4.4.4.4 Section D: Developing design ideas (20 marks)
Students will develop and refine design ideas. This may include, formal and informal 2D/3D drawing including CAD, systems and schematic diagrams, models and schedules. Students will develop at least one model, however marks will be awarded for the suitability of the model(s) and not the quantity produced. Students will also select suitable materials and components communicating their decisions throughout the development process. Students are encouraged to reflect on their developed ideas by looking at their requirements; including how their designs meet the design specification. Part of this work will then feed into the development of a manufacturing specification providing sufficient accurate information for third party manufacture, using a range of appropriate methods, such as measured drawings, control programs, circuit diagrams, patterns, cutting or parts lists.
Reminder: Analysis and evaluation should be an ongoing process of reflection and iteration.

UTILISING CAD IN YOUR PROJECT
UTILISING CAD IN YOUR PROJECT
There is no absolute requirements that CAD or CAM must be used in your NEA. However, using 3D modelling software provides many opportunities for development, increased quality and modelling.
Additionally, using 3D design software can actually save you a lot of time in the long run as once you gave a completed design, parts lists, assembly drawings and dimensioned drawings that would take a long time to produce by hand, can all be created in minutes.
Read through the slides presentation opposite to better understand how CAD can help you and your design process when completing your NEA.

TECHNICAL & WORKING DRAWINGS
TECHNICAL & WORKING DRAWINGS
As part of section D and the ‘manufacturing specification’ you must create technical drawings suitable enough for a third party to be able to manufacture your product.
The above presentation explains what technical and working drawings are and how you might create and present them in your portfolio.

CREATING & PRESENTING A FINAL DESIGN
CREATING & PRESENTING A FINAL DESIGN
As part of your manufacturing specification you will need a final design that presents and demonstrates your design of what should be the final solution to your problem.
The above presentation explains and demonstrates ways in which you might want to create your final design idea(s)
You should choose materials for your prototype based on their suitability for your project and the specific requirements required of them. For example, if your prototype will be used outdoors, it may need to withstand weather. Or, if your product is load bearing, it will likely need a material with high tensile or compressive strength.
The slides opposite walk you through what to include in your materials choices page and why. With suggested and example layouts.
The final page(s) of section B include a plan of manufacture in which you set out how your prototype will be made and what will be done in which order.
There are a number of ways in which you could produce your production plan from tables and flowcharts to GANTT charts. Below, is an example of how you might use and layout a table, adding new rows as needed. Providing all required information is included, it does not matter which method of planning you use.
The slides opposite will take you through what should be included in your production plan and how it could be presented.
Remember: You are allowed up to 16 hours only for product manufacture
ONGOING RESEARCH
ONGOING RESEARCH
Additional research: understanding hose mechanisms to implement into own design
It is important to continue researching and investigating throughout your design project and the design development stages are an example of where this can be used and evidenced. When developing your design, you may uncover an unforeseen error or hurdle that requires further investigation. Evidence is and explain how it has been used.
Example:
Opposite you can see an example of additional research. In this case, the student required a deeper understanding of trigger mechanisms in hose systems in order to develop the internal mechanisms of her own product so she took apart and existing product to find out how this usually works and also uncovered additional features not thought of such as locking mechanisms and ergonomic grips.
Example 2:
You may be designing something that needs to meet specific human sizes or shapes. In this instance, you could research further (primary and secondary) into anthropometrics and ergonomics and then evidence it in your portfolio, explaining what was found and how it has helped.
FUSION 360 TUTORIALS
FUSION 360 TUTORIALS
Fusion 360 is a fantastically useful tool for designing, modelling and presenting your work. However, there is a learning curve which is why the resources and tasks below have been created to help you learn and develop your skills.
Open the slideshow linked opposite for access to a number of Fusion 360 video and PDF tutorials made for beginners and intermediate learners. The resources in this slideshow build upon the previous tasks and include instructions on how to create important documents that you'll need to successfully complete your NEA.
