Engineering Design and Workshop Technology skills are
considered to be of high importance for the modern engineers. The module in
scope aims to the understanding of the procedures that have to be followed
during the development stages of a new product. Thus, given specific customer
requirements, students will be given the opportunity to develop and built a new
Students will be assesed through two written
asignments that are to cover the procedure of product design and manufacturing
of a mechanical assembly. Also, manufacturing skills will be taken in
consideration as workshop equipment will be used for the prototyping of the
The present assessement sheet covers the following
1. Develop a design specification that establishes
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
Thus, students will be given a specific set of
customer requirements and appropriate actions should be taken in order to carry
out the procedure of Engineering Design of a product that covers the given
requirements. At the end, an Engineering Report has to be given in order to describe
the actions that have been taken in order to overcome the intermediate stages
of Engineering Design. Also, detailed Engineering Drawings will be included at
the Engineering Report. The Engineering Report should have a length of 1500-2000 words.
Engineering Design Scenario and Initial Customer
Your customer, a toolmaker asks you to
design a tap wrench that is appropriate for use with standards metric taps in
the range of M3-M8.
that the product is shown just for reference. Your product should respect the
customer‘s manufacturing capabilities include injection molding of plastic
parts, machining and precision ginding.
are alowed to design anything you want as long as the designed product can be
manufactured in-house. Also, you should consider designing the tap wrench respecting
the manufacturing related issues involved in the economic mass production of
the designed product.
Assignment Key Points
Students should consider the following key points so
as to fulfill assignment requirements.
à Market Research
Taking in consideration the given customer
requirements, students should perform a market research along with a competition
analysis. This procedure is to extend the customer requirements and determine
the basic features that lead to justification of the product.
à 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 also ensure the function a product is designed to perform. The DS report
should show student understanding and appreciation of the DS document. Students
need to use relevant details of customer requirements such as aesthetics,
functions, performance, cost, 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 students must develop a written
specification considering all the relative and important factors.
à Concept Designs
This stage of the design involves drawing up a number
of different viable concept designs which satisfy the requirements of the
product outlined in the DS and then evaluating them to decide on the most
suitable one in order to develop further. Hence, concept design can be seen as
a two-stage process of generation and evaluation.
à Final Design Drawings
The chosen concept should be developed utilising
computer technologies and detailed manufacturing drawings should be exported.
The generated mechanical drawings have to fully define the digital prototype.
Also CAD files of the solid models and 2D drawings must be submited.
The marking of this assessment will be based on the
Including structure of report,
contents page, brief, introduction, references and appendices.
Including existing products,
competitors chart, market survey, analysis of results leading to
justification of the product.
Including structure, relevance and
accuracy of information in relation to specific products.
Including the drawing up of a number
of different concepts and then evaluating them to decide on the most suitable
Including final design CAD files and
complete sketches with dimensions

no automatic rights to late submission, with a capped
mark of 40%. However, the University acknowledges that there may be
circumstances which prevent students from meeting deadlines.
There are now three distinct
processes in place to deal with differing student circumstances:
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. For further details refer to the link below:
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
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.
"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.
be aware that should the marking reveal the possibility that the work submitted
is not that of the student, then a verbal examination (VIVA) and interview will
be conducted to ascertain the validity of the work.
