Initial research

1. Analyze Art's symptoms to determine the diagnosis
2. Initial model design formulation
3. Identify need statements by reading profile </aside>

Design Decision

Diagnosis — hip dysplasia

<aside> 📖

We researched similar symptoms online and identified possible diagnosis. I proposed that the issue was related to bone damage caused by friction due to dislocation and improper bone development. We discussed the symptoms and information provided in the patient profile as a group. Later, I confirmed my idea with a doctor and it became the basis for our final diagnosis of hip dysplasia.

<aside> 💡

Hip dysplasia means the hip is not stable and causing pain due to friction caused by dislocation (Figure 2).

Total hip replacement surgery can be an efficiency treatments.

Material

<aside> 📖

• We analyzed several materials and discussed their advantages and disadvantages based on mechanical properties.
• I preferred Zr-2.5Nb which suggested by a group member, due to its good biocompatibility and high corrosion resistance.
• I did more research on Zr2.5Nb, focusing on its mechanical properties such as strength and elastic modulus </aside>

Draft Model

<aside> 📖

I drew a draft design for the appliance and shared it with the group. We discussed together, focusing on the advantages, and combined strengths of each proposed design. We drawing an initial design on the board as the basis for further development. Later, I modified some inappropriate design elements such as the cap which is the brown part showing in the picture (Figure 3).
