Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional film forming techniques are used, then film formation can be achieved, but film thickness control and quality uniformity deteriorate
Solution Approach 1:
The patent divides the film formation process into multiple discrete liquid discharge steps, with multiple liquid discharge heads positioned at different locations. Each head applies liquid to specific regions, and the process is segmented into predetermined stages. This segmentation enables precise control of film thickness and uniformity across large areas by independently managing different regions through controlled liquid discharge patterns.
2Area of stationary object
If multiple liquid discharge heads are used, then film coverage area increases, but system complexity increases
Solution Approach 1:
The patent employs multiple liquid discharge heads that can be positioned at different locations along the conveyance direction, allowing a single apparatus to handle both small and large area film formation requirements. The system is designed to be versatile by enabling selective activation and positioning of discharge heads based on the specific application needs, thus achieving multi-functionality without proportionally increasing overall system complexity.
