Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional operation modes (rapid and comfortable modes) are used, then the air conditioner can provide basic cooling functions, but the operation cannot dynamically reflect changes in external temperature, humidity, and occupancy, leading to suboptimal performance

Engineering Contradiction:
Improveadaptability to environmental changesVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms by collecting operational data from multiple indoor units and using learning algorithms to dynamically adjust operation modes. The system continuously monitors environmental parameters and occupancy changes, then feeds this information back to optimize cooling performance in real-time, resolving the contradiction between adaptability and system complexity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The air conditioner system performs self-optimization through automated learning processes that analyze operational data and adjust modes without requiring manual intervention. The system serves itself by automatically adapting to environmental changes and occupancy patterns, improving versatility while maintaining manageable complexity through autonomous decision-making.

Inventive Principle:
Principle #25Self-service

2Speed

If the air conditioner operates in rapid mode with maximum cooling capacity, then the cooling speed is fast, but the energy consumption is high

Engineering Contradiction:
Improvecooling speedVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by transitioning from static operation modes to dynamic mode switching based on real-time learning outcomes. The system dynamically adjusts between rapid and comfortable modes according to learned patterns of environmental changes and occupancy, optimizing the balance between cooling speed and energy consumption rather than relying on fixed modes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters dynamically by adjusting cooling capacity, fan speeds, and mode selection based on learned environmental conditions. Rather than maintaining constant maximum capacity, the system modifies parameters in response to predicted occupancy and environmental changes, reducing energy consumption while maintaining effective cooling speed when needed.

Inventive Principle:
Principle #35Parameter changes

3Use of energy by moving object

If the air conditioner operates in comfortable mode with reduced cooling output, then the energy consumption is lower, but the system cannot respond quickly to sudden environmental changes or occupancy increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidresponse reliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent implements preliminary action by using learning algorithms to predict future occupancy patterns and environmental changes before they occur. The system proactively adjusts operation modes in advance based on learned patterns, ensuring reliable response to upcoming changes while maintaining energy efficiency during stable periods. This predictive capability allows the system to switch to rapid mode before occupancy increases or environmental conditions deteriorate.

Inventive Principle:
Principle #10Preliminary action

4Productivity

If operation information from multiple indoor units is collected and analyzed, then the overall system performance can be optimized, but the data processing complexity and communication overhead increase

Engineering Contradiction:
Improvesystem performanceVSAvoiddata processing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges data from multiple indoor units into a centralized learning system that analyzes aggregated information to optimize overall performance. By combining operational data across multiple units and applying learning algorithms centrally, the system achieves improved productivity through coordinated optimization while managing data processing complexity through unified analysis rather than distributed processing.

Inventive Principle:
Principle #5Merging (Combining)
