Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning and storage of control member positions is performed, then the system can establish reference positions and operation ranges, but the user's work becomes time-consuming and labor-intensive
Solution Approach 1:
The control member automatically returns to its reference position using the electric drive unit and position detection unit, eliminating the need for manual positioning. The system self-calibrates by detecting the neutral position and automatically establishing operation ranges based on mechanical stop positions, making the system perform the setup work itself rather than requiring user intervention.
Solution Approach 2:
Manual mechanical positioning is replaced with an automated electromechanical system. The electric drive unit provides automated movement, the position detection unit provides automated position sensing, and the control unit processes the data to automatically establish operation ranges, substituting the entire manual mechanical adjustment process with an automated electromechanical system.
2Reliability
If manual control member positioning is performed, then reference positions can be stored, but the operation complexity increases due to multiple manual adjustment steps
Solution Approach 1:
The system automatically detects the neutral position of the control member and uses this as the reference position, eliminating the need for manual positioning. The electric drive unit automatically moves the control member to extreme positions to detect mechanical stops, and the control unit processes this data to automatically establish operation ranges, making the setup process simple and reliable.
Solution Approach 2:
The position detection unit continuously monitors the control member position and provides feedback to the control unit. During setup, the system detects feedback signals from mechanical stops and the neutral position, using this feedback information to automatically calculate and establish accurate operation ranges without requiring manual intervention.
3Ease of operation
If automated electric drive unit is used for control member displacement, then manual positioning work is eliminated, but the device complexity increases
Solution Approach 1:
The electric drive unit serves multiple functions: it positions the control member during normal operation, automatically returns the control member to the reference position, and assists in establishing operation ranges during setup. The position detection unit similarly serves multiple functions including detecting current position, detecting neutral position, and detecting mechanical stop positions. This multi-functionality justifies the added complexity by eliminating manual positioning work.
Solution Approach 2:
The automated system performs self-calibration and self-setup functions. The electric drive unit automatically moves the control member to extreme positions to detect mechanical stops, and the control unit processes this information to automatically establish operation ranges. This self-service capability eliminates manual positioning work while the added complexity is offset by the elimination of ongoing manual adjustment requirements.
