Calibration Certificate Reproduction via Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic instruments with limited non-volatile storage capacity face challenges in storing and reproducing calibration certificates, as traditional methods require large storage space for even compressed documents, making it difficult to maintain availability for quality processes and audits.
Innovation Solution
The method involves separating calibration certificate data into calibration-specific and document-descriptive subsets, storing the descriptive metadata within the instrument and the static content externally, allowing for reconstruction of the certificate using an application on a separate computing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If calibration certificate is stored as compressed image or PDF in electronic instrument, then certificate availability is improved, but storage capacity is exceeded
Solution Approach 1:
The calibration certificate is segmented into two parts: calibration-specific data (stored in instrument memory) and document-descriptive data (stored externally). This segmentation allows the instrument to store only essential calibration parameters rather than the entire certificate document, resolving the contradiction between certificate availability and storage capacity constraints.
Solution Approach 2:
The document-descriptive portion of the calibration certificate is extracted from the instrument and stored externally in a computing device. Only the critical calibration-specific data remains in the instrument's limited memory, enabling certificate reproduction without exceeding storage capacity while maintaining full certificate availability when needed.
2Quantity of substance
If traditional paper certificate method is used, then storage space requirement is reduced, but certificate availability and accessibility deteriorate
Solution Approach 1:
Instead of storing physical paper certificates or large document images, the system creates a digital reproduction of the calibration certificate by combining calibration-specific data from the instrument with document-descriptive data from external storage. This digital copying approach minimizes storage space requirements while improving accessibility through electronic retrieval and display.
3Adaptability or versatility
If full calibration certificate data is stored in instrument, then certificate reproduction capability is improved, but device complexity increases
Solution Approach 1:
The certificate data is segmented into calibration-specific and document-descriptive components, with each stored in appropriate locations. This segmentation simplifies data management by storing only essential calibration parameters in the instrument while maintaining full certificate reproduction capability through external data retrieval and combination.

AI summary
A method and a system for reproducing a calibration certificate of an electronic instrument having at least one electronic storage means, the method involving separating the calibration certificate data into a first subset of data, which is calibration specific, and a second subset of data, which is document descriptive; defining a set of meta data about the second subset of data; storing the first subset of data and the set of meta data in the instrument's electronic storage means; storing the second subset of data in a computing device separated from the electronic instrument; and reproducing the calibration certificate by uploading the first subset of data and the set of meta data to the computing device and reconstructing the calibration certificate from the uploaded first subset of data set of meta data and the second subset of data.
