Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If inductance coils are added to measure individual equipment power consumption, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvepower consumption measurement precisionVSAvoidcontroller structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the total power consumption measurement into individual equipment measurements by adding separate inductance coils for each piece of equipment. Each coil independently measures the current drawn by its associated equipment, allowing the controller to report and analyze power consumption at the individual equipment level rather than only as a aggregate system total.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inductance coils serve as intermediary sensing elements that indirectly measure the power consumption of individual equipment without requiring direct electrical connection to each device. The coils detect magnetic fields generated by equipment current draw and convert them into measurable signals for the controller.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If individual equipment power consumption is monitored, then energy management capability is improved, but information processing requirements increase

Engineering Contradiction:
Improveenergy management capabilityVSAvoiddata processing load
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system implements feedback by continuously monitoring individual equipment power consumption through inductance coils and providing this data back to the controller. The controller can then use this feedback information to identify inefficient equipment, adjust operating parameters, or alert users to abnormal power consumption patterns, enabling proactive energy management.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables self-service energy management by automatically collecting, processing, and presenting power consumption data for individual equipment. This eliminates the need for manual meter reading or external monitoring devices, as the controller autonomously gathers and analyzes the data to provide actionable energy management insights.

Inventive Principle:
Principle #25Self-service
