Degrees of Freedom
First of all the Degrees of Freedom (DOF) need to be considered. In total there are six DOF that can be included (3 linear x,y,z; 3 rotational), but each DOF makes the manufacturability of the prototype more difficult. Also, not every DOF is important to achieve the end result, which is a monitor arm that reduces neck and back complaints. Looking at the Ideal monitor guidelines, it was decided that the prototype will receive 3 DOF. The first one is a linear movement in the z-direction, to adjust to the body length of a person. The second one is a rotational movement in the xy-plane, to adjust to the angle at which the user is behind his or her desk. The final DOF is a linear radial movement perpendicular to the rotation in the xy-plane. This adjusts the distance at which the monitor is from the user.
