Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complete and thorough system testing is conducted during installation, then reliability of power system operation is improved, but loss of time and productivity deteriorate due to testing taking weeks or months

Engineering Contradiction:
Improvepower system operation reliabilityVSAvoidtesting duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent creates a virtual copy of the power system in an emulation environment that replicates the physical system's behavior, allowing comprehensive testing of the virtual model instead of the actual physical system. This copying approach enables thorough testing of all possible configurations and failure modes without requiring extended periods of physical system testing.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The emulation environment serves as an intermediary between the design phase and physical deployment. By introducing this virtual testing layer, the system allows complete validation of power system configurations, control logic, and failure responses before actual equipment is installed and tested, significantly reducing on-site testing time while maintaining reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If complete and thorough system testing is conducted during installation, then reliability of power system operation is improved, but device complexity increases due to extensive testing requirements

Engineering Contradiction:
Improvepower system operation reliabilityVSAvoidtesting system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical and physical testing apparatus with a software-based emulation system. Instead of requiring complex physical test equipment, switchgear, and cabling arrangements, the solution uses virtual models and software simulations to replicate system behavior, thereby reducing physical device complexity while enabling comprehensive testing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

By creating virtual copies of power system components and their interconnections, the patent eliminates the need for complex physical test setups. The virtual model captures all system behaviors, control logic, and failure modes, allowing thorough testing without the complexity of arranging extensive physical testing infrastructure.

Inventive Principle:
Principle #26Copying

3Measurement precision

If actual power system operation is used for testing, then testing accuracy is improved, but harmful factors increase due to hydrocarbon emissions from carbon-based fuel generators

Engineering Contradiction:
Improvetesting accuracyVSAvoidhydrocarbon emissions
Core Design Contradiction:
Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The patent creates accurate virtual replicas of power system components, including engine-driven generators, that replicate operational characteristics, control responses, and failure modes. This virtual copying enables testing under all possible operating conditions without actually running carbon-based fuel generators, thereby maintaining testing accuracy while eliminating hydrocarbon emissions.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent converts the limitation of not being able to test actual operating conditions into a benefit by using high-fidelity virtual modeling. The emulation environment accurately reproduces the behavior of carbon-based fuel generators under various conditions, allowing complete testing without the harmful emissions that would result from actual operation during the testing phase.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Measurement precision

If actual equipment is operated during testing, then testing realism is improved, but loss of substance increases due to fuel consumption

Engineering Contradiction:
Improvetesting realismVSAvoidfuel consumption
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

The patent creates virtual models of engine-driven generators that accurately simulate fuel consumption characteristics, operational responses, and performance under various loads. By testing these virtual copies instead of actual generators, the system maintains complete testing realism regarding operational behavior while eliminating actual fuel consumption during the testing phase.

Inventive Principle:
Principle #26Copying
