s that were
not designed ergonomically. Also, the task method
was not designed following ergonomic principles.
The assembly task involved picking up the switch
base and cover from the bins, assembling all the
inside parts in the base, putting the cover, tightening
the assembly using a screwdriver and placinlg it in the
outgoing bin. The steps of the assembly task were
modified in the new design considering motion study
and ergonomic principles. A jig was designed and
used in the performance of the task on the smart
workstation. A power screwdriver was used for
tightening the cover in the modified task method.
