Engineering Requirements (Metrics & Specifications)

Constraints

Our project is intended to be used by farmers in Borgne, Haiti who have limited resources in general. There are several constraints that have guided our project to its current direction. Some of the constraints involve:

• Resources
  • Materials available in Haiti to build and replace parts are extremely limited. They may include:
    • Nuts & bolts
    • Nails
    • Scrap metal/plastic/wood
    • Simple materials may be able to be purchased in the larger cities (Port-au-Prince)
  • Tools to build with are also very limited and may include:
    • Hammers
    • Screwdrivers
    • Machetes
    • Wrenches
    • Power tools only if a generator is available

• Energy Sources
  • 'Renewable' Sources
    • Wood - not sustainable
    • Charcoal - not sustainable
  • 'Sustainable' and 'Renewable' Sources
    • Methane
    • Solar Energy

• Transportation of Materials
  • Limited to being carried by humans or donkey
  • Walking from town to town can take anywhere from 20 minutes to 6 hours

• Employment Wages
  • Minimum wage for employed Haitians = $6/day for 8 hours per day
  • Skilled laborers = $10-$15/day

All of these constraints limited our potential solutions. Throughout the course of this project we had to keep these constraints in mind. The constraints are reflected in our project feasibility documents in Systems Level Design and Detailed Design.
