Solution Overview

Problem

Existing switching arrangements require a rocker switch for magnetic field detection, which is not feasible with toggle switches due to space constraints and lack of a rear side for magnet attachment, limiting their application and increasing installation complexity.

Innovation Solution

A toggle switch design with a pivotable rocker arm equipped with a magnet, such as a magnetic sleeve or adhesive film, allows magnetic field detection without the need for additional wiring, enhancing signal-to-noise ratio and enabling toggle switch integration with minimal installation effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rocker switch is used for magnetic field detection, then magnetic field detection is reliable, but the application is limited and installation complexity increases

Engineering Contradiction:
Improvemagnetic field detection reliabilityVSAvoidswitching device type compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by enabling the magnetic field detection system to work with multiple types of switching devices (rocker switches, toggle switches, push buttons) through a common evaluation unit that identifies different switch types based on magnetic field change patterns. This allows one functional module to serve multiple switching device types without requiring type-specific hardware.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses parameter changes by detecting different magnetic field change patterns (parameters) caused by different switching device types. The evaluation unit identifies the switching device type by analyzing characteristics of the magnetic field changes, such as the magnitude, duration, or waveform of the field changes, allowing differentiation between rocker switches, toggle switches, and push buttons.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a magnet is attached to a rocker switch, then magnetic field detection works well, but toggle switches cannot be used due to space constraints

Engineering Contradiction:
Improvemagnetic field detection reliabilityVSAvoidswitching device area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent applies local quality by placing the magnet at specific locations on the switching device actuator where it produces the most effective magnetic field changes for detection. The evaluation unit is configured to detect magnetic field changes from magnets positioned on various types of switching devices, including compact toggle switches, by optimizing the detection parameters for each device type's specific geometry and magnet location.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If additional wiring is used for functional module connection, then installation effort increases, but magnetic field detection becomes unnecessary

Engineering Contradiction:
Improveinstallation effortVSAvoidwiring complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies mechanics substitution by replacing the mechanical/electrical wiring system with a magnetic field-based communication system. Instead of using physical cables to connect the switching device to the functional module, the system uses magnetic field changes generated by a magnet on the switching device actuator to transmit actuation signals wirelessly to the functional module's sensor.

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

4Ease of manufacture

If magnetic field detection is used without switch type identification, then installation is simple, but control functionality is limited

Engineering Contradiction:

Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies self-service by enabling the functional module to automatically identify the switching device type through the evaluation unit's analysis of magnetic field change patterns. The system performs self-configuration without requiring manual setup or programming, automatically adapting its control functionality based on the detected switch type, whether rocker switch, toggle switch, or push button.

Inventive Principle:
Principle #25Self-service
