Solution Overview
Problem
In systems with multiple terminals, remote control conflicts can arise due to simultaneous signal transmission, leading to inappropriate control of appliances.
Innovation Solution
A remote control system that includes a notification management device to determine the appropriate terminal for remote control based on beacon signal strength, using appliance identification information to ensure the notification signal is sent to the nearest user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a remote control system transmits signals to all terminals, then all terminals can control the appliance, but remote control conflicts occur due to simultaneous signal transmission
Solution Approach 1:
The notification management device acts as an intermediary between terminals and the appliance. It receives beacon information from the appliance, determines which terminal should receive notifications based on proximity or other criteria, and selectively transmits activation information to that terminal. This mediator approach resolves the contradiction by enabling multi-terminal capability while preventing conflicting simultaneous control through centralized coordination.
2Ease of operation
If notification signals are sent to all terminals, then all users are notified, but mistaken control of similar appliances may occur
Solution Approach 1:
The system applies local quality by providing different notification treatments to different terminals based on their specific relationship to the appliance. The notification management device determines which terminal receives the activation notification based on local conditions such as proximity (beacon signal strength) or pre-configured associations. This ensures notifications are sent to the appropriate terminal for each specific appliance, preventing mistaken control while maintaining comprehensive notification coverage.
3Adaptability or versatility
If the system registers multiple terminals with the appliance, then multiple users can control the appliance, but determining the correct terminal becomes complex
Solution Approach 1:
The notification management device implements self-service by automatically determining which terminal should receive activation notifications without requiring complex manual configuration or user intervention. The system uses beacon signal strength or pre-registered terminal information to automatically identify the appropriate terminal. This self-determination mechanism reduces management complexity while maintaining multi-terminal support capability.

AI summary
A remote control system (1) includes an appliance (30), a first terminal (10), a second terminal (20), and a notification management device (50) that stores appliance identification information in association with first terminal information and second terminal information. The appliance (30) includes a beacon transmitter (32) that transmits a beacon including first appliance information. The first terminal (10) includes a beacon receiver (12), a remote controller (11), and a first information transmitter (13) that transmits a beacon received signal strength, the first terminal information, and the first appliance information to the notification management device (50). The second terminal (20) includes a beacon receiver (22), a remote controller (21), and a second information transmitter (23) that transmits a beacon received signal strength, the second terminal information, and the first appliance information to the notification management device (50). The notification management device (50) transmits a notification signal including remote controller activation information to only one of the first terminal (10) and the second terminal (20) that has a higher received signal strength.
