Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wired connection is used for communication between air conditioner outdoor units and indoor units, then communication reliability is improved, but installation complexity increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidinstallation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical wired connection system with a wireless communication system. The remote controller establishes wireless connections with both the indoor unit and outdoor unit, eliminating the need for physical wiring between these components. This substitution maintains communication functionality while significantly reducing installation complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The remote controller serves as an intermediary device that mediates communication between the indoor unit and outdoor unit. Instead of direct wired connection between units, the remote controller receives information from the indoor unit and transmits control signals to the outdoor unit wirelessly, simplifying the overall system architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If wired connection is used for air conditioner networking, then communication stability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvecommunication stabilityVSAvoidinstallation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The wired mechanical connection system is replaced with wireless communication. The remote controller communicates with the indoor and outdoor units using wireless signals, eliminating the need for installing and connecting physical wires, thereby greatly improving installation convenience while maintaining communication stability through protocol-level error handling.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If wired connection is used between air conditioner units, then communication reliability is improved, but device cost increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoiddevice cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive wired connection infrastructure with more cost-effective wireless communication technology. The remote controller uses wireless protocols to communicate with the air conditioner units, eliminating the need for specialized wiring materials and installation labor, thereby reducing overall device cost while maintaining adequate communication reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
