Shake and Bake:

Preliminary Design Report

October 12, 2011

7. Means of Keeping Ingredients Airtight – Submerge each sealed container in water for 10 s. Pass

if all containers are able to keep out water.

8. Time to Detach Containers – Three people who have read the user manual (not members of the

Shake and Bake team) will detach all six containers from the device while being timed with a

stopwatch. Users will then complete a survey about the understandability of the user manual

and ease of use of the device. Pass if all three users complete the task in 60 seconds or less and

select “agree” or “strongly agree” on the survey.

9. Composition of Containers – Pass if material used in containers is on FDA list of approved

materials. If material from 3D printer is used in prototype, state in documentation that

production units will be made of an FDA-approved material.

10. Noise Level – Measure the noise level (in dB) at a distance of 1 m from the device with a noise

level meter. Pass if level is ≤ 90 dB.

11. Program Output – Pass if the device contains a component with visual output.

12. User Input and Measurement Accuracy – Input a measurement of 10 g of flour.

a. For flour, white sugar, brown sugar – Input a measurement of 10 g of flour. Dispense

flour and weigh with a scale capable of measuring to the 0.5 g. Repeat experiment with

measurements of 10 g, 50 g, 100g, and 150 g for each ingredient. Pass if all amounts are

within 5% of the inputted amounts.

b. For salt, baking soda, baking powder – Input a measurement of 5 g of salt. Dispense

flour and weigh with a digital scale capable of measuring to the 0.5 g. Repeat

experiment with measurements of 5 g, 10 g, 25g, and 50 g for each ingredient. Pass if all

amounts are within 5% of the inputted amounts.
