Answer 6

Identifying the customer and the problem, Stage 1,
In concept and ideas, Stage 2, sketching may be used to clarify a possible solution to a problem.
In compromise solutions, Stage 3, sketches are used to analyze preliminary design with design layout.
In developing models, Stage 4, dimensioned sketches are sometimes used to create prototypes.
In engineering designs, Stage 5, sketches are used to create the detail drawings.

Question 10

Describe the differences between the traditional design process and the concurrent design process.

Answer 10

The concurrent design process usually happens in a shorter time frame then the traditional design process.
The traditional design process relies on sketches while the concurrent design process relies on CAD
Traditional design and manufacturing activities happen in sequence where concurrent design happens in simultaneous activities.
The traditional design process would not catch manufacturing concerns until the end where as the concurrent design process integrates manufacturing with the design process.
