Solution Overview

Problem

Existing drainage devices for surface drainage require complex and labor-intensive assembly due to the need for additional sealing measures when connecting multiple units, limiting their flexibility and ease of installation in larger traffic areas.

Innovation Solution

A drainage device with a hollow, elongated base body and a liquid-permeable section forming a one-piece body, featuring standardized pipe connections and a sealing ring for a liquid-tight plug-in connection, allowing for simplified and flexible connection to other drainage devices or standardized pipes without additional sealing measures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If drainage devices are connected using conventional methods, then multiple drainage devices can be assembled together, but the assembly process becomes labor-intensive and requires additional sealing measures

Engineering Contradiction:
Improveconnectivity of drainage devicesVSAvoidassembly effort
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connection element integrates both the connection function and sealing function into a single component. The sealing ring is incorporated directly into the connection element, eliminating the need for separate sealing measures and reducing assembly complexity while maintaining connectivity between drainage devices

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connection element is designed with standardized pipe connections that can connect to both other drainage devices and standardized pipes, providing multi-functional connectivity. This universal design allows the same component to serve multiple connection purposes without requiring different assembly procedures

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

2Reliability

If drainage devices are connected with additional sealing measures, then liquid-tight connections are achieved, but the complexity and time required for installation increase

Engineering Contradiction:
Improveliquid-tight connectionVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The sealing ring is pre-installed and integrated into the connection element during manufacturing. This preliminary action ensures that the sealing function is already in place before installation, eliminating the need for additional sealing measures during assembly and reducing installation time while maintaining liquid-tight connections

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The connection element with integrated sealing ring creates a self-sealing connection through its design. When connected, the sealing ring automatically forms the liquid-tight seal without requiring external sealing materials or additional sealing steps, making the connection process self-sufficient

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If conventional drainage devices are used, then basic drainage function is provided, but the strength and durability are insufficient compared to cast iron construction

Engineering Contradiction:
Improveproduction of drainage devicesVSAvoidstructural strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The drainage device combines the cast iron base body with a plastic connection element and sealing ring. This composite construction leverages the high strength and durability of cast iron for the main structure while using plastic materials for the connection components, achieving both structural integrity and functional connectivity

Inventive Principle:
Principle #40Composite materials
