Solution Overview

Problem

The challenge lies in easily checking the network connection status of an air-conditioner communication system without visually accessing the wireless LAN adapter, particularly after its installation, especially when it is installed in hard-to-reach locations such as behind a ceiling.

Innovation Solution

The system employs a terminal device with display and operation functions to access and display connection information from the wireless LAN adapter, allowing users to confirm and manage network connections without direct interaction with the adapter, using a user interface that shows the status of connections between the air conditioner, wireless LAN adapter, router, and server.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the wireless LAN adapter is installed in hard-to-reach locations (e.g., behind ceiling), then the air conditioner can be easily incorporated into the local area network, but it becomes difficult to visually check the adapter and perform pairing operation

Engineering Contradiction:
Improveease of network incorporationVSAvoidease of pairing operation
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent introduces a terminal device (smartphone, tablet, or PC) as an intermediary between the user and the wireless LAN adapter. The terminal device displays pairing information and connection status, allowing users to perform pairing operations and check connection status without directly interacting with the physically inaccessible adapter. This mediator resolves the contradiction by enabling ease of operation through remote interface while maintaining the adapter's optimal installation location for network incorporation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the wireless LAN adapter is installed in hard-to-reach locations, then the air conditioner can be easily incorporated into the local area network, but it becomes difficult to check the network connection status

Engineering Contradiction:
Improveease of network incorporationVSAvoiddifficulty of checking connection status
Core Design Contradiction:
Ease of manufactureVSDifficulty of detecting and measuring

Solution Approach 1:

The terminal device serves as an intermediary that retrieves and displays connection status information from the wireless LAN adapter. The adapter communicates connection status to the terminal device, which then presents this information through a user-friendly interface. This allows easy detection and measurement of network connection status without requiring physical access to the adapter installed in hard-to-reach locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/visual checking method (directly observing the adapter's LED indicators or physically accessing the device) with an electronic information display system. The connection status is transmitted electronically to the terminal device and displayed on its screen, substituting the need for direct visual inspection of the physical adapter with remote electronic monitoring.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
