Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual placement of detection element is used, then flexibility is improved, but time consumption increases and positioning accuracy deteriorates
Solution Approach 1:
The detection element automatically positions itself using a pivoting mechanism driven by a motor, eliminating the need for manual placement. The self-positioning system uses sensors to detect its own state and adjusts accordingly, resolving the contradiction between flexibility and time consumption.
Solution Approach 2:
The detection element is designed with a pivoting component that allows dynamic adjustment of its position. The motor-driven mechanism enables the detection element to move between different positions automatically, providing both flexibility and time efficiency.
2Adaptability or versatility
If manual placement of detection element is used, then flexibility is improved, but calibration accuracy deteriorates
Solution Approach 1:
The system incorporates sensors that detect the position and orientation of the detection element. This feedback is used by the control unit to determine whether the detection element is in the correct position for calibration, ensuring high calibration accuracy while maintaining flexibility through automated adjustment.
Solution Approach 2:
The manual mechanical placement process is replaced with an automated motor-driven pivoting mechanism. This substitution eliminates human error in positioning while maintaining the flexibility to adjust the detection element's position as needed.
3Device complexity
If detection element position is not confirmed, then device complexity is reduced, but calibration reliability deteriorates
Solution Approach 1:
Sensors provide feedback about the detection element's position to the control unit, which determines whether calibration should proceed. This feedback mechanism ensures calibration reliability without significantly increasing device complexity, as the sensors and control logic are integrated into the existing system.
