I have an initial hand-drawn concept for a new manual valve that will sit behind a residential shower trim plate. The idea is simple: give the user precise flow control while all but eliminating the chance of hidden leaks. What I need now is an engineer or product designer who can turn that sketch into a complete, production-ready solution. The core requirements are clear: • Manual valve system only – no thermostatic or digital electronics involved. • Components to be moulded in plastic; material selection should balance cost, durability, and resistance to hot, chlorinated water. • Primary function is flow control; temperature balancing will be handled upstream. • Leak-prevention is critical, so gasket selection, seal geometry, and any weep holes or moistu...

My facility is a large industrial complex that runs multiple gas turbines and high-capacity cooling fans. To demonstrate full compliance with local and national environmental noise limits, I need a complete acoustic survey followed by predictive modeling. Because no baseline data exist, the work begins with an on-site measurement campaign near Williston ND. You will need to identify all significant sound sources, take calibrated octave-band readings at representative operating conditions, and log meteorological data for traceability. Once the raw data are secured, the next step is to build a 3-D propagation model—CadnaA, SoundPLAN, or a similar ISO 9613-compatible tool is fine—so that I can see current sound power levels, verify boundary compliance, and test mitigation scena...

I need fully-parametric gear models and some parts created in Autodesk Fusion 360.
