Design specifications:
·
The design is secure and will not come apart
·
The design makes use of lightweight materials
·
The design uses purposeful insulation around the
egg
·
The design utilises a container shape/design
·
The design has a minimum of four materials
|
|
A need’s analysis for the
challenge:
|
|
What is the motivation/purpose for the design?
|
To solve a real life technology and design problem within a famous
nursery rhyme.
|
Who will use the product/system being produced? What is their age,
characteristics relevant to the design? How will you find out what their
needs are?
|
The system being produced will only be used by this class and the
students as a problem solving challenge.
|
Are there any stakeholders to consider?
|
No.
|
What is the need being met through the design?
|
The Year One students will challenge their design and thinking skills
and they will learn the process and practice computational thinking as well
as design thinking.
|
What alternatives are already available? Why is this design better?
|
Egg cartons are available. The invented designs will be better because
they will be built with a drop from a height, in mind.
|
Are there any constraints to the degree of freedom that you have in
creating the design?
|
Specific materials list, minimum number of inclusions.
|
What research will be needed to develop an understanding of how the
design and manufacturing process will be enabled, what processes developed by
others can be used?
|
· Research
insulating materials
· Look at the
properties of common materials
· What do humans
use to fall safely to the ground?
· Look at
particular design that failed and evaluate why, and justify the answer. The
teacher will facilitate discussion and help with the processes of attaching
and binding materials together as this is always an area of difficulty in the
early years.
|
What manufacturing constraints will influence the design – cost,
equipment, safety, time?
|
Only materials indicated by the teacher can be used because cost is a
factor. There will be a need to re-use as much materials as possible. No hot
glue guns or staplers as a safety precaution. We will only get a lesson to
build a design, and another lesson to evaluate and re-design after a test.

Design Technologies – Evaluation of Marketed
Product

|
Name
of the producer

Tamara

Brief
description of product being evaluated
|
This
product is a design that was created out of a problem-based scenario in a
classroom: ‘How can we protect an egg from cracking if we drop it from a
height? The product is built to safely house an egg when dropped. It consists
of a container, string and parachute top.
|
How
aesthetically pleasing is the product and why?
|
The
product is not particularly pleasing to the eye. It is made from newspaper
and the parachute element sits limply beside it.
|
What
does the product do?
|
The
product protects an egg when it is dropped from a height.
|
How
does it work?
|
The
insulative properties of the foam, helps keep the egg cushioned from impact,
whilst the plastic bag parachute resists the air on its way down, aiding the
severity of impact.
|
Is it
well built?
|
No,
the design base, or container is not well built. The string and parachute are
secured, but there is a risk the string could come through the holes.
|
Does
it use lightweight materials?
|
Yes, the
plastic bag, string and foam is light.
|
Does
the product insulate the egg?
|
The
foam inside the container insulates the egg.
|
Who
would use the artefact?
|
This
artefact would be used in the classroom, to show how design thinking can come
up with ways to overcome problems.
|
How
socially responsible is it to produce the product?
|
All
materials in the product are recycled materials. Yet, the product is not made
for longevity, so these will have to be thrown away, limiting the integrity
behind the use of recyclables.
|
What
do you particularly like about the product?
|
I like
the product’s use of science and air resistance to aid other design concepts.
|
What
improvements can be made?
|
The
base of the design should probably be paper mache to give it strength, or even
a small plastic container, or styrofoam cup. Perhaps helium balloons could be
used to create a gentle fall to the ground.
