Diaphragm Valve RFID Layout for Reliable Identification Readout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diaphragm valves face challenges in easily and reliably reading out identification data, such as RFID chips, due to their placement on valves, which can lead to incorrect readings and accessibility issues during mounting and operation.
Innovation Solution
The diaphragm valve design includes a first identification means on a laterally protruding tab and additional identification means on the flange and/or base, with read-out surfaces arranged perpendicularly to each other, ensuring easy and safe reading by preventing misalignment and increasing distance between identification means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple identification means are positioned far away from each other on different parts of the valve, then the risk of reading the wrong identification means is reduced, but the accessibility for reading out data becomes more difficult
Solution Approach 1:
The patent applies dimensionality change by arranging read-out surfaces of identification means in different spatial orientations (perpendicular to each other). The first identification means has its read-out surface facing upward, while the second identification means has its read-out surface facing sideways. This allows a reading device to access both identification means from a single approach direction, resolving the contradiction between spatial separation for reliability and accessibility for ease of operation.
2Measurement precision
If the read-out device is not held exactly above the read-out surface, then another identification means may be read out inadvertently, but positioning precisely is difficult during operation
Solution Approach 1:
The patent applies asymmetry by orienting read-out surfaces of different identification means in perpendicular directions rather than identical directions. The first read-out surface faces upward while the second faces sideways at a 90-degree angle. This asymmetric arrangement creates distinct spatial signatures for each identification means, allowing the reading device to clearly distinguish which identification means is being read based on the device's orientation, thereby maintaining high read-out precision while simplifying operational ease.

AI summary
A diaphragm valve having a movable diaphragm (20) configured as a closure element has a valve housing (6) and an actuator (8), the diaphragm (20) being clamped between a flange (18) of the valve housing and a base (10) of the actuator (8) and being provided with a first identification means (32) in which data which are adapted to be read out wirelessly are stored. A further identification means (50, 56) is also fastened to the flange (18) and/or the base (10). The read-out surfaces of the further identification means (50, 56) are substantially at right angles to the read-out surface of the identification means (32) on the diaphragm (20).
