Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If communication frequency is increased to provide appropriate management service, then management service quality is improved, but communication load and communication charges increase

Engineering Contradiction:

Improvemanagement service qualityVSAvoidcommunication load

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The communication frequency is made dynamic rather than fixed. The communication condition adjusting unit changes the communication frequency based on the operational state of the air conditioner. When the air conditioner is operating normally, communication frequency is reduced. When abnormalities are detected or the system needs updates, communication frequency is increased. This dynamic adjustment resolves the contradiction by providing high communication frequency only when necessary for management service quality while reducing communication load during normal operation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of communication frequency based on the operational state of the air conditioner. The communication condition adjusting unit monitors the air conditioner state and adjusts the communication frequency parameter accordingly. This parameter change approach allows the system to optimize between management service quality and communication load by using high communication frequency only when the air conditioner state requires attention.

Principle #35Parameter changes

2Loss of energy

If communication frequency is decreased to reduce communication load, then communication charges are reduced, but management service quality deteriorates

Engineering Contradiction:

Improvecommunication chargesVSAvoidmanagement service quality

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The communication frequency is dynamically adjusted based on air conditioner operational state. During normal operation, frequency is decreased to reduce communication charges. When abnormalities are detected or management service requires updates, frequency is increased to maintain service quality. This dynamic approach resolves the contradiction by making communication charges low during normal operation while ensuring service quality is maintained when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system adjusts the communication frequency parameter based on monitored air conditioner state. When the air conditioner is operating normally, the parameter is set to a lower frequency to reduce communication charges. When state changes indicate potential issues or when management service requires data updates, the parameter is changed to a higher frequency, ensuring service quality is not compromised.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If communication condition is fixed to simplify system operation, then system complexity is reduced, but adaptability to different equipment states decreases

Engineering Contradiction:

Improvesystem operation simplicityVSAvoidadaptability to equipment state

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The communication condition adjusting unit enables the system to self-adjust communication frequency based on air conditioner operational state without requiring manual intervention. The system automatically monitors its own state and adapts communication conditions accordingly. This self-service approach resolves the contradiction by maintaining operational simplicity (no complex manual configuration needed) while achieving high adaptability to different equipment states through automatic state-based adjustment.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously monitoring air conditioner operational state and using this information to adjust communication frequency. The communication condition adjusting unit receives feedback about equipment state and automatically modifies communication conditions. This feedback mechanism resolves the contradiction by maintaining simple operation (automatic adjustment) while achieving high adaptability (response to actual equipment state).

Inventive Principle:

Principle #23Feedback

AI summary

An equipment management system includes an information processing apparatus obtains equipment information about equipment, and a management apparatus. The management apparatus communicates the equipment information with the information processing apparatus under a predetermined communication condition, and manages the equipment. Either or both of the management apparatus and the information processing apparatus include a candidate communication condition generating unit that generates one or more candidate communication conditions in accordance with one or both of a state of the equipment and a state of an installation space in which the equipment is installed.
