Alternate Solutions and Pros and Cons

Divergent Nozzle

This nozzle has a small chokepoint to connect to the tube transferring the pneumatic flow, yet has a large opening to push out the air (Figure 1). This design applies all of the pneumatic force over a larger surface area of the object that will be moved.
The connector tube will have to be longer to gain a further reach, as the energy being released from the nozzle, while it will spread out the force over a larger surface area, will not be as powerful as it would if the nozzle opening was smaller (Figure 1). The additional reach will compensate for the lack of precise air pressure.

However, regardless of the decreased air pressure, the objects will be far easier to accurately move around due to the larger surface area of the pneumatic flow and longer reach of the tube. Conversely, because of the longer tube, the overall accuracy of the tube movement will be significantly lowered as there is a lot more to move, and little structural support to keep it entirely upright and straight when in motion.

The divergent nozzle will be manufactured by employing a wooden structure. This would provide the most solid and sturdy nozzle that could withstand any amount of pressure. However, it would be fairly difficult to sculpt from wood, as it is rather small nozzle and would probably not come out the way that it would appear in the speculations of our planning.

Convergent Nozzle

Opposite of the divergent nozzle, the convergent nozzle has the chokepoint in the opening of the nozzle, and has a large connection to the tube supplying the air pressure (Figure 2). This design applies a focused blast of pneumatic energy upon a small part of the object that is to be transferred in location.

The connector tube will be shorter than that of the connector tube of the divergent nozzle (Figure 2). By shortening the tube from the previous design, the tube and nozzle will be far easier to direct precisely and apply the focused pneumatic force wherever it is needed.

With the convergent nozzle design, excessive airflow will be forced through a small opening, thus increasing the overall force of the flow and yielding a higher energy output. With this higher energy output, it will be far easier to move the objects with relative ease. Unfortunately, the smaller tube, while more accurate, will have less room to maneuver and cannot reach as far as a longer tube could.

Molding clay will be applied to create this nozzle. This would be the easiest way to make the nozzle. With this material, the nozzle can be sculpted to the exact dimensions and have a smooth finish. Unfortunately, it remains unknown whether or not the material will be able to withstand the air pressure.

Combination Nozzle

As the name implies, this nozzle concept was born of two of the common types of nozzles, importing strengths and weaknesses of each. This nozzle will have a medium sized connector to the tube and a medium sized opening at the end of the nozzle (Figure 3).

However, since everything so far has been in between the extremes presented by the other two nozzles, it was decided to go the extra mile and reach a total equilibrium. The chokepoint will be located within the middle of the nozzle, thus providing a balanced alternative as opposed to the two specialized nozzle designs already conceived (Figure 3).

This nozzle design will be constructed from plastic. By utilizing pre-existing pieces of plastic, a shadetree mechanic can be made to operate as the convergent nozzle for this project. These pieces can be glued or perhaps even soldered together to form a cohesive solid entity. However, the creation of this nozzle will take some researching and scavenging to find the correct pieces needed for the design to be assembled.
