Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If narrowband communication methods are used, then device complexity is reduced, but security and reliability deteriorate due to vulnerabilities to detection and interception

Engineering Contradiction:

Improvehardware complexityVSAvoidsecurity and reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent changes the fundamental communication parameter from narrowband to wideband/ultra-wideband pulse-based communication. This parameter change enables signals to operate below the noise floor, making them undetectable and uninterceptable, thereby resolving the security and reliability issue without requiring complex additional hardware layers

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces traditional narrowband RF communication mechanics with pulse-based wideband communication mechanics. The substitution involves using short duration pulses with wide spectral content instead of continuous narrowband carriers, fundamentally changing how communication occurs at the physical layer to achieve security and reliability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If wide-band or ultra-wide-band pulse-based communication methods are used, then security and reliability are improved, but device complexity increases due to software-defined radio requirements

Engineering Contradiction:

Improvesecurity and reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service through automatic blockchain authentication and encryption processes. The system automatically performs security handshakes, key exchanges, and authentication verification without manual intervention, reducing the operational complexity burden despite the advanced communication hardware

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The software-defined radio platform serves multiple functions: wideband/ultra-wideband pulse communication, blockchain authentication, encryption/decryption, and protocol management. By consolidating these functions into a single multi-functional platform, the patent reduces overall device complexity compared to having separate dedicated systems for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If Blockchain authentication and encryption are integrated, then security is improved, but processing time increases due to authentication handshakes

Engineering Contradiction:

Improvecyber securityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary action by pre-establishing blockchain authentication credentials and encryption keys before communication begins. The authentication handshake and key exchange occur in advance, allowing subsequent communications to proceed with reduced processing time while maintaining high security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous encrypted communication sessions once authenticated. The blockchain authentication establishes a persistent secure session that maintains encryption and authentication states throughout the communication duration, eliminating the need for repeated authentication handshakes and reducing overall processing time

Inventive Principle:

Principle #20Continuity of useful action

4Difficulty of detecting and measuring

If pulse-based wide-band communication is used, then detectability is reduced, but bandwidth requirements increase

Engineering Contradiction:

Improveprobability of detectionVSAvoidbandwidth

Core Design Contradiction:

Difficulty of detecting and measuringVSQuantity of substance

Solution Approach 1:

The patent uses periodic short duration pulses instead of continuous wideband signals. By transmitting information through repeated short pulses rather than continuous wideband carriers, the system achieves wideband communication benefits (low detectability, high security) while reducing overall bandwidth consumption through duty cycle management

Inventive Principle:

Principle #19Periodic action
