Domestic Appliance Acknowledgment via Relay Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current domestic appliance control systems using radiofrequency signals face reliability issues in acknowledging command receipt due to temporary interruptions or poor communication quality, leading to incomplete or inaccurate acknowledgment information for management equipment.
Innovation Solution
A method that involves updating acknowledgment information at the domestic appliance level, broadcasting it, and then updating the management equipment's stored information, ensuring reliable communication of receipt status through a structured frame of time slots dedicated to each appliance for acknowledgment signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acknowledgment signals are transmitted directly from each domestic appliance to management equipment, then the system can obtain acknowledgment information, but temporary interruptions or poor communication quality may cause signals to be lost and acknowledgment information to be incomplete
Solution Approach 1:
The patent introduces intermediate domestic appliances as mediators in the acknowledgment transmission process. When a domestic appliance cannot directly transmit its acknowledgment signal to management equipment due to communication issues, other domestic appliances receive and forward these acknowledgment signals, ensuring that acknowledgment information reaches the management equipment reliably even in the presence of communication interruptions
Solution Approach 2:
The patent implements preliminary actions by having domestic appliances continuously monitor and collect acknowledgment signals from other appliances before management equipment needs to retrieve the complete acknowledgment information. This ensures that acknowledgment data is prepared and available in advance, reducing the impact of temporary communication failures
2Reliability
If the system uses a structured frame of time slots dedicated to each appliance for broadcasting acknowledgment signals, then transmission reliability is enhanced, but the device complexity increases
Solution Approach 1:
The patent segments the communication process into structured time slots within frames, with each domestic appliance assigned specific time slots for broadcasting acknowledgment signals. This segmentation organizes the complex multi-appliance communication into manageable, time-divided segments, making the system more reliable while keeping the complexity controlled through systematic allocation
Solution Approach 2:
The patent implements periodic action through repeating frames of time slots, where each frame contains dedicated time slots for each domestic appliance to broadcast acknowledgment signals. This periodic structure creates a predictable, rhythmic communication pattern that enhances reliability through regular transmission opportunities while simplifying management through repetition

AI summary
The method involves receiving a signal carrying acquittal information by a domestic apparatus i.e. roller blind, where the acquittal information comprises inter alia acknowledgement information and acknowledgement information. The acknowledgement information is updated by the domestic apparatus. The signal is diffused by the domestic apparatus. The signal is received by a management equipment. The acknowledgement information is updated by the management equipment. Independent claims are also included for the following: (1) an equipment for managing a domestic apparatus control system by radio frequency signals, comprising a receiving unit (2) a domestic apparatus controlled by a management equipment of a control system by exchanging radio frequency signals, comprising a diffusing unit.
