Function

This electric razor was manufactured by Conair. It is used for personal grooming, such as shaving or trimming of facial hair. It is able to provide a close shave or cut longer hair with included attachments.

How It Shaves

The motor is powered by two AA batteries and turns an offset shaft. The rotation of the offset shaft is translated into only horizontal motion by allowing the offset shaft to move freely within a vertical slit on the blade base mount. This in turn moves the moving blade against a stationary blade to cut hair.

User Requirements

-Shaver is able to cut hair

-Will not cut face

-Long battery life

-Fits into a human hand

-Can trim beards/sideburns

-Comfortable

Engineering Specifications

-Hairs cut per pass (%)

-Angle of blade (degrees)

-Motor Efficiency (%) or Battery life (time)

-Fits users grip (% of population)

-Adjustable length (mm)

-Vibration (amplitude)

-Users like it (%)
