Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wireless communication is used to replace wired communication between air-conditioning units, then the cost in communication lines and engineering wiring is reduced, but communication reliability deteriorates due to signal interference from multiple refrigerant systems sharing the same network

Engineering Contradiction:
Improvecost in communication lines and engineering wiringVSAvoidcommunication reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent segments the wireless communication network by introducing network identification (ID) that divides all air-conditioning units into multiple isolated groups. Each refrigerant system is assigned a unique network ID, creating virtual segments that prevent signal interference between different systems while maintaining wireless communication benefits. This resolves the contradiction by enabling both cost reduction and reliability improvement through network segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces network identification (ID) as an intermediary element that mediates communication between air-conditioning units. The network ID acts as a mediator that routes signals appropriately and prevents interference from other systems. This intermediary mechanism enables reliable wireless communication by filtering and directing signals without requiring physical wiring separation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If multiple refrigerant systems use wireless communication in the same network, then installation complexity is reduced, but communication chaos occurs between different refrigerant systems

Engineering Contradiction:
Improveinstallation complexityVSAvoidcommunication order
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies segmentation by dividing the wireless network into multiple isolated groups using network identification. Each refrigerant system operates in its own virtual segment identified by a unique ID, preventing communication chaos while maintaining simple wireless installation. This allows multiple systems to coexist without interference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by assigning different network identification characteristics to different refrigerant systems. Each system has its own unique network ID that distinguishes it from others, creating locally optimized communication channels within the global wireless network. This enables clear identification and routing of signals for each system.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If wireless communication networks are shared by all air-conditioning units, then the requirement of engineering wiring is reduced, but signal received by an outdoor unit may not be from the intended indoor unit

Engineering Contradiction:
Improverequirement of engineering wiringVSAvoidsignal source identification accuracy
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent introduces network identification (ID) as an intermediary that enables accurate signal source identification in wireless communication. The network ID acts as a mediator that tags and tracks signals, allowing outdoor units to identify which indoor unit transmitted each signal. This resolves the identification accuracy problem while maintaining wireless communication advantages.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the communication parameter by introducing network identification as an additional dimension for signal differentiation. Instead of relying solely on physical connection identification, the system uses network ID parameters to identify signal sources and routing. This parameter addition enables accurate identification in wireless environments without requiring wiring.

Inventive Principle:
Principle #35Parameter changes
