The protective capsul
When we asses the accidents that are caused by
cars most of them will lead to deth ,harsh to mild
injury .this can be summerized under the table
below.
Selected
countries
Ethiopia
death
High injury
Mild injury
Little injury
Kenya
Somalia
As we have seen above the injury is very hard ,the
need to present this idea is the protective capsul
design is used to reduce the injury that is caused by
cars ,How?
Ans- the idea here is reduction of the injury at the
time of accident and perfectly protecting the driver
and the passenger ,this is done by protecting the
debris from reaching the driver and also resist the
the pressure that could arise at the time of the
accident this all requires a material,which is a capsul
,that is resistant to high pressure which means it
shuold have sizable bulk modulus and It should
have high resistant to heat like a grham postive
bacteria endospore,the membrane of the capsul
should be impermeable except to oxygen and non
toxic gas ,this means it should be selectively
permeable like a living cell plasma membrane .the
devising of this capsul requires to integrate
different properties to one material .as suggestion I
have put forwarded some materials that can be
used as raw matreial for this capsule.
Suggested design
Material – dissolved starch , the reason why I
choose this is water dissolved starch is
impermeamble to surface area starting from area of
hand punch and above . the proplem posed here is
that it is permeable to tiny debris which could kill
the passenger .
Mechanism – the mebrane of the capsule should
permit the entery of oxygen incase the passenge
rcould stay in it for a long time ,but when the
accident happens there could be toxic gas
emmisson whith different reasons so the
membrane should filter the air the rest is the work
of the lung . also at the time of the accident there is
production of high amount of heat due fire or
friction also ther is also sound energy , the design
should allow the mebrane to absorb this energy and
use it to destroy some debris that entered the
mebrane and the debris in its surrounding or absorb
energy and use it to bounce of materials around it
like the suit of the wakanda king .
