Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow stopping tools for pipelines face issues with hose-balloon connection integrity, leading to potential damage and leakage due to high kinetic forces during inflation, especially at high flow speeds and pressures.
Innovation Solution
Incorporating a shock absorber in the hose-balloon connection, which comprises resilient members like helical springs and sealing rings, to absorb and recoil kinetic forces, enhancing the connection's strength and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the balloon-like element is connected to the pressure rod through a hose without additional strengthening, then the device structure remains simple, but the connection may be damaged by high kinetic forces during inflation at high flow speeds
Solution Approach 1:
The connection part is constructed as a composite structure combining a hose with a reinforcing element (such as a wire braid or mesh) woven or wrapped around it. This composite construction provides enhanced tensile strength and resistance to kinetic forces while maintaining the flexibility and sealing properties of the hose, thereby resolving the contradiction between connection strength and device complexity
Solution Approach 2:
The design incorporates a shock-absorbing element or flexible joint in the hose connection that is pre-configured to absorb and dissipate the kinetic forces generated during balloon inflation. This beforehand cushioning protects the connection from damage without requiring a completely redesigned complex structure, thus improving strength while limiting complexity increase
2Reliability
If the hose is used to inflate and secure the balloon-like element, then the device structure remains simple, but the hose may get damaged resulting in leakage of the inflating medium
Solution Approach 1:
The hose is constructed as a composite material structure with multiple layers including an inner sealing layer, a reinforcing middle layer (such as fabric or wire braid), and an outer protective layer. This composite construction simultaneously improves reliability by preventing leakage and damage while avoiding excessive complexity through integrated manufacturing
Solution Approach 2:
The hose connection part features localized reinforcement at critical stress points (such as where the hose connects to the balloon and pressure rod) through additional layers or stronger materials in those specific areas, while maintaining simpler construction in non-critical sections. This local quality approach improves reliability where needed without unnecessarily increasing overall device complexity

AI summary
A flow stopping tool for pipelines is disclosed, wherein the flow stopping tool comprises an inflatable balloon-like element that is in connection to a pressure rod. A hose is used for inflating the balloon-like element with a gas or a fluid, such that the balloon-like element can block a flow in a pipeline. A first end of the hose is in connection to the pressure rod and a second end of the hose is in connection to the balloon-like element. A part connecting the hose with the inflatable balloon-like element, but outside said balloon-like element, comprises a shock absorber for securing the hose-balloon connection.
