Toys N More Fundamentals
Project objectives:
1. Use toy analysis to demonstrate product marketing, design, safety factors,
manufacturing methods, and design refinement
2. Allow students to redesign their product with prototype and explore “value
add” features to the product
3. Have students take ideas learned from off the shelf toy product and apply them
to a product development effort from a single problem statement
4. Students to complete a presentation and written report documenting effort and
project details

Toys Projects:
6 project toys ranging from simple to
complex and wide scope of age group
4/13/2010 Toys N More ETCE meeting 4
Design Criteria:
1. Marketing
1. How is the toy packages and sold to intended audience?
2. What features separate this product from other similar products?
2. Purpose of the toy
1. Educational vs. entertainment
3. Toy manufacturing
1. Ease of mass assembly, what features indicate mass production
2. Cost of manufacturing; what was done to reduce costs yet meet needs of toy
3. How is the toy powered
4. Safety
1. What safety features are incorporated into the toy
2. Is the toy safe for the intended age group
5. Improved design
1. Cost and manufacturing methods to improve current design

Problem Statement
To design and fabricate a solar cooking device for a South African Nation
•Your team has been asked to develop a solar cooking device to heat water to a high enough
temperature to prevent dracunculiasis and other waterborne diseases.
•Your team has been asked to develop a mobile solar cooking device. The device must be
easily transported by folding flat and be able to cook a hotdog in a reasonable amount of
time.
•Your team has been asked to design and build a prototype of a solar cooking device to cook
one can of soup in less than 40 minutes.

Solar Cooking in South Africa
The Solar Cooker Project not only serves to protect
women, but also provides them with income
opportunities through manufacturing solar cookers,
training others to use the cookers, and making carrying
bags to increase the cookers life span. It gives the
women a sense of pride to be able to contribute to their
household. This project is active in the e Iridimi,
Touloum and Oure Cassoni refugee camps in Chad.
Jewish World Watch plans to initiate this project in
other refugee camps with the goal of reducing the
number of crimes committed against refugee women.
•Firewood and clean drinking water are the two biggest challenges
threatening traditional and modern African lifestyles, representing two
key aspects capable of destabilizing entire regions
•Southern Africa has least access to grid energy of any region on
earth with less that 20% of its 300 Million residents 'connected'.
Africa also has some of the highest concentrations of sunlight on earth
making it ideally suited to benefit from Solar energy

•There are a variety of types of solar cookers: over 65 major designs and hundreds of variations of them. The basic principles of all solar
cookers are:
Concentrating sunlight: Some device, usually a mirror or some type of reflective metal, is used to concentrate light and heat from the sun
into a small cooking area, making the energy more concentrated and therefore more potent.
Converting light to heat: Any black on the inside of a solar cooker, as well as certain materials for pots, will improve the effectiveness of
turning light into heat. A black pan will absorb almost all of the sun's light and turn it into heat, substantially improving the effectiveness
of the cooker. Also, the better a pan conducts heat, the faster the oven will work.
Trapping heat: Isolating the air inside the cooker from the air outside the cooker makes an important difference. Using a clear solid, like
a plastic bag or a glass cover, will allow light to enter, but once the light is absorbed and converted to heat, a plastic bag or glass cover will
trap the heat inside. This makes it possible to reach similar temperatures on cold and windy days as on hot days.
