Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If transfer heads and receiving substrates are used with variations in flatness and thickness, then manufacturing process is simpler, but distance uniformity deteriorates leading to improper component transfer
Solution Approach 1:
The system dynamically adjusts the distance between transfer heads and receiving substrates using actuators that can modify positioning in real-time based on measured variations, allowing the system to adapt to manufacturing tolerances while maintaining precise component transfer
Solution Approach 2:
The system incorporates monitoring signals that measure the actual distance between transfer heads and receiving substrates, feeding this information back to control actuators that adjust positioning to compensate for flatness and thickness variations, thereby resolving the contradiction between manufacturing simplicity and transfer precision
2Manufacturing precision
If actuators are added to deform transfer heads or receiving substrates, then distance uniformity is improved, but device complexity increases
Solution Approach 1:
The system applies deformation locally at specific points on transfer heads or receiving substrates using targeted actuators, rather than requiring global adjustment mechanisms, thereby achieving distance uniformity with minimal added complexity
Solution Approach 2:
The system changes physical parameters such as the shape or position of transfer heads and receiving substrates through actuator-induced deformation, allowing dynamic adjustment of distance uniformity without fundamentally redesigning the entire transfer mechanism
