The document summarizes proposed improvements to a trash can prototype based on issues identified with the first prototype. It outlines plans to reduce weight by using thinner materials, improve ease of use with a longer pedal for more force and easier bag changes, and enhance quality. Manufacturing time was reduced by an hour while keeping costs the same. A second physical prototype will be compared to the original CAD model to ensure dimensions and functions match as intended.

1. Project Second Prototype
SATO Group

2. Provide the problems that need to be solved
based on the first prototype.

3. • Trash is heavy. it use pedal
force the very heavy
• Trash does not close
completely to make the
smelly
• The smaller pedal. The pedal
hard.

4. Improve the
following aspects
of your products

5. Quality
• We think there are better quality than
a week ago.
Weight
• Reduce the size of the trash. by
changing the type of plywood to be
thin the parts on the side area of the
trash to be weigh less.

6. Ease of use
• The pedal to be longer and more
will cause force in the pedal
down.
• Therefore ,trash broader and
change black bag can change
easily.

7. Manufacturing time
• Take the time to do just 3 hours
30 minutes from 4 hours 30
minutes.
Manufacturing cost
• The manufacturing cost is same as
last week

8. Compare the second prototype with
the CAD model
• We use prototype
dimension and
function are the
same

9. Thank you
for your
attention
