Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If counterfeit devices are created using reverse engineering and cloned mask sets, then functional mimicry of original devices is achieved, but unique electromagnetic signatures are lost making detection difficult

Engineering Contradiction:
Improvefunctional reliabilityVSAvoidsignature differentiation precision
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent transforms the detection approach by changing measurement parameters from functional electrical testing to electromagnetic spectrum analysis. By measuring reflection and transmission spectra across multiple frequencies and ports, the system captures unique electromagnetic fingerprints that reveal subtle manufacturing variations invisible to functional testing, thereby resolving the contradiction between functional mimicry and detectability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent adds a new dimension to device characterization by moving from single-point electrical measurements to multi-frequency, multi-port electromagnetic spectrum analysis. This dimensional expansion creates a comprehensive signature space where counterfeit devices cannot hide their non-native functionality, overcoming the limitation of functional equivalence

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If non-native functionality is inserted into cloned devices, then security risks increase, but detection capability remains insufficient with conventional methods

Engineering Contradiction:
Improvesecurity riskVSAvoiddetection difficulty
Core Design Contradiction:
Object-affected harmful factorsVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces electromagnetic spectrum analysis as an intermediary detection mechanism that indirectly reveals non-native functionality. Rather than directly probing for malicious code or altered circuitry, the system measures electromagnetic reflections and transmissions that are influenced by subtle structural differences, providing a safe and effective detection pathway

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies preliminary anti-action by establishing electromagnetic signature baselines for authentic devices before deployment. These pre-characterized signatures serve as reference patterns that enable rapid detection of deviations caused by non-native functionality, preventing security threats from going undetected

Inventive Principle:
Principle #9Preliminary anti-action

3Ease of operation

If conventional measurement techniques are used, then device functionality can be tested, but unique electromagnetic signatures cannot be captured

Engineering Contradiction:
Improvetesting simplicityVSAvoidelectromagnetic signature information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent creates a universal measurement system that simultaneously performs functional testing and electromagnetic signature capture. The multi-port vector network analyzer executes standardized S-parameter measurements that serve both quality assurance purposes and unique fingerprinting, eliminating the need for separate testing procedures while preserving all relevant information

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