Metal-Reinforced Plastic Pipe Coupling for High-Temperature Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plastic fluid pipes used in heating and air conditioning units face instability at high temperatures and pressures, leading to potential disconnection issues with quick connectors due to the lack of sufficient stability in the plastic bead used for connection.
Innovation Solution
A plastic fluid pipe with a metal or metal alloy ring encasing a plastic bead around the pipe coupling section, enhancing stability under thermal and mechanical stress, particularly using an aluminum or aluminum alloy ring with a U-shaped cross section that matches the bead, ensuring secure connection at high temperatures and pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic bead is used for connection in the pipe coupling section, then the pipe can be produced with simple manufacturing processes, but the connection stability deteriorates at high temperatures and pressures
Solution Approach 1:
The pipe coupling section combines plastic and metal materials to create a composite structure. The plastic bead provides ease of manufacturing and sealing, while the metal reinforcement embedded in the bead provides mechanical strength and connection stability under high temperature and pressure conditions, resolving the contradiction between manufacturing simplicity and connection reliability.
Solution Approach 2:
Instead of making the entire pipe coupling section from metal, the invention applies metal reinforcement only in the critical bead area where connection stability is needed. This localized reinforcement maintains manufacturing simplicity while improving reliability at the specific location where it is most needed.
2Reliability
If precision manufacturing is used to improve bead stability at high temperatures and pressures, then connection reliability improves, but manufacturing complexity and cost increase
Solution Approach 1:
The invention uses composite materials (plastic bead with metal reinforcement) to achieve high connection stability through material properties rather than complex precision manufacturing. The metal reinforcement inherently provides the necessary stability at high temperatures and pressures without requiring complex manufacturing processes.
Solution Approach 2:
The invention changes the material parameters of the bead by incorporating metal reinforcement, which fundamentally alters the thermal and mechanical properties of the bead. This parameter change enables the bead to maintain stability at high temperatures and pressures without requiring precision manufacturing tolerances.

AI summary
A fluid pipe for a heating and air conditioning unit, exhibiting a pipe coupling section produced at least predominantly from plastic in the area of a mouth of the pipe, wherein a bead that is constructed from plastic and runs around the circumference of the pipe in the pipe coupling section and protrudes outward and wherein a circumferential ring that also runs around the circumference of the pipe and is produced from metal or a metal alloy is attached to the bead.
