Wi-Fi RF Converting Device Centralized Appliance Control

Solution Overview

Problem

The inconvenience of controlling multiple electric appliances remotely, particularly those far away, due to the proliferation of remote controls and the lack of integration with Wi-Fi networks, leads to inefficiencies in operation and increased time searching for the correct remote control.

Innovation Solution

A Wi-Fi/RF converting device that converts Wi-Fi signals into RF signals to control multiple electric appliances simultaneously, utilizing a Wi-Fi transceiver, multiplexing converting module, and radio frequency transceiver, with optional wireless extension devices for expanded control capabilities, allowing for centralized control via a smartphone or similar device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple remote controls are provided for different electric appliances, then each appliance can be controlled specifically, but the time to find the correct remote control increases and operation becomes more complex

Engineering Contradiction:

Improvecontrol capabilityVSAvoidtime to find remote control

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent combines multiple remote control functions into a single Wi-Fi enabled controller that can communicate with multiple electric appliances through a mobile device. Instead of having separate remote controls for each appliance, the system merges all control functions into one interface, eliminating the time loss of searching for different remote controls while maintaining the ability to control multiple appliances specifically.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a universal control system where a single mobile device can control various types of electric appliances (AC, TV, refrigerator, etc.) through Wi-Fi communication. The system provides multi-functionality by enabling one controller to perform multiple control tasks across different appliances, replacing the need for multiple specialized remote controls.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple remote controls are provided for different electric appliances, then each appliance can be controlled specifically, but the operation complexity increases

Engineering Contradiction:

Improvecontrol capabilityVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a mobile device as an intermediary between the user and multiple electric appliances. Instead of requiring direct interaction with multiple different remote controls, the mobile device serves as a universal intermediary that communicates with all appliances through Wi-Fi, simplifying the user interface while maintaining specific control capabilities for each appliance type.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/electronic system of multiple physical remote controls with a wireless communication system based on Wi-Fi and mobile devices. This substitution eliminates the physical complexity of managing multiple remote control devices while maintaining the ability to control specific appliances through software interfaces on the mobile device.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If traditional RF remote controls are used, then appliances can be controlled wirelessly, but integration with Wi-Fi networks is lacking and future scalability is limited

Engineering Contradiction:

Improvewireless controlVSAvoidnetwork integration

Core Design Contradiction:

AI summary

A Wi-Fi/radio frequency (RF) converting device includes a Wi-Fi transceiver, a multiplexing converting module, an RF transceiver, and an RF extension device. The Wi-Fi transceiver receives a Wi-Fi control signal from a control signal generator, wherein the Wi-Fi control signal contains at least one command. The multiplexing converting module receives the Wi-Fi control signal from the Wi-Fi transceiver, and converts the Wi-Fi control signal into a first wireless control signal or a second wireless control signal. The RF transceiver is electrically connected to the multiplexing converting module, and is connected to at least one electric appliance through RF signals. The RF transceiver receives the first wireless control signal from the multiplexing converting module, and transmits the RF control signal to the electric appliance. The RF extension device transmits the second wireless control signal, which corresponds to at least one another electric appliance, to the at least one another electric appliance.
