Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control is used for rotary pressure devices, then ease of operation is improved, but reliability deteriorates due to operator error and lack of precise control
Solution Approach 1:
The patent replaces manual mechanical control with an electrical control system comprising a motor, power control unit, central processing unit, and rotational speed sensor. This substitution eliminates operator error while maintaining ease of operation through automated control mechanisms that precisely regulate rotational speed and interrupt power supply when abnormalities are detected.
2Reliability
If automated control with abnormality detection is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control system where the rotational speed sensor continuously monitors motor speed and feeds this information to the central processing unit. The CPU compares the measured speed against predetermined thresholds and automatically interrupts power supply when abnormality is detected, creating a closed-loop control system that enhances reliability without requiring complex external monitoring equipment.
Solution Approach 2:
The control system is designed to autonomously detect abnormalities and interrupt operation without external intervention. The central processing unit self-monitors rotational speed through the sensor and automatically takes corrective action by controlling the power control unit, enabling the system to serve itself in maintaining safe operation.
3Manufacturing precision
If precise rotational control is implemented, then manufacturing precision is improved, but loss of time increases due to additional control mechanisms
Solution Approach 1:
The patent incorporates predetermined rotational speed thresholds and control parameters into the system before operation begins. The central processing unit is pre-programmed with safety criteria and automatic interruption criteria, allowing the system to immediately respond to abnormalities without requiring real-time calculation or decision-making during critical operations, thus minimizing time loss while maintaining precision.
