Bus Coupler Button Attachment with Dual RF and TP Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retrofitting KNX radio products into existing KNX TP systems in building automation is costly and time-consuming due to the need for a separate RF/TP media coupler, which requires additional installation efforts and preparatory measures.
Innovation Solution
A button attachment with a dual radio interface that supports both wireless and wired signal transmission, allowing for the integration of RF and TP communication within the button attachment itself, eliminating the need for a separate media coupler by using existing bus couplers and minimizing installation effort through self-startup capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate RF/TP media coupler is installed to enable communication between KNX-RF and KNX-TP devices, then communication compatibility is improved, but device complexity and installation effort increase
Solution Approach 1:
The patent combines the RF interface and TP bus coupler into a single integrated device. The button attachment includes both a radio interface for RF communication and a signal interface for TP communication, merging the functions of what would traditionally require separate RF/TP media coupler and button attachment components into one unified device that can communicate with both KNX-RF and KNX-TP devices directly
Solution Approach 2:
The button attachment is designed with multi-functionality to serve dual communication protocols. It can both generate wired telegrams for TP transmission and receive/send wireless telegrams via RF interface, making it a universal device that bridges both KNX-RF and KNX-TP networks without requiring separate specialized components
2Adaptability or versatility
If a separate RF/TP media coupler is installed to enable communication between KNX-RF and KNX-TP devices, then communication compatibility is improved, but installation time and cost increase
Solution Approach 1:
The patent combines the RF interface and TP bus coupler into a single integrated device. The button attachment includes both a radio interface for RF communication and a signal interface for TP communication, merging the functions of what would traditionally require separate RF/TP media coupler and button attachment components into one unified device that can communicate with both KNX-RF and KNX-TP devices directly
Solution Approach 2:
The button attachment is pre-configured with both RF and TP communication capabilities during manufacturing. The device comes ready-to-use with integrated firmware that handles both communication protocols, eliminating the need for complex on-site configuration and reducing installation time to simply mounting the single integrated device
