Abstract
The aim of this report is to investigate the possibilities of an automated process which
will identify and separate worn out granules and thus ensure an optimum cleaning
performance. Research shows that some users are not following the recommendations
regarding when to change Granules, leading to reduced performance and a reduction
in sales.

The first phase of the project involves studying how the Granules’ shapes and sizes
changes during its lifetime. The report will also analyse the manufacturing process to
see what variations there are in terms of tolerances, run different test to determine the
critical or limiting Granule size and finally try to understand the users’ behaviour and
the market aspects. Primarily the aim is to... (More)
The aim of this report is to investigate the possibilities of an automated process which
will identify and separate worn out granules and thus ensure an optimum cleaning

The first phase of the project involves studying how the Granules’ shapes and sizes
changes during its lifetime. The report will also analyse the manufacturing process to
see what variations there are in terms of tolerances, run different test to determine the
critical or limiting Granule size and finally try to understand the users’ behaviour and
the market aspects. Primarily the aim is to identify the potential in improving the
cleaning performance and user friendliness.

However, it is shown that the change in size and weight over the Granule’s lifetime is
not significant compared to the new Granules standard deviation due to imprecise
manufacturing methods. Different aspects of the problem are discussed.

The second phase is to establish some essential evaluation criteria (whether the device
is user friendly, cost efficient and what the possibilities are in terms integration) and
to identify various methods for separation. The most feasible ideas such as separation
by flowing air and by using various types of filters are studied and further developed
during the third phase into a final concept. Various tests have been run to establish if
the concept is technically possible and to solve some initial problems.

Finally, as various prototypes and tests have shown this method (an automated
process) to be quite a complicated and therefore expensive solution to ensure an
optimum cleaning performance some other suggestions are given. One idea, which
would be very easy to implement, is to simply notify the user via the interface when
the total Granule volume drops below the recommended limit. (Less)
