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.
Plan
To 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.

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

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.
