Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional inline surface drains are custom-made to fit a specific riser pipe diameter, then the fitting precision for that specific size is improved, but the adaptability to multiple sizes deteriorates
Solution Approach 1:
The inline surface drain is divided into multiple concentric rings with different diameters that can be selectively removed or retained. This segmentation allows the same drain body to adapt to multiple riser pipe diameters while maintaining precise fitting for each specific size through the appropriate ring configuration.
Solution Approach 2:
The concentric rings are designed to be dynamically removable or adjustable, transforming the static, fixed-size drain into a dynamic, multi-size adaptable structure. This allows the drain to change its effective diameter configuration based on the specific riser pipe size being installed.
2Reliability
If conventional inline surface drains are custom-fabricated for specific riser pipes, then the reliability of connection for that specific size is improved, but the ease of manufacture deteriorates
Solution Approach 1:
A single inline surface drain design serves multiple functions by accommodating different riser pipe diameters through the concentric ring system. This universal design eliminates the need for custom fabrication for each size while maintaining reliable connections through properly selected ring configurations.
Solution Approach 2:
The effective diameter parameter of the drain is changed by selectively removing or retaining different concentric rings. This allows one manufactured component to provide reliable connections for multiple pipe sizes without requiring custom fabrication for each size.
3Stability of the object's composition
If conventional inline surface drains are made to fit specific riser pipes, then the stability of connection is improved, but the device complexity increases
Solution Approach 1:
The concentric rings are segmented into removable and fixed portions, allowing simple removal of specific rings to achieve stable connections for different pipe sizes. This segmentation provides connection stability for multiple sizes without requiring complex adjustable mechanisms.

AI summary
An in-line surface drain may comprise a cylindrical frame and a plurality of concentric rings coupled to the cylindrical frame. The plurality of concentric rings may be configured to protrude outward from a bottom external surface of the cylindrical frame, and the diameters of the plurality of concentric rings may be different. At least one of the plurality of concentric rings may be configured to detachably accommodate a riser pipe.
