Calibration Tool with Machine-Readable Label for Optical Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high variability in production conditions of calibration tools for optical diagnostic systems leads to each tool being uniquely assigned to a specific system, resulting in additional expenses, complex maintenance, and potential inaccuracies if the wrong tool is used or if the assigned tool is lost.
Innovation Solution
A calibration tool equipped with a machine-readable label containing setpoint values and a pupil that mimics the human eye, allowing for semi-automatic calibration of multiple optical diagnostic systems by scanning the label and comparing actual values with stored setpoint values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a calibration tool is manufactured with high precision, then measurement accuracy is improved, but device complexity and production variability increase
Solution Approach 1:
The patent uses a machine-readable label containing digital copy of calibration data instead of relying solely on physical precision of the calibration tool. The label stores setpoint values that represent the ideal calibration parameters, allowing the system to compare actual measurements against these reference values and compensate for manufacturing variations.
Solution Approach 2:
The patent changes the calibration approach from relying on physical dimensional precision to using variable parameter storage and retrieval. The machine-readable label allows calibration parameters to be digitally defined and updated, separating the calibration data from the physical tool geometry and enabling flexible parameter management.
2Measurement precision
If each calibration tool is uniquely assigned to a specific diagnostic system, then calibration accuracy is improved, but productivity and ease of operation worsen
Solution Approach 1:
The machine-readable label contains universal calibration data that can be used across multiple diagnostic systems. The label stores setpoint values that are system-agnostic, allowing a single calibration tool to serve multiple systems without compromising calibration accuracy, thereby improving productivity and reducing the number of tools needed.
3Measurement precision
If each calibration tool is uniquely assigned to a specific diagnostic system, then measurement precision is improved, but loss of time increases due to maintenance and repair complexity
Solution Approach 1:
The machine-readable label can be easily replaced or updated on calibration tools, allowing rapid recovery of calibration functionality. If a label becomes damaged or outdated, it can be quickly replaced with a new label containing the necessary calibration data, minimizing downtime and maintenance complexity compared to replacing entire calibration tools or systems.
