-retardant material is strategically positioned in specific areas (such as outer layers or strategic zones) to provide fire resistance, while foam material is retained in areas where impact absorption is most critical. This localized differentiation allows each material to perform its optimal function without compromising overall performance.

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 integrated fireproof buffering structure enhances safety and comfort by maintaining impact absorption while reducing the overall combustion rate, ensuring effective protection during crashes and in case of fires.
Implementation Method 1
A combustion rate of the fireproof plate is lower than a combustion rate of the buffering plate
Implementation Method 2
The foams have good impact absorbing capacity for effective buffering

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. The present application further discloses a supporting cushion apparatus (1) which includes a covering member (11) and the aforementioned fireproof buffering structure (41, 42, 43, 44, 45, 46, 47, 48, 49, 40, 50) accommodated therein. The present application further discloses a safety seat (8, 3) which includes the aforementioned fireproof buffering structure (41, 42, 43, 44, 45, 46, 47, 48, 49, 40, 50) and the supporting cushion apparatus (1).
