Summary of Presentation

Key Design Requirements

1. Must be light enough for Gregory to lift (less than 10 pounds, as that’s what’s comfortable for Gregory) and grasp

2. Easy to use with one arm

3. Easy for Gregory to clean and reuse

4. Can be used in hot and cold liquids

5. Can be used for mugs that are 3-4” wide and 3.5-5” high

6. Can be used for pots that are 8-10” wide and 5-7” high

7. Size of the device should be no larger than 8 in x 8 in x 10 in

How it Works

• The weight on the bottom keeps the bobber from always floating to the top

• When the line connecting the bobber and weight is loose the bobber will lay sideways

• When the line connecting the bobber and weight is taught the bobber will float upright

• As the water level rises the line will get closer to being taught which would make the bobber flip upright when the desired level is reached

• This flip from 2 vibrant colors to one will notify Gregory to stop filling the cup or pot

• The product will be cleaned like any other utensil and then it can be reused

Materials

• Slip bobber

• Stainless steel weight

• String/fishing line to attach weight to bobber

User Testing Result

• Gregory was able to determine when the bobber was sideways and showed 2 colors versus when it was straight and showed only 1 color

• His pots are mostly stainless steel or aluminum

• Recommended using a stainless steel or aluminum piece as a weight for the device that will be at the bottom of the pot
