Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional 3D printing methods are used for electric vehicle components, then manufacturing simplicity is maintained, but manufacturing precision and reliability of electrical connections deteriorate
Solution Approach 1:
The 3D printing process is divided into distinct segments: conventional printing for non-conductive parts, and electrostatic printing for conductive parts. This segmentation allows each method to be optimized for its specific function, achieving precise electrical connections without complicating the entire manufacturing process.
Solution Approach 2:
Electrostatic charging serves as an intermediary mechanism between the printing head and conductive material. By charging the printing head, the system enables precise deposition of conductive materials for electrical connections without requiring complex mechanical positioning systems.
2Manufacturing precision
If multiple materials are used for different component requirements, then manufacturing precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
Different printing methods are applied to different regions of the component: conventional printing for non-conductive structural parts and electrostatic printing for conductive electrical parts. This local differentiation achieves precise component properties while maintaining manufacturing simplicity through a unified system that automatically selects the appropriate method.
Solution Approach 2:
The 3D printing system is designed with multi-functionality to perform both conventional and electrostatic printing using the same basic apparatus. This universality allows multiple materials and methods to be integrated without requiring separate manufacturing lines, thus maintaining ease of manufacture.
3Reliability
If conventional printing methods are used for all components, then ease of manufacture is maintained, but reliability of electrical connections deteriorates
Solution Approach 1:
The printing system dynamically adapts its method based on the material being deposited. When conductive material requiring electrical connections is detected, the system automatically switches to electrostatic printing mode, ensuring reliability without manual intervention or reducing overall production efficiency.
Solution Approach 2:
The system changes key printing parameters such as electrostatic charge voltage and material flow rate when switching to conductive materials. These parameter adjustments ensure reliable electrical connections while maintaining high production efficiency through automated control.
