04_Class Notes: Tues. (event date: 1/9/15)
Due Thursday:
- 1st ENGR Notebook
- Quiz 3 Chapter 5
Topic Selection:
- Project Topic: short phrase that describes your planned prototype
- Problems: your product will solve
- Project Description: full paragraph(s) depicting overall function(s) of device and technological scope
- Benefits: benefits for intended users
- Decision Matrix: 3 or more project finalists with decision summary
- Team Members and designated leader: submit one MS Word document to Canvas
Senior Design Rule #2: have a passion for your design project
Decision Matrix:
(1) Determine the selection criteria
(2) Determine criteria weights
(a) percentage = relative importance
(b) ensure total of all weights
(3) Identify reasonable alternatives
(4) Rate alternatives relative to the criteria
(a) recommend 1,5,9 (good,better,best)
(b) never use more than 5 levels
(5) Compute scores for alternatives
(6) Evaluate and review decision
(a) usually reject several alternatives
(b) if 2+ alternatives look feasible
(i) review eights and re-score
(ii) multiply scores rather than add
(iii) determine additional realistic criteria to help discriminate
Recommended Criteria:
class requirements
Group Thoughts:
After discussing Physical Therapy tour, the finger tensioner forearm-device seemed to be preferred project trajectory.
Hand plant/weight shift device
Finger tensioner/extender; forearm equivalent:
discussed more extensively, included as a possible project topic due to feasibility and inclusion of electrical and mechanical components
Shoulder assist:
discarded as project topic due to the problem of overcomplicating the device with electronics when mechanical systems may be better for this application
Scoliosis back support/breathing ability:
Leg splint with on/off capability:
Sit-to-stand back corrector: not leaning forward far enough: "nose-to-toes":
discarded due to complicated nature of gait and human locomotion (lots of research would need to be done studying how device would affect other aspects of sit-to-stand locomotion other than simply the "nose-to-toes" movement
Weight assisted treadmill:
added as project topic possibility because of good BME/EE field inclusion and feasibility
Sterilization solar-clave:
added as potential project topic for feasibility & BME/EE inclusion but not as preferred due to smaller innovation aspect
Prosthetic arm: hand replacement, attaches to forearm
added as potential project topic
To finish up our in-class meeting we decided on the criteria points for our project topic selection matrix.
