Floor Drain Assembly with Adjustable Adaptor for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor drain assemblies face challenges in efficiently connecting and securing drain conduits to the floor, particularly in ensuring proper alignment and sealing of strainers and adaptors, which can lead to leaks and inefficiencies in water drainage.
Innovation Solution
A drain assembly comprising a drain conduit, a strainer, and an adaptor that allows for adjustable positioning and secure alignment with the floor, along with a plug for sealing, to facilitate efficient fluid flow and prevent leaks, using materials like PVC for durability and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the drain conduit is rigidly fixed in position, then the alignment stability is improved, but the ease of installation deteriorates due to inability to adjust for misalignment
Solution Approach 1:
The adaptor is designed with movable positioning capabilities, allowing it to be adjusted along the drain conduit before final securing. This dynamic adjustment feature enables installation personnel to accommodate misalignments and achieve proper positioning of the strainer relative to the floor, while maintaining stable alignment once secured.
Solution Approach 2:
The adaptor allows for preliminary positioning and adjustment of the strainer assembly before final fixation to the drain conduit. This preliminary action enables alignment adjustments to be made during installation, ensuring proper positioning is achieved without requiring rigid pre-positioning of all components.
2Reliability
If the strainer is positioned precisely aligned with the floor, then the sealing effectiveness is improved, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The adaptor serves as an intermediary component between the drain conduit and the strainer assembly. It provides adjustable positioning mechanisms that facilitate precise alignment of the strainer with the floor, enabling effective sealing while distributing the complexity of adjustment across a dedicated intermediate component rather than requiring complex integration throughout the entire assembly.
3Ease of operation
If the adaptor is made movable for positioning adjustment, then the ease of installation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The drain assembly is segmented into distinct functional components: the drain conduit, the movable adaptor with positioning adjustment capabilities, and the strainer assembly. This segmentation allows the adaptor to be manufactured as a separate component with specific positioning features, enabling ease of installation through adjustment while allowing manufacturing precision requirements to be managed at the component level rather than requiring perfect precision across the entire assembly.

AI summary
A drain assembly for providing a drain in a floor. The drain assembly includes a drain conduit, a strainer and an adaptor. The drain conduit has an inner surface that defines a fluid flow path and an outer surface. The strainer is disposed above the drain conduit and has openings in fluid communication with the fluid flow path of the drain conduit. The adaptor may be securable in the drain conduit and may be connected to the strainer. Prior to securing the adaptor in the drain conduit, a position of the adaptor in the drain conduit may be moveable to allow atop surface of the strainer to be substantially aligned with the floor. A method of assembly is also disclosed.
