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.

Operation of the foldable camp – bed
The viability of the system
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
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.
