Solution Overview

Problem

Existing devices for high-temperature applications, such as gaskets and seals, lack sufficient heat resistance, which is crucial for safety and performance in environments like vehicle duct systems where fire resistance and durability are essential.

Innovation Solution

A device with improved heat resistance is achieved by incorporating a fabric layer with a ceramic thread seam and a coating barrier, encasing a seal body to form a robust, heat-resistant seal that can withstand temperatures up to 2000 degrees Fahrenheit for at least 15 minutes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a device is used in high-temperature applications, then it can perform its function in hot environments, but it lacks sufficient heat resistance and may fail under extreme temperatures

Engineering Contradiction:
Improveheat resistanceVSAvoiddevice integrity
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The device employs a composite structure consisting of a fabric layer (such as fiberglass) combined with a heat-resistant coating material. This composite construction allows the device to withstand temperatures up to 2000 degrees Fahrenheit for at least 15 minutes, resolving the contradiction between operational temperature requirements and heat resistance by integrating materials with complementary thermal properties.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If existing devices are used without additional protective layers, then the device structure remains simple, but the fire resistance and heat resistance are insufficient

Engineering Contradiction:
Improvefire resistanceVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The invention applies a thin-film coating layer over a fabric substrate to provide fire resistance and heat protection. This approach enhances the device's resistance to harmful thermal factors while maintaining relatively simple construction, as the coating is applied directly to the existing device structure rather than requiring complete redesign.

Inventive Principle:
Principle #30Flexible shells and thin films
