Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a substituting power source such as a generator is used to compensate for lost phases, then continuous power supply is maintained, but system complexity and cost increase

Engineering Contradiction:

Improvecontinuous power supplyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system uses the existing functioning phases to compensate for the lost phases through automatic phase compensation circuitry. The compensation system utilizes the available phases to generate the missing phase signals, allowing the system to self-compensate without external substituting power sources. This eliminates the need for additional generators or complex backup systems while maintaining continuous three-phase power supply.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The phase compensation system enables the existing power source to perform multiple functions: it simultaneously provides normal three-phase power when all phases are functioning and automatically compensates for lost phases when malfunctions occur. The same circuitry serves both normal operation and fault compensation, eliminating the need for separate substituting power sources.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If substituting power sources are implemented, then power continuity is ensured, but installation and operational cost increase

Engineering Contradiction:

Solution Approach 1:

The compensation system uses the existing power infrastructure and phases to generate compensation signals, eliminating the need for additional generators or expensive backup power sources. The system automatically detects phase losses and uses the remaining functioning phases to compensate, reducing both installation and operational costs while ensuring power continuity.

Inventive Principle:

Principle #25Self-service

Solution Approach 1:

The phase compensation circuitry acts as an intermediary between the existing power source and the load. When phase losses occur, the compensation circuitry processes the available phase signals and generates the missing phase signals, mediating the power transmission to ensure continuous three-phase supply without requiring alternative power providers.

Inventive Principle:
