Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manufacturing processes are used to create inserts with holes, then manufacturing precision can be maintained, but device complexity and production cost increase
Solution Approach 1:
The patent replaces complex mechanical manufacturing processes (drilling, machining holes in inserts) with a simpler mechanical cutting process. The cutting tool directly forms the fluid passage channels in the insert body through a single cutting operation, eliminating the need for separate hole-drilling operations and reducing manufacturing steps while maintaining dimensional accuracy.
Solution Approach 2:
The patent changes the manufacturing approach from creating separate holes to forming integrated channels through cutting. By modifying the insert design to have channels that can be directly cut rather than drilled, the manufacturing process becomes simpler while achieving the same functional result of fluid passage.
2Manufacturing precision
If complex manufacturing processes are used, then manufacturing precision improves, but productivity decreases
Solution Approach 1:
The patent substitutes multiple mechanical operations (drilling, reaming, tapping) with a single cutting operation. The cutting tool directly forms the fluid channels in one pass, significantly reducing manufacturing time while maintaining the precision needed for consistent spray patterns across production batches.
Solution Approach 2:
The patent segments the manufacturing process into a single cutting operation rather than multiple sequential operations. By designing the insert with channels that can be formed in one cutting pass, the production cycle time is reduced while the segmented channel design ensures consistent fluid flow and spray pattern reproduction.

Implementation Method 1
The nozzle is adapted to form a jet or spray of a fluid... the shape and dimensions of the outlet orifice... allowing for the creation of a conical spray pattern using simple and affordable manufacturing methods, with angles and shapes that optimize fluid dynamics for consistent performance
Implementation Method 2
the fluid entering the nozzle passes through the insert and flows into the vortex chamber in which it takes on a rotary motion... the fluid exiting through the orifice, being subjected to centrifugal force, is broken down into drops
