Drain Safety Device Monolithic Stop Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain safety devices are difficult to install, maintain, and replace, and can lead to uncontrolled movement of closure elements, posing safety risks due to the separate and often inaccessible stops used to prevent overturning.
Innovation Solution
A drain safety device with a closure element featuring an integrated angled stop made of the same material, allowing controlled movement between closed and release positions without the need for separate fastening, and using materials like stainless steel or gray cast iron for stability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate stops are attached to the drain body to prevent closure element overturning, then the closure element is secured against uncontrolled movement, but the device becomes difficult to install and maintain due to inaccessible stops
Solution Approach 1:
The stop is integrated directly into the closure element as a monolithic component, combining the closure function and the stopping function into a single piece. This eliminates the need for separate stops that must be attached to the drain body, making installation simple while maintaining the reliability of preventing uncontrolled movement.
2Reliability
If separate stops are used to prevent closure element tipping, then the closure element is secured in position, but the device complexity increases due to additional components and assembly steps
Solution Approach 1:
The stop is formed as an integral part of the closure element, reducing the number of components from multiple separate parts (closure element + separate stops) to a single monolithic component. This simplifies the device structure while maintaining the positioning reliability through the built-in stop feature.
3Ease of operation
If stops are attached from the outside through the drain grate, then the closure element can be controlled, but the operation becomes inconvenient due to limited access
Solution Approach 1:
Instead of attaching the stop to the drain body and accessing it from below through the grate, the stop is inverted and attached directly to the closure element itself. This allows the stop to be accessed and operated from above through the drain grate, making operation convenient while simplifying installation.

AI summary
The invention relates to a drain safety device (100) for at least one drain (101), in particular a floor drain, a yard drain or a street drain, comprising: a locking element (10) for closing and opening the drain (101) and a drain housing (20) for rotatably supporting the locking element (10) on the drain (101), wherein the drain housing (20) has a complementary drain opening (21) for the drain (101), and wherein the locking element (10) is movable between two positions (I, II), in particular rotatably: - a closed position (I), in which the drain opening (21) is closed by the locking element (10), and - a release position (II), in which the drain opening (21) is opened by the locking element (10). For this purpose, it is provided according to the invention that the locking element (10) is mounted on a first surface (O1), which in the closed position (I) of the locking element (10) is aligned with the drain (101).a stop (A1) to secure the locking element (10) against overshooting beyond the closed position (II) when the locking element (10) is moved from the release position (II) to the closed position (I), wherein the stop (A1) is made of the same material, monolithically and/or integrally with the locking element (10).
