Solution Overview

Problem

Existing air conditioner installation check systems do not ensure that operators perform appropriate confirmation of installation work before a trial run, leading to potential incorrect installations if the operator misses or neglects work environment instructions.

Innovation Solution

An installation check system that includes a remote controller and control circuit, allowing operators to confirm installation compliance with work instructions through a display and input process, and only enabling a trial run if the installation is verified as correct.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If work environment instruction is displayed for the operator, then the operator can access installation guidance, but the operator may still neglect or fail to follow the instructions

Engineering Contradiction:
Improveaccess to work environment instructionVSAvoidconfirmation of installation correctness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system requires the operator to perform check operations confirming installation correctness before the air conditioner is allowed to execute a trail run. This preliminary verification step ensures that installation instructions are not only accessed but actually followed and confirmed before operation begins.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control circuit receives check results from the operator and provides feedback by determining whether to permit the trail run based on whether the installation is confirmed correct. This feedback mechanism ensures that the system only operates when proper installation verification has been completed.

Inventive Principle:
Principle #23Feedback

2Reliability

If the operator is required to perform check operations, then installation correctness can be verified, but the operation process becomes more complex

Engineering Contradiction:
Improveverification of installation correctnessVSAvoidcheck operation process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The remote controller, already a universal device for operating the air conditioner, is also used for performing installation check operations and inputting check results. This multi-functionality approach avoids adding separate dedicated verification devices, thereby minimizing additional complexity while ensuring reliable installation verification.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If the trail run is allowed without proper check, then the system operates efficiently, but incorrect installation may cause harmful effects

Engineering Contradiction:
Improvetrail run executionVSAvoidincorrect installation consequences
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The control circuit performs preliminary determination of installation correctness before allowing the trail run to execute. By checking and verifying installation status in advance, the system prevents harmful effects that could result from incorrect installation, such as improper refrigerant flow or electrical issues.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

This application discloses an installation check system (100, 100B) used for checking installation of an air conditioner before a start of a trail run of the air conditioner. The installation check system (100, 100B) includes a display portion (210) for displaying work instruction information about the installation, an input means (220) configured to be operated for entering a check result based on the work instruction information, a determination portion (340) configured to determine whether the start of the trail run is allowed based on the check result, and a signal generator (350) which generates a drive signal to execute the trail run. The signal generator generates the drive signal under condition of the determination portion allowing the start of the trail run.
