Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fireproof and thermal insulation solutions for aircraft and helicopters are either expensive, heavy, lack rigidity, or fail under vibration, making them unsuitable for structural applications and prone to collapse during manufacturing or assembly.
Innovation Solution
A fireproof and thermal insulator product combining Alkaline Earth Silicate (AES) material with a liquid barrier film and cork, where the cork is either stacked on top of the AES or configured in a grid structure embedded within it, along with a Fibre Reinforcement Plastic (FRP) layer, providing both fireproof and thermal insulation while being lightweight and cost-effective.
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 and thermal insulation are prevented, but the solution becomes expensive and heavy
Solution Approach 1:
The patent applies composite materials by combining AES (Alkaline Earth Silicate) with cork and FRP (Fibre Reinforcement Plastic) layers. This composite structure provides fireproof and thermal insulation capabilities while being lighter and more cost-effective than traditional ceramic or silicone laminates with aluminum sheet.
2Temperature
If thermal blankets are used for thermal insulation, then thermal insulation capability is provided, but the material lacks rigidity and collapses during manufacturing or assembly
Solution Approach 1:
The patent combines soft thermal insulation material (cork) with rigid FRP layers to create a composite structure. The FRP layers provide the necessary rigidity and structural support during manufacturing and assembly, while the cork core maintains thermal insulation capability. This composite approach resolves the contradiction between softness for insulation and rigidity for structural integrity.
3Reliability
If fire-resistant materials like titanium, steel or Inconel are used instead of conventional structural materials, then fire penetration capability is improved, but cost and weight increase
Solution Approach 1:
The patent replaces heavy fire-resistant metals like titanium, steel, or Inconel with a composite material system consisting of AES, cork, and FRP. This composite provides comparable or superior fireproof capability while significantly reducing weight and cost, making it suitable for applications where weight is a critical factor such as aircraft and helicopter structures.
4Reliability
If fire-resistant materials like titanium, steel or Inconel are used instead of conventional structural materials, then fire penetration capability is improved, but the solution becomes expensive
Solution Approach 1:
The patent replaces expensive fire-resistant metals with a composite material system using AES, cork, and FRP. These materials are more cost-effective while providing equivalent or better fireproof performance. The composite structure also allows for easier manufacturing and integration into existing structures, reducing overall production costs.
5Strength
If conventional structural materials like aluminium or composite are used in fire-zone areas, then structural requirements are met, but the materials lack high-temperature strength capability
Solution Approach 1:
The patent segments the structural system into distinct functional layers: conventional structural materials (aluminum or composite) for mechanical strength, and a fireproof/thermal insulation product (AES-cork-FRP composite) for high-temperature protection. This segmentation allows each material to perform its specialized function, with the structural material providing strength and the composite layer providing thermal protection.
Solution Approach 2:
The patent uses a composite fireproof layer (AES-cork-FRP) that can be integrated with conventional structural materials. This composite material provides high-temperature strength capability while allowing the underlying structural material to maintain its mechanical strength, creating a multi-functional system that addresses both structural and thermal requirements.
