Voice of the Customer Design solutions for unused plastic bottles in Haiti for economic benefit:  Withstand the unpredictable and harsh environment  Support impoverished families and create labor  Make use of local materials  Design for ease of use Opportunities in Haiti External Factors EconomicsDurabilityEase of Use Material Requirements

Simplified Functional Decomp.  Overarching goal of project was so broad that it needed to be broken down into several sub-functions

Fruit Carrier: Concepts

Fruit Carrier: Feasibility No weaving skills in Haiti: One of Haiti's largest exports is clothing and accounts for over 50% of their exports. += Bottle thread breaks during weaving or use: A single strand of 1mm square cross- section bottle thread can hold 10.6 lbs. This falls within range of polyester thread with a similar gauge.

Roofing: Functional Decomp. & Eng. Requirements FunctionTest Cleanliness Bacterial swab test after processing Binding materials Can withstand pulling force of high wind speeds or dismantling Assembly # of finished roofs Targets low income and homeless populations Take survey every month and set timeline goals Water collection Amount of water is suitable for sanitation or farming needs Withstand wind and water conditions Survives hurricane weather in Haiti

Roofing: Concepts & Feasibility

Roofing: Benchmarking Fizzy Bottle HutThatch RoofTile Roof Built from bottles Traps less heat, dampens sound of rainwater Bottle designed to bend into tiling for roofs (William Waterhouse & Linda Loakes) (David Saiia, Professor of strategic management and sustainability at Duquesne University) (Donald Thompson, Canadian designer and entrepreneur)

Roofing: Benchmarking Haitian “Gingerbread Houses” Typical Rainwater Catch SystemSolar Water Disinfection Victorian-inspired design that survived in earthquake Design for rainwater collection usually involves gutter and cistern systems Water treated by sunlight for 6+ hours kills pathogens (William Waterhouse & Linda Loakes)(Professor/Researcher Jose Payero)(Swiss group SODIS)

Tubing: Background & Benchmarking  Find a use for the thick cylindrical sections at the top of bottles that are cut- off to make string  Make low-pressure tubing for:  Drainage  low-pressure plumbing applications  Irrigation  Liquid waste removal  Conduit  Lightweight support structures
