Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of operating conditions is performed based on user experience and intuition, then the system can be operated, but the manufacturing precision and stability of product quality deteriorate due to user skill dependence
Solution Approach 1:
The system performs self-diagnosis and self-adjustment by automatically detecting resin state parameters (temperature, viscosity, flow rate) and autonomously optimizing operating conditions without requiring skilled manual intervention, enabling the system to serve itself in maintaining optimal manufacturing precision
Solution Approach 2:
A feedback control mechanism continuously monitors resin state parameters through sensors and automatically adjusts operating conditions based on real-time data, creating a closed-loop system that maintains consistent product quality regardless of user skill level
2Manufacturing precision
If multiple operating conditions are manually adjusted to optimize resin state, then product quality can be improved, but the device complexity and time required for initial setting increase
Solution Approach 1:
The system performs preliminary automated detection and optimization of operating conditions before actual production begins, using pre-programmed parameter ranges and automatic tuning to establish optimal settings without requiring complex manual adjustment procedures
Solution Approach 2:
The system automatically changes multiple operating parameters (temperature, pressure, flow rate) based on detected resin state, using programmed parameter adjustment rules to optimize conditions without manual intervention while managing system complexity through automated control logic
3Reliability
If automated sensor-based control is implemented, then manufacturing precision and stability improve, but the device complexity increases
Solution Approach 1:
Sensors detect resin state parameters and feed this information back to the control system, which automatically adjusts operating conditions, creating a reliable closed-loop control mechanism that improves consistency while managing complexity through integrated automation
Solution Approach 2:
Manual mechanical adjustment is replaced with automated electronic sensing and control systems, using electronic parameters and computer-controlled actuation to achieve more precise and reliable operating condition optimization
