Gassing Element Fixing Plate for Wastewater Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for gassing liquids, such as wastewater, require complex and costly mounting processes involving clips, nuts, and welding, leading to inefficiencies and increased costs.
Innovation Solution
A gassing element with a laterally projecting fixing plate allows for a force-fit connection to the gas supply line, eliminating the need for separate manufacturing and manual mounting, using conventional elements like rivets for a simple and cost-effective assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting methods (clips, nuts, welding) are used to connect the gassing element to the gas supply line, then a secure connection is achieved, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The fixing plate is integrated directly into the gassing element body, merging the connection component with the main element. This eliminates the need for separate clips, nuts, and welding operations, while maintaining secure connection through the integrated plate structure that fits into the gas supply line
Solution Approach 2:
The gassing element is segmented into functional parts: the main gassing body and the integrated fixing plate. This segmentation allows the fixing plate to be designed as a dedicated connection component that simplifies mounting while ensuring reliable attachment to the gas supply line
2Reliability
If separate manufacturing of thread nipples and welding is used to connect the gassing element, then a leak-proof connection is achieved, but manufacturing costs and time increase
Solution Approach 1:
The fixing plate is manufactured as an integral part of the gassing element in one piece, merging what would traditionally be separate components (gassing element body and connection nipple). This eliminates separate manufacturing steps and welding operations while maintaining leak-proof connection through the integrated design
Solution Approach 2:
The fixing plate serves multiple functions: it provides structural support for the gassing element, creates the connection interface with the gas supply line, and ensures leak-proof sealing. This multi-functionality eliminates the need for separate thread nipples and welding operations
3Reliability
If manual preparation and interlocking of nuts and screws is required for mounting, then secure attachment is achieved, but labor costs and mounting time increase
Solution Approach 1:
The fixing plate is designed to be self-aligning and self-securing within the gas supply line. The plate's geometry automatically positions it correctly and secures it without requiring manual preparation, interlocking operations, or specialized tools, thereby maintaining attachment security while dramatically improving mounting speed
4Reliability
If clips are mounted in a specified arrangement on the bottom of the sewage tank, then proper support is achieved, but installation time and costs increase
Solution Approach 1:
The fixing plate design extracts the support function from the tank bottom clips and transfers it to an integrated component on the gassing element itself. This eliminates the need for separate clip installation on the tank bottom, reducing installation time and costs while maintaining support stability through the plate's direct attachment to the gas supply line

AI summary
The invention relates to a device for gassing liquids, particularly waste water, including a gas supply line (1) and at least one gassing element (2), which has a longitudinal axis (L) and can be attached to the gas supply line in a positive manner. In order to simplify the mounting of the gassing element (2), the invention provides that the gassing element (2) has at least one fixing plate (8), which laterally projects relative to the longitudinal axis (L) and which serves to establish a non-positive connection with the gas supply line (1).
