Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized database architecture is used to store valuation data, then data access and management is simplified, but security vulnerabilities and single points of failure increase
Solution Approach 1:
The patent divides the centralized database into multiple distributed nodes across different locations. Each node stores a portion of the valuation data, eliminating the single point of failure while maintaining data accessibility through the distributed network architecture.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer that manages data integrity and access control across the distributed database nodes. This intermediary ensures secure data management while maintaining the benefits of distribution.
2Reliability
If all transaction data is stored on blockchain ledger, then transparency and immutability are achieved, but computational overhead and system latency increase
Solution Approach 1:
The patent extracts only the essential transaction data (reward transactions) onto the blockchain ledger, while storing detailed valuation data in traditional databases. This selective extraction maintains transparency for critical operations without overwhelming the blockchain with excessive data.
Solution Approach 2:
The patent applies blockchain technology partially - only for reward transaction recording rather than all data storage. This partial application achieves the necessary transparency and immutability for incentive distribution while avoiding the computational overhead of storing complete valuation datasets on-chain.
3Measurement precision
If GPS verification and physical presence requirements are implemented, then estimate quality and agent verification improve, but system complexity and operational friction increase
Solution Approach 1:
The patent utilizes mobile devices that agents already possess for GPS verification and photo capture. By leveraging the existing multi-functional capabilities of smartphones, the system achieves accurate verification without requiring specialized equipment or complex verification infrastructure.
Solution Approach 2:
The verification process is designed to be agent-initiated and self-completed through the mobile application. Agents autonomously capture photos, verify their location via GPS, and submit estimates without requiring manual verification procedures, reducing operational friction while maintaining accuracy.
4Device complexity
If static algorithmic approaches are used for valuation, then system simplicity is maintained, but ability to incorporate real-time expertise and market conditions deteriorates
Solution Approach 1:
The patent transitions from static valuation algorithms to dynamic models that continuously incorporate real-time market data, recent transaction information, and expert agent inputs. The system adapts to changing market conditions by updating valuation calculations based on the latest available data while maintaining algorithmic processing efficiency.
