Thermal Insulation Tube for Gas Fitting
Solution Overview
Problem
Conventional air compressor fittings connected to air supply tubes experience instability and premature aging due to repeated thermal expansion and contraction caused by high-temperature air, leading to potential leaks and reduced service life.
Innovation Solution
A fitting structure incorporating a thermal insulation tube made of temperature-resistant material, longer than the fitting, which directs high-temperature air from the air compressor through the insulation tube into the air supply tube, reducing thermal impact on the connection site and preventing expansion and contraction issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the fitting connection terminal is directly connected to the air supply tube, then the structure is simple and easy to manufacture, but the connection stability deteriorates due to repeated thermal expansion and contraction from high-temperature air
Solution Approach 1:
The thermal insulation tube is divided into two functional segments: a first end part fixed inside the fitting's second coupling opening, and a second end part extending outward to be received in the air supply tube. This segmentation allows the thermal insulation function to be separated from the connection function, protecting the connection site from high-temperature air while maintaining structural simplicity.
Solution Approach 2:
The thermal insulation tube acts as an intermediary element between the high-temperature air and the fitting connection terminal. It conducts the high-temperature air away from the connection site, preventing direct thermal contact and thereby maintaining connection stability without complicating the overall structure.
2Device complexity
If the fitting connection terminal is directly connected to the air supply tube, then the device complexity is low, but the service life reduces due to aging from high-temperature exposure
Solution Approach 1:
The harmful high-temperature air is extracted from the path between the fitting connection terminal and the air supply tube by using the thermal insulation tube to conduct it directly into the air supply tube. This removes the thermal stress factor that causes aging, extending service life while adding minimal structural complexity.
Solution Approach 2:
The thermal insulation tube provides beforehand protection by conducting high-temperature air away from the connection site before thermal damage can occur. This preventive measure shields the fitting and air supply tube connection from thermal aging, extending their service life without requiring complex protective systems.
3Reliability
If the thermal insulation tube is used to conduct high-temperature air away from the connection site, then the connection stability is improved, but the device complexity increases
Solution Approach 1:
The thermal insulation tube serves multiple functions simultaneously: it provides thermal insulation to protect the connection site, conducts high-temperature air directly into the air supply tube, and structurally connects the fitting to the air supply tube. This multi-functionality improves connection stability without proportionally increasing device complexity.
Solution Approach 2:
The thermal insulation tube merges the insulation function with the air conduction function and the structural connection function into a single integrated component. By combining these functions, the patent achieves improved connection stability without adding separate complex protective mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The thermal insulation tube effectively lowers the temperature of high-temperature air and stabilizes the connection between the fitting and air supply tube, preventing leaks and extending the service life by mitigating thermal expansion and contraction effects.
Implementation Method 1
a thermal insulation tube fixed thereto such that an extended length and a property of temperature resistance of the thermal insulation tube allow air (high-temperature gas) generated and supplied from the air compressor to be directly conducted through the thermal insulation tube
Implementation Method 2
the effect of isolation and extended performance of lowering temperature for the high-temperature air by the thermal insulation tube helps prevent the high temperature from directly applying to a connection site

AI summary
A fitting structure is provided for supply of gas and connectable between an air supply tube in the form of a hose or a plastic pipe and an air outlet of an air compressor and includes a fitting and a thermal insulation tube. The fitting includes a first coupling opening connectable with the air outlet of the air compressor and a second coupling opening connectable with the air supply tube. The thermal insulation tube has a first end part fixed inside the second coupling opening of the fitting and a second end part extending outside the second coupling opening such that a portion of the thermal insulation tube that extends outside the second coupling opening is received in the interior of the air supply tube. High-temperature air from the air compressor is conducted through the thermal insulation tube into the air supply tube without being directly applied to the fitting.
