***week 6 report below***
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Fabricated simplified first two prototypes in machine shop using EDM
1 x scale
2x scale (has suture holes in wings)
Have made design without suture holes
Have evaluated testing area and drill press available at sponsor’s location
Accomplishments from Previous Week
Have physical prototypes made from titanium
Have an easy to manufacture design that eliminates need for suture holes
Initial FEA for older design
Flexure Hinge Analysis
Goals for Next Week (list names after each item). Use specific and measurable objectives
Finalize design
Finalize/Analyze simplified prototype
Fabricate scaled version out of metal (titanium), prototype with no suture holes
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
More confident with new design
Easier to manufacture, simpler insertion method
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
Try to make a design that doesn’t need suture holes
Suture holes will take away from the structural integrity
Difficult to make holes on rounded surface
We made a design that doesn’t need suture holes
Risks and Areas of Concern
Tom said he needs to focus on other groups now
Manufacturing is up to us
Dimensioning and scaling of anchor
1.4mm diameter is too small. 2X scale is still competitive.
Product specs of anchors that are posted online may not be accurate.
Assembling another list of questions for our surgical consult
Resources or Information Required but not Available
Cadavers
Porosity size of bone
Type of drilled hole for soft anchors (clearance or smaller hole where they shove in the inserter?)
Will be included in previously mentioned list of questions for surgeon
Schedule
Manufacture new prototype design out of titanium
Test in Sawbones
Budget (list amount spent and amount remaining)
$240 spent
$860 remaining
