Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flushing and sampling devices for water house connections are complex and require significant technical effort for installation, with issues such as slower ejection of dirt particles and potential re-deposition due to abrupt flow redirection, necessitating a simpler and more efficient solution.
Innovation Solution
A flushing and sampling device with a Y-shaped design, featuring a flushing pipe body and support body, coaxially aligned connecting flanges compatible with conventional water meter connections, and a hose coupling for efficient flow and discharge, installed between shut-off valves to ensure effective flushing and sampling without undercuts, promoting uniform flow and effective contaminant removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an adapter fitting with a partition is used for flushing, then flushing and emergency supply are enabled, but the rinse water flow is abruptly slowed and redirected causing slower removal of dirt particles or deposition and resuspension of dirt particles
Solution Approach 1:
The patent employs curved pipe sections instead of sharp angles or partitions to redirect the rinse water flow. The curved geometry allows the water flow to transition smoothly from axial direction to radial direction without abrupt changes, maintaining high flow velocity throughout the redirection process and preventing dirt particle deposition.
2Ease of operation
If conventional flushing devices are installed in water service connections, then flushing function is achieved, but the installation requires significant technical effort and complex integration
Solution Approach 1:
The flushing device is designed with universal connection features that allow it to be integrated into existing water service connections without requiring specialized installation procedures. The device can serve multiple functions including flushing, emergency supply, and sampling, reducing the need for separate dedicated systems and simplifying overall installation.
Solution Approach 2:
The device is divided into modular components including connection elements, pipe sections, and functional components that can be assembled separately and then integrated into the water service connection. This segmentation allows for easier handling, installation, and maintenance while reducing the technical effort required for complete system integration.
3Shape
If rinse water is redirected perpendicular to the axis of the pipe-like section, then discharge path is achieved, but the flow velocity is reduced leading to slower dirt particle ejection
Solution Approach 1:
The patent uses curved transition sections with optimized radius to redirect water flow from axial to radial direction. The curved geometry distributes the flow redirection over a longer path, maintaining higher flow velocity compared to sharp perpendicular redirection, thereby preventing dirt particle deposition and ensuring effective ejection.

Function Achieved in This Case
The device enables rapid and uniform flushing, ensuring cleanliness and compliance with legal standards by intercepting thrust forces and maintaining a smooth flow path, facilitating easy installation and reuse while protecting against unauthorized water use.
Implementation Method 1
The flow path through which the flushing water flows within the flushing pipe body is limited by a flushing pipe wall without undercuts
Implementation Method 2
support body extending along a main axis and fixed to the flushing pipe body
