Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a centralized database is used for data management, then ease of operation is improved, but reliability deteriorates due to vulnerability to hacking and data leakage

Engineering Contradiction:
Improveease of operationVSAvoidreliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts the centralized database management function from the system and replaces it with distributed storage across multiple user devices. Each user device stores its own data locally without relying on a central server, thereby eliminating the single point of failure while maintaining operational simplicity through automated local management.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The centralized database is segmented into multiple distributed storage units across different user devices. Data is divided and stored across the network rather than concentrated in one location, which improves reliability by preventing single-point failures while maintaining ease of access through networked retrieval.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a centralized management system is used, then ease of operation is improved, but loss of information increases due to potential hacking and data leakage

Engineering Contradiction:
Improveease of operationVSAvoidloss of information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent extracts data from centralized storage and places it in distributed local storage across user devices. This extraction eliminates the vulnerability of centralized data repositories to hacking while maintaining operational simplicity through automated local data management and retrieval mechanisms.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements prior cushioning by encrypting data before storage and establishing secure communication protocols in advance. This preparatory security measures cushion against potential hacking attempts and data leakage, protecting information while maintaining ease of legitimate operations.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If one-time passwords are used for authentication, then reliability is improved, but device complexity increases

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service authentication where user devices automatically generate and manage their own cryptographic keys and authentication credentials without requiring external verification. This self-service mechanism maintains high reliability through secure local authentication while reducing device complexity by eliminating the need for complex centralized authentication infrastructure.

Inventive Principle:
Principle #25Self-service

AI summary

Disclosed herein is a content wallet device. The content wallet device to which a storage device storing a content is connected may include: a communication unit for communication between the content wallet device and a user terminal device; an encryption unit generating encryption data including a user ID and a password for authentication between the content wallet device and the user terminal device; a switch unit controlling an electrical connection between the storage device and the communication unit; and a reset unit initializing the generated password when the electrical connection between the storage device and the communication unit is released by the switch unit. Accordingly, when a user sells a content, the user and a purchaser may directly sell and purchase the content, respectively, without transferring authority to a central management system, and by generating a new password whenever the user authenticates ownership of the content, a third party hacking may be prevented to prevent illegal leakage of the content.
