Battery-Free RF Pairing Control for Home Automation Receivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home automation devices with low-energy nominal uses face power depletion during pairing processes, as existing methods like those described in document FR1658952A can deplete their power supply, preventing normal functioning.
Innovation Solution
A control device that utilizes the energy of an incident signal to send configuration signals without relying on an internal power source, such as a battery, by converting radio frequency signals into electrical current to power the device's logic processing unit and transmitter/receiver, using a converter and energy smoothing unit to manage energy levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple control devices are connected in a master-slave configuration for coordinated control, then control coordination and collaborative operation are improved, but communication failures and system reliability deteriorate due to wireless link vulnerabilities
Solution Approach 1:
The master control device acts as an intermediary that receives control instructions from the control terminal and processes them before distributing to slave control devices. This intermediary structure enables coordinated control while providing a centralized point for error detection and correction, thereby maintaining communication reliability in the wireless master-slave configuration
2Ease of operation
If control instructions are transmitted wirelessly between devices, then system flexibility and ease of operation are improved, but communication errors and reliability deteriorate due to wireless link instability
Solution Approach 1:
The master control device receives feedback information from slave control devices regarding the execution status of control instructions. This feedback mechanism enables real-time monitoring of wireless communication effectiveness and allows for error detection and correction, maintaining reliability while preserving wireless flexibility
3Manufacturing precision
If control instructions are processed and distributed through a master control device, then control precision and coordination are improved, but processing delays and response time deteriorate
Solution Approach 1:
The master control device pre-processes control instructions and prepares them for distribution to slave devices. By performing preliminary processing and organization of control commands before they are needed for execution, the system achieves precise coordinated control while minimizing real-time processing delays during actual operation
