Problem and Customer Contact Prof. David Saiia of Ithaca College—Bottle Peeler Product description Device to clamp and bind PET bottle strips to be used as roofing material. • Problem • Need for alternative roofing to thatch for villages in Ecuador
Design • Heated nails that penetrate plastic powered by iron • Binding method • Pointed tip forms bond at rim of holes • Mock-ups to test automation of hole binding
Is Heating the Best Option? Need localized heat ~200°C Using soldering iron: 25 Joules/hole ~$.01/m2 Heat loss due to fins in iron mock-up Alternatives to heat Sewing Other mechanical fasteners (e.g. staples)
Other Unresolved Issues General Issues How to clean binding device? Need to clamp overall setup during binding process Need to test shear strength Thatch Specific Issues Must not trap heat inside house Must not be permeable to rain
Conclusion Heat used as binding method is feasible, but how can our design use heat more efficiently? We need to explore other options for joining plastic strips.
