Selected Prototype Prototype design
(Describe how should it work, and how (Sketch here or attach a printed copy)
does it represent the selected solution)
In the need to generate energy from
school activities , mechanical energy
generated by students motion is one of
the solutions that would be efficient for
this semester capstone challenge. The
prototype is a modified footsteps
electricity generator .Its working
mechanism is summarized in the
following steps:
1-A force is applied on the plate by
student, spring gets compressed, as a
result the rack moves vertically down.
2-The pinion meshed with the rack gear
results in circular motion of the pinion
gear.
3- The intermediate gear with more
number of teeth will rotate as a result of
motion of pinion.
4-The generator attached to the
intermediate will obtain the rotating
motion, hence results in the
sinusoidal waveform (for single
Generator).
5-The obtained voltage is passed
through diode to be converted to dc.
,From here the power is stored in
battery and reused to operate a led
lamp.
