Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid connection arrangements in vehicles require complex calibration and high deformation forces, leading to risks of metal particle detachment and contamination, and often fail to provide a reliable, fluid-tight connection under high pressure.
Innovation Solution
A fluid connection arrangement featuring a receiving part with a receiving wall and a tubular connecting part having comb-shaped support points and curved wall areas, where solder is used to create a materially bonded and fluid-tight connection between the parts, reducing deformation forces and manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional calibration is carried out by means of a flanging machine to reduce the outer diameter of the pipe end, then the gap width during soldering is ensured, but high deformation forces occur and metal particles may detach
Solution Approach 1:
The patent extracts the calibration function from the flanging machine process and integrates it into the connection geometry itself. The connection geometry is designed with a predetermined gap width that automatically ensures proper spacing during soldering, eliminating the need for separate calibration operations that cause metal particle detachment.
Solution Approach 2:
The gap width is predetermined during the manufacturing of the connection geometry, before the actual assembly and soldering processes. This preliminary determination of the gap width eliminates the need for subsequent calibration operations that would otherwise be required to ensure proper spacing.
2Manufacturing precision
If conventional calibration is carried out by means of a flanging machine, then the gap width during soldering is ensured, but the workpieces must be cleaned and degreased prior to soldering
Solution Approach 1:
The patent extracts the gap width control function from the complex cleaning and degreasing process. By designing the connection geometry with a predetermined gap width, the invention eliminates the need for separate calibration, cleaning, and degreasing operations, simplifying the overall manufacturing process.
3Reliability
If solder is used to create a materially bonded connection, then a fluid-tight connection is achieved, but the connection must withstand high pressure loads
Solution Approach 1:
The patent employs a composite connection structure combining solder material with a specifically designed connection geometry. The connection geometry features a predetermined gap width that, when filled with solder, creates a composite structure capable of withstanding high pressure loads while maintaining fluid-tightness. The comb-shaped support points provide structural reinforcement to the solder joint.
4Stability of the object's composition
If the tubular connecting part is received in the receiving part, then a stable connection is achieved, but the comb-shaped support points must contact the receiving wall inner side
Solution Approach 1:
The patent applies local quality by designing comb-shaped support points with specific contact characteristics. These support points have a localized comb-like structure that provides stable contact with the receiving wall inner side at specific locations, while the overall connection geometry maintains ease of manufacture through its predetermined gap width and modular design.

Function Achieved in This Case
The solution ensures a stable, easy-to-manufacture, and fluid-tight connection that withstands high pressure loads with reduced manufacturing effort and eliminates the need for flanging machines and lubrication, preventing twisting and detachment of the tubular connecting part.
Implementation Method 1
