We're a consumer electronics brand (SYPS Hydration) building compact hydration appliances. We need a mechanical engineer to design a mounting solution for a non-threaded quick connect fitting in a hard-walled water reservoir.
• *The Problem:**
We need to securely mount a non-threaded quick connect fitting into our hard reservoir using a solution that is watertight, food-safe, and optimized for fast assembly during production. We have existing grommets that may work as part of the solution, but we're open to the best approach.
• *Constraints & Requirements:**
- All materials must be food-grade / potable water safe (FDA compliant)
- Strongly prefer a solution using common, off-the-shelf hardware (bulkhead fittings, grommets, O-rings, retaining clips, etc.) to avoid custom tooling costs
- If custom hardware is required, that's acceptable — but please justify why off-the-shelf won't work
- Solution must be designed with assembly time in mind — we're building at 1,000+ unit volumes and need something a line worker can install quickly and consistently
- Must create a watertight seal under normal use conditions (low pressure, gravity or pump-fed)
- Must be compatible with the existing reservoir geometry and grommet (CAD files will be provided to selected candidates)
• *Deliverables:**
1. Final CAD files (SolidWorks or STEP) of the mounting solution integrated with the reservoir
2. Bill of Materials (BOM) with specific part numbers and sourcing links (McMaster-Carr, Amazon, Alibaba, etc.)
3. Assembly instructions — step-by-step with estimated assembly time per unit
4. Sourcing links for all hardware components
5. Brief design rationale explaining tradeoffs and why this approach was selected
• *What We'll Provide:**
- CAD files of the reservoir and existing grommet
- Quick connect fitting specs
- Context on the product and how the reservoir fits into the overall assembly
- Feedback and iteration as needed
- parts for prototyping (reservoir, quick connect, existing grommets)
• *Ideal Candidate:**
- Experience with product design for consumer hardware or appliances
- Familiar with food-grade material requirements and sealing solutions
- Practical DFM mindset — you think about assembly time, cost, and sourcing, not just geometry
- Comfortable working in SolidWorks (preferred) or can deliver clean STEP files
- Responsive communicator — this is a focused project, not a long engagement
• *Budget:** $200–$500 fixed price (scope-dependent — if your approach requires more, explain why in your proposal)
• *Timeline:** Looking to finalize within 1–2 weeks
• *To Apply:**
Please include in your proposal:
1. A brief description of how you'd approach this problem
2. 1–2 examples of similar mechanical design work (mounting, sealing, fluid-path, consumer hardware)
3. Your estimated timeline and fixed price
We'll share CAD files with shortlisted candidates before starting.
