Solution Overview
Problem
Existing methods for calibrating measuring instruments are time-consuming, costly, and lack trustworthiness when performed by operators, and existing technologies do not leverage distributed ledger technology (DLT) for a digitized calibration process.
Innovation Solution
A method utilizing DLT to enable secure, automated, and efficient on-site calibration by integrating non-falsifiable digital records and encrypted communication between the measuring instrument, working standards, and a testing authority, allowing operators to perform recalibration flexibly and transparently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual calibration by operators is performed, then flexibility and accessibility are improved, but trustworthiness and reliability deteriorate
Solution Approach 1:
A digital intermediary system comprising a mobile device, DLT network, and verification authority acts as a mediator between the operator and the calibration process. The mobile device captures calibration data, the DLT network securely transmits and stores it, and the verification authority validates the results. This intermediary chain maintains operator flexibility while ensuring trustworthiness through cryptographic verification and immutable recording.
2Measurement precision
If traditional calibration processes are used, then measurement accuracy is maintained, but time consumption and cost increase
Solution Approach 1:
The patent replaces the mechanical/physical calibration process with a digital system. Instead of physically transporting devices to laboratories and using paper-based documentation, the system uses digital capture of calibration data via mobile device cameras, cryptographic hashing, DLT for secure transmission and storage, and automated verification. This substitution maintains measurement precision through verified calibration constants while dramatically reducing time and cost.
3Productivity
If digitalization of calibration process is implemented, then efficiency and transparency are improved, but system complexity increases
Solution Approach 1:
The patent employs universal, multi-functional components that handle multiple tasks. The mobile device serves as camera, scanner, communication terminal, and verification interface. The DLT network provides distributed storage, secure transmission, timestamping, and verification capabilities simultaneously. The verification authority validates both calibration constants and device identity. This multi-functionality reduces overall system complexity despite the digital transformation.
