Assignment 02: Design for manufacture

Learning outcomes
The assignment should produce sufficient evidence for partial fulfillment of the following module learning outcomes:
Systematically analyse design problems, formulate and communicate solutions.
Appraise and justify the environment and business process framework of concurrent engineering.
Formulate and critically evaluate embodiment design solutions based on customer requirements, manufacturing
needs, and business objectives
Additional information
You may wish to use the LYXassignment/report template which you were shown in the workshop session for the presentation
of this assignment. On the title page of any submitted work a plagiarism/integrity statement should be in included, e.g.:
This assignment has not been submitted before at this or any other educational establishment of learning in the support
of a degree of any other award. As per the module specification, this second assignment accounts for 70% of the module
mark (the other 30% is by the first assignments). To pass the module, candidates must attain a minimum of 40% overall.
A threshold of 30% must be achieved in each of the assessments.
Resources: All resources required for this assessment are fully described in the main text of the assignment brief.
Special requirements: provided on a one-to-one basis for candidates requiring these.1 Background
As explored by candidates in the first assignment in order to produce a model/prototype of any product it is necessary to
ascertain the customer needs using a variety of techniques. The relative importance of the needs must then be established
by the design team and then from these data the PDS established. The team will then need to suggest a number of
accepted techniques, in order to produce a variety of marketable concepts. Moreover, any design must be supported by
necessary working drawing so that the product can be effectively manufactured as well as attempt to predict where the
component is likely to fail during service. These findings are then reported via an industrial standard report [1].
It is the purpose of this assignment to produce a concise Design for Manufacture (DfM) report in response to a clear
market need utilizing subject-specific techniques that arise from a specific design problem [1]. Candidates must report
on a pertinent conceptual design processes employed to produce a decent number of concept using if possible innovative
techniques. Given the number of particular product opportunities detailed in the appendix, it is the purpose here to
expose candidates to modern creative problem solving principles as detailed in the classic treatise [2] including TRIZ.
An appropriate unbiased method should be used to establish which concept best adheres to the target PDS. Using the
Computer Aided Three-dimensional Interactive Application (CATIA), AutoDesk-Inventor and in some cases ANSYSWorkbench
(i.e. not SolidWorks) to produce a basic conceptual model of the chosen concepts.
This assignment is an exercise in to producing relevant analysis of component designs and using these analyses in order
to finalize the design drawings and dimensions. The assignment also provides a vehicle by which to introduce the use of the
FE method within design to produce realistic prototypes which can be subjected to a variety of virtual testing protocols.
There is further scope to assesses particular methods and approaches employed by candidates, with an Assessment for
Learning (AfL) rationale. To this end a number of workshops with instruction given on how to set out documents in
specific academic and industrial document preparation systems (e.g. LYX) will be conducted as well as specialized CATIA
training. Students will be expected to produce a set of engineering drawings from CATIA (or AutoDesk-Inventor) using a
Design for Manufacture (DfM) philosophy. Candidates are actively encouraged to use a wide range of the universities LIS
facilities for seeking literature. Constructing a reference database in Reference Manager; importing references from WoK,
as well as writing a referenced article, i.e. cite while you write [4], thus avoiding Plagiarism (précis and peculiarity).
Note that as with all academic work the reference section must be adherence to with our preferred Vancouver [3] (or
Harvard) standard [5]. Where possible the completed document should not exceed fifty sides (say 8000 words) of A4
(excluding the title page, Figures, Tables and References). Any extra material not directly related to the demonstration/
achievement of the module descriptor learning outcomes should be include in an appendix proceeding the reference




2 Tasks
In order to to produce evidence of the first three specific learning outcomes of the University of Central Lancashire’s
module descriptor MP3731, candidates are expected to complete the following tasks.
1. Given the results from your previous assignment QFD [1, 2] produce at least twenty (yes 20!) key concepts using
TRIZ [1], In each case detailing in a log-book how TRIZ method(s) were employed to develop each of the concept.
2. By using salient concept screening and scoring methods [2] critically evaluate each of the concepts you have developed
hence finalize one to take forward for prototype development.
3. Using a valid product architectural method [2] to identify the main components producing a prototype of the your
product. {Task 3: 20 marks}
4. Use an Ashby’s material selection technique or otherwise in order to objectively decided on the materials required
to produce each component.
5. Use a basic FMEA to determine which of the components are most likely to fail under static and/or dynamic
conditions and perform an appropriate FEA on the component using the ANSYS software.

6. Verify one key analysis result empirically and/or using a complementary FE code (e.g. CATIA).
7. Produce a sales pamphlet and presentation introducing the launch of your product.
{Task 7: 10 marks}
8. Using the portfolio you have developed and appropriate literature (ispso-facto the reference section of this document)
together with dialogue with prospective stakeholder(s) produce and industrial report of your findings.
The final document should be type-written, using the LYX template (or otherwise) produced in workshops, and
contain the following main sections:
(a) Pre-report (title-page, Executive Summary, List of Contents, List of Figures, List of Tables etc) {3}
(b) Introduction (incl. the DfM process employed and Mission statement) {4}
(c) Market research {6}
(d) Conceptual design method {8}
i. Concept generation
ii. Conceptual development using TRIZ.
iii. Concept selection and reasoning
(e) Detailed design {10}
i. Design for Manufacture (DfM) philosophies
ii. Three-dimensional modelling
iii. Engineering drawings
(f) Product appraisal {6}
(g) Conclusions {5}
(h) Referencing {8}
i. Quality and discussion within the main text
ii. Adherence to acceptable standard
{Total task 8: 40 marks}
