Flush-Face Cartridge Coupling for ISO 16028 Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick cartridge couplings are limited in versatility as they can only connect with Standard ISO 7241-compliant male couplings, restricting their application in the agricultural field, where ISO 16028-compliant flush-face couplings are also needed.
Innovation Solution
A female cartridge coupling designed to be inserted into a support block, enabling connection with Standard ISO 16028-compliant male couplings, featuring a push-pull connection system, break-away functionality, and a pressure discharge system, along with a mechanical lock for secure connection and pressure management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cartridge coupling is designed according to Standard ISO 7241, then it can connect with standard agricultural male couplings, but it cannot connect with flush-face male couplings (Standard ISO 16028)
Solution Approach 1:
The cartridge coupling is designed with a universal interface that can accommodate both Standard ISO 7241 and Standard ISO 16028 male couplings. The coupling structure includes a receiving space with a front face that can interface with different coupling types, and a sealing element that can seal against various male coupling configurations, enabling one female coupling to serve multiple functions
2Ease of operation
If the cartridge coupling is integrated into the support block with non-axial flow, then the flow is directed radially through the manifold, but the coupling cannot be disconnected in the presence of residual pressure
Solution Approach 1:
The decompression system includes a decompression valve and decompression channel that can be activated before disconnection to release residual pressure from the coupling. This preliminary action of pressure release enables safe disconnection of the male coupling from the female cartridge even when the system previously contained residual pressure
3Ease of operation
If the cartridge coupling includes a decompression system at the back, then residual pressure can be released, but the connection system lacks mechanical lock during connection
Solution Approach 1:
The mechanical locking system is integrated into the connection mechanism by combining the locking element with the valve body or inner body structure. The locking element works together with a locking groove to provide automatic mechanical locking during the connection process, securing the male coupling to the female cartridge without requiring separate locking components

AI summary
The present invention relates to a female cartridge coupling of the type suitable for being inserted into a support block, or manifold, which is connectable to a pressurized oil circuit on board the machine. The female cartridge coupling in accordance with the present invention is characterized in that although it is configured to be inserted into a support block, it is suitable for being connected to Standard ISO 16028-compliant flush-face male couplings. The cartridge in accordance with the present invention further comprises a system for mechanically locking the decompression valve which allows the connection of a male coupling.
