Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
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
