Solution Overview

Problem

Existing drain arrangements for modern buildings are cumbersome to install, often require knowledge of the floor type and thickness, and lack efficient and cost-effective solutions for mounting in a quick and secure manner, especially when drain pipes do not extend perpendicularly from the floor.

Innovation Solution

A drain insert arrangement featuring a deformable connector with drain flanges and holders that can be angled or tilted to fit standard drain pipes of varying dimensions, combined with a locking mechanism and adhesive sealing flange for secure mounting, and an optional sensor for leak detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a traditional drain insert is used, then the drain can be mounted in the floor, but the installation process is cumbersome and requires knowledge of floor type and thickness

Engineering Contradiction:
Improveease of installationVSAvoidinstallation complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The drain insert is divided into multiple components: a connector portion that interfaces with the drain pipe, a floor portion that interfaces with the floor, and a valve portion. This segmentation allows each component to be optimized independently and simplifies the overall installation process by enabling modular assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector portion is designed to be movable and adaptable, allowing it to accommodate drain pipes that extend at different angles from the floor. The connector can be adjusted to match non-perpendicular pipe orientations, eliminating the need for precise pre-planning of floor thickness and type.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a drain insert is designed to fit specific floor types, then the seal is reliable, but the device cannot be universally applied to different floor configurations

Engineering Contradiction:
Improveseal reliabilityVSAvoidadaptability to floor types
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connector portion is designed with universal adaptability to interface with various drain pipe configurations and floor types. The movable design allows the same connector to reliably seal against different floor materials and pipe angles, eliminating the need for floor-specific drain insert variants.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The connector's geometric parameters are designed to be adjustable within a range that accommodates different floor thicknesses and pipe angles. This parameter flexibility allows the connector to maintain reliable sealing across diverse installation conditions without compromising seal integrity.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the drain pipe extends non-perpendicularly from the floor, then the installation adapts to existing conditions, but traditional drain inserts cannot be properly mounted

Engineering Contradiction:
Improveadaptability to pipe orientationVSAvoidmounting ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connector portion is designed as a movable component that can be positioned at various angles to match non-perpendicular drain pipe orientations. This dynamic design allows installers to easily mount the drain insert by simply adjusting the connector angle, eliminating complex mounting procedures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of requiring the drain pipe to be perpendicular to the floor for proper installation, the invention inverts the approach by allowing the connector to adapt to the pipe's existing orientation. This reversal of the traditional requirement simplifies mounting in existing buildings where pipe angles vary.

Inventive Principle:
Principle #13The other way round (Inversion)

4Ease of operation

If a valve is mounted in the connector, then water flow can be controlled, but the valve may loosen due to water rising in the drain pipe

Engineering Contradiction:
Improvewater flow controlVSAvoidvalve positioning stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The valve is pre-secured in the connector portion using a retention mechanism that prevents loosening from water pressure. This prior cushioning against the loosening force ensures the valve remains reliably positioned even when water rises in the drain pipe, while maintaining full water flow control capability.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
