Compact Water Outflow Device with Integrated One-Piece Body and Flexible Inflow Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water outflow devices are bulky due to the need for separate components and external diameters that accommodate additional nuts for leakproof connections, which compromises their compactness and durability.
Innovation Solution
A one-piece design combining a water outflow pipe and body with an insert-and-shackle mechanism, featuring a flexible inflow pipe, axial inflow channel, radial groove, and leakproof O-shape rings, along with a metal cover for enhanced durability and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components with screw nuts are used for connecting pipes and body, then leakproof connection is achieved, but the external diameter of the body must be increased to accommodate additional nuts
Solution Approach 1:
The outflow pipe and body are merged into a single integrated component through injection molding technology. This eliminates the need for separate connection nuts and gaskets, reducing the external diameter while maintaining leakproof performance through an integrated O-shaped ring sealing structure.
Solution Approach 2:
The connection function is extracted from the traditional screw-nut-gasket assembly and replaced with an insert-and-shackle mechanism. The inflow pipe is inserted into the body and secured with a C-shaped shackle, eliminating the need for external nuts and reducing the overall device diameter.
2Reliability
If multiple separate components are used for connection, then leakproofing is achieved through extrusion on gasket, but the device volume becomes larger
Solution Approach 1:
Multiple separate components (body, outflow pipe, connection nuts, gaskets) are merged into fewer integrated components. The outflow pipe and body form a single molded piece, and the inflow pipe connection integrates the insertion hole, shackle, and O-shaped ring into a unified sealing system, significantly reducing device volume.
Solution Approach 2:
The rigid gasket structure is replaced with a flexible O-shaped ring that can deform to seal around the inflow pipe. This flexible sealing element provides effective leakproofing without requiring the bulky extrusion mechanism and thick gaskets of traditional designs.
3Ease of manufacture
If plastic body is used for the device, then manufacturing simplicity is achieved, but the body becomes vulnerable to impact
Solution Approach 1:
The device employs a composite construction where the body is made of plastic for manufacturing simplicity and chemical resistance, while the cover is made of metal for impact resistance and structural strength. This composite approach combines the advantages of both materials to achieve both ease of manufacture and durability.

AI summary
A simple water outflow device which is an outflow device with an inflow pipe and an outflow pipe. The simple water outflow device consists of a body, an inflow pipe, and an outflow pipe. A discharge control valve is installed inside the body. The outflow pipe and body are a one-piece design created using injection molding technology. The inflow pipe is soft and flexible. There is an axial inflow channel and radial groove inside the body. The groove and the inflow channel are perpendicularly connected. There is a circular magazine on the upper end of the inflow pipe. A leakproof O-shape ring is placed on the circular magazine. The upper end of the inflow pipe is inserted into the inflow channel. A C-shape shackle is inserted into the groove of the body, and shackled into the circular magazine of the inflow pipe. This secures the inflow pipe on the body.
