A Special Word of Thanks to Our Judges

It is my pleasure to offer a personal welcome to the judges of the Colorado School of Mines
Capstone Design@Mines Spring 2019 Design Showcase. We appreciate your willingness to take
time from your normal activities to evaluate our seniors’ capstone design projects. The
opportunity for our students to get feedback from experienced engineers is invaluable.

The Capstone Senior Design program allows our students to demonstrate the engineering
knowledge that they have acquired throughout their undergraduate course of study, and to do
so in a multi-disciplinary design environment. We encourage you to spend time with the design
teams and to inquire about their projects and their designs. But also ask about their design
process, because in the final analysis, capstone design is as much about learning the process of
design in a team environment as it is about creating a design. As these students enter the
workforce, it is their ability to use design thinking methodologies that they have learned that will
serve them most in their careers.

We are proud of our students and their accomplishments and hope you are equally impressed.
If you would like to get more involved in our program, we are always in search of more project
sponsors. Let us know!

Again, thank you and Happy Judging!

BECOMING A SPONSOR
The Capstone Design@Mines Program pushes students to go beyond their classroom training
and solve real-world design problems. Every semester the program coordinates more than 60
project sponsors and student design teams with meaningful design challenges, spanning a two-
semester sequence that can start in either the fall semester or the spring semester.

What opportunities does your organization have that could be addressed by a motivated student
team?

 SPONSORSHIP FEE        Corporate project sponsors pay a sponsorship fee, of which up to half
                        is made available to the student team for purchasing materials or other
                        project expenses. The remainder supports program facilities, staff, and
                        overhead. Government agencies, NGOs, and other community groups
                        pay a significantly reduced fee and any project material costs.

 TIME COMMITMENT        The involvement of the project sponsor is a key factor in the success of
                        the project. Great project sponsors will commit approximately one-
                        hour every other week to support the student team and ensure a touch
                        point with the team (face-to-face meeting, Zoom or Skype call, etc.) In
                        addition, we also welcome any training or on-site resources that you
                        can make available to the students.

SCORING
We seek to achieve consistency in project evaluations between judges. With that in mind, the Capstone
Design faculty have developed the scoring ballot to aid your judging. Each evaluation category includes
prompting descriptions to guide the evaluation process. To evaluate a team, please select one of the
descriptive words for each evaluation criteria. Scores are automatically tallied within the balloting system;
you do not need to provide a numeric assessment.

                                       which get fed to the power amplification system. This system amplifies the
   Sponsor:                            signal using MOSFETs and transformers; it connects it to the patient using
   Craig Hospital                      standard leads. The housing is designed to keep users from accessing
                                       dangerous circuitry while maintaining functionality. Safety, one of the most
                                       important subsystems, has system-wide integration. There are triggers in the
                                       controls to shut down the device if an input signal is not in a specified range
                                       as well as diodes in the circuit to cut off the signal from the patient if power
                                       exceeds limitations. Extensive testing was completed on substitute skin
                                       models using laboratory equipment; this allowed for multiple iterations of
                                       the device until a desirable outcome was reached.

The 5/8” perforations are common on any industrial welding table for making
jigs and using standard clamps, but the heavy-duty features catered to
facilitating accessibility are completely unique to this design. This welding

This design has combined several materials in order to create a cover that             Dr. Joel Bach
performs equal to or better than a non-prosthetic leg in impact testing. The
final product has been designed to be thin and lightweight as to not impose on         Sponsor:

overarching goal of this project is to allow the design to be used in any
competitive contact sport. Since the top portion of transfemoral prosthetics
vary greatly in size and shape, another portion of this project involves making
a more universal design through a modified girdle. This will allow anyone to
put on a girdle for upper leg protection and still be able to use a one-size-fits-
most cover for the lower leg region.

   Dr. Chelsea Salinas                 with the intent to make the sport more accessible. Most handcycle grips are
                                       metal rods with limited size and cover options, which tend to be
   Sponsor:                            uncomfortable for first time users. Our inspiration came from the belief that,
   HCDS and QL+                        much like how able-bodied cyclists need shoes that fit for a comfortable ride,
                                       handcyclists should have the option to use a grip that is fitted to them. To
                                       accomplish this goal, we decided to create a customizable set of handgrips
                                       that can be easily adjusted to fit any rider and are more comfortable for long
                                       distance use. Our design incorporates the hand’s natural grip and allows the
                                       user to change the grip’s size to fit their need. The grips were tested on
                                       handcycles with experienced users to ensure the grips met their needs.

presented this project to the team at the beginning of the fall semester. In the     Blake Parker (Graduated)

rocks. Two BOEC employees propel the rickshaw, rather than one, to allow for
easy operation, and it is small enough and lightweight to allow for easy             Sponsor:
transport in a pickup truck. Additionally, the device employs a dead man             Breckenridge Outdoor
brake, so the employees do not need to constantly hold it steady on slight           Education Center (BOEC)
hills. Ultimately, the team feels the Backcountry Rickshaw succeeds as a safe,
easy to use alternative to a wheelchair for rough and uneven terrain.

often followed by a sewer smell. The second was to design an outdoor               Laurel Sherman
learning park that would be both fun and informative for the students at           Heather Tat

determined the sewer smell was the result of microbial processes                   (Mapleton School District)
underground, that flourish occasionally under optimal conditions, such as
warm weather and heavy rainfall.
