Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple liquid streams are expelled under pressure from orifice openings surrounded by walls, then liquid delivery is sufficient, but pattern definition is poor and residue buildup occurs
Solution Approach 1:
The liquid delivery system is segmented into multiple discrete liquid streams rather than using a single broad flow. Each stream is independently controlled and directed through separate conveyance channels, allowing precise patterning while minimizing unnecessary liquid application and residue buildup.
Solution Approach 2:
The walls surrounding the orifice openings are removed entirely. Instead of enclosed orifices, the system uses open-faced liquid streams that are conveyed through defined channels without circumferential walls, eliminating the complexity and residue accumulation associated with enclosed structures.
2Ease of operation
If orifice openings are surrounded by walls for structured liquid delivery, then liquid flow is controlled, but system complexity increases
Solution Approach 1:
The circumferential walls surrounding each orifice opening are completely removed. Liquid flow control is achieved not by enclosed structures but by the geometry and positioning of open-faced liquid conveyance channels, significantly simplifying the system structure while maintaining operational control.
Solution Approach 2:
Liquid conveyance channels serve as intermediaries between the liquid supply and the substrate. These channels provide structured flow control without requiring enclosed orifices, acting as open pathways that guide liquid streams precisely while maintaining system simplicity.
3Manufacturing precision
If liquid streams are interrupted by transverse gas jets for pattern formation, then fine scale patterns are achieved, but liquid collection efficiency decreases
Solution Approach 1:
The system removes the need for complex gas jet interruption mechanisms by using selectively activatable liquid conveyance channels. Liquid streams are turned on and off directly at the source through channel activation rather than being interrupted mid-flight by transverse gas jets, maintaining fine scale pattern capability while improving liquid collection efficiency.

AI summary
An improved system for application of liquid streams to a substrate. The system incorporates open face flow channels for carrying the liquid away from fully enclosed flow segments prior to discharge along an unconstrained flow path. The present invention further provides an improved, self-aligning modular assembly for delivery of impingement jet to the liquid streams for diverting the direction of the liquid streams. The present invention further provides an improved arrangement for collection of the deflected liquid in response to application of the impingement jet without excess residue build-up.
