GE 142 – Design I
Assignment 2
Individual Assignment
Fall 2022
RLO 1.2 Type B+ identify, develop, and characterize a basic engineering design problem
NB: this is the
first of two
assessments of RLO 1.2
The objective of this Design Assignment is to ensure that you are able to identify,
develop and characterize a basic engineering design problem.
More specifically, this
assignment focuses on problem statements, value propositions, functions, objectives,
constraints, and stakeholders.
The Design Problem Scenarios
Pick one of the four scenarios given at the end of this document.
Do some research to
help fill out the background on the design problem that you have chosen.
You can cite up
to two references for this assignment.
Once you have thought about the problem and
have done a bit of background research, you will be ready to complete the assignment.
The Deliverable
i)
Prepare a problem statement (one sentence) for this design problem, as per the
guidance given in your Design lectures.
ii) Prepare a value proposition (one sentence) for this design problem, as per the
guidance given in your Design lectures.
iii)
List up to two functions (primary or secondary) of any solution to this design
problem.
iv)
List 3 design objectives for this design problem.
For each design objective,
a. give it a name e.g.
durability
b. define it e.g.
the more durable, the better
c. justify the objective in 1-2 sentences e.g.
the client indicated that this is one
of the major drawbacks of the current solution to this problem
v) List 2 design constraints for this design problem.
For each design constraint,
a. give it a name e.g.
purchase cost
b. define it e.g.
the product must not cost more than $500
c. justify the constraint in 1-2 sentences e.g.
the scenario indicated that the
cost of the competitor’s product was $500 and that cost was a concern
vi) List at least 3 potential stakeholders for this design problem and describe what
each of them have at stake.
Note that you may use your references for the purposes of justifying your design
objectives and/or constraints.
Or you might learn about some potential stakeholders, or
something about the value proposition.
Submitting Your Work
You will prepare your submission on word processing software such as MS Word.
You
will then save it as a PDF and upload the PDF to Crowdmark by 10 pm on Sept. 23
rd
.
At the top of your document, create a header with your name, NSID, the title “Design
Assignment 2”, and the name of the Design Problem Scenario that you have chosen.
Your document must not be more than 2 pages in length, all in.
This includes the header
information, your answers to the 6 parts of the exercise, and up to 2 references that you
might cite in your answers.
Use APA for any references/citations.
Use font size 12
(Calibri, Times New Roman, or Arial) and single line spacing.
Your graded Assignment will be returned to you the following week. No late assignments
will be accepted after 11:59 pm on Sept. 23

Design Problem Scenario I – Cat Feeding
Cats require regular feeding; however, owners often forget or don’t want to prepare
meals. Additionally, owners sometimes want to travel for a long weekend while
providing delicious feline sustenance to their cats that remain at home. Sometimes, cats
will steal each other’s food, causing one cat to get fat and another cat to starve. Some cats
require specialized food that should not be shared. These cats cannot be allowed to eat
each other’s food and cannot be allowed constant access to their own food.
Design Problem Scenario II – Energy Distribution
Across North America the average household power consumption and demand on the
electrical grid is increasing. Energy prices are forecast to increase over much of the world
over the near future. Over the last few years failures of the electrical grid have created
significant challenges to households. A large grid failure in the Canadian prairies could
cause safety concerns to individual households.
Design Problem Scenario III – Home Air Exchange
Household air needs to be regularly exchanged. Modern automated air exchangers move
air through heat exchangers at regular intervals (or when humidity is too high). However,
these air exchangers sometimes bring warmer air into the house during hot days when the
air conditioner is running, instead of waiting a few hours to bring in colder air. Also, air
conditioners attempt to remove heat from a house often during the hottest part of the day
because that is when the house it at its hottest. Additionally, the outside component of the
air conditioner is often placed either in direct sunlight or a nook with poor ventilation.
Design Problem Scenario IV – Automotive Safety
Wildlife collisions are an important safety consideration on Saskatchewan highways,
especially at night. Wildlife can be difficult to see at night. Brighter headlights, with
higher beams, can help drivers to see wildlife in time to avoid collisions, especially if the
headlights illuminate ditches far ahead. However, brighter headlights can blind oncoming
traffic. Some headlights are brighter, project different colors, and project different
patterns. Hitting large wildlife or blinding oncoming traffic can cause serious safety
problems.
