Flush-Mounted Drain Strainer with Hidden Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drain strainers are aesthetically unappealing due to their exposed drain plates and holes, which detract from the interior decoration of kitchens and bathrooms.
Innovation Solution
A drain strainer design featuring a base with a drainpipe and surrounding wall, a drain plate with a central rod recess and multiple drainage holes, and a cover that can be mounted flush with the floor, exposing only a narrow inlet to maintain a clean and appealing appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the drain plate and drain holes are exposed out of the floor, then the drainage function is achieved, but the aesthetic appeal of the interior decoration deteriorates
Solution Approach 1:
The drain plate is nested within the floor surface, with the cover plate covering the exposed portion. The drainage holes are positioned beneath the cover plate, creating a nested structure where the functional component (drain plate) is hidden within the aesthetic component (cover plate), thus achieving both drainage functionality and aesthetic appeal
Solution Approach 2:
The drain strainer is divided into separate components: the drain plate with drainage holes and the cover plate. This segmentation allows the drain plate to perform its drainage function while the cover plate provides the aesthetic appearance, and the two can be independently manufactured and assembled
2Shape
If the cover is added to cover the drainage holes, then the aesthetic appeal is improved, but the ease of cleaning the drain plate deteriorates
Solution Approach 1:
The cover plate is designed to be removable, transforming from a static covering to a dynamic component that can be moved. This allows the cover plate to switch between its aesthetic function (when covering the drain plate) and allows access for cleaning (when removed), thus resolving the contradiction between appearance and maintainability

AI summary
A drain strainer includes a base, a drain plate and a cover. The base includes a drainpipe, a surrounding wall located over the drainpipe, and a connecting portion horizontally connected with the drainpipe and the surrounding wall. The drain plate is mounted in the base and includes a rod recess formed at a center of the drain plate and multiple drainage holes formed through the drain plate. The cover is mounted in the rod recess of the drain plate. The drain strainer can decorate the interior of the kitchen or the bathroom, and is able to filter away dirt or hair easily.
