OUR TEAM Name: Blake McCal Name: Michael Finocchiaro Name: Chris Zakanycz Name: Nick Faas Name: Jonathan Planten LAB 2 WRITE-UP Device Image and Description Technical and Clinical Feasibility Technical Feasibility What are the technologies needed? a). plastic milling machine b). Metal mill for external housing, welding may be needed depending on how we decide to attach the bottom plane to the arc shaped upper housing. c). plastic injection molding for pieces related to the button and trigger system d). stainless steel, aluminum welding machine for canister containing the medicine What are the challenges? a). We are concerned that a flat, ellipse shaped canister will expand around the areas with smaller slope. Cylindrical canisters don’t have this issue since the pressure is equalized in 360*, reducing the chance of unwanted expansion of the walls. b). Metered dosing issues. We are unsure about how to incorporate a metered dosing function into a flat ellipse shaped canister What could go wrong? a). We may be unable to create the canister in the desired shape. We want a canister that can fit inside a sleek, arced housing attached to the back of the phone case. Typical inhaler designs involve cylindrical shaped canisters, so we will need to spend time in R&D testing innovative canister designs b). If the metered dosing feature fails, people will be unable to administer medicine to themselves. This is obviously an extreme concern since this sort of failure could lead to cardiac arrest or death. Clinical Feasibility Given the technical feasibility, would it work in the clinic? a). Based on the technical feasibility, the product should work in a clinical setting because the manufacturing plan is logical. What are clinical risks? a). The metered dose could fail b). The trigger button could get jammed c). Explosion due to build up of pressure in canister Have similar products been in a clinical trial? a). No current model to compare to Market Analysis Value Creation a). Our product delivers peace of mind as well as functionality for asthma affected individuals. Many children carry a smart phone all day, yet don’t have access to their inhaler when they need it. If customers had a backup, emergency inhaler attached to their phones they would rarely be caught without their medicine. Manufacturing Cost a). Phone case: $3k for a mold, plus $0.10 - $0.50 per unit for materials b). Canister housing: finished dimensions 0.5” x 2.4” x 4.0” (H x W x L). -Aluminum housing: 6061 Aluminum flat bar; 0.5” x 3” x 4” = $2.53 (metals depot) -Stainless steel housing: 304 Stainless Steel Flat; 0.5” x 3” x 4” = $6.24 (metals depot) c). Canister containing the medicine 0.5” OD x 4” = $0.41 (aluminum), $0.80 (stainless) d). Miscellaneous hardware: -Activation button: 0.5” x 0.5” x 1.0” piece of metal (aluminum or stainless) -Safety mechanism: 0.25” x 0.25” x 1.0” piece of metal -Retractable mouthpiece: 0.5” x 0.5” x 1.0” piece of metal -Metal track to hold canister in place: 0.3” x 2.5” x 4” piece of metal Total metal required for misc hardware: 3.56 cu. in Since this is a variable cost, we estimate it as $2 (aluminum), $6 (stainless steel) Cost of phone case + aluminum housing + hardware = $5.44 per unit (max) Cost of phone case + stainless steel housing + hardware = $13.54 per unit (max) Sales Price (6061 Aluminum) $27.20 (304 Stainless steel) $67.70 Market Size Fundability Discussion
