Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data entry on pre-printed report sheets is used, then calibration certificates can be generated, but the process is slow and prone to human error
Solution Approach 1:
The patent replaces manual mechanical data entry processes with electronic data capture and transmission systems. Portable field operable communication devices capture calibration data electronically and transmit it wirelessly to remote information management devices, eliminating the need for manual transcription on pre-printed report sheets and reducing both time and errors.
Solution Approach 2:
The patent creates electronic copies of calibration data that can be transmitted and stored digitally. Instead of physically copying data from instruments to paper forms, the system creates digital replicas that can be automatically processed, validated, and used to generate certificates, significantly improving speed and accuracy.
2Reliability
If manual comparison and certificate preparation is performed in the office, then calibration certificates can be issued, but the process is slow and may fail to alert for remedial actions
Solution Approach 1:
The patent implements automated feedback loops where the remote information management device receives calibration data, automatically compares it against compliance criteria, and generates appropriate responses. The system provides real-time alerts and notifications to stakeholders, ensuring timely awareness of compliance status and necessary remedial actions without manual intervention.
Solution Approach 2:
The system enables self-service calibration certification by automatically performing data validation, compliance checking, and certificate generation. The remote information management device autonomously processes calibration data and produces certificates or error reports without requiring manual office-based preparation, significantly improving productivity while maintaining compliance.
3Reliability
If paper-based calibration records are used, then calibration data can be stored, but human error may result in failure to provide alerts for remedial action
Solution Approach 1:
The patent replaces manual paper-based record keeping and error detection with automated electronic systems. The remote information management device automatically analyzes calibration data, detects errors through programmed criteria, and generates alerts, eliminating human oversight failures and significantly reducing the time to detect and communicate calibration issues.
