Universal “EcoSpray” Nozzle – Industrial Design + Mechanical Engineering Description: Looking for an engineer who can design a high-reliability trigger sprayer that fits 38mm Gatorade-style bottle threads, prevents sputtering, and works at multiple angles. You will create all concepts, sketches, internal mechanisms, and production-ready CAD using only a functional specification—no existing drawings or samples are provided. Project Overview: EcoSpray is a reusable spray head designed to attach directly to Gatorade-style 38mm bottle threads. The goal is a mechanically simple, durable sprayer that provides consistent spray performance, works reliably when the bottle is tilted, avoids sputtering or “dead pulls,” and leaves minimal unused liquid. You will design this entirely from the performance requirements below. Core Requirements: 1. Universal Bottle Compatibility • Must securely fit standard 38mm Gatorade-style bottle neck threads (38/400 equivalent). • Designer is responsible for referencing/sourcing the correct neck standard. • Must form a strong, leak-proof connection. 2. Consistent, Reliable Spray • Must spray smoothly when upright, tilted, or horizontal. • Must maintain a stable spray pattern without sputtering or interruptions. • Should remain usable down to the last 5–10% of liquid. 3. Anti-Sputter Internal Flow Path • Internal geometry must avoid air-trap pockets. • Use a slightly larger dip-tube diameter than typical cheap sprayers. • Include a small plenum/buffer chamber above the dip-tube inlet to stabilize suction. • Flow path must be smooth and continuous, without abrupt transitions. • Must prevent the common “spray → sputter → nothing → spray” behavior. 4. Mechanical-Only Operation • Manual trigger only. • Passive internal channels/valves allowed. • No electronics, motors, pumps, or pressurized components. 5. Manufacturability • All parts must be suitable for injection molding. • Durable and realistic for long-term consumer use. • Geometry should be 3D-printable for prototyping. Deliverables: • Full CAD models (STEP/IGES + native files). • Complete assembly model. • Exploded and sectional views showing internal geometry. • Correct 38mm threaded collar design. • Brief explanation of how the design maintains angle performance, avoids sputtering, and minimizes leftover liquid. Designer Responsibilities: • Produce concept sketches and design explorations. • Develop the external form (nozzle, trigger, body). • Engineer the internal flow path, plenum, and dip-tube interface. • Handle all mechanism development and dimensioning independently. • Work entirely from this functional specification (no drawings or samples provided). Ideal Freelancer: • Experience with sprayers, pumps, atomizers, fluid-handling mechanisms, or similar consumer products. • Strong mechanical engineering background. • Skilled in injection-molded product design. • Capable of both concept ideation and production-ready CAD. Budget: Looking for affordable engineering talent. Experience with spray mechanisms or fluid-related consumer products will be prioritized.

Hello, I understand you're looking for an engineer to design a unique trigger sprayer that fits a standard 38mm bottle, aimed at providing consistent performance with no sputtering. My approach will focus on creating a simple yet effective design that meets your requirements for reliability and manufacturability. I will develop all concepts and mechanisms needed to ensure smooth operation at various angles while also minimizing product waste. I'll provide detailed CAD models and sketches that reflect the functional needs from scratch, without relying on existing designs. What specific materials are you considering for the production of the nozzle and trigger? Are there any regulatory or safety standards we need to keep in mind during the design process? What testing methods do you plan to use to evaluate the nozzle's performance? Are there particular design aesthetics you want to achieve for the external form? What is your target production volume for the sprayers? Do you have a preferred timeline for the completion of the project? How will you handle any potential prototype iterations? Is there a specific budget range you are aiming to stay within for production costs? Thanks,
