Solution Overview

Problem

Existing actuator and switching devices for emergency off switches suffer from wear and tear or soiling, leading to reduced functional reliability and safety, as visual markings become illegible over time.

Innovation Solution

Integration of an RFID element with storage capabilities, using NFC protocols, on the actuator or switching device components for traceability, authentication, and data storage, eliminating the need for visible markings and enhancing security against counterfeiting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If visual markings (engravings, printing, stickers) are used on actuator and switching device, then component identification is enabled, but the markings become illegible due to wear and tear or soiling during use

Engineering Contradiction:
Improvelegibility of markingsVSAvoidfunctional safety
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent replaces visual markings (mechanical/optical identification method) with an RFID element (electromagnetic field-based identification system). The RFID element stores information about the command or signaling device and can be read without physical contact, eliminating wear and soiling issues associated with surface markings while maintaining component identification capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If RFID element is integrated on actuator component, then traceability and authentication are improved, but device complexity increases

Engineering Contradiction:
ImprovetraceabilityVSAvoidstructure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The RFID element is merged with an existing component of the actuator (such as the button or housing), combining identification functionality with structural elements already present in the device. This integration approach adds traceability capability while minimizing the increase in overall device complexity by reusing existing components rather than adding separate identification modules.

Inventive Principle:
Principle #5Merging (Combining)

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

The RFID element ensures improved traceability and authentication, enabling early identification and replacement of defective components, simplifying logistics and warehousing, and maintaining operational safety without visible markings that can wear off.

Implementation Method 1

An RFID element is provided on a component of the actuator, having storage means in which information about the command or signaling device and/or individual parts of the command or signaling device is stored so that it can be read out.
