What is a Keloid?Keloids are overgrowths of fibrous tissue or

scars that can occur after an injury to the skin. These heavy scars are also called hypertrophic scars. In individuals prone to keloids, even minor traumas to the skin, such as ear piercing, can cause keloids. The word "keloid" itself comes from the Greek word for a crab's claw; it was first used by a French physician to describe the way that keloids grow sideways into normal skin.

Problem• There is a pressure earring out called “The

Delassco”that is designed to keep keloid reoccurrence down.

• The main problem is that it does not work like the way the designers say it does and doctors do not prescribe it to their patients anymore.

PlanTo design a pressure earring

through rapid prototyping that will better suit the

patients needs after keloid removal.

What is Rapid Prototyping?

The creation of a working model of a software module to

demonstrate the feasibility of the function. The prototype is later refined for inclusion in a

final product.

Procedures Design CATIA file Build product through rapid prototyping Examine prior research Formulate questionnaire Contact participants Send participants questionnaire Form “House of Quality” chart Receive results and insert results in chart Make conclusion based off results

What is Quality Function Deployment?

Quality Function Deployment is also known as QFD. Which is a “method to transform user demands into design quality, to arrange in a position of the functions forming quality, and to arrange methods for achieving the

design quality into subsystems and component parts, and ultimately to specify

elements of the manufacturing process.

What is House of Quality?

• Voice of the customer

• Product Features

• Competitive Analysis

• Correlations

• Technical Evaluation

• Trade-offs

Questionnaire• Is attractiveness important?• Is weight important?• Is comfort important?• Is maintaining the pressure on the ear important?• Is cost important?• Is “easy assembly” important?• Is durability important?• If there is anything that we have not mentioned that

you find important? Please write it in and rate it.

Results

Conclusion The finished product is more suitable for the

customer’s needs than “Delassco” earring.

• The plans for the earring is, if it suitable and marketable for the society, we plan to sell our product worldwide to help the needs of people that need this treatment.
