Diaphragm Valve Assembly With External Diaphragm Type Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diaphragm valves in existing technologies lack a reliable method to quickly and accurately identify the type and materials of diaphragms during replacement, especially in difficult-to-access installations, which can lead to time delays and potential malfunctions if an unsuitable diaphragm is installed.
Innovation Solution
A diaphragm assembly with a tab featuring a through-opening for a marking element that is visible from multiple sides, allowing identification of the diaphragm type through color or shape differences, and optionally incorporating an electronic data storage element and visual display for enhanced identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a diaphragm has an integrally formed tab for identification, then the diaphragm type can be identified visually, but the identification is still insufficient for quick and reliable determination in difficult-to-access installations
Solution Approach 1:
The patent applies color coding to marking elements (e.g., colored tabs, colored marking elements inserted through the tab) to indicate different diaphragm types, materials, or specifications. This allows for immediate visual identification without requiring close inspection or disassembly, directly resolving the contradiction by enabling both accurate identification and rapid replacement.
Solution Approach 2:
The patent introduces marking elements (such as colored tabs, pins, or markers) as intermediary indicators that provide information about the diaphragm type without requiring direct observation of the diaphragm itself. These marking elements serve as mediators that convey identification information from a distance, enabling quick identification in difficult-to-access installations.
2Device complexity
If the diaphragm is built into the diaphragm valve, then the valve structure is compact, but the diaphragm type cannot be seen from the outside for maintenance purposes
Solution Approach 1:
The patent segments the identification function from the diaphragm itself by introducing separate marking elements (such as colored tabs, pins, or markers) that are distinct from the functional diaphragm components. This segmentation allows the diaphragm to remain compact and built-in while the marking elements provide external visibility for identification purposes.
Solution Approach 2:
The marking elements serve as intermediaries that bridge the gap between the hidden diaphragm and the external observer. These elements are positioned externally or at accessible locations while conveying information about the internal diaphragm type, resolving the contradiction between compact structure and visibility.
3Measurement precision
If materials used for diaphragm layers are visually distinguishable, then diaphragm type can be identified, but this requires close inspection and is not suitable for difficult-to-access installations
Solution Approach 1:
The patent uses color-coded marking elements to represent different diaphragm materials or types. Instead of relying on direct visual inspection of the diaphragm materials themselves, the color coding provides an easily distinguishable external indicator that can be observed from a distance, even in difficult-to-access installations.
Solution Approach 2:
The patent creates a visual copy or representation of the diaphragm type information through marking elements. The marking elements (such as colored tabs or markers) serve as external representations that convey the same identification information as the actual diaphragm materials would, but in a form that is easily observable from a distance.

AI summary
A diaphragm assembly for a diaphragm valve is described, which has a diaphragm which includes a functional portion adapted to cooperate with further components of the diaphragm valve and to separate opposite chambers. The diaphragm further includes a tab projecting laterally from the functional portion and having a through-opening provided therein. A marking element is fastened in the through-opening. In addition, a diaphragm valve having such a diaphragm assembly is presented.
