Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sealed connections between components require time-consuming and costly machining processes, alignment adjustments, and are prone to damage during assembly, particularly for fluid transfer in brake systems.
Innovation Solution
A connecting device with a pipe portion and a sealing element featuring inflow and outflow regions that extend beyond the pipe ends, allowing fluid flow transverse to the pipe's extent, and a mirror-symmetrical design with positioning projections and recesses for easy alignment and secure fixation, ensuring a sealed connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional groove machining and O-ring insertion methods are used for sealed connection, then sealing function is achieved, but manufacturing time and cost increase significantly
Solution Approach 1:
The invention extracts the sealing function from the traditional groove-O-ring assembly and integrates it directly into the pipe end geometry. The sealing element is built into the pipe end structure itself, eliminating the need for separate groove machining and O-ring installation steps, thus reducing manufacturing time while maintaining sealing reliability.
Solution Approach 2:
The invention merges the sealing function with the pipe end structure by integrating the sealing element directly into the pipe end geometry. This consolidation eliminates separate components and assembly steps, reducing both manufacturing complexity and time while ensuring reliable sealing through the integrated design.
2Reliability
If groove machining is performed for sealing element installation, then sealing connection is achieved, but manufacturing cost increases
Solution Approach 1:
The invention extracts the sealing function from expensive groove machining operations and implements it through the integrated pipe end geometry. This eliminates the need for precision groove machining and separate O-ring installation, significantly reducing manufacturing costs while maintaining reliable sealing connection through the built-in sealing element design.
Solution Approach 2:
The invention merges the sealing function with the pipe end structure, eliminating the need for separate groove machining operations. This integration reduces manufacturing steps and costs while ensuring reliable sealing through the consolidated design that combines structural and sealing functions in one element.
3Ease of operation
If additional sleeve or pin is introduced for alignment, then component alignment is achieved, but device complexity increases
Solution Approach 1:
The invention extracts the alignment function from separate sleeves or pins and integrates it directly into the pipe end geometry. The built-in sealing element and pipe end structure provide inherent alignment features that guide component assembly without requiring additional alignment components, thus reducing device complexity while maintaining ease of alignment during assembly.
4Reliability
If traditional connection methods are used, then sealed connection is achieved, but risk of O-ring damage during assembly increases
Solution Approach 1:
The invention extracts the sealing element from the traditional O-ring component and integrates it directly into the pipe end structure. This eliminates the O-ring as a separate installable component, removing the risk of O-ring damage during assembly while maintaining reliable sealed connection through the integrated sealing element that is part of the pipe end geometry itself.

AI summary
A connecting device for a sealed exchange of fluid between two components is disclosed. The connecting devices comprises a pipe portion with at least two pipe portion ends, wherein an extent of the pipe portion between the pipe portion ends determines a streamline of the fluid, and comprises a sealing element which at least partially surrounds the pipe portion. At least one of the pipe portion ends is configured to form an inflow and/or outflow region that extends over the clear dimension of the at least one pipe portion end.
