Design Embodiment

Initial Design Embodiment

You need to sketch the detail parts of the device.

​

The sketch should include the initial dimensions.

​

Along the detail part sketch, Bill of Material should (BOM) be produced.

Finalization of the dimensions

The dimensions proposed in the initial design embodiment stage need to be verified. The verifications of the dimensions will ensure

​

  1. The dimensions are ergonomic based on the anthropometric data
  2. The integrity of the device when the load applies (required engineering analysis: SEMM 4533)

​

​

After the dimension is finalized, CAD model can be built. However, due to the parametric modelling of the CAD model, the CAD model can be built after the initial design embodiment.

The purpose of the CAD model

​

  • To verify the dimensions of the parts when they are assembled
  • To verify the movement of parts without any collision
  • To generate engineering drawing as the final documentation of the design.

Engineering Judgement

Reduce the possible of creating bending force (moment) on the parts

​

  • Avoid abrupt change in dimensions
  • Short force flow.
  • Symmetrical load
  • Balanced distributed load
  • Minimal Curve object

Project: task

Task:

  1. As a group, you have to SKETCH the initial design embodiment including BOM
  2. Assign each person to model the part in Solidworks for part files and as a group for assembly files
  3. Each person has to decide the dimension on the device to be verified. The verification can be done using manual method or features in CAD
  4. Finalize the dimensions in the Solidworks files
  5. Produce part drawing and assembly drawing
