Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire protection solutions for aircraft, such as thermal blankets and materials with porous charred layers, are either expensive and heavy, lack rigidity, or fail under vibration, and conventional fire-resistant materials like titanium are costly and require replacement post-fire.
Innovation Solution
A fireproof and thermal insulation laminate combining alkaline Earth Silicate (AES) material with a liquid barrier film, Fiber Reinforcement Plastic (FRP) layer, and cork, which provides low-cost, lightweight, and environmentally friendly protection with enhanced rigidity, suitable for structural integration and maintaining insulation under high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal blankets made of ceramic or silicone laminates with aluminum sheet are used, then flame penetration suppression and thermal insulation are improved, but weight and cost increase, and rigidity is lost causing collapse during manufacturing or assembly
Solution Approach 1:
The patent uses a composite structure consisting of a fire-resistant core material (such as ceramic matrix composite or refractory concrete) combined with a rigid outer shell (such as metal or composite panel). This composite design provides both flame penetration suppression and rigidity, while the rigid shell prevents collapse during manufacturing and assembly, unlike flexible thermal blankets
Solution Approach 2:
The patent applies a thin fire-resistant coating or liner (such as intumescent coating or fire-resistant membrane) on the inner surface of the rigid structure. This thin film provides flame penetration suppression and thermal insulation without adding significant weight, while the underlying rigid structure maintains structural integrity and prevents collapse
2Reliability
If materials creating porous charred layer are used, then flame penetration prevention and insulation are improved, but protection is lost under vibration conditions
Solution Approach 1:
The patent combines a rigid fire-resistant material (such as ceramic matrix composite, refractory concrete, or metal alloy) with a porous insulating material (such as ceramic foam or intumescent coating). The rigid component maintains structural stability and protection under vibration, while the porous material provides flame penetration prevention and thermal insulation
Solution Approach 2:
The patent applies different materials with different properties to different parts of the structure: a rigid, vibration-resistant fire-resistant material is used in areas subject to vibration, while porous insulating materials are used in areas where vibration is minimal. This localized approach ensures both flame penetration prevention and stability under vibration conditions
3Reliability
If fire-resistant materials like titanium, steel or Inconel are used instead of conventional materials, then fire penetration suppression is improved, but cost increases and replacement is required after fire event
Solution Approach 1:
The patent uses a composite structure where a relatively thin fire-resistant barrier (such as ceramic matrix composite or refractory lining) is combined with a structural support system. This approach provides fire penetration suppression comparable to titanium or steel but at lower cost, and the modular design allows for easier replacement after fire events without replacing entire structural components
Solution Approach 2:
The patent divides the fire protection system into separate modular components: a replaceable fire-resistant liner or barrier, and a permanent structural support framework. This segmentation allows the fire-resistant component to be replaced after a fire event without replacing the entire structure, reducing overall cost and simplifying maintenance
