Drexel University's Engineering Design 103
Spring Term 2015
Section 80
Group 9
In this
Engineering 103 Freshman Design Course, the students are tasked with
collaborating, designing, and creating a solution to a wide range of biomedical
engineering problems. The students will be held accountable for thoroughly
researching the problem, formulating a reasonable solution, and then designing
it cooperatively in and outside of the design laboratory. For this particular
laboratory, the students plan to create a new artificial heart valve. The
students chose this particular topic because heart valves are one of the most
valuable devices in the biomedical industry as “[e]very
year, more than 100,000 US patients need to have their dysfunctional or
diseased valves replaced with a prosthetic valve.” (Vesely) Furthermore, the motivation behind this design
project is to propose a new way in which heart valves can be created in order
to minimize difficulties that those in the biomedical engineering industry
face. For example, a current valve can create blood clots and its’ longevity
needs to be improved. In this design course, the students will initially learn
to thoroughly research the necessary background information in order to get a
sense of the problem that they are dealing with, and then later implement that
valuable information into collaboratively designing a solution. The biggest
task will be formulating an idea that is new and different than the heart
valves that are currently used, making sure that it can be practically used,
and lastly creating a tangible prototype of the device. Some technical
challenges that the students will face include: choosing the material that will
be most suitable to go into the human heart and properly sizing the design so
that it can be scaled down 3-dimensionally and be printed accurately. The
desired outcome of this project is to create a working heart valve, but also to
expand the knowledge and engineering skills of all the students that are
involved.
