Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional manual leveling techniques are used, then the build platform can be leveled, but the process requires high user interaction, skill, and multiple iterations which is time-consuming
Solution Approach 1:
The patent replaces manual mechanical leveling operations with an automated motorized transmission system. The system uses a motorized actuator to automatically adjust the build platform position based on sensor feedback, eliminating the need for manual intervention and repeated measurement iterations while maintaining precision.
Solution Approach 2:
The patent implements a feedback mechanism where sensors continuously monitor the build platform levelness and transmit data to a control system. The control system processes this information and automatically adjusts the motorized transmission components to achieve and maintain the desired level state, reducing both time and skill requirements.
2Measurement precision
If conventional manual leveling techniques are used, then the build platform can be leveled, but the process is highly dependent on user expertise and skill
Solution Approach 1:
The patent enables the leveling system to perform self-service through automation. The motorized transmission system automatically executes leveling adjustments based on sensor feedback without requiring user expertise. The system self-regulates by continuously monitoring platform levelness and making corrective adjustments independently.
Solution Approach 2:
The patent replaces skill-dependent manual operations with an automated control system that uses sensors and motorized actuators. This substitution eliminates the need for user expertise in manual leveling techniques while maintaining or improving precision through consistent automated execution.
3Stability of the object's composition
If the build platform is heavy, then it provides stability during additive manufacturing, but it makes manual adjustments difficult
Solution Approach 1:
The patent replaces manual mechanical adjustment operations with an automated motorized transmission system. The motorized actuator can easily move the heavy build platform without requiring human physical effort, maintaining stability while enabling simple automated adjustments through electrical control rather than manual manipulation.
4Measurement precision
If multiple iterations of manual leveling are performed, then the build platform can achieve a level state, but the process becomes time-consuming
Solution Approach 1:
The patent implements continuous automatic leveling monitoring and adjustment during the additive manufacturing process. Rather than performing discrete manual leveling iterations before manufacturing, the system continuously monitors platform levelness and makes real-time adjustments, ensuring consistent precision throughout the manufacturing process and eliminating productivity losses from repeated manual intervention.
Solution Approach 2:
The patent uses continuous feedback from sensors to monitor build platform levelness during manufacturing. The control system processes this feedback and automatically adjusts the motorized transmission components as needed, eliminating the need for multiple manual measurement and adjustment iterations, thereby improving productivity while maintaining precision.
