PROJECT MANAGEMENT The total amount of the hair straightener parts (Chi) $70
The motherboard and switch were the most expensive ($50 dollars)
The plastic covering costs $5
The metal wires and aluminum and ceramic plates $15
We reduced costs by using recyclable plastic (polylactic acid polymers that cost ($0.90-$1.00)

REVISED PROBLEM STATEMENT Redesign a hair straightener that would be more environmentally friendly, cost
effective, aesthetically pleasing, and above all safe for the consumer to use. We learned that 54 % of customers received at least one burn injury from their
straightener a week. In order to fix this problem, we plan to implement an insulating system near the
ceramic plates to prevent consumers from getting burned. It was found that 70 % of users were not completely satisfied with design of their
straightener and rated their straightener’s design below a “5.” It was found 66 % did not have an automatic shutoff feature, and people taking the
survey said they straighten their hair at 300 degrees Fahrenheit or higher. To help the straightener be the safest it can possibly be, we plan to install a
automatic shutoff feature on our straightener. Environmentally-friendly and cost efficient plastic to ensure corporate responsibility,
as well as reduce cost, in order to give our product a competitive advantage on the market.

SOLIDWORKS SKETCH (FINAL DESIGN)
HOW DOES IT WORK? Plugged into the wall to receive electrical
energy. Once the straightener is has the Energy runs through the wires to the aluminum
conducting plates. The conducting plates then heat up the ceramic
plates which are able to retain the heat. Once the ceramic plates are heated the
straightener is ready to use. Then the straightener clamps the hair and
straighteners it
