4.1
Introduction
We have now decided which concept we will use, and by selecting this solution we can
separate it down to sub concepts. The whole assembly consists of both mechanical and
electronic problem that needs to be solved, and by breaking it down to sub concepts it is
easier to detect the problems that might occur. We will now list the sub concepts and
complement them further on in this chapter:

Material selection

Attachment of housing to accumulator

Transmit laser beam into the accumulator

Fitting the laser to housing
