Design Problem and Problem Analysis
Introduction
On this slide, I have presented my design problem and problem analysis. In order to identify the problem I have looked at existing problems in products already in
the market. Throughout the product analysis I hope to identify the design specifications that must satisfy my product in order to be successful.
Design problem Figure 2
When boiling an egg, I discovered a number of problems. First of
all, one has to be careful that they do not place their hands too close
to the water or saucepan – in order to avoid burning. Also, one must
be careful not to crack the egg when placing it into the saucepan, as
this would ruin the egg. One must also be careful that they do not
overcook their egg, as this may cause the egg to crack or be too
hard

Figure 1

Figure 2 shows that it can be quite difficult to manage to balance an egg
on a spoon when taking it out of the saucepan. This would be especially
hard for an elderly person wishing to make themselves a boiled egg. As
well as this, you also have to take each egg out one by one, which is not
a very practical way of taking them all out. As well as this, it is very hard
to be able to tell when an egg is cooked, but there are methods of doing
so. Obviously, everyone knows that there is time, which can give a rough
answer as to whether the egg has been cooked, by knowing how long it
has been boiling for. However, another method is by taking the egg out,
and watching for condensation around the egg, and if condensation does

Design Brief

Introduction Figure 1
On this page, I have presented my Design Brief
and Major Design Specifications. The design
brief is the statement of intent which states the
aim of the project. The design specifications are
criteria which the product must satisfy.

Brief

To design and manufacture an egg holder that
can support an egg whilst in a saucepan. The
product must be able to hold the egg securely
and be able to be removed with ease. It should
also be able to hold at least two eggs.
Major Design Specifications

The product must::
• Be able to be easily removed from the
saucepan once it has finished boiling, as
otherwise it would defeat the object of why
the product was made.
• Be able to hold at least 3 eggs so that if for
example the consumer wishes to boil 6
eggs, they don’t have to boil 2 eggs on 3
occasions.
• Be able to be used in a range of different
sized saucepans so that the consumer
doesn’t have to have a specific sized
saucepan when using the product.
• Be able to keep the consumer safe from
burning themselves on either the saucepan,
or the boiling water. Figure 1 shows my drawings of my first initial ideas for my project. The drawing on the left hand side

Market Research
Introduction Questionnaire
On this slide, I have presented the questionnaire for
my Market Research. Market Research looks
specifically at what the consumer would desire from
a product. One way of discovering this information is
by using questionnaires and surveys. Marketing
Research is research that gathers and analyzes
information about the moving of good or services
from producer to consumer.

Method
Producing and handing out a questionnaire is an
individual practice. I will start my Market Research by
carrying out a survey using a questionnaire. It will
consist of questions on the current methods of boiling
an egg. Those asked to participate in the
questionnaire will be people who have experienced
boiling an egg, and be those who regularly come
across the problem. At the bottom of the
questionnaire, I will leave a space in which the
person filling in the questionnaire may sketch any of
their own ideas concerning the aesthetics and
function of the product.

Conclusions
On the following slides, I will present the results from
the questionnaire using pie charts, graphs and any
other methods that I deem necessary. It is hoped that
through the analysis of the results, detailed design
specifications will be formed.

Conclusions
Now that I have a good idea about what people would want my product to look like, I can now start to think of things that I could include in my
designs. There is not that much from either of these two design ideas that I would wish to incorporate with my final design. However, I will be
considering some of the aspects of the design idea shown in figure 2. For example, I may consider having two parallel strips which would rest on the
saucepan.


Market Research – Competing Products

On this slide, I have presented my analysis of
competing products already on the market.
Analysing existing products is an important
exercise as it will help me form design
specifications as that may help focus my design
ideas. Also it may allow me to identify design faults
with products so that I can design a new improved
product. Finally, it will also provide me with good
design ideas and design elements that I may try to
incorporate in my design.

On this slide I will analyse the materials which the product has been made
from. I will also look into why the materials were used and whether or not
they are appropriate. I will also analyse the manufacturing process of the
product and assess whether it is a suitable way to make my product.

Conclusions
On the next few slides I will be continuing
with the product analysis section and will
be looking at the aesthetics of the
colander.


Product Analysis - Aesthetics

Introduction
On this slide I will be analysing the aesthetic qualities of my colander. Aesthetics are ultimately to do with how easy a product is on the human eye, and whether or
not the product looks good. Essentials of aesthetics may include; color, shape, texture, form or other features of the product. Also on this slide I will analyse the finish
of the product. I will identify the various finishing techniques used and also observe whether or not those techniques are efficient.

Shape and form
Figure 1 Figure2
The shape of the colander is bowl-shaped. This design is
practical for boiling things with as the product has many small
holes in it (with a diameter of approximately 4mm). However, it
is quite difficult to clean the colander in some places. The
edges of the product are curved so that the consumer is in no
danger of being cut by the product. From an aesthetics point of
view it is quite a good-looking product.. The handles of the
colander are curved and rounded, however are not comfortable
to use as the edge of the colander digs into ones hands when
being held. Also the circular base provides stability when
placed on a flat surface.
Texture
The texture of the colander is smooth, however, the small
holes on the colander slightly affect the feel of it. However it is
quite tricky to hold the colander by its handles, as if one has
sweaty hands, then they may find it difficult to grasp a firm grip
of it.

must be well finished, giving the product more durability and maintaining good aesthetics.

be in. I will therefore investigate why the colander
has been shaped in the way it has. Figure 1 Figure 2

Function

The function of the colander is quite easy to
understand. It works by providing a large bowl-
shaped structure in which the user may place
whatever they wish inside. The small holes
within the colander allow for water to flow in and
out of the colander with little delay. The colander
has two handles, however, when the colander is
being used, it is not possible to use them both if
the user wishes to hold something within the
colander (Figure 4). The flat base attached to the
bottom of the colander allows for it to be placed Figure 3 Figure 4 Figure 5
on a flat surface with tipping from side to side.
Conclusions

From my product analysis, I have come up with a
number of specifications.
The product must:
1) Not have many, if any corners.
2) Be easy to clean after use.
3) Be easy to hold, (with one hand if necessary).
4) Allow water to flow through it with ease.


Mood Board

Introduction

On this slide I have presented my Mood Board. A Mood Board is a selection of images of products that relate to the problem in some way. These products may
give oneself inspiration in the design of their product.

Conclusions

I based my decision when choosing which images that I wish to place on my mood board mainly on quality, shape and relativity to my product which I would
like to design. I like the idea of kitchen utensils being made out of stainless steel, as I believe that it gives the product a more aesthetically pleasing
look, and they always are made to a high quality finish. By doing this exercise, I have been able to improve my ideas as to what size the design must
be, and the quality of the finish that I feel it should have.

Initial Ideas – Buzz Page

Introduction

On this page, I have presented my Buzz page. In this stage of my project, a few of my classmates were asked to draw and render an initial
idea of their own. These designs expand my view on the design of my product.

Figure 1 Figure 2 Figure 3 Figure 4

Figure 5 Figure 6 Figure 8 Figure 7

Figure 9 Conclusion
This page of designs enables me to get a wider perspective on possible design ideas for my product. This
buzz page is the basis of ideas for the final product. More detailed designs will be drawn, which will be
accompanied by CAD drawings.


Initial Idea 1


On this slide, I have presented my first
initial idea, using my own drawing skills.
My first initial idea is a shape similar to that
of an up-side-down umbrella, with five slots
capable of holding one egg each. It has a
rubber handle, in order to prevent the user
getting any burns, whilst its main body and
shaft is made out of stainless steel. As you
can see in my drawings, it would fit
adequately in to a regular sized saucepan.
Conclusions

Pros:
1.It is a unique design
2.It would hold a sufficient amount of eggs
for a family of five.
3.It has a modern, and slick look.
4.Due to it having a unique method of
gripping it, when it gets lifted, the centre of
gravity of the product is in the centre of
it, so it doesn’t tip to the sides.

Cons:
1.The eggs may get pushed out of the slots
by bubbles when they are being boiled, and
therefore defeat the object of the product.
2.The eggs may not boil at the same heat
throughout them, as the product may
insulate the bottom of them.
3.Water may not drain through the slots for
the eggs.


Initial Idea 1 (continued)


On this slide I have continued in
presenting my first initial idea.
However, as you can see, I have
done so using CAD, on the
computer.

Conclusions

Pros:
2.It would hold a sufficient amount of
eggs for a family of five.
4.Due to it having a unique method of Figure 3
gripping it, when it gets lifted, the centre
of gravity of the product is in the centre of
it, so it doesn’t tip to the sides.

Cons:
1.The eggs may get pushed out of the
slots by bubbles when they are being
boiled, and therefore defeat the object of
the product.
3.Water may not drain through the slots
for the eggs.


Initial Idea 2

On this slide, I have presented my second
initial idea, also using my own drawing
skills, and also using CAD. My second initial
idea is a shape similar to that of my first
initial idea, however, there were some
features which I decided that I wished to vary
slightly. For example, first of all, I was
looking to use a different handle for my
product, so I came up with a simple, regular-
shaped handle as shown in some of the
figures to the right.. I also wished to
experiment with the way in which the product
would hold the eggs, so, I decided to get rid
of the slots for the eggs, and use a circular
Conclusions
rack instead.

Pros:
2.It would hold a sufficient amount of eggs
for a family of five.

Cons:
1.If the user is only boiling one or two
eggs, then the product would not balance
well.
3.Water may not drain through the slots for
the eggs.



On this slide I have
continued presenting my
second initial idea.
However, as you can
see, I have done so using
CAD, on the computer.

Figure 2
Conclusions

Pros:
2.It would hold a sufficient
amount of eggs for a
family of five.
3.It has a modern, and
slick look.

Cons:
1.If the user is only boiling
one or two eggs, then the
product would not balance
well.
2.The eggs may not boil at
the same heat throughout
them, as the product may
insulate the bottom of
them.
3.Water may not drain
through the slots for the
eggs.


Initial Idea 3


On this slide, I have presented my third
initial idea, also using my own drawing
skills, and also using CAD. My third initial
idea is an egg holder with a rack which
would hold a maximum of four eggs, and
a long z-shaped handle which would
provide the user with sufficient leverage
to lift the holder. When placed on a flat
surface, the egg holder would be able to
balance well without the aid of any
support. The slots which would be used
to hold the eggs would have very smooth
edges, so that the eggs inside would be
in no danger of cracking. This idea also
has a rubber grip attached near the
handle, which would allow the product to
stay secure when in the saucepan.
Conclusions

Pros:
1. The egg holder would be able to
balance on a flat surface without
any support
2. The egg holder would be able to
firmly attach itself to the rim of a
wide range of sizes
Cons:
1. It would not be able to fit
comfortably in a saucepan with a
diameter of less than 190mm.



Introduction

On this slide, I have presented my fourth initial idea. To do so, I used CAD, as shown below in figures 1,2,3
and 4.
Figure 1 Figure 2 Figure 3

Conclusions

Pros:
1. The egg holder would be able to balance on a flat surface without any support
2. The egg holder would be able to firmly attach itself to the rim of a wide range of sizes
Cons:
1. It would not be able to fit comfortably in a saucepan with a diameter of less than 190mm.


Modelling - Diary of Manufacture

Introduction Figure 1 Figure 2 Figure 3

On this slide, I will be presenting my modelling for my
first initial idea Modelling is the act of representing
something, however it is usually done on a smaller
scale. Modelling is important for many different
reasons. It is important as by doing so, one has the
opportunity to test for:
•Function
•Durability/strength
•Weaknesses
•Suitable materials Figure 1 shows the block of Figure 2 is an image of me when I Figure 3 shows the plainer that I

It also helps when suggesting any other possible
improvements that could be made to the product.
