Note: Despite this is displayed as a sequential process, dates show that
overlaps and iterations might be necessary for fine tuning the solution and documenting it
Concept Refinement
1. Reconsider the concept which was selected
as the most promising during the 2nd
review meeting
2. Apply/propose the required modification
as highlighted by the company
representative
3. Start planning a general layout for your
solution
• Where will the subsystems be placed?
• How much room do they need?
4. Check for existing components that should
not be produced from scratch and that are
available in the market
• Check for existing 3D models to
import
• Check the toolbox/shop of
components embedded in your CAD
modelling system
Gantt Chart
1. Identify required sub-systems for your
solution
2. Organize your work in tasks and
subtasks
• Sub-systems can be used as a
reference to organize tasks
3. Identify relationships between
subsystems and plan the tasks
accordingly (in time and contents)
4. Define appropriate timeslots for each
task and subtask
5. Allocate sufficient human resources to
carry out each of your tasks
• Define responsibilities
• Define required inputs
• Define expected outputs
Parts and Assembly Modelling
1. Share ideas with your team mates about the
software to use and find an agreement
2. Define, if needed, an adequate file format for
file exchange among team members
• If your group uses SolidWorks and Catia,
it is easy to share part files between
software and also across versions of the
same software by means of .3dxml file
format to limit feature losses
3. Start modelling parts as stated in Gantt
Chart (refer to prof. Grafinger’s lecture for
modelling guidelines)
4. Mate parts and create sub-assemblies
according to the Gantt Chart
5. Mate sub-assemblies and make a complete
3D model of your solution
(Mechanical) Behaviour Assessment
1. Identify moving and static parts
2. Double check the consistency of
mutual relationships
between/among parts and
subassemblies with the expected
analysis you want to run
3. Identify working conditions you
would like to simulate, for
instance:
• Constraints
• Loads
• Movements
• Maximum or minimum room
required
• …
4. Refer to prof. Grafinger’s lecture
for simulation guidelinesConsolidation and Documentation
1. Finalize the complete 3D model of
your solution by fixing what was not
satisfactory after the assessment
2. Define a structure for your report
3. Include in your report some crucial
factors to evaluate the goodness of
your solution:
• Manufacturing costs
• Potential sale prices
• Potentially evaluated differences
between Make OR Buy
approaches
4. Attach relevant files to your report
• 3D models
• Bill of Materials (BOM)
• Renders (if any)
