Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional security tokens like SIM cards and embedded chips are used for authentication, then basic communication security is provided, but the system becomes vulnerable to hacking techniques such as computer viruses, communication network attacks, and wiretapping

Engineering Contradiction:

Improvecommunication securityVSAvoidvulnerability to hacking

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a dedicated encryption module as an intermediary component between the communication application and the data transmission layer. This module handles all cryptographic operations independently, protecting communication data from vulnerabilities in conventional SIM card and chip-based security systems while maintaining secure authentication mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces conventional mechanical security tokens (SIM cards, embedded chips) with a software-based encryption module that implements advanced cryptographic algorithms. This substitution eliminates the physical vulnerability points in traditional security hardware while providing robust protection against computer viruses, network attacks, and wiretapping.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If encryption/decryption functionality is added to protect communication data, then security against unauthorized access is improved, but the device complexity increases

Engineering Contradiction:

Improvedata protectionVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the encryption module with the existing mobile device architecture, integrating cryptographic functionality into the phone's processing system. This consolidation approach provides strong data protection while avoiding the complexity of separate standalone encryption devices, as the encryption module shares resources and operates within the existing device framework.

Inventive Principle:

Principle #5Merging (Combining)
