Identify  the  Problem  

A  device  is  needed  that  would  allow  a  person  with  rheumatoid  arthritis  to  open  jars  with  different  size  lids  

Example:

Develop  a  Design  Brief  

Identify  Criteria  and  Constraints  What  exactly  should  the  device  do?  

What  should  it  not  do?

Gather  Information  

Use  a  KWL  chart  What  information  must  we  locate?  

Perform  the  research

Brainstorm  Alternative  Ideas  

All  ideas  are  ok  This  begins  the  creative  part  

Any  format  is  ok.    (words,  sketches)

Decide  on  the  Final  Design  

Narrow  down  the  possibilities  Decide  on  the  best  idea  

Justify  the  idea

Build  the  Prototype  

Follow  your  plans  &  drawings  Revise  if  necessary  during  prototyping

Test  and  Evaluate  

Does  it  work  as  anticipated?  Does  it  meet  all  criteria  and  constraints?

Redesign  or  Refine  

If  it  works,  improve  it.  If  it  doesn’t  work,  redesign  it.  

What  went  wrong?    How  can  we  fix  the  problem?
