Solution Overview

Problem

Conventional air conditioning apparatuses lack flexibility in control and information access, limiting the ability to provide services such as maintenance and function addition due to the integration of hardware and software within the main body.

Innovation Solution

An air conditioning system with a main body device and a remote device connected via a network, featuring a hierarchical software structure with layers for hardware access, control, and function execution, allowing access and control from various locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If hardware and software are integrated in the main body of the air conditioning apparatus, then control and information collection can be performed within the apparatus, but flexibility is limited and access from remote locations is difficult

Engineering Contradiction:
ImproveflexibilityVSAvoidintegration structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the air conditioning system into two separate components: a main body device containing hardware (compressor, heat exchanger, blower fan) and a remote device containing arithmetic processing units and software. This segmentation allows the remote device to access and control the main body via network communication, thereby improving flexibility and enabling remote access without requiring physical presence at the main body location.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If hardware and software are integrated in the main body, then the system structure is simple, but it is less easy to provide services such as maintenance service and function addition

Engineering Contradiction:
ImproveserviceabilityVSAvoidfunction addition capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent extracts the software and arithmetic processing functions from the main body and places them in a separate remote device. This extraction enables independent maintenance of the remote device without affecting the hardware in the main body, and allows easy addition of new functions by updating software in the remote device, thereby improving serviceability and function addition capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If access to the main body is required for control and information collection, then direct control is achieved, but remote access from various locations is limited

Engineering Contradiction:
Improveremote access capabilityVSAvoidaccess information transmission
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent introduces a network communication system as an intermediary between the remote device and the main body device. The network transmits control signals and information between the two components, enabling remote access from various locations without requiring direct physical access to the main body, thereby improving ease of operation for remote control.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An air conditioning system includes a main body device and a remote device. The main body device includes a hardware group and first software that controls the hardware group. The remote device includes an arithmetic processing unit and second software that controls the arithmetic processing unit. The first software includes a hardware access layer, a control layer, and a main body device-side function layer that accepts an order to the main body device and outputs a first instruction to the control layer. The second software includes a remote device-side function layer that accepts an order to the main body device and outputs a second instruction to the control layer via the main body device-side function layer. A function execution program that executes a function of the main body device is in at least one of the main body device-side function layer or the remote device-side function layer.
