Innovation Solution
An aerator assembly featuring a flexible body with a compression mechanism using a screw and nut arrangement, allowing reversible activation and deactivation to securely clamp and seal the aerator to the gas supply conduit, eliminating the need for additional seals and accommodating varying pipe wall thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded pipe connection piece is welded onto the gas supply conduit, then the aerator can be attached securely, but the attachment becomes complicated and the price of the holder and system increases
Solution Approach 1:
The attachment means is divided into separate components: a holder with an outer chamber and a connection piece that attaches to the gas supply conduit. This segmentation allows the connection piece to be a simple, standardized component while the holder remains modular and replaceable, reducing overall system complexity while maintaining secure attachment.
Solution Approach 2:
The connection piece serves multiple functions: it provides a secure mechanical attachment point, creates a sealed interface, and allows for easy detachment and reattachment. This multi-functionality eliminates the need for complex specialized components, simplifying the overall attachment system while ensuring reliable connection.
2Device complexity
If pipe clamps are used to attach the aerator, then the attachment can be simplified, but the holder and system price increases
Solution Approach 1:
The attachment means merges the holder structure with an integrated connection piece that functions as both a mounting interface and a sealing element. This consolidation eliminates the need for separate clamps or additional sealing components, reducing manufacturing costs while maintaining attachment simplicity.
3Device complexity
If the aerator is glued to the pipe wall, then the attachment is simple, but the glue joint becomes hard and brittle and damages under high forces during installation
Solution Approach 1:
The connection piece acts as an intermediary between the holder and the gas supply conduit, providing a mechanical interface that distributes forces evenly. This intermediary structure eliminates the need for brittle glue joints while maintaining simple attachment procedures, as the connection piece can be securely fastened with standard fastening methods that accommodate installation forces.
4Reliability
If the aerator loosens during installation, then the attachment fails, but reattachment is difficult as controlled environment and fixtures are required for optimal gluing
Solution Approach 1:
The connection piece is designed to be self-contained with integrated sealing elements and a standardized interface that allows workers to attach and detach aerators using basic tools and skills. The design includes self-aligning features and simple fastening mechanisms that do not require controlled environments or specialized fixtures, enabling easy reattachment in field conditions.
5Ease of manufacture
If a pop rivet is used for joining, then the aerator can be attached, but there is a great risk of leakage at the interface requiring multiple seals
Solution Approach 1:
The connection piece merges the mechanical fastening function with an integrated sealing system. The design incorporates sealing elements directly into the connection structure, creating a single-component solution that provides both secure attachment and leak-proof sealing, eliminating the need for multiple separate seals while maintaining ease of installation.
6Ease of operation
If the pop rivet is destroyed to detach the aerator, then the aerator can be exchanged, but the gas supply conduit and aerator may be damaged
Solution Approach 1:
The attachment system is segmented into removable components, with the connection piece designed as a separate element that can be detached without affecting the integrity of the holder or gas supply conduit. This segmentation allows the aerator to be exchanged by simply removing the connection piece, eliminating the need to destroy or damage any components.
7Strength
If a stiff pop rivet is deformed by external forces, then leakage occurs despite the seal at the interface
Solution Approach 1:
The connection piece incorporates flexible sealing elements that can accommodate external forces and deformations without compromising the seal. These flexible components absorb mechanical stresses and maintain the sealing interface integrity even when subjected to installation forces or thermal expansion, preventing leakage while maintaining attachment strength.
