Air Conditioner Wireless Unit Matching for Stable Networking

Solution Overview

Problem

Wired communication between air conditioner outdoor and indoor units is difficult to install and maintain, requiring physical connections that damage structures and hinder communication efficiency.

Innovation Solution

A remote controller facilitates wireless communication by matching indoor and outdoor units based on acquired information, acting as an intermediate equipment to establish and maintain connections, ensuring seamless synchronization and fault detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wired connection is used for communication between air conditioner outdoor unit and indoor unit, then communication stability is improved, but installation complexity and structural damage increase

Engineering Contradiction:

Improvecommunication stabilityVSAvoidinstallation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical wired connection system with a wireless communication system. The outdoor unit and indoor unit communicate through wireless signals (WiFi, Bluetooth, or other wireless protocols) instead of physical cables, eliminating the need for wall drilling and cable installation while maintaining communication functionality. This substitution resolves the contradiction by removing the structural damage requirement while preserving communication stability through reliable wireless protocols.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless communication module as an intermediary between the outdoor unit and indoor unit. This module handles the wireless signal transmission and reception, acting as a mediator that enables communication without direct physical connection. The intermediary approach allows stable communication to be achieved through protocol-level reliability mechanisms rather than physical connection stability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If wired connection is used for communication between air conditioner outdoor unit and indoor unit, then communication reliability is improved, but installation time and cost increase

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical wired connection system with a wireless communication system. The outdoor unit and indoor unit communicate through wireless signals (WiFi, Bluetooth, or other wireless protocols) instead of physical cables, eliminating the need for wall drilling and cable installation while maintaining communication functionality. This substitution resolves the contradiction by removing the structural damage requirement while preserving communication stability through reliable wireless protocols.

Inventive Principle:
