Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calibration is performed, then calibration accuracy can be ensured, but user time and operational complexity increase
Solution Approach 1:
The calibration data is pre-encoded into a physical pattern on the calibration storage device before use. This preliminary encoding of calibration information allows the device to automatically retrieve and apply calibration parameters without requiring manual calibration operations at the time of use, thus reducing calibration time while maintaining accuracy.
Solution Approach 2:
The system performs self-calibration by automatically reading the encoded pattern from the calibration storage device and applying the calibration data without user intervention. The device calibrates itself by processing the pre-encoded information, eliminating the need for manual calibration steps while ensuring consistent accuracy.
2Reliability
If frequent calibration is performed, then device accuracy is maintained, but user convenience decreases
Solution Approach 1:
The device automatically performs calibration by reading the encoded pattern from the calibration storage device without requiring user intervention. This self-service calibration mechanism maintains device accuracy through frequent calibration while preserving user convenience by eliminating manual calibration steps.
Solution Approach 2:
Calibration parameters are pre-encoded into a compact pattern that can be quickly retrieved and applied. This preliminary preparation of calibration data enables rapid automatic calibration, allowing frequent calibration to maintain accuracy without burdening the user with time-consuming manual procedures.
3Extent of automation
If automatic calibration is implemented, then user intervention is reduced, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical calibration operations with an automated sensing and processing system. A sensor array detects the encoded optical or electromagnetic pattern on the calibration storage device, and a processor automatically decodes and applies the calibration data, substituting complex manual procedures with automated electronic systems that reduce user intervention.
Solution Approach 2:
An encoded pattern on a calibration storage device serves as an intermediary that carries calibration information in a compact, machine-readable form. This intermediary enables automatic calibration by providing a bridge between the calibration data and the device's processing system, allowing automated retrieval and application without direct user involvement.
4Reliability
If physical electrical contacts are used for calibration, then data transfer is reliable, but device invasiveness increases
Solution Approach 1:
The patent replaces physical electrical contacts with non-contact sensing methods. A sensor array detects the encoded pattern through optical or electromagnetic fields without making physical contact with the calibration storage device, thereby eliminating invasive disassembly while maintaining reliable data transfer through field-based detection.
Solution Approach 2:
An encoded pattern on a calibration storage device acts as a non-contact intermediary for data transfer. The pattern encodes calibration information that can be read remotely by a sensor array using optical or electromagnetic fields, eliminating the need for physical electrical contacts and invasive connections while ensuring reliable data transmission.
