Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used to store document hashes, then document authenticity and unchangeability are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The system separates document verification into distinct modules: hash generation module, blockchain storage module, and verification module. Each module handles a specific task, making the overall complex blockchain system manageable and easier to implement while maintaining document authenticity guarantees
Solution Approach 2:
The patent introduces an intermediary verification system that mediates between documents and blockchain storage. This intermediary layer simplifies the interaction complexity by providing standardized interfaces for hash deposition and verification, reducing the burden on users while maintaining reliability
2Device complexity
If manual verification of document authenticity is performed, then system complexity is reduced, but verification time and labor costs increase
Solution Approach 1:
The system implements automated self-service verification where the verification algorithm automatically compares document hashes against blockchain records without requiring manual intervention. This eliminates verification delays and labor costs while keeping the system relatively simple through rule-based automation
Solution Approach 2:
The patent replaces manual mechanical verification processes with automated electronic hash comparison algorithms. This substitution eliminates time-consuming manual checks while maintaining system simplicity through straightforward computational operations
3Measurement precision
If comprehensive document metadata is stored, then document identification accuracy is improved, but data storage requirements and processing overhead increase
Solution Approach 1:
The system extracts only the essential identifying metadata (GPS coordinates, timestamps, device identifiers) from complete document information and stores only these critical elements in the blockchain. This extraction approach maintains identification accuracy for verification purposes while significantly reducing data storage requirements and processing overhead

AI summary
The system for automatic management and depositing of documents' (images') hash in the block-chain technology comprises of at least one device for documents' recording, and/or for the conversion of documents into digital photography (1), at least one device through which communication and encoding are performed (2), at least one device through which user authentication is performed (3), at least one device on which the block-chain base is located (4) and at least one device on which the hash base is located (5). The device (1) comprises at least a digital camera, a communication system, an image processing system and the GPS, and it may additionally include an adequate software application. The communication system is a virtual VPN specifically dedicated to the device (1), and communication among the devices within the system is carried out through the Internet and it is encoded. In the device (5), the hash base is divided per tables into blocks that can be fast searched by searching the tables linked to the blocks A−1, A and A+1 first, and the hash table determines the actual address of the document in the block-chain through the hash value.
