FOURTH  YEAR  CAPSTONE  PROJECT      

BOOMBARDIER  AEROSPACE  FLEXIBLE  WORK  CENTRE    

PROBLEM  STATEMENT    To  design  and  refurbish  a  new  flexible  work  center  that  is  able  to  assemble  all  different  series  (Global  6000,  7000)  of  aircraft  in  a  single  assembly  line.    DESIGN  STATEMENT    The  purpose  of  this  project  was  to  solve  Bombardier  Aerospace’s  assembly  line  problem.    Bombardier  Aerospace  uses  different  assembly  workstations  and  devices  to  assemble  different  types/series  of  aircrafts,  which  causes  many  troubles  with  time  management  and  availability  of  a  free  assembly  line.  Our  goal  was  to  make  such  work  stations  that  provides  more  flexibility  in  terms  of  accommodating  different  series  of  aircrafts  into  all  assembly  lines  and  provided  more  mobility  around  the  fuselage  without  actually  having  to  move  aircraft’s  position.      RESULT    We  built  a  workstation  with  many  new  features.  The  thought  process  lead  to  the  realization  that  the  two  biggest  changes  that  could  exist  in  a  different  aircraft  would  be  the  width  and  the  height.  So  we  provided  height  adjustment  using  rack  and  pinion  assembly  and  extendable  platforms  to  provide  width  adjustment.    

   

   

     

       

     

SECOND  YEAR  DESIGN  PROJECT  1    

ETCHING  PRESS    

PROBLEM  STATEMENT  To  design  new   small   intaglio   etching  press   on  Autodesk   Inventor   tweaking   the   already  existing  for  better  performance  with  minute  details  provided  by  the  professor.    DESIGN  SOLUTION  I   suggested   to   add   laser   sensors   right   in   the   beginning   of   the   rollers   where   the   sheet  enters  which  detects  the  presence  of  sheet  metal  which  further  leads  to  motorized  rollers  rotating  at  certain  speed  to  deliver  faster  prints.    RESULT  

 

     

SECOND  YEAR  DESIGN  PROJECT  2    

MOTORISED  TROLLEY    

PROBLEM  STATEMENT  To  design   test   and  build  prototype   for   a   trolley   that   can   carry   a   standard   sized  oxygen  cylinder  upstairs  in  hospitals.    DESIGN  SOLUTION  A   conventional   trolley   design   with   a   Tri-­‐Star   wheel   assembly   was   proposed   after   a  number  of   sessions  of  brainstorming.  The  applicability,  practicality  cost  and   the  case  of  building  was  considered  along  with  the  design  being  interactive.  The  team  was  divided  in  3  subgroups  to  make  the  process  more  efficient.    RESULT  The  design  was  awarded  the  second  best  design  among  56  teams.  

 

     

   

   

   

INITIATION  I   joined  McMaster  Solar  Car  Project   in   the  beginning  of   the   third  year.  The   team  at   that  time  as   in  a  process  of  building   the  all  new  car  after   four  years  of  gap.  After  going   into  couple  of  meetings   I  was  asked   to   lead   the   chassis,  which   is   a   sub-­‐group  of  mechanical  team.   First   few   weeks   were   more   like   a   catch   up   time   for   me   knowing   how   to   team  functions  and  what  are  the  expectations  and  deadlines.  There  were  Gantt  chart  meetings  conducted  which  gave  us  a  clear  insight  of  the  tasks  and  the  deadlines.    PROJECTS  The  projects   I  am  entitled   to  work  on  are   typically  based  on   the  chassis  of   the  car.  The  design  that  is  being  used  is  an  alternation  and  revision  of  the  design  used  in  earlier  cars.  My  main  duties  include:  

Ø Analyzing  the  design  of  the  chassis  and  make  amendments.  Ø Work   on   suspension   installation   points   and   positioning   of   the   steering   rack   and  

pinion  column.  Ø Perform  Finite  element  Analysis  (FEA)  Ø Estimate  the  amount  of  metal  required  to  make  the  chassis.  This  includes  working  

with  the  business  and  manufacturing  team..    

 

 

                                                                                                               THIRD  YEAR  DESIGN  PROJECT                                                                                                                                        ROBOWALKER    PROBLEM  STATEMENT  To  design  and  compute  a  project  that  aids  common  man’s  problem  in  the  present  world.    DESIGN  STATEMENT    The  purpose  of   this  device,  called  the  Robowalker,   is   to  assist  people  who  have  trouble  walking,  such  as  paraplegics  or  the  elderly.  The  device  would  be  design  to  assist  people  in  carrying  approximately  60%  of  their  body  weight  to  take  stress  off  of  leg  joints,  muscles  and  bones  by  providing  a  torque  at  the  knee  joint.  Although,  the  control  system  part  was  not  in  the  scope  of  this  project.      RESULT  We   successfully   created   an   AutoCAD   assembly   to   demonstrate   the   full   idea   behind   the  project.
