Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a centralized digital reward platform is used, then it is easier to manage and process digital rewards, but it becomes vulnerable to cyberattacks, has integrity issues, and faces bottlenecks due to lack of computing resources

Engineering Contradiction:

Improveease of managing and processing digital rewardsVSAvoidsecurity and integrity of digital rewards

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent divides the centralized reward platform into multiple independent nodes distributed across a network. Each node maintains its own copy of the reward ledger and can independently validate transactions, eliminating the single-point-of-failure vulnerability of centralized systems while collectively providing the management functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a decentralized consensus mechanism as an intermediary layer between nodes. This consensus protocol mediates transaction validation and ledger updates without requiring a central authority, enabling nodes to collectively maintain security and integrity while preserving ease of operation through automated consensus processes.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a decentralized system utilizing blockchain technology is implemented, then transaction security and integrity are enhanced, but device complexity increases

Engineering Contradiction:

Improvetransaction security and integrityVSAvoidcomplexity of decentralized system architecture

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs each node to perform multiple functions: storing ledger copies, validating transactions, propagating updates, and participating in consensus. This multi-functionality reduces the need for specialized components and simplifies the overall system architecture while maintaining high security and integrity through distributed operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If a centralized platform is used, then processing speed is faster, but bottlenecks occur due to lack of computing resources

Engineering Contradiction:

Improveprocessing speed of digital rewardsVSAvoidscalability and resource availability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent combines the computing resources of multiple independent nodes into a collective processing capacity. By merging these distributed resources, the system achieves both high processing speed through parallel transaction validation and improved scalability as new nodes can be added to expand total computing power without creating centralized bottlenecks.

Inventive Principle:

Principle #5Merging (Combining)
