Fluid Joint Component with Cavity-Based Seam Quality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joining components for fluid guidance, such as water heaters, face challenges in reliably and efficiently checking the quality of internal connecting seams, which are inaccessible and often require costly and time-consuming non-destructive testing methods.
Innovation Solution
Incorporating a cavity along the connecting seam with accessible openings in the joining component, allowing for simple leak or overpressure tests to detect quality issues without destroying the component, and using beveled joint surfaces to enhance seam strength and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-destructive testing methods such as computer tomography or ultrasonic testing are used to check inner connecting seams, then the quality and tightness of internal seams can be detected, but the process becomes very time-consuming and cost-intensive
Solution Approach 1:
The inner section of the joining component is segmented to include a cavity that is separated from the channels by the connecting seam. This cavity can be accessed through openings in the outer shell, allowing targeted testing of the connecting seam without requiring complex non-destructive testing of the entire component.
Solution Approach 2:
A cavity is introduced as an intermediary space between the channels and the outer environment. This cavity serves as a mediator that allows fluid to be introduced for testing purposes, enabling the connecting seam to be tested for leaks and quality without direct access to the seam itself and without requiring expensive non-destructive testing methods.
2Reliability
If complex non-destructive testing methods are used to check inner connecting seams, then quality loss can be detected, but the cost increases disproportionately
Solution Approach 1:
The joining component is segmented into an outer shell and an inner section containing the cavity. This segmentation allows the testing function to be integrated into the basic structure without requiring additional expensive testing equipment or complex manufacturing processes.
Solution Approach 2:
The cavity serves multiple functions: it provides space for fluid storage, enables quality testing of the connecting seam, and maintains the structural integrity of the joining component. This multi-functionality eliminates the need for separate testing mechanisms, reducing overall manufacturing costs.
3Reliability
If random testing of joining components is performed, then some quality issues may be detected, but most quality losses in inner connecting seams remain unnoticed
Solution Approach 1:
The cavity and openings are built into the joining component structure during manufacturing, preparing the component for future testing. This preliminary action ensures that every component can be tested systematically rather than requiring random sampling, as the testing infrastructure is already in place.
Solution Approach 2:
The joining component's own structure (the cavity and openings) serves the testing function. The component essentially tests itself through its designed structure, eliminating the need for external complex testing equipment and enabling 100% testing of all components rather than random sampling.

AI summary
The invention relates to a joining component (1) for receiving and/or guiding a fluid, comprising a first partial shell (2) with a first outer surface (10), a first inner surface (12), and a first joining surface (6) provided on the first inner surface (12), and a second partial shell (3) with a second outer surface (13), a second inner surface (14), and a second joining surface (6') provided on the second inner surface (14). The first and second partial shells (2, 3) are connected to each other at the first and second joining surfaces (6, 6') via a connecting seam (5) and form at least two channels (11) for receiving and/or guiding the fluid. The at least two channels (11) are separated from each other in an inner section (8) by the connecting seam (5), and a cavity (15) extending along the connecting seam (5) is provided in the inner section (8).In the first and/or second partial shell (2, 3), at least one opening (7) is provided for checking the quality of the weld (5) between the first joining surface (6) and the first outer surface (10) and/or the second joining surface (6') and the second outer surface (13). The cavity (15) is connected to the at least one opening (7) so that, in the event of a loss of quality in the weld, the fluid escapes at least partially at the first or second outer surface (10, 13).
