Hemispherical Floor Drain Cover Plate for Hair Blockage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bathroom floor drains are inconvenient to open and prone to hair blockages due to their flush design and lack of handles, making cleaning difficult and inefficient.
Innovation Solution
A floor drain structure featuring a soft elastic cover plate and body with a hemispherical design, a hair collection structure with upright columns, and a regularly polygonal lower end portion with double-line grooves, allowing for easy operation and effective hair winding to prevent blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the floor drain cover plate and body are made flush with the ground, then the drainage and deodorization effects are improved, but the cover plate becomes inconvenient to remove and clean
Solution Approach 1:
The floor drain cover plate is designed as a hemispherical sheet that can be pressed to deform upward, creating a spherical/curved motion path for opening. This curved design allows the cover plate to be easily pressed open without handles, resolving the contradiction between flush mounting and ease of operation.
2Shape
If the floor drain cover plate is made slippery without handles, then the flush design is maintained, but the operation becomes very inconvenient
Solution Approach 1:
The cover plate transitions from a static flush surface to a dynamic element that can be pressed and deformed upward. The hemispherical design enables it to move from a closed flush state to an opened state, maintaining the flush appearance when closed while enabling easy operation when needed.
3Productivity
If the drain holes are left open, then drainage is improved, but hairs block the drain holes easily
Solution Approach 1:
The hair collection structure with upright columns is pre-installed at the lower end of the floor drain body to intercept hairs before they reach the drain holes. This preliminary action prevents blockages while maintaining open drain holes for efficient drainage.
4Ease of repair
If the floor drain body requires removal for cleaning, then complete cleaning is achieved, but the operation becomes complex and time-consuming
Solution Approach 1:
The floor drain system is segmented into a removable cover plate and a fixed body with integrated hair collection structure. This segmentation allows the cover plate to be easily pressed open for access while the body remains in place, simplifying the cleaning operation compared to removing the entire assembly.
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 allows for convenient operation, prevents hair blockages by sealing and easily opening the drain holes, and effectively winds hairs onto the structure, ensuring efficient drainage and easy maintenance without risk of collision damage.
Implementation Method 1
the floor drain cover plate and the floor drain body are made of a soft elastic material

AI summary
A floor drain structure includes a floor drain cover plate and a floor drain body. The floor drain body includes an upper end portion and a lower end portion, the upper end portion of the floor drain body is provided with a first mounting portion at a middle position in an upward extending manner, the floor drain cover plate is movably connected to the first mounting portion, and a hair collection structure is fixedly arranged at the lower end portion of the floor drain body. According to the present invention, the upturned floor drain cover plate can draw the floor drain body out, which is simple in operation and convenient in use; soft material will not cause collision damage to a human body; and a staggered cross bar structure of the present invention can make hairs conveniently wound, avoiding blockage of drain holes.
