Problem Statement In order to simultaneously collect emissions and transport undisturbed casts for analysis, current hollow cast models will be combined with the existing side stream smoking machine. Device will operate using acquired data from the wPSMD. Unit needs to be self-contained, portable, fit on a workbench, and user friendly. The unit must also be production ready for identical machines in other labs. During operation smoke needs to be ventilated responsibly and the unit must be interfaced with LabVIEW. Team 14054

Problem Statement(Bullet Form) Smoke single Cigarette Smoke travels through main-stream lung casting while the side-steam machine captures the remaining smoke Smoke that travels through the lung casting will be recirculated through the side-stream machine (2nd hand smoke) Unit will fit on a portable cart Samples will be taken to the NTID lab for analysis Team 14054

Critical Design Challenges(C.D.C) Pump- Eric Valve- Chris Tubing- Chris Lighting- Gideon Humidifier- Megan Team 14054

C.D.C - Pump Best solution- OEM 570 Syringe Pump Pros- LabVIEW programmable Appropriate mimic of a lung Simple to use/set up Runs by itself after set up Cons- Expensive ~$650 Only for Main Stream testing. Need separate pump for Side stream machine Team 14054

C.D.C – Pump, Side Stream Best solution- Electric vacuum pump Pros- Already have High vacuum Oil free Cons- Expensive (if had to buy) Continuous run, need to limit flow Team 14054

C.D.C – Pump, Smoking Profile Team 14054

C.D.C - Valve Best solution- 2-way check valve Pros- Inexpensive ~ $5.00 Corrosion resistance ~ polypropylene Easy to clean Low cracking pressure ~ 1 psi Rubber hose connections ~ range of sizes Cons- No built in flow sensor Team 14054

C.D.C - Tubing Best solution- standard size/material tubing Pros- Professional looking Easy disassembly for maintenance, testing, and cleaning “1 size fits all” Constant flow rate Cons- Need for reducers or enlargers Replacement of all old tubing Polypropylene Tubing Approx. $.37/foot FDA approved Tube to Pipe Adapter Approx. $2.25 each Team 14054

C.D.C - Lighting Best solution- electric cigar lighter Pros- Remotely activated/autonomously controlled Flexibility No human interaction Safety using fuses or biased impedance Non chemical use Cons- Lighting Difficulties Team 14054

C.D.C - Lighting Team 14054

C.D.C - Humidifier Best solution- Ecoflo Pros- Easy to control Built in feedback system Cons- Large Unit Implementation Previous Unit Pros- Easy to implement, small footprint Cons- No feedback, hard to control Team 14054
