Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification of material melting is required before molding, then molding quality can be ensured, but user burden increases and operation becomes complex
Solution Approach 1:
The system performs self-verification of material melting status through automatic torque detection. The control section monitors torque values during the standby process to determine if material has completely melted, eliminating the need for manual user verification while ensuring molding quality.
Solution Approach 2:
The system implements feedback control by continuously monitoring torque values applied to the ejection amount adjustment section. Based on the detected torque values during the standby process, the control section automatically determines material melting status and controls the molding process accordingly, replacing manual verification with automated feedback-based decision making.
2Ease of operation
If material melting is not completely verified before molding, then operation becomes simpler, but drive motor overload occurs and molding quality deteriorates
Solution Approach 1:
The system performs preliminary verification of material melting status during the standby process by detecting torque values before the molding process begins. This preliminary action ensures material is completely melted before ejection starts, preventing motor overload and quality issues while maintaining simple operation for the user.
Solution Approach 2:
The system replaces manual mechanical verification with automated torque detection. The control section uses torque value monitoring to automatically determine material melting status, substituting manual user actions with automated sensor-based detection to ensure reliability without complicating operation.
3Ease of operation
If torque detection is implemented to automatically verify material melting, then user burden is reduced, but device complexity increases
Solution Approach 1:
The ejection amount adjustment section serves multiple functions: it controls plasticized material ejection during molding and simultaneously acts as a torque sensor to detect material melting status. This multi-functionality reduces device complexity by reusing existing components for dual purposes rather than adding separate detection devices.
Solution Approach 2:
The control section performs self-diagnosis by monitoring torque values during the standby process to automatically determine material melting status. This self-service capability eliminates the need for complex external verification systems while reducing user burden through automated decision making.
