Milestones Summary

1. Team Development and Project Planning

   • Assigned team roles and responsibilities for the next four weeks of the project
      

2. Patient Diagnosis and Need Statement

   • Give a patient profile (Name: Ke Huy-Quan), researched and documented pertinent information from online sources and invited guests (including orthopaedic surgeons and radiologists) in order to determine an appropriate diagnosis

   • Defined a solution-neutral need statement for our client​

   • Listed objectives and constraints of our design
      

3. Conceptual Design

   • Generated a preliminary sketch of a solution to address the need statement​​

     • Conducted research on form and surgical fixation of implant when generating design​

   • Shared preliminary sketches with team

     • Suggested design revisions for all other designs​

   • Created one refined concept solution for further development

     • Discussed advantages and disadvantages of design with reference to need statement
        

4. Preliminary Design (3D CAD Design)

   • Created a solid model of a femoral stem for a hip replacement

     • Form and dimensions based on a given 3D printed model

   • Refine the 3D printed design

     • Additional features (e.g. surface textures, rounded edges) added as seen fit to improve the design​
        

5. Preliminary Design (Mathematical Analysis)​​

   • Calculated fracture risk, fatigue life, and bone stress reduction of a hypothetical implant

     • Used fourth-year level bone mechanics formulae

     • Interpreted given materials data sheets
        

6. Materials Selection and Justification​​​

   • Researched three candidate materials for two components of the implant​

     • Analyzed materials' structure, properties, and processing from research articles and materials data sheets

   • Chose one candidate material per implant component and justified decision based on conducted research and relevance to assigned patient​
