Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire prevention methods for steel structures, such as fireproof paint, fireproof boards, and wrapping with concrete, are not reliable and fail to achieve effective heat insulation, leading to rapid temperature rises and potential structural damage.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple insulated wools are used to achieve heat insulation, then heat insulation effect is improved, but gaps are produced at connections which worsen fire prevention effect
Solution Approach 1:
The patent applies local quality by adding sealing structures specifically at the connection areas between insulated wools, where gaps are most likely to occur. The sealing structures are not applied uniformly across the entire surface but are strategically placed at critical connection points to seal gaps and prevent flame penetration, thus maintaining fire prevention reliability while preserving the heat insulation effect.
Solution Approach 2:
The patent employs composite materials by combining insulated wools with sealing structures to create a composite fire prevention system. The sealing structures are integrated with the insulated wools at connection points, forming a composite assembly that simultaneously provides both heat insulation and fire prevention functions, eliminating the contradiction between the two effects.
2Reliability
If conventional fire prevention methods (paint, board, concrete) are used, then fire prevention is addressed, but heat insulation is insufficient causing rapid temperature rise
Solution Approach 1:
The patent merges two previously separate functions into a single integrated system: fire prevention and heat insulation. By combining the fire prevention board with insulated wools and sealing structures to form a composite assembly, the system simultaneously provides both fire resistance and thermal insulation, eliminating the need for separate treatments and achieving both objectives concurrently.
Solution Approach 2:
The patent uses composite materials by creating a multi-layered assembly that combines fire prevention boards with insulated wools and sealing structures. This composite structure leverages the fire-resistant properties of the board and the thermal insulation properties of the wools, achieving both fire prevention and heat insulation effects in a single integrated system.
3Reliability
If fireproof paint or fireproof board is applied, then fire prevention is provided, but construction quality dependency reduces reliability
Solution Approach 1:
The patent applies segmentation by dividing the fire prevention system into modular components: fire prevention boards, insulated wools, and sealing structures. Each component can be manufactured and installed independently with standardized procedures, reducing dependency on construction quality. The modular nature allows for easier quality control during manufacturing and simpler installation processes.
