Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a series superposition process is used for double-sided coating, then labor cost is reduced, but the passing path becomes circuitous and long, causing significant material waste
Solution Approach 1:
The patent combines two separate single-sided coating processes into one integrated double-sided coating device, where coating units are arranged on both sides of the substrate passage. This merging allows simultaneous coating of both sides in a single pass, eliminating the need for sequential processing and reducing the circuitous passing path while maintaining labor efficiency.
Solution Approach 2:
The patent transitions from a single-sided sequential coating approach to a double-sided parallel coating approach by arranging coating units on both sides of the substrate passage. This dimensional change allows the substrate to be coated on both sides simultaneously in one pass, significantly shortening the passing path and reducing material waste.
2Productivity
If a series superposition process is used for double-sided coating, then coating can be completed at one time, but the material passing is difficult and lasts for a long time
Solution Approach 1:
The patent merges two sequential coating operations into a single integrated double-sided coating process. By arranging coating units on both sides of the substrate passage, the system achieves simultaneous coating of both sides in one pass, completing the coating process faster while reducing the time material spends in the system.
Solution Approach 2:
The patent implements continuous coating action on both sides of the substrate simultaneously through properly coordinated coating units. The coating, crosslinking, and curing processes continue without interruption on both sides, eliminating the sequential waiting time inherent in superposition processes and improving overall efficiency.
3Productivity
If a series superposition process is used for double-sided coating, then two coating procedures can be completed, but the equipment space becomes large and cannot be accommodated in ordinary factories
Solution Approach 1:
The patent combines two separate coating procedures into a single integrated double-sided coating device. By arranging coating units on both sides of a common substrate passage and using a single oven for drying both sides, the equipment achieves double-sided coating capability while occupying significantly less space than two separate single-sided coating lines.
Solution Approach 2:
The patent designs a universal double-sided coating device where a single oven serves dual purposes for drying both sides of the substrate. The coating units on both sides share common infrastructure including the substrate passage and drying chamber, enabling multi-functional operation that reduces overall equipment footprint while maintaining full double-sided coating capability.
4Productivity
If a series superposition process is used for double-sided coating, then coating can be performed on both sides, but the material needs to pass through many supporting guide rollers, increasing resistance and causing material deformation
Solution Approach 1:
The patent merges the support functions into a simplified guide structure that spans the entire double-sided coating device. Instead of multiple separate guide rollers for each coating side, a unified guide mechanism provides support for the substrate passage, reducing the number of contact points and minimizing resistance while preventing material deformation.
