Solution Overview
Problem
Existing optical measuring apparatuses face challenges in managing calibration data effectively when the sensor head and controller are separated, as they lack electronic components for storing calibration data, leading to complicated data management and potential errors in measurement values.
Innovation Solution
An optical measuring apparatus with a controller, sensor head, and an adapter that includes a memory for storing calibration data, allowing for easy management and connection of the sensor head and controller, even with extension cables, and enabling recognition of cable length and contamination detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If calibration data is stored separately from the sensor head, then the sensor head can remain simple without electronic components, but the management of calibration data becomes complicated
Solution Approach 1:
The patent introduces an adapter as an intermediary component that contains the memory for storing calibration data. This adapter connects between the sensor head and controller, allowing calibration data to be stored in a centralized location that is easily accessible to both components. The adapter serves as a mediator that resolves the conflict between keeping the sensor head simple and enabling easy calibration data management.
2Adaptability or versatility
If the sensor head and controller are separated by a cable, then the sensor head can be positioned flexibly, but calibration data cannot be retained without electronic components in the head
Solution Approach 1:
The adapter acts as an intermediary that bridges the separated sensor head and controller while providing a reliable storage location for calibration data. By placing the memory in the adapter rather than in the sensor head, the system maintains the flexibility of having a cable-connected, positionable sensor head while ensuring reliable calibration data retention through the adapter's electronic storage capability.
3Device complexity
If no memory is provided in the adapter, then the adapter remains simple, but calibration data cannot be stored for correcting measurement values
Solution Approach 1:
The patent segments the system into distinct functional components: the sensor head for optical measurement, the adapter for data storage and management, and the controller for processing. By segmenting the memory function into the adapter rather than integrating it into the sensor head or controller, the system achieves measurement precision through proper calibration data storage while keeping each component's complexity manageable and focused on its primary function.
