Sanitary Installation Part Latching Protuberance Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary installation parts, such as backflow preventers, require a large housing mount with a significant circumferential insertion incline to accommodate the angled spring arms, limiting directional flexibility and making non-destructive removal difficult, especially when inserted against the spring arm angle.
Innovation Solution
The sanitary installation part features latching protuberances that can be elastically deflected into a zero position, allowing optional insertion in or against the flow direction and enabling installation without a latching groove or counter latching element, with rounded or beveled edges for smooth engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring arms are angled outwardly to engage latching grooves, then the installation part can be securely latched in position, but the housing mount requires a large circumferential insertion incline that enlarges dimensions and limits insertion direction
Solution Approach 1:
The patent inverts the conventional latching mechanism by making the housing mount active (with latching protrusions) rather than passive (with grooves). The installation part becomes the passive element with recesses, allowing insertion from any direction while maintaining secure latching through the inverted engagement geometry.
Solution Approach 2:
The housing mount with active latching protrusions and circumferential groove serves multiple functions: it provides secure latching engagement, accepts insertion from any direction (360-degree versatility), and guides the installation part during insertion. This universal design eliminates the need for specific insertion orientations.
2Reliability
If spring arms are fixed at an angle to provide latching, then the installation part can engage with latching grooves, but removal becomes destructive when inserted against the spring arm angle
Solution Approach 1:
The patent introduces dynamic elements through resilient means (springs) that allow the latching protrusions to move between engaged and disengaged states. This dynamic capability enables non-destructive removal by allowing the resilient means to push the protrusions out of engagement, eliminating the need for destructive force.
Solution Approach 2:
The resilient means temporarily store mechanical energy during engagement and release it during disengagement. The latching system can be repeatedly engaged and disengaged without damage, allowing the installation part to be removed and reinstalled multiple times, effectively recovering the component for reuse.
3Reliability
If angled spring arms are used for latching, then secure engagement is achieved, but the housing mount dimensions must be enlarged to accommodate the insertion incline
Solution Approach 1:
By inverting the latching mechanism to use active protrusions on the housing mount rather than passive grooves, the patent eliminates the need for large circumferential insertion inclines. The protrusions can engage with recesses in the installation part from any direction, maintaining secure latching while minimizing housing mount dimensions.
4Reliability
If the installation part is designed with fixed-angle latching elements, then it can engage with matching grooves, but it cannot be inserted into mounts without latching grooves or with different groove configurations
Solution Approach 1:
The housing mount design with active latching protrusions and a circumferential groove creates a universal interface that can engage with installation parts having recesses at various positions. The circumferential groove guides insertion while the protrusions provide latching, allowing compatibility with different mount configurations (with or without grooves, different groove positions) while maintaining reliable engagement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design facilitates flexible and non-destructive assembly and disassembly by allowing insertion with either face and into mounts with or without latching grooves, reducing the need for extensive housing modifications and ensuring simple dismantling.
Implementation Method 1
at least one latching protuberance can be elastically deflected from its zero position into a latching element mount, in which the latching protuberance engages the outer circumference of the installation housing or the installation cage

AI summary
A sanitary installation part (1) which has an installation housing (2) which can be inserted into a housing mount of a gas line or a liquid line is provided and has at least one latching element which projects into a latching position on the outer circumference of the housing and can be moved in a resiliently elastic manner from this latching position to a zero position. The installation part according to the invention provides that the at least one latching element is designed as a latching protuberance (5) which is beveled or rounded along its transverse edges oriented transversely to the insertion direction on both sides, and the at least one latching protuberance (5), in its zero position, can be can be resiliently fitted into the latching element mount, in which the latching protuberance (5) is incorporated in the outer circumference of the installation housing (2).
