Abstract
Problem statement
This master thesis was initiated since today, when developing a new mobile phone at Sony Ericsson, it is difficult to get a perception of the ergonomics and the tactility of the keyboard before the first design prototype (DP0 and DP1) is built. The SLA block model used today is completely solid and consequently a secured decision of the final design can not be made in this phase.

After the first prototype build is done, it is complex and expensive to make major changes in the keyboard design. Before the DP1 is build, designers and engineers still are relatively free to make alterations in the design.


Purpose
Investigate the possibilities and the best way to implement a mechanical keyboard in the concept... (More)
Problem statement
This master thesis was initiated since today, when developing a new mobile phone at Sony Ericsson, it is difficult to get a perception of the ergonomics and the tactility of the keyboard before the first design prototype (DP0 and DP1) is built. The SLA block model used today is completely solid and consequently a secured decision of the final design can not be made in this phase.

After the first prototype build is done, it is complex and expensive to make major changes in the keyboard design. Before the DP1 is build, designers and engineers still are relatively free to make alterations in the design.


Purpose
Investigate the possibilities and the best way to implement a mechanical keyboard in the concept mock-up with the purpose to be able to secure the keyboard design in an early stage of the development process.


Method
The master thesis is conducted via benchmarking, brain-storming, interviews and consulting with people holding specific knowledge in the different areas. With the SLA-machine in the prototype workshop at Sony Ericsson a lot of tests and iterations have been made in order to find out the best practical solution and appropriate tolerances.



Conclusions
The master thesis has shown that it is possible to implement a mechanical keyboard in the concept mock-up with the SLA-process, using one of the concepts developed in this thesis. In comparison to the solid block-SLA model, the mechanical mock-up supplies a tactile apprehension of the keys, valuable for designers and product planners. At the same time the block model with its uncolored outside, is still just a draft of the final
hand set.
Alongside this thesis a guideline has been produced based on the results from the tests. This guideline contains the procedure of how to create the mock-ups and certain dimensions and tolerances to consider when creating a mechanical concept mock-up. (Less)
