Switch Module for Building Lighting Control via Door Sensor

Solution Overview

Problem

Existing building control systems face challenges in usability and cost-effectiveness, particularly in private buildings, where controlling multiple installations such as lighting, heating, and blinds is cumbersome and expensive, with high wiring efforts and limited automation capabilities.

Innovation Solution

A switch module connected to a door sensor that detects the door status and adjusts lighting and other building services accordingly, using a dedicated interface for door sensors and allowing for wireless communication, enabling easy configuration and reduced wiring needs, with the option for local operation even without a central unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If individual switches or control panels are used to control each installation separately, then control precision is improved, but device complexity and wiring effort increase

Engineering Contradiction:

Improvecontrol precisionVSAvoidwiring effort

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple control functions into a single switch module that can control multiple installations (lighting, heating, blinds) through one interface. The switch module integrates multiple control channels that can independently control different installations, eliminating the need for separate switches for each device and reducing wiring complexity while maintaining precise control capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The switch module is designed with universal functionality to control various types of installations through a single device. It includes multiple control channels that can be assigned to different installations, and the module can adapt to control lighting, heating, blinds, and other building services through parameter configuration rather than requiring hardware changes

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If individual switches are used for each installation, then control precision is improved, but ease of operation deteriorates due to inconvenience and difficulty in automation

Engineering Contradiction:

Improvecontrol precisionVSAvoidoperation convenience

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent combines multiple control functions into a single switch module that can control multiple installations (lighting, heating, blinds) through one interface. The switch module integrates multiple control channels that can independently control different installations, eliminating the need for separate switches for each device and reducing wiring complexity while maintaining precise control capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system incorporates feedback mechanisms where the control unit receives status information from installations and automatically adjusts control signals. This enables automated control scenarios where the system responds to changing conditions without requiring manual intervention for each individual control action

Inventive Principle:

Principle #23Feedback

3Ease of operation

If complex building technology installations are implemented to improve user comfort, then ease of operation is improved, but cost-effectiveness deteriorates

Engineering Contradiction:

Improveuser comfortVSAvoidcost-effectiveness

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The switch module is designed with universal functionality to control various types of installations through a single device. It includes multiple control channels that can be assigned to different installations, and the module can adapt to control lighting, heating, blinds, and other building services through parameter configuration rather than requiring hardware changes, thereby reducing overall system cost

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables control of different installations by changing software parameters and configuration settings rather than requiring different hardware components. The switch module can be reconfigured through coded descriptions of parameters to control different types of installations, providing versatility without increasing hardware costs

Inventive Principle:

Principle #35Parameter changes

AI summary

The invention relates to a keypad comprising a plurality of input keys and a controller which responds to keys being pressed, said controller being designed to identify whether input keys were pressed shortly one after the other in a certain order, whether input keys pressed in said way pertain to a predefined group and to change, in response to said identification, a future response to a key being pressed.
