ENME 472 Engineering Capstone
Mechanical Design Engineer
Project Goal: Develop a product capable of heating a bicycle seat
Result: Conducted market research, designed conceptual solutions, and built functional prototypes to validate solution
Market Research
• Interviewed individuals in our target market to gauge interest in product, and to gather key consumer and engineering requirements for our solution.
• Explored relevant patents, examining both potential competitors as well as potential business partners
Conceptual Design
• Conducted brainstorming sessions where market research was used to help ideate various solutions.
• Both electro-‐mechanical and strictly mechanical designs were explored. A strictly mechanical design was ultimately chosen, as it best met customer requirements.
CAD Drawing and Work-‐Like Prototype
• Developed CAD drawings to be referenced while building our prototype.
• Constructed a functional prototype which was used to validate our solution.

Baked By Yael Packaging Design Consultant
Project Goal: Develop a packaging solution that will deliver cakepops to customers in an aesthetically pleasing, safe, cost-‐effective, and timely manner.
Result: Implemented the following strategy to develop packaging solution:
Strategic Planning
• Generated list of desirable characteristics in our packaging design, and organized them from “must have” to “would like”.
• Created a strategy canvas to compare our proposed solution (plastic inserts) to other solutions currently available.
2D Sketching
• Created preliminary drawings and organized them based on the design of the insert and how each would look in different bakery boxes.

Functional Prototype
Rapid Prototyping
• Used 3D Printing to create a plastic model of our final design.
• This 3D print was then used as our mold during vacuum forming.
Vacuum Forming
• Assembled our own vacuum forming machine (left).
• Used food safe PETS plastic to create a full-‐scale replica of our recommended insert (right).
Final Packaging Recommendation
Stock Boxes • Increased durability by ensuring the plastic inserts fit snuggly inside the bakery box.

Varroa Mite Knocker
Project Goal: Further develop a beehive knocker designed to agitate the colony in an effort to cause deadly mites to fall from the beehive.
Result: Original Prototype (left) vs. Improved Design (right)
Improvements: 1. Reduced overall size by 50% by repositioning the
Arduino and circuit board. 2. Increased knocker strength by 200% by moving springs
from in front of the plunger to behind the plunger. 3. Facilitated attachment of the knocker to the beehive by
using permanent wings. 4. Utilized WakeUpOnStandBy Program to increase
operating time of knocker . 5. Protected the interior electrical components by creating
a 3D printed weather proof housing.

IDEO.org Human Centered Design for Social Innovation Challenge
Credit Card Add-‐on
Course Goal: Use concepts of Human Centered Design to help students save money.
Result: Developed a credit card add-‐on that makes students more aware of how much money they are spending.
Human Centered Design
Hear
• Developed interactive activity to identify why students spend beyond their means. • Results showed that because majority of purchases are performed with credit cards,
students don’t see the immediate implications of their spending habits.
Create
• Developed 3D model of potential solution.
• Created physical mockup to show what the product would look like.
Deliver
• Gained feedback from target market on opportunities for design improvements. • Identified future steps to create a proof of concept prototype. • Identified ways to monetize our product.
Human Centered Design 7
QUEST Projects Course Goals: Develop innovative solutions for a new product and system.
Result: Utilized various quality tools to develop conceptual solutions shown below:
Conceptual Design for CHARGe-‐
• Developed the preliminary designs for a portable charging device capable of charging both laptops and cell phones simultaneously.
Systems Design for Recycling Rewards
• Performed market research activities to identify ways we could encourage students to recycle more frequently. Results showed that incentivizing students with discounted food, parking, and Maryland apparel would be a viable option.
• Created a conceptual design for a new app that would communicate with recycling bins in order to track users’ recycling and reward them accordingly.

ENES 100 Introduction to Engineering Design (Hovercraft Project)
Electromechanical Design
Course Goal: Build an autonomous hovercraft designed to navigate a course, pick up a payload, and then exit the course.
Result: I designed a unique electro-‐mechanical feature that would designate when the payload has been acquired:
• Prior to payload acquisition (top), electrical wires are latched together ensuring a closed circuit.
• After payload acquisition (bottom), an open circuit was created. The Arduino then informed the hovercraft to lift the arms using a servo motor and proceed to exit the course.
