Different perceptions of the ignition interlock system, a standard of public safety
at the same time without taking away the beauty of one’s vehicle interior. As a
result we will design our Voog Breathalyzer Ignition Interlock System to be a
wireless unit. Voog will be consisting of a handheld unit and a control box. With
no wires attached to the handheld unit, user can easily storage it in their glove
compartment of the vehicle or take it with them in their bags or purses to use it as
a standalone unit at various social functions. The control box unit will be serving
as a communication hub between the hand unit and the vehicle’s internal relay.
The control box will also be hidden behind the vehicle’s dashboard, this way we
can eliminate the unnecessary wires and can make significantly more appealing
to the general public.
Accuracy of the breath-analyzing unit to detect alcohol content in the blood will
be core of the entire design. It is understood that no matter how many features
our unit possess and how appeal it might be, with it being under the acceptable
accuracy level, not a single person will adopt it voluntarily or involuntarily. In
order to achieve the desirable level accuracy, we will explore all option of sensor
choices ranging from traditional semi-conductor sensor to intuitive design of
multiple sensor designs and to the highest industry standard, fuel cell sensors.
Without doubt, ultimately cost will determine if auto manufacturers and the
federal government would want to adopt these systems. We have kept cost in
mind throughout our entire design process, from adopting the existing
mouthpieces available in the market to achieve a lower cost than reconstructing
our unique mouthpieces at a higher cost to exploring the option of utilizing multi
semi conductor sensors instead of the much higher cost fuel cell sensors.
With all our goals and objective in mind, we are motivated to develop a
competitive and functional Breathalyzer Ignition Interlock System that we are
sure will make a difference in saving lives and preventing drunk driving.
1.4 Comparison of Existing Products
Within our scope of research, it is not common for any breathalyzer ignition
interlock system to have the hand-held unit working independently as a
standalone unit as well, therefore throughout the duration of our research and
comparison, we will be reflecting our design with two existing products, Ignition
Interlock system and hand-held standalone breathalyzer unit.
Breath alcohol testers, also known as breathalyzers and many other names are
generally labeled into two separate categories, personal and professional.
Although, its broken into categories, they share the same functions of breathe analysis,
a common method of testing for blood-alcohol content in use today.
Breathalyzers estimate the concentration of alcohol in the body by measuring the
amount of alcohol exhaled from the lungs. The difference between two are, most
