Solution Overview
Problem
Existing drinking and process water systems are complex in structure, leading to heavier and more costly installations, and they often fail to maintain water quality effectively, especially in low-use areas where contamination risks are high.
Innovation Solution
A connection device utilizing a pipe-in-pipe system combined with a Venturi effect, where the narrowing of the cross-section creates a pressure difference to induce flow without the need for pumps, ensuring continuous water circulation and quality maintenance through the Venturi effect, even in cold water systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional water system structure is used, then the system is robust and easy to install, but the structure becomes complex and heavy
Solution Approach 1:
The patent implements a pipe-in-pipe system where an inner pipe is nested within an outer pipe to form a ring line. This nesting structure allows continuous circulation flow through the annular space between the pipes, simplifying the overall system architecture while maintaining water quality in previously inaccessible branch lines.
2Reliability
If pumps are used to maintain water flow, then water quality is maintained, but the system becomes more complex and requires additional energy
Solution Approach 1:
The system uses the Venturi effect created by water flow in the main line to automatically generate circulation in the ring line without requiring external pumps. The pressure differential generated by the constriction in the main line self-propels water through the annular space, maintaining water quality through passive circulation.
Solution Approach 2:
The patent utilizes hydraulic principles by employing the Venturi effect - a pressure differential created by fluid flow through a constriction. This hydraulic mechanism drives the circulation system without mechanical moving parts, eliminating the need for pumps while maintaining continuous water movement in the ring line.
3Device complexity
If traditional single pipe systems are used, then the structure is simple, but water quality deteriorates in low-use areas due to contamination
Solution Approach 1:
The patent implements a pipe-in-pipe system where an inner pipe is nested within an outer pipe to form a ring line. This nesting structure allows continuous circulation flow through the annular space between the pipes, simplifying the overall system architecture while maintaining water quality in previously inaccessible branch lines.
Solution Approach 2:
The system ensures continuous circulation of water through the ring line formed by the pipe-in-pipe structure. This continuous flow prevents stagnation and contamination in branch lines that would otherwise be unused, maintaining water quality without requiring active pumping or complex control systems.
4Device complexity
If heavier materials are used to simplify structure, then installation is easier, but material usage and cost increase
Solution Approach 1:
The patent implements a pipe-in-pipe system where an inner pipe is nested within an outer pipe to form a ring line. This nesting structure allows continuous circulation flow through the annular space between the pipes, simplifying the overall system architecture while maintaining water quality in previously inaccessible branch lines.
Solution Approach 2:
The circulation system is segmented into distinct functional zones: the main water supply line, the ring line formed by concentric pipes, and the annular circulation space. This segmentation allows each component to be optimized independently, using standard pipe sizes and materials without requiring oversized or specialized heavy-duty components.

AI summary
The system has an inlet opening (18) connected upstream to a cross-sectional constriction (17) in a flow direction, and an outlet opening (19) connected downstream to the constriction in the flow direction. A pipe-in-pipe line (11) is provided between a load and a line (7). The pipe-in-pipe line is connected with the line by a connection armature. The armature has an inlet connecting piece (21) that is connected with the inlet opening, an outlet connecting piece (22) that is connected with the outlet opening, and a double tube connecting piece (32) that is connected with the pipe-in-pipe line.
