CRITERION E CONTENTS LIST
WHAT MAKES FOR A SUCCESSFUL CRITERION E?
Commercial changes are clearly based on research (primary & secondary)
Design changes are made and justified using research
Technical drawings can be read and understood by professionals
Clear consideration for commercial production by designing moulds and jigs etc
Bill of materials is clearly linked to research and accurate
Evidence of consideration for scale of production and the impact of material and machine costs
The guidance in the slides opposite includes Fusion 360 video tutorials that explain how to create mould for injection moulding, jigs, exploded views and dimensioned parts drawings.
- IDENTIFY REQUIRED CHANGES
Small table format
Lists 'Part', 'Commercial Change' and 'Justification'
2. COMMERCIAL REDESIGN
CAD developments to the design to include identified changes
Varied angles, views and close ups used to show changes
Design for moulds and jigs where necessary
Basic annotations used to identify, support and explain commercial changes
Final render of your final design in isometric view
One or to alternate view and/or close ups to help explain the design
Refer to proposed scale of production
Basic annotations to support and explain
3. COMMERCIAL PARTS LIST
Isometric, orthographic or exploded view of design
Parts are identified with numbers and arrows
Each part has a number, name, material and function labelled
4. COMMERCIAL ASSEMBLY DRAWING
Exploded view used in line drawing format
Arrows and annotations explain assembly
Refers to commercial manufacturing
5. COMMERCIAL PARTS DIMENSIONED DRAWINGS
One for each major part
Label each with a part title, scale and your name
All external, internal and adjoining spaces are dimensioned
One for whole product assembled
6. COMMERCIAL TOOLING/MOULD/JIG/ DESIGN
3D Drawing or CAD render shows what it looks like
Annotations to explain features and functions
Exploded view shows how it will fit together
Sectional view shows internal spaces
Annotations to explain features and functions
7. BILL OF COMMERCIAL MATERIALS
All materials used are listed in table format
Material use (which part it will be used for)
Cost per common unit sold
Amount used
Total cost for 1 prototype for each material and total cost overall
Include costs of any required software
Explain scales of purchasing and production and how this can affect cost
