Prototype Needed: Mechanical Engineer for Water-Control Bathroom Device

---

---

We are seeking a skilled engineer or designer to create a prototype for a device that automatically drains and refills toilet bowl water based on the position of the seat. This project requires a keen understanding of electronics, plumbing systems, and user-friendly design. The ideal candidate will collaborate with our team to ensure functionality and efficiency, ultimately providing a sustainable solution for water management in toilets. Experience with prototyping and product development is essential. WHAT YOU'LL BUILD -A wireless-triggered system that controls bowl water levels in tanked toilets -A hinge-mounted sensor or seat detection unit that communicates with a water control valve inside the tank -Compact, retrofit-friendly hardware (non-invasive installation) -Battery or weight-powered options preferred IDEAL EXPERIENCE -Toilet plumbing systems, flush valves, or small-scale water flow control -Consumer product prototyping (CAD + material selection) -Design for manufacturing (DFM) -3D printing or early-stage mockup creation Bonus: low-voltage electronics, sensors, or solenoid integration DELIVERABLES -CAD files (STEP or Fusion 360 preferred) -Functional prototype (or BOM and instructions for 3D printing/assembly) -Input on component sourcing (valves, sensors, etc.) WE PROVIDE -Product sketches -Patent filing in progress (your work will be covered under NDA & IP agreement) -Quick decisions — we’re ready to move fast Remote okay | Paid project with option for follow-up work Budget: $2,000–$5,000 for initial prototype Timeline: Flexible but ideally completed in 3–5 weeks keywords: toilet flush device, water-saving invention, mechanical product design, seat sensor, smart bathroom, CAD, DFM Interested?
