packaging options
PACKAGING OPTIONS
  • Visit to Grocery Store to Survey “Typical” Package Sizes of Dry Ingredients
  • Recommendation is to Produce Four Sizes:
    • Large (22-Cup Capacity): Flour, Sugar, etc.
    • Medium (10-Cup Capacity): Confectioner’s Sugar, Baking Soda, etc.
    • Small (2-Cup Capacity): Baking Powder, Yeast, etc.
    • Extra Small (1/2-Cup Capacity): Spices, Seasoning

    • Obtaining Screw with Proper Dimensions
    • Develop Plan for Multiple Mounting Options
  • Anticipated Problems
    • Fabrication of Working Model
    • Testing
