Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional mechanical leveling techniques are used, then the build platform can be leveled, but the process requires high user interaction, skill, and multiple iterations taking 30-60 minutes
Solution Approach 1:
The patent replaces manual mechanical leveling operations with an automated motorized system. The build platform is mounted on a motorized vertical actuator that automatically adjusts the platform height in the Z-axis direction, eliminating the need for manual screw adjustments and repeated measurement- adjustment cycles.
Solution Approach 2:
The system performs self-leveling through automated feedback control. Sensors detect the actual position and levelness of the build platform, and the control system automatically commands the motorized actuator to make necessary adjustments, enabling the system to level itself without requiring operator skill or multiple iterations.
2Manufacturing precision
If conventional mechanical leveling systems are used, then the build platform can be adjusted, but the build plates are heavy and make removing and adjusting them difficult
Solution Approach 1:
The patent replaces heavy mechanical build plates with a motorized build platform assembly. The platform is mounted on a vertical actuator that provides motorized height adjustment, eliminating the need to manually handle and reposition heavy plates for leveling adjustments.
Solution Approach 2:
The system transitions from static heavy plates to a dynamic motorized platform. The vertical actuator enables the build platform to move automatically in the Z-axis direction, providing dynamic adjustment capability that eliminates manual intervention and reduces operational difficulty.
3Measurement precision
If manual leveling adjustments are performed, then the build platform can be leveled, but it requires high user skill and multiple iterations
Solution Approach 1:
The patent replaces complex manual leveling procedures with automated motorized control. The system uses sensors to detect platform position and levelness, then automatically commands the vertical actuator to make precise adjustments, eliminating the need for operator skill and multiple iterative adjustments.
Solution Approach 2:
The system implements automated feedback control for leveling. Sensors continuously monitor the build platform's position and levelness, providing real-time feedback to the control system, which then automatically adjusts the motorized actuator to achieve and maintain the desired level state, reducing process complexity.
