Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nozzle assemblies in dispensing systems suffer from manufacturing defects due to over-compression during assembly, leading to degraded dispensing capabilities.
Innovation Solution
A nozzle insert with a specific design featuring a body with angled and orifice walls, a fluid passageway, and raised portions to mitigate over-compression issues, ensuring consistent fluid flow and improved manufacturability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If nozzle inserts are assembled using conventional methods, then assembly speed is maintained, but manufacturing precision deteriorates due to over-compression
Solution Approach 1:
The nozzle insert is pre-formed with an integrated flange and positioning features before assembly. The flange is pre-configured with specific thickness and diameter dimensions that enable precise positioning on the actuator post, eliminating the need for post-assembly adjustments and preventing over-compression issues
Solution Approach 2:
The design specifies precise dimensional parameters for the flange (thickness of 0.030-0.060 inches, diameter extending 0.125-0.375 inches beyond the post) and positioning features (protrusions matching cavities) that change the assembly from a compression-fit to a precision-mated connection, maintaining manufacturing precision without increasing assembly difficulty
2Manufacturing precision
If nozzle insert design is simplified for easier manufacturing, then ease of manufacture improves, but manufacturing precision deteriorates due to tolerance accumulation
Solution Approach 1:
The nozzle insert is segmented into distinct functional zones: a flange portion for mounting, a body portion for fluid containment, and a nozzle portion for dispensing. Each segment can be manufactured with optimized tolerances for its specific function, preventing tolerance accumulation while maintaining overall precision
Solution Approach 2:
The flange serves multiple functions simultaneously: it provides mounting attachment to the actuator post, positions the nozzle insert axially and radially, and distributes compression forces. This multi-functionality reduces the need for additional separate components, maintaining simplicity while achieving precision

AI summary
A nozzle insert includes a body with a front portion and a rear portion, a rim, and a nozzle portion that includes an angled wall and an orifice wall. The angled wall extends radially inward and laterally forward from the rim, and the orifice wall intersects with the angled wall and defines a nozzle orifice. The orifice wall extends both laterally forward and rearward from the intersection with the angled wall. A cylindrical inner surface of the orifice wall defines a fluid passageway that terminates at a forward end at the nozzle orifice and at a rearward end spaced rearward of a forwardmost end of the angled wall.
