ABSTRACT
In this
project, three alternative design solutions were considered for the foldable
cam – bed. The authors utilize the local materials (with cost consideration)
for the components. The merits and demerits of each of the alternative with
respect to the considered group were also discusses and the solutions of the
alternatives that best satisfied the limitations were selected for production.
The material selected design and cost analysis, production processes and
operation maintenance and problems encountered during the design were also
included.

1.0 INTRODUCTION
Camp bed is used
universally for relaxation, emergency eases such as war and in other several
ways, it is the acknowledgement of these resources that led to the design of
the foldable camp – bed. All the existing foldable camp bed, have almost the
same dimension but differ in design. Some use rope and ailets while the modern
design make use of wood and spring. Some other are constructed using straight
bars, pipes of angle iron.
1.10 LIMITATION
OF ALREADY EXISTING FOLDABLE CAMP – BED
Some
foldable camp beds are made of Iron bars which are too heavy and cannot be
carried with ease. Most existing foldable camp – bed are cumbersome to carry
because their lengths which are normally six feet or 183 meters or 1830mm.
Some of the
materials used for fabrication of the foldable camp bed may not be locally got
and this affects its prince, making its availability to become more rare.
In the market, design that make use of
springs to hold the improvised materials or even wood are found. But when the
spring fill off, its efficiency is reduced and this make it more profitable to
make use of wood than spring to hold improvised mattress.
DESIGN SPECIFICATION OF THE
FOLDABLE CAMP BED
It is high in weight
It can be
produced locally
It is
portable
It has an
in built head rest which is adjustable. The tarpaulin material used in folding
the foam to the wood can be easily removed along with the wood for cleaning.
It is could carry a person up to 75kg in weight. Pipes (square) used are
made of galvanized steel and also the angle Iron used is made if galvanized
steel both painted with aluminum oil paint to avoid corrosion.
It is easy
to manipulate.
All these specification put together make this project a viable one that
can compete favorably with any existing foldable camp bed and also eliminate
the limitations posses by earlier designers.
