Solution Overview

Problem

Existing air conditioning installation check systems do not effectively verify whether the air conditioner is correctly installed, relying on manual check marks without assurance of proper installation.

Innovation Solution

A system comprising a use side device of an air conditioner, a terminal, and a management server, where the terminal transmits identification information of the use side device to the management server, which compares this information with stored data to determine if the installation is appropriate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual check marks are used for installation verification, then the operation is simple and quick, but the reliability of installation verification is insufficient

Engineering Contradiction:
Improvesimplicity of installation checkVSAvoidaccuracy of installation verification
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables automatic self-verification of installation by having the terminal device automatically transmit its identification information to the management server, which then automatically compares it with the pre-stored correct information. This eliminates the need for manual checking while ensuring accurate verification of whether the air conditioner is installed at the correct location.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The management server provides automatic feedback by comparing the terminal's identification information with the stored correct information and determining whether the installation is appropriate. This feedback mechanism ensures reliable verification without requiring manual intervention, resolving the contradiction between operational simplicity and verification reliability.

Inventive Principle:
Principle #23Feedback

2Reliability

If identification information transmission and comparison system is implemented, then the reliability of installation verification is improved, but the device complexity increases

Engineering Contradiction:
Improveaccuracy of installation verificationVSAvoidcomplexity of verification system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The management server acts as an intermediary that handles the complex tasks of storing correct identification information, receiving transmission data, performing comparisons, and determining installation appropriateness. This intermediary approach allows the terminal device to remain relatively simple while achieving reliable verification through the server's processing capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The manual mechanical checking process is replaced with an automated information transmission and comparison system using communication protocols and data processing. This substitution increases reliability by eliminating human error while the distributed architecture (terminal + server) keeps individual device complexity manageable.

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

AI summary

A system includes a use side device of an air conditioner; a terminal; and a management server, wherein the terminal transmits first information for identifying the use side device installed in a predetermined property to the management server, and wherein the management server stores second information as information on a use side device to be installed in the predetermined property, and based on the first information and the second information received from the terminal, the management server determines whether the use side device installed in the predetermined property matches the use side device to be installed in the predetermined property.
