Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional cryptographic key generation methods are used, then encryption security can be maintained, but computational resources and time requirements increase significantly

Engineering Contradiction:
Improveencryption securityVSAvoidcomputational resources
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces traditional algorithmic key generation with a physical blending process. Materials are blended according to defined parameters (ratios, sequences, methods) to create a physical mixture whose properties generate the encryption key. This substitutes computational algorithms with a physical process that can be reproduced deterministically without requiring extensive computational resources.

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

Solution Approach 2:

The patent transforms key generation from a computational parameter space to a physical parameter space. By controlling blending parameters (material types, quantities, mixing sequences, environmental conditions), the system generates encryption keys through measurable physical properties of the blend (color, density, viscosity) rather than through computational complexity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If encryption keys are transmitted over insecure channels, then key distribution is enabled, but security is compromised due to potential interception and modification

Engineering Contradiction:
Improvekey distribution capabilityVSAvoidkey security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent enables each communicating party to independently generate the same encryption key by performing the blending process locally using the same materials and parameters. This eliminates the need to transmit the key itself over insecure channels, as each party self-generates the key through the reproducible physical process rather than receiving it through potentially vulnerable transmission channels.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The physical blend acts as an intermediary carrier of the encryption key. Instead of transmitting the key directly through vulnerable communication channels, the key is embedded in the physical properties of a material blend that can be independently reproduced by authorized parties without direct key transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If brute-force approaches are used for decryption, then unauthorized access becomes possible with increased computational power, but legitimate decryption remains efficient with proper keys

Engineering Contradiction:
Improveunauthorized accessVSAvoiddecryption time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent replaces algorithmic encryption with encryption based on physical blend properties. The encryption key is derived from measurable physical characteristics of a material blend (optical, mechanical, chemical properties) that are difficult to predict without performing the actual blending process, thereby resisting brute-force computational attacks.

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

Solution Approach 2:

The patent uses composite material blends as the foundation for key generation. By combining multiple materials in specific proportions and sequences, the resulting blend has complex physical properties that serve as the encryption key. This composite approach creates key material that is computationally difficult to guess or brute-force without knowing the exact blending parameters.

Inventive Principle:
Principle #40Composite materials
