Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floor drains for same floor drainage in buildings require floor descent, leading to reduced flow path and drainage area, causing blockages and impaired drainage efficiency.
Innovation Solution
A floor drain design featuring a separable body and cover with a lower accumulated water collection tank, lateral tank, and angled discharge port, along with a support structure to enhance water flow and prevent blockages, allowing for efficient drainage without floor descent, with a large drainage section area and kinetic energy promotion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the floor is descended to achieve same floor drainage, then the drainage can be achieved, but the flow path width and drainage section area are reduced, causing blockage and impeded drainage
Solution Approach 1:
The floor drain is divided into separate functional components: a first collecting tank for receiving water from the first water inlet, a second collecting tank for receiving water from the second water inlet, and a separate discharge structure. This segmentation allows each component to be optimized independently, maintaining adequate flow paths and drainage areas without requiring floor descent.
Solution Approach 2:
The patent utilizes vertical space by stacking the first and second collecting tanks at different heights and positions. The first collecting tank is positioned above the second collecting tank, with water discharged from the first tank into the second tank. This three-dimensional arrangement allows adequate drainage section areas to be achieved without horizontal floor descent.
2Reliability
If the floor is descended to achieve same floor drainage, then the drainage can be achieved, but the flow path becomes narrow, causing blockage
Solution Approach 1:
The flow path is segmented into multiple independent channels: a first flow path from the first water inlet through the first collecting tank, and a second flow path from the second water inlet through the second collecting tank. This segmentation prevents blockage by distributing flow across multiple paths rather than constraining all flow through a single narrow path.
Solution Approach 2:
The first collecting tank is nested above the second collecting tank, with the discharge port of the first tank positioned to discharge into the second tank. This nested arrangement allows adequate flow path widths to be maintained in both tanks while achieving compact vertical integration, avoiding the need for narrow horizontal flow paths that would result from floor descent.
3Ease of manufacture
If the floor is not descended, then the floor structure is preserved, but the drainage area and flow path are insufficient
Solution Approach 1:
The patent transitions from horizontal floor descent to vertical stacking of collecting tanks. The first water inlet is positioned on the top surface of the first collecting tank, and the second water inlet is positioned on the side wall of the second collecting tank. This three-dimensional configuration increases the effective water inlet area without requiring horizontal floor descent, preserving floor structure integrity while achieving adequate drainage area.
4Ease of manufacture
If the floor is not descended, then the floor structure is preserved, but the flow path length is reduced, causing water retention
Solution Approach 1:
The flow path is extended vertically through the stacked tank configuration. Water flows from the first water inlet through the first collecting tank, then vertically downward through the discharge port into the second collecting tank, and finally through the discharge port into the drainage concentrator. This vertical flow path achieves sufficient length for proper drainage without requiring horizontal floor descent, maintaining floor structure integrity while preventing water retention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design improves unobstruction and reduces blockages, ensuring easy maintenance and enhanced sanitary environments by increasing the water inlet area, promoting rapid drainage and preventing water retention, while allowing for non-invasive installation without floor descent.
Implementation Method 1
when surface water enters the accumulated water discharge port, a certain level difference can be formed, and the surface water can directly flow into a drainage concentrator

AI summary
A floor drain for same floor drainage of a building consists of a floor drain body and a floor drain cover The floor drain body consists of a lower accumulated water collection tank, a lateral accumulated water collection tank and an accumulated water discharge port. A bottom of the lower accumulated water collection tank is sealed, and has an angle of 70° to 120° with the lateral accumulated water collection tank. The floor drain cover is a plate with holes, and is divided into a lower upstream face and a lateral upstream face. The lower upstream face of the floor drain cover is located above the lower accumulated water collection tank, and the lateral upstream face of the floor drain cover is located outside the lateral accumulated water collection tank.
