Solution Overview

Problem

Existing fire protection materials are highly specialized for fire protection purposes but lack versatility in meeting other structural requirements, such as thermal insulation, and are often difficult to mount and adapt for various applications.

Innovation Solution

A lightweight insulating material is developed using a high-temperature-resistant phosphate ceramic as a support structure, combined with lightweight building materials like expanded polystyrene, which provides both thermal insulation and fire resistance, and can be easily shaped and attached using a curable mixture that forms a cohesive shell or lattice structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If special fire protection materials are used, then fire resistance is improved, but thermal insulation performance deteriorates and structural versatility is limited

Engineering Contradiction:
Improvefire resistanceVSAvoidthermal insulation and structural support capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a composite material combining phosphate ceramic granules (fire protection component) with polyurethane foam (thermal insulation component). This composite structure allows both materials to contribute their respective properties: the phosphate ceramic provides fire resistance while the polyurethane foam provides thermal insulation, resolving the contradiction between fire protection specialization and thermal insulation performance

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The resulting composite material serves multiple functions simultaneously: it provides fire protection, thermal insulation, and structural support capability. The material can be applied to various substrates including walls, ceilings, and structural components, making it versatile for different construction applications while maintaining both fire safety and thermal efficiency

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of energy

If lightweight building materials are used for thermal insulation, then thermal insulation performance is improved, but fire resistance deteriorates

Engineering Contradiction:
Improvethermal insulation efficiencyVSAvoidfire resistance
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent combines lightweight polyurethane foam (excellent thermal insulator) with phosphate ceramic granules (fire-resistant material). The polyurethane foam matrix provides superior thermal insulation with low energy loss, while the distributed phosphate ceramic granules throughout the matrix provide fire resistance, simultaneously achieving both thermal efficiency and fire safety

Inventive Principle:
Principle #40Composite materials

3Strength

If phosphate ceramic is used as support structure, then fire resistance and structural strength are improved, but ease of shaping and mounting deteriorates

Engineering Contradiction:
Improvehigh-temperature resistance and structural supportVSAvoidshaping and mounting effort
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent utilizes the temperature-dependent properties of the phosphate ceramic-polyurethane composite. At room temperature, the material remains soft and pliable, allowing easy shaping and mounting. When exposed to fire or high temperatures, the polyurethane carbonizes and the phosphate ceramic strengthens, providing structural support. This parameter change with temperature resolves the contradiction between ease of manufacture and high-temperature strength
