Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical systems (barcode and camera) are used for position determination, then position monitoring is possible, but the system requires frequent cleaning in dusty environments
Solution Approach 1:
The patent replaces the optical measurement system (camera and barcode) with a magnetic field-based detection system. Magnetic field sensors (Hall sensors) detect the position of the clamping device by sensing magnetic fields generated by magnets embedded in the console, eliminating the need for optical components that require cleaning in dusty environments.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary medium for position transmission. Magnets embedded in the console generate magnetic fields that extend into the space around the console, allowing the sensor on the clamping device to detect position without direct optical contact, thus avoiding dust contamination issues.
2Reliability
If magnetic field generating devices are used for position determination, then reliable position detection in dusty environments is achieved, but device complexity increases
Solution Approach 1:
The patent uses magnetic field patterns as a simplified copy or representation of position information. Instead of complex optical encoding like barcodes, simple magnets embedded in the console create magnetic field patterns that directly correspond to position, which are detected by Hall sensors on the clamping device.
Solution Approach 2:
The patent changes the physical parameter used for position detection from optical reflection (camera-based) to magnetic field strength (Hall sensor-based). This parameter change enables reliable detection in dusty environments where optical systems fail, as magnetic fields are not scattered by dust particles.
