What am I expected to submit in my project folder?

There are certain tasks which are expected to be completed. These are listed below (words underlined are hyperlinks to help pages):

Analysis of the design brief.
Research into speakers / amplifiers and how they work.
Research into existing products.
Product analysis / Product 'teardown' (disassembly and analysis).
Research into suitable materials.
Research into suitable manufacturing processes.
Design specification. Note - you will also need your phone dimensions for this.
4 x Initial design ideas.
Evaluation of design ideas against specification.
CAD development.
Orthographic drawing of final design with full dimensions.
Isometric drawing of final design with annotation.

Optional templates for Unit 1 assignment

You are free to present your work in your own manner, as long as it is your best work. If you prefer to be guided and to use templates, there are a number available for you below.

The folder below contains the assignment brief and the digital files for the Stereo Amplifier case which you will use to help determine the important dimensions. You will be able to upload the 3D model below to your own Fusion 360 account and design your own front panel to ensure that it fits the 'real-world' product that you will be manufacturing in Unit 2 (9792).

Product Disassembly Support

Examples of different products being disassembled and how to explain what has been discovered/what can be used and applied in our own designs.
