Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors in fluid systems, such as those used in SCR systems, face issues with resistance to line pressures and the risk of plastic deformation or failure due to freezing fluids expanding within the connector.
Innovation Solution
The connector incorporates a resistance element within the recording body that limits further elastic deformation of the absorption body, providing additional resistance to pressure and preventing plastic deformation by maintaining the elastic area even under high pressures or freezing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the receiving body is made elastically deformable to absorb pressure forces, then the connector can withstand line pressures and freezing expansion forces, but the receiving body may undergo plastic deformation or failure under excessive forces
Solution Approach 1:
The patent introduces a resistance element that changes the mechanical parameters of the receiving body by providing progressive resistance during deformation. The resistance element modifies the force-displacement characteristics, creating different resistance levels in different displacement ranges while maintaining elastic deformation throughout, thus preventing plastic deformation under excessive forces.
Solution Approach 2:
The resistance element acts as a pre-designed protective mechanism that engages before plastic deformation can occur. By providing progressive resistance during elastic deformation, it cushions the receiving body against excessive forces that would otherwise cause permanent damage or failure.
2Stability of the object's composition
If the receiving body is designed with high elastic deformability to compensate for pressure pulsations, then the connector can absorb pressure fluctuations, but the device complexity increases
Solution Approach 1:
The resistance element is integrated directly into the receiving body structure, merging the pressure compensation function with the structural component. This integration allows the receiving body to provide both structural support and pressure pulsation compensation through its elastically deformable design with built-in progressive resistance.
3Ease of manufacture
If the receiving body is made rigid to maintain structural integrity, then manufacturing is simpler, but the connector cannot compensate for pressure pulsations and freezing forces
Solution Approach 1:
The receiving body is designed with controlled elastic deformability by modifying its structural parameters (wall thickness, geometry, material properties) to achieve the desired balance between manufacturing simplicity and pressure compensation capability. The resistance element further refines this by providing progressive resistance during deformation.

Function Achieved in This Case
This design enhances the connector's resistance to line pressures and protects against overload, preventing plastic deformation and ensuring the connector remains functional even under extreme conditions such as high pressures or freezing fluids.
Implementation Method 1
The receiving body (4) is designed to be elastically deformable in such a way that the contact surface (42) is elastically displaceable at least within a displacement range against the insertion direction (E)
Implementation Method 2
When the contact surface (42) is displaced beyond the displacement range, the resistance element (69) generates resistance against further elastic deformation of the receiving body (4)

AI summary
The present invention relates to a plug-in connector (1) for producing hose connections and/or pipe connections, comprising a basic body (2) and a receiving body (4) which each have a plug-in channel (6, 8) for a plug part (10) which is to be mounted in a plug-in direction (E), and further comprising a holding part (28) which is arranged in a receiving opening (26) of the receiving body (4) and, in a locking position, blocks the plug part (10) to be mounted counter to the plug-in direction (E). The receiving body (4) is connected to the basic body (2), and the holding part (28) has a stop surface (40) facing counter to the plug-in direction (E). The receiving opening (26) has a bearing surface (42) facing in the plug-in direction (E), wherein, with a displacement of the holding part (28) counter to the plug-in direction (E), the stop surface (40) acts against the bearing surface (42) of the receiving body (4). The receiving body (4) is designed to be elastically deformable in such a way that the bearing surface (42) is elastically displaceable at least within a displacement region counter to the plug-in direction (E). The receiving body (4) has a resistance element (69) which, with a displacement of the bearing surface (42) beyond the displacement region, produces a resistance to a further elastic deformation of the receiving body (4) counter to the plug-in direction (E).
