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.

Intermediate  Designs  

Characteristics  of  final  design:  

• Food  Safe  • Durable  • Economical  • Space  Efficient  • Cake  pops  easily  accessible

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.

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.
