Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray input apparatuses face challenges in accurately reflecting an operator's intentions for calibration control, particularly when used in wireless X-ray imaging systems, due to variability in environmental conditions and the need for precise capacitance threshold settings.
Innovation Solution
The X-ray input apparatus incorporates a touch sensor, radiation button, and input controller that perform calibration control by determining the capacitance threshold value based on the sensor's output and environmental conditions, ensuring accurate calibration only when the device is accommodated in a holder and specific commands are input, thereby enhancing operational accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration control is performed continuously or frequently, then the capacitance threshold value can be kept accurate, but unnecessary calibration operations increase and operational efficiency decreases
Solution Approach 1:
The system performs calibration control in advance under predetermined conditions (when the input apparatus is accommodated in the holder and specific button patterns are detected). This preliminary calibration ensures the capacitance threshold is accurate before actual X-ray operation begins, eliminating the need for frequent calibration during operation and thus maintaining both accuracy and efficiency.
2Ease of operation
If the touch sensor capacitance threshold is set too low, then touch sensitivity increases, but false detection of touch input increases
Solution Approach 1:
The system uses feedback from the calibration control process to dynamically determine the capacitance threshold value. By measuring the actual capacitance characteristics of the touch sensor under known conditions and adjusting the threshold accordingly, the system optimizes the balance between sensitivity and false detection rate based on real sensor performance rather than fixed predetermined values.
3Adaptability or versatility
If calibration control is performed without verifying device position, then calibration can be done anytime, but calibration may be performed when the device is not in the holder causing inaccurate calibration
Solution Approach 1:
The system checks the accommodation status of the input apparatus in the holder as a preliminary condition before performing calibration control. This ensures that calibration only occurs when the device is in the correct position, guaranteeing calibration accuracy while maintaining operational flexibility through automated condition verification.
