Take a clear photo of the overall prototype and upload it.

Capture close-up images of how parts are joined (screws, glue, hinges, etc.).

Write down your observations.

• How are the parts joined together? (e.g., screws, bolts & nuts, glue, etc.)

• Why are they joined this way? Flexibility – Does the joint need to allow movement?

• Material compatibility – Does the method work well with the materials used?

  Eg. Some materials do not bond well with glue (e.g., wood and acrylic may require screws instead of glue because acrylic does not absorb adhesives well).

• Suggest another method to join the parts, if any.
