Solution Overview
Problem
Manual creation of files for calibration parameters in optical measuring systems is prone to human errors, leading to incorrect calibrations and increased production costs, and lacks automation, especially when dealing with different types and designs of calibration apparatuses.
Innovation Solution
An optical measuring system that uses a calibration apparatus with a predefined spatial arrangement of optical markers to define a code, which encrypts a link to metadata records containing specific calibration parameters, allowing the control unit to automatically access and correct marker positions based on these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual creation of files for calibration parameters is used, then flexibility in handling different calibration apparatuses is maintained, but human errors increase and automation is reduced
Solution Approach 1:
The calibration apparatus automatically identifies itself through the code on its surface. The optical sensor captures the code, the control unit decrypts it to obtain the link to calibration parameters, and automatically retrieves and applies them without human intervention. This self-identification and self-service mechanism eliminates manual file creation while ensuring accurate parameter retrieval.
Solution Approach 2:
The code on the calibration apparatus serves as an intermediary that links the physical calibration apparatus to its digital calibration parameters. This intermediary enables automatic identification and parameter retrieval, bridging the gap between physical hardware and software control without requiring manual intervention.
2Productivity
If manual file creation and assignment is used, then adaptability to different calibration apparatus types is achieved, but time consumption and productivity are reduced
Solution Approach 1:
The code is pre-encoded on the calibration apparatus during manufacturing, containing the link to calibration parameters. This preliminary action eliminates the need for manual file creation and assignment during calibration operations, allowing immediate automatic retrieval and application of parameters, thus significantly improving productivity.
3Adaptability or versatility
If manual file assignment is used, then versatility in handling different calibration apparatuses is maintained, but human errors in assignment increase
Solution Approach 1:
Each calibration apparatus carries its own unique code that automatically identifies it and links to its specific calibration parameters. The system self-services by automatically matching the correct parameters to the correct apparatus, eliminating human assignment errors while maintaining versatility across different apparatus types.
Solution Approach 2:
The code acts as a unique intermediary identifier for each calibration apparatus, ensuring that the correct calibration parameters are automatically retrieved and applied. This intermediary mechanism guarantees reliable assignment while accommodating various calibration apparatus types through their unique codes.
