The wireless EC-screwdriver with tracking system
is an important innovation in vehicle assembly.
As a production man,
Alexander Steiniger
knows that a lot of
know-how and prot
potential can be found
in the production
process. At Porsche,
employees don’t
keep their ideas to
themselves, but

whether all screws are sitting exactly as planned – which is
animportant step within the extensive quality management
process.
All earlier EC-screwdrivers with a documenting function had
acable for the data transfer, which in real operations actually
has an advantage: as the space within which the screwdriver
can be used is restricted, this means that the stored screw
profile can’t be screwed into the wrong vehicle by mistake.
The 918 Spyder was our reference product for trying out the
wireless data transfer via Bluetooth. It is important that the
exact location of the screwdriver can be tracked so that its
stored radius for action is restricted exclusively to the correct
vehicle. The challenge was to find a solution suitable for
large-scale series production,” says Steiniger, describing the
starting-out position. “The result is a system that locates
theEC-screwdriver throughout the day. This means you can
besure that the screwdriver is only activated when it is at
the right vehicle at the right time. Furthermore, we found out
the locating system is so precise that we can even localise
the individual screw positions within a vehicle. That was the
real innovation, because it resulted in higher precision in the
production process.” This is because a wireless EC-screw-
driver with a tracking system can be allocated to the precise
coordinates of a specific screw position at any time. That
saves time for possible error searches and therefore means
less time needed for follow-up work. Another side effect
serving highest quality is also the fact that no cable comes
into contact with the chassis of the brand new factory vehi-
cles. This technology makes Porsche the benchmark in wire-
less documenting screwdrivers – and not only for the Group
itself, but also for other manufacturers.
At many places in the vehicle production process, Porsche
unites the manufactory concept with series production.
Maximum standardisation alongside highest individualisation
for the customer is the result. That’s the only way to achieve
premium products. And it is once again clear that it is the
individual that matters. Especially as individualisation will
continue to increase in the future.
“One thing is clear: we need men and women who actively
think about their work and how they can optimise it every
single day,” says Assembly Manager Steiniger. “Anyone who
doesn’t keep his ideas to himself, but discusses them with
his colleagues, is a real Porschean.” –––––––––––––––––––––––––––––––––––––––––––––––––––
