Solution Overview

Problem

Existing air conditioning systems lack the ability to determine and actively adopt the most energy-efficient operation patterns, leading to suboptimal energy saving opportunities.

Innovation Solution

An energy saving support apparatus connected to multiple air conditioning systems via a network, which receives data on installation environments and power consumption, groups systems by similarity, selects the most energy-efficient systems, and transmits performance benchmarks to others in the same group, providing information for energy savings and detecting potential abnormalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If air conditioning systems operate independently with stored operation patterns, then each system maintains operational autonomy, but energy saving opportunities are lost due to inability to share best practices

Engineering Contradiction:
Improveenergy consumptionVSAvoidenergy saving information
Core Design Contradiction:
Loss of energyVSLoss of information

Solution Approach 1:

The energy saving support apparatus collects operation data from multiple air conditioning systems, analyzes energy consumption patterns, and feeds back optimal operation patterns to systems that need improvement. This closed-loop feedback mechanism enables continuous energy optimization across the network by sharing proven energy-saving experiences from high-performing systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The support apparatus serves multiple functions: it acts as a data collection center, analysis engine, and distribution hub for energy-saving information. By creating a universal platform that handles all these functions, the system enables energy optimization across diverse air conditioning installations without requiring individual systems to develop their own optimization capabilities.

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

2Ease of operation

If operation patterns are stored and reused, then operational simplicity is maintained, but adaptability to find more efficient patterns is reduced

Engineering Contradiction:
Improveoperation pattern managementVSAvoidenergy optimization capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

Air conditioning systems automatically receive and apply optimized operation patterns from the support apparatus without requiring manual intervention. The systems self-adjust their operation based on received recommendations, maintaining ease of operation while adapting to more efficient patterns through automated updates.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The support apparatus pre-analyzes operation data from multiple systems to identify optimal patterns before distributing them to individual systems. This preliminary analysis ensures that when patterns are distributed, they are already optimized and ready for immediate implementation, combining analytical adaptability with operational simplicity.

Inventive Principle:
Principle #10Preliminary action

3Loss of energy

If each system determines its own operation patterns independently, then system autonomy is preserved, but energy efficiency is suboptimal due to lack of comparative analysis

Engineering Contradiction:
Improvepower consumptionVSAvoidnetwork coordination system
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The energy analysis and optimization function is extracted from individual air conditioning systems and centralized in the support apparatus. This separation allows individual systems to remain simple while the centralized system handles the complex task of comparative analysis and optimization pattern generation across the entire network.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The energy saving support apparatus acts as an intermediary between multiple air conditioning systems, collecting data from all systems, performing comparative analysis, and distributing optimized patterns. This intermediary role enables energy efficiency improvements without requiring direct complex interactions between individual systems.

Inventive Principle:
Principle #24Intermediary (Mediator)
