Adjustable Floor Drain Support Plate for Corrugated Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor drain installation methods are limited by the inability to adjust the height of the drain without modifying or replacing the block, and they are inefficient on corrugated surfaces, requiring increased installation time and concrete chiseling.
Innovation Solution
A drain support plate with a body having a first portion and a second portion, where the first portion defines a peripheral edge and a center passageway, and the second portion extends axially from the first portion, allowing for adjustable installation on both flat and corrugated surfaces by using slots and elongated members to secure the receptacle body and pipe connection, enabling level adjustment and secure attachment to the floor structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a block is used to support the floor drain during installation, then the drain can be positioned in the floor structure, but the height between the drain and the board cannot be adjusted without cutting or replacing the block
Solution Approach 1:
The support plate incorporates adjustable legs that can be extended or repositioned to change the height of the drain assembly relative to the board. This dynamic adjustment mechanism allows the height to be modified without cutting or replacing the support structure, resolving the contradiction between height adaptability and installation complexity.
Solution Approach 2:
The support plate is divided into separate components including an adjustable leg mechanism that can be independently positioned. This segmentation allows the height adjustment function to be isolated from the main support structure, enabling height changes without affecting the overall structural integrity or requiring complex cutting operations.
2Reliability
If concrete is poured around the receptacle body and block, then the floor drain is secured in position, but the block must be chiseled away from the concrete increasing installation time
Solution Approach 1:
The adjustable legs are designed to extend beyond the concrete pour area, allowing the drain assembly to be secured to the board before concrete is poured. This extraction of the adjustment mechanism from the concrete-embedded portion eliminates the need to chisel away blocked legs, reducing installation time while maintaining positioning stability.
Solution Approach 2:
The support plate allows height adjustment and positioning to be completed before the concrete is poured. This preliminary action ensures the drain is correctly positioned and secured to the board prior to concrete placement, eliminating the need for post-pour chiseling operations and reducing overall installation time.
3Adaptability or versatility
If a support plate is used to adjust height, then the drain height can be modified, but the support plate is not easily adapted for use on floor structures having a corrugated surface
Solution Approach 1:
The support plate incorporates a corrugated surface portion that matches the geometry of corrugated floor structures, while also being compatible with flat surfaces. This universal design allows the same support plate to be used on both corrugated and flat floor structures without requiring different components, resolving the contradiction between surface type compatibility and manufacturing simplicity.
Solution Approach 2:
The support plate has different surface characteristics tailored to specific applications - a corrugated surface portion for corrugated floors and a flat portion for flat floors. This local quality differentiation allows the support plate to adapt to different surface types while maintaining a relatively simple overall manufacturing process.
4Manufacturing precision
If the block is chiseled away to create a void, then the drain can be properly positioned, but the wire and nails must be trimmed and the process is time-consuming
Solution Approach 1:
The adjustable legs are extracted from the concrete-embedded portion and positioned to extend beyond the concrete pour area. This allows the drain assembly to be secured to the board before concrete is poured, eliminating the need to chisel away blocked legs and trim embedded wires and nails, thereby reducing installation time while maintaining positioning precision.
Solution Approach 2:
The support plate enables all positioning and securing actions to be completed before the concrete is poured. This preliminary action includes adjusting the drain height, securing it to the board, and positioning it in the floor opening, thereby eliminating the need for post-pour chiseling and trimming operations that consume significant installation time.

AI summary
A floor drain support plate for mounting and securing a floor drain to a floor structure includes body having a peripheral edge, an interior cavity and a center passageway spaced radially apart from the peripheral edge and adapted to receive a pipe. The body of the support plate defining at least one slot adapted to be aligned with the floor drain for receiving a member for attaching the floor drain to the body of the support plate. A flange is attached to the body of the support plate and extends away from the interior cavity, the flange defining at least one flange slot adapted to receive a fastener, and two opposed elongated members or wing sections extending from said flange.
