Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If test data is stored locally in each laboratory using proprietary software, then data availability for local access is improved, but data traceability and integrity across different laboratories deteriorate
Solution Approach 1:
The patent introduces a terminal as an intermediary component between the test machine and the test database. This terminal handles data encoding, compression, and transmission, acting as a mediator that standardizes data exchange between different laboratory systems and the centralized database, thereby ensuring traceability without requiring complex direct integrations between all systems.
Solution Approach 2:
The patent replaces manual or proprietary data transfer mechanisms with an automated electronic transmission system. Data is automatically encoded, compressed, and transmitted via network to the centralized database, eliminating the need for manual data handling and proprietary software interfaces at each laboratory, thus improving traceability while managing complexity through standardization.
2Reliability
If data is transferred between laboratories using conventional methods, then transfer speed is improved, but data integrity and authenticity deteriorate
Solution Approach 1:
The patent applies preliminary actions by encoding and compressing data before transmission. The data is prepared in advance with encoding (e.g., MD5) and compression applied, so that when transmission occurs, it is already optimized for integrity and efficiency. This preliminary processing ensures data integrity is maintained throughout transfer while minimizing additional processing time during actual transmission.
Solution Approach 2:
The patent changes data parameters through encoding and compression transformations. By applying encoding algorithms and compression ratios, the data is transformed into a format that maintains integrity during transmission while reducing size. This parameter transformation allows faster transmission without compromising data authenticity or requiring excessive processing time.
3Adaptability or versatility
If test data is made accessible to multiple laboratories, then data sharing and collaboration are improved, but data security and confidentiality deteriorate
Solution Approach 1:
The patent segments data access control by implementing authentication mechanisms that differentiate between various user roles and laboratories. Each laboratory and user has specific access permissions defined, allowing data to be shared across multiple laboratories while maintaining security through segmented access control. This enables collaborative versatility while mitigating security risks through granular permission management.
4Loss of information
If data is stored in a centralized database, then data availability and traceability are improved, but system vulnerability to attacks deteriorates
Solution Approach 1:
The patent implements data redundancy through copying mechanisms. Critical data and its integrity verification information are stored in multiple copies within the centralized database system. This ensures that even if one copy is compromised or lost, the data remains available and traceable, preventing information loss while distributing the impact of potential security incidents across multiple copies rather than creating a single point of failure.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures data availability, integrity, and confidentiality by preventing post-data modification, identifying data contributors, and securely transferring data across laboratories, enhancing end-to-end monitoring and traceability.
Implementation Method 1
generation of a unique digital signature associated with said set of test data, said signature making it possible to identify said set of test data in a definitive manner; the generation of the signature of the test data consists in applying a hash function to said test data
Implementation Method 2
writing and timestamping in the blockchain of said unique digital signature so as to store proof of the date and content of said data set; the terminal itself connected to a database formed of a chain of blocks called blockchain
