Short Title:Design 1
Full Title:Design 1
Module Code:DESI H2001
 
NFQ Level:6
 
ECTS Credits:5
Reviewed By:FIONA CRANLEY
Description:Design 1 will provide the student with experience of the general engineering design process, and provide a foundation for Design 2. Students will be equipped with the knowledge to apply solid modelling techniques to assist the design and development of typical engineering components. Students will apply concurrent engineering assembly techniques for working effectively in teams and enable them to contribute to the modification or design of manufacturing systems and products.
Learning Outcomes:
On successful completion of this module the learner will be able to
  1. Produce 3D CAD models using industry standard solid modelling software.
  2. Compare and use visualisation techniques such as wire frame and solid modelling.
  3. Compare parametric and variational design techniques.
  4. Explain the underlying concepts of concurrent engineering.
  5. Construct and orientate part datum features such as datum planes, datum axes, and datum points.
  6. Produce a dimensioned 2-D orthographic and isometric drawing from a 3-D model.
  7. Create assembly hierarchies, and apply appropriate assembly constraints.
  8. Generate general assembly drawings with bills of materials.
  9. Describe various methods of exchanging CAD data between different systems.
  10. Export design data for construction of rapid prototype models such as selective laser sintering (SLS).
