Outline of Design activities Project Management Cost outline of project Charts/Revised Problem Statement Top design features, how to make straightener more efficient as well as user friendly Concept Ideas Talks about different methods of approach to key ideas for the straightener. Ex. Power source, Protection, etc. External Search Activities Goes through historical hair straightener models Benchmarks current models and customer appeal Morphological Chart Visual and ordered representation of the concept ideas Concept Selection Pugh Charts Sketch/CAD drawing 3D Solidworks model of hair straightener How does it work? Explanation how the straightener works on a technical level Concluding Remarks How straightener meets standards

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)

User friendly 2.1 Light weight 2.2 Grip F.1 Retractable plug F.2 Temperature dial C.1 Smaller base 2.3 Wide Hinge 2.4 Large plates 3. Aesthetically pleasing 3.1 Different designs/colors 3.2 Sleek design F.4 Cut side walls and tread 4. Environmentally Friendly 4.1 Safe Plastic 4.2 Conserves energy C. 3 Retails under $100

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.

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
