Assignment criteria

Introduction

One of the main challenges for Designers in today’s technological environment is that of communication. The task of generating and communicating design ideas can help develop a product or convey a solution to a problem. There are many methods to demonstrate your products or ideas; this assignment is designed to allow you to show these methods and understand the importance of design development. In order to produce feasible design solutions a designer must have an understanding of manufacturing processes, economic limitations, material finishing processes and assembly methods.

Assessment criteria

The three Questions required for your submission in one portfolio are as follows.

Question 1

A heritage motorcycle parts supplier specialises in and manufactures parts that are no longer available. There are no drawings and casting moulds are no longer in existence. They have asked you to investigate the possibility of remanufacturing replica Cylinder heads as new, using existing parts as reference material for size and form. 3D scanning and Reverse engineering in CAD software would be a starting point from which a decision could be made as to the most suitable manufacturing method. Parts would fit into a 250 x 250 mm cube and weigh between 1.5 and 2kg.

• Outline a suitable 3D laser scanning setup/process to extract data to facilitate remodelling.

• Present a range of manufacturing options that may suit both Ferrous and Non-Ferrous cylinder heads.

Use referenced sources for your information, feel free to include images to summarise processes with graphical data to support your justification. Suitability of process (and summary) to the material, Surface finish, additional operations, tolerances, time to manufacture and costs can also be included.

(Assume that the initial demand would be niche, so 50 units per annum. Would the process change if 2000 parts per annum were required? Support with data to show how batch costs vary.

A brief introduction to the whole assignment would be good, but no need for an Abstract. 25%

Question 2

Describe three methods of coating materials. Include details on the suitability for different materials, whether it is decorative or functional, advantages. Feel free to outline the application process, limitations, example products and alternatives. Use images and examples to support.

NB. This is not linked to part 1 above. (Guideline 2 pages) 15%

Question 3

Design: You are to choose a handheld product or device from the Table 2 below, or a similar product related to your job role. For the chosen item you are to carry out a design process with research with images and brief analysis of existing products with a view to improve through a modification and/or addition. You could include some user data in your research to support ergonomic design. You will develop possible solution sketches, a chosen concept and CAD model. The design you choose needs to be modelled with features linked to the design using sketching and 3D CAD representation. Creating a render view, engineering drawings will enhance your submission. Try to make separate parts to help convey how the product may function.

Multimeter

Audio visual controller

Data logger

• • 3D CAD model demonstrating efficient use of CAD features and clear Design Intent. Annotate/describe your design intent and product features. (guideline 2 pages) You must insert screenshots of your design. You may also include 2D Orthographic Engineering Drawings from your 3D CAD model to enhance the communication. You must also submit your Final CAD data, or online share link for assessment. 35% 100%

Academic Dishonesty applied to all sections

All work submitted must be your own work and all sources must be properly referenced and cross referenced to the relevant parts in the report as per the university guidelines.

We expect you to demonstrate learning by completing your assessments yourself in your own words.

Can I use AI tools at University? Answer

AI tools can be useful in supporting your learning and writing at University, but you need to be clear on how and when they should be used to avoid accusations of academic misconduct.
