MODULE DESCRIPTION
The aim of this module is to give students an opportunity to experience the process
of carrying out design and make project.

It will enable them to appreciate that design involves synthesising parameters which
will affect the design solution.

The module will introduce them to the workshop and a number of manufacturing
process including turning, milling and sheet metal forming.

These elements will allow the student to carry out a design and build project fully
with the aim being to produce a working prototype/ model of the finished product.

LEARNING OUTCOMES
On successful completion of the module, students will be able to:

1. Develop a design specification that establishes customer requirements.

2. Develop and understand a design report with design concept, evaluation of
concepts and selection of optimum design solution.
3. Utilise and use computer technologies in the design process.
4. Employ correct tools, methods and measurement techniques, use them to
construct quality finished engineering products in a safe and efficient manner
and evaluate these engineering products for quality and accuracy.

INDICATIVE CONTENT
A) Design Process:
 Customer requirements: all relevant details of customer requirements
(aesthetics, functions, performance, cost, production parameters) are
identified and listed.
 Design specifications: implications of specification parameters and
resource requirements are identified and matched; the level of risk associated
with each significant parameter is established.
 Design information: all relevant information is extracted from appropriate
reference sources, techniques and technologies used in similar products or
processes are identified, when new technologies can be used, these are
specified, relevant standards and legislation are identified and applied
throughout.
 Design solutions: analysis of possible design solutions: matrix analysis,
brainstorming, mind mapping, forced decision making.
 Evaluation: costs, future development potential, value engineering concepts.
 Compliance check: using check-lists, design review procedures.
 Report: rationale for adopting proposed solution, appropriate techniques and
media in presentation of report.

 REGULATIONS
The module conforms fully to the UG/FD regulatory framework; please refer to the
link below for further details regarding all the university regulations:
https://www.derby.ac.uk/about/academic-regulations

Lectures and Tutorials Guidance: The module will be structured with lecturers and
practical sessions. You will be expected to attend all the lectures and tutorial
sessions.
Risk Assessment: For the classroom based teaching, a Risk Assessment has been
carried out by the University identifying the significant hazards and risks within this
environment. These will be communicated to you by the lecturer / technician during
the first lecture / session.
For workshop and/or laboratory sessions, specific Risk Assessments have been
carried out by the University identifying the significant hazards and risks associated
with specific activities in these environments. These will be communicated to you by
the lecturer at the beginning of the workshop and/or laboratory session.
As a minimum, during all workshop/laboratory sessions, you will be required to wear
protective footwear and appropriate clothing for a workshop environment.
Please speak to the Module Leader/Tutor if you are unsure or if you have any
special requirements that need to be considered in the planning of a
workshop/laboratory session.
Academic Offences: An "academic offence" has been committed when a student
tries to gain improper advantage for her/himself by breaking, or not following, the
Academic Regulations concerning any part of the assessment process. This
procedure applies to all students engaged in any University assessment activity
whether on or off site including collaborative programmes. Students must understand
what constitutes an academic offence including plagiarism, collusion and breach of
examination room regulations, and ensure that they do not commit such offences in
their studies and assessments.
Late Submissions: There are No automatic right to late submission with a capped
mark of 40%. However, the University acknowledges that there may be
circumstances which prevent students from meeting deadlines and there are now
three distinct processes in place to deal with differing student circumstances:
1. Assessed Extended Deadline (AED): Students with disabilities or long term
health issues are entitled to a Support Plan. The Support Plan will outline any
adjustments to assessments which are required to accommodate an
individual student’s needs.
2. Exceptional Extenuating Circumstances (EEC): The EEC policy applies to
situations where serious, unforeseen circumstances prevent the student from
completing the assignment on time or to the normal standard. Students who
submit a successful EEC claim will usually be required to complete a
different assessment to that which was originally set. All EEC claims will be
considered by Faculty/UDC panels, which will convene on a monthly basis.
For further details refer to the link:
3. Late Submission up to One Week: Covering unexpected and severe
disruption to study, where circumstances do not require the additional time
allowed for by an EEC, the Late Submission process enables students to
complete their existing assessment up to one week late, without a cap on the
grade. Requests for late submission will be made to the relevant Subject
Manager in the School who can authorise an extension of up to a maximum
of one week. The Subject Manager will expect to see compelling evidence
that such an extension is appropriate.

Introduction
Engineering Design can be defined as an efficient and effective process that is
concerned with the development of ideas that leads to new products. Engineers
conceptualise and evaluate those ideas, using a systematic approach, making
them tangible through products. Their role is to combine art, science and
technology to create tangible three-dimensional products, facilitated by digital
tools. These tools allow engineers to communicate, visualise and analyse ideas in
a way that would have taken greater manpower in the past. The aim of this module
is to give students an opportunity to experience the process of carrying out a
design and build project. It will enable them to appreciate that design involves
synthesising parameters which will affect the design solution. The module will
introduce them to the workshop and a number of manufacturing process including
turning, milling and fabrication.

These elements will allow the student to carry out a design and build project fully
with the aim being to produce a working prototype/model of the finished product.

Learning Outcomes:
1. Develop a design specification that establishes customer requirements.
2. Develop and understand a design report with design concept, evaluation of
concepts and selection of optimum design solution.
3. Utilise and use computer technologies in the design process.
4. Employ correct tools, methods and measurement techniques, use them to
construct quality finished engineering products in a safe and efficient manner and
evaluate these engineering products for quality and accuracy.

Module Brief
You are required to design/make a Nutcracker and a Plumb Bob please refer to
drawings provided. The products must be manufactured using the resources and
facilities available within the University of Derby Workshop so that it can be tested
and used to provide accurate function. The design should also include a metal
bodied housing case to fit the product inside it.

In the workshop you are required to demonstrate machining skills such as shaping,
fitting, turning and milling. The items should be designed by having the following
questions in mind:

 Can the designed product be made?

 What exactly will each part be made of, how will it be shaped, formed or
joined?
 What are the limitations of the available materials and processes?
 How is the designed product going to be regarded by the end users?

This is an individual NOT a group project. Each student will submit their own
design and make their own products. It is acceptable to discuss the design with
other students but don't copy their files or ideas, as that could be considered as
plagiarism.

Submission Requirements for this Report:

1. Market Research
The principle interaction with marketing and the design function happens through
the information provided by marketing; this influences the attributes of the product.
Information about the need of the buyer, together with the influence of competitor
product on the buyer is the stimulus for developing good products for the future.
You need to analyse and re-format this marketing information so it can meet the
buyer’s requirements.
2. Design Specifications
A design specification (DS) is created to ensure that the subsequent design and
development of a product meets the needs of the user and the function a product
is designed to perform. The DS report should show your understanding and
appreciation of this document. You need to use relevant details of customer
requirements (such as aesthetics, functions, performance, costs and production
parameters) to identify the design parameters with the level of risk involved. Using
the DS document, conceptual design solutions can be produced and evaluated to
select the optimum design solution. Using the customer requirements you must
develop a written specification considering all the relevant and important factors.
3. Concept Designs
This stage of the design involves drawing up a number of different viable concept
designs for the handle and clamp, which satisfy the requirements of the product
outlined in the DS, then evaluating them to decide on the most suitable one in
order to develop them further. Hence, concept design can be seen as a two-stage
process of generation and evaluation:
a) Generation
Typically, designers capture their ideas by sketching them on paper. Annotation
helps identify key points so that their ideas can be communicated with other
members of the team. It is important when designing a product that you are not
only consider the product design specification but you also should consider the
activities downstream of the design stage. Downstream activities typically are
manufacture, sales, transportation etc. By considering these stages early, you
can eliminate problems that may occur at these stages.
b) Evaluation
Once a suitable number of concepts have been generated (3-4), it is necessary to
choose the design most suitable to fulfil the requirements set out in the DS. The
design specification should be used as the basis of any decision being made. You
should evaluate each concept based on a number of angles or perspectives.
4. Final Design Drawings
The chosen concept should be developed in detail and in an appropriate form
using either hand or computer generated drawings with full dimensions and details
in preparations for manufacture.

All design relevant information should be extracted from appropriate reference

sources
