Wireless Interior Distributing System for Multi-Region Appliance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart remote control systems for home electrical appliances are limited to controlling devices within a single region or room, requiring multiple remote controls for different groups of appliances and are difficult to reconfigure due to fixed control center locations, restricting one-to-many operation and ease of use.
Innovation Solution
An interior distributing system that includes a remote control and a controller allowing for wireless communication, enabling one-to-many control of home electrical appliances within a defined control area, expandable via repeaters, using radio frequency identification or infrared signals for operation commands, allowing flexible control and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional remote control is used to control home electrical appliances, then the control is limited to a single room or region, but multiple remote controls are required for different groups of appliances in different regions
Solution Approach 1:
The system divides the control function into two parts: a central controller that manages multiple appliance groups and remote controls that only send commands. This segmentation allows one remote to control multiple appliances across different regions through the central controller, eliminating the need for multiple remote controls.
Solution Approach 2:
The central controller acts as an intermediary between the remote control and home electrical appliances. The remote control sends commands to the central controller, which then distributes them to the appropriate appliances in different regions, enabling extended control range without requiring multiple remotes.
2Adaptability or versatility
If a control center is used to control home electrical appliances, then the number of appliances can be easily changed, but the control center location is fixed due to wiring restrictions
Solution Approach 1:
The system replaces the mechanical wiring-based control system with a wireless communication system. The central controller communicates with appliances and remote controls wirelessly, eliminating the restriction of fixed location imposed by physical wiring and allowing the control center to be relocated easily.
3Reliability
If remote controls are paired with specific appliance groups in different regions, then each group can be controlled independently, but managing multiple paired remote controls becomes difficult
Solution Approach 1:
The system merges the control functions for multiple appliance groups into a single central controller. Instead of having separate paired remote controls for each region, one remote control can manage all appliance groups through the central controller, simplifying remote control management while maintaining accurate control of each group.

AI summary
An interior distributing system includes a remote control, a controller, and at least one home electrical appliance. The remote control includes at least one buttons, and the button is used for triggering an corresponding operation command. The controller receives the operation command of the remote control. The home electrical appliance is located within a control area able to receive signals from the controller. While the controller receives the operation command of the remote control, the controller transmits the operation command to the home electrical appliance and the home electrical appliance performs a process task in response to the operation command.
