Innovation Solution

An air-conditioner control interface device that includes an interface controller, external-device-information input/output unit, air-conditioner-information input/output unit, and an external-recording-medium input/output unit, allowing for customizable interface control information storage and interpretation, enabling flexible information transmission and reception without the need for multiple output units or switches.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple external-device output units and switches are provided to increase information output capability, then the adaptability and versatility are improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improveinformation output capabilityVSAvoidcontrol board size
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal output unit that can output various types of information (operation information, control information, diagnostic information, etc.) to multiple types of external devices (remote controllers, personal computers, card keys, coin timers, centralized controllers) through a single interface. This multi-functional design eliminates the need for multiple dedicated output units and switches, thereby reducing device complexity while maintaining high adaptability and versatility.

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

2Adaptability or versatility

If multiple external-device output units and switches are provided to increase information output capability, then the adaptability and versatility are improved, but the manufacturing cost increases

Engineering Contradiction:
Improveinformation output capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By designing a single universal output unit that can handle multiple information types and external device connections, the patent reduces the number of components that need to be manufactured and assembled. This eliminates the need for multiple switches and jumpers, thereby reducing manufacturing cost while maintaining the capability to support diverse external devices and information types.

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

3Ease of manufacture

If input/output contents are fixed to suppress board size and manufacturing cost, then the ease of manufacture is improved, but the adaptability and versatility deteriorate

Engineering Contradiction:
Improveboard size and manufacturing costVSAvoidcustomization capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic configurability to the output unit, allowing the information output contents to be changed based on the connected external device type and user needs. The system can dynamically select and output appropriate information types (operation information, control information, diagnostic information, etc.) without requiring physical hardware changes, thereby maintaining small board size and low manufacturing cost while achieving high adaptability and customization capability.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If software or hardware changes are made to the control board whenever different information is input or output, then the adaptability and versatility are improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improveinformation input/output flexibilityVSAvoidcontrol board configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic information selection mechanism that allows the control board to flexibly configure information input/output based on the connected external device without requiring physical hardware changes. The system can dynamically adjust which information types are output (operation information, control information, diagnostic information, etc.) through software control, thereby achieving high adaptability while maintaining simple and consistent hardware configuration.

Inventive Principle:
Principle #15Dynamics
