Solving Problems and Making Ideas come to Life
Results:
Throughout the course of design portion of the design project, there were two major design concepts that were created and design variation that occurred between the two of them. Ultimately one design for the peg was chosen and had multiple design evolutions applied to it. The first design evolution was varying the thicknesses of the walls of the peg. Varying thickness was chosen between 0.10 inches and 0.375 inches. Upon Solidworks modeling design, it was determined that anything above 0.25 inches would not work in terms of fitment for some parts such as the main shaft as well as weight reduction. Having thicker walls added more weight than was necessary for the pegs to have. Thickness modifications also came into play with where the shaft connects through the one side of the peg. A thicker wall was necessary there to for more support for that structure with an extrusion coming through the middle of t which would weaken that wall leaving it 0.10 inches like the other walls.
The second design evolution came with the design of the pivoting mechanism. With updating the thicknesses of the walls, the shaft length and diameters were even more crucial to fit within the confines of the peg. Different size shafts were modeled in Solidworks and tested within an assembly with the peg to ensure proper fitment and clearance for proper operation of the overall project.
Project Risk Analysis:
The risks that the project can endure are costs, manufacturability, and time. Timing risk can affect all aspects of the project. If a piece of material doesn’t show up on time or the time it takes to machine a certain part takes longer than expected, it can affect other areas of the project where you may need to cut time form to make everything work which deteriorates overall project performance and design. If the manufacturability is not conducted to the highest of tolerances or production, the overall design will not be as structurally sound as it was designed to be. .If the overall project that gets constructed is not up to the full potential, it can become dangerous for the rider if the project were to fail while attempting a large jump or obstacle and causing raised potential of a painful crash.
Next Phase:
The next batches of possible designs of a pivoting mechanism and peg have already been considered. Upon completion of this design project, possible design flaws and improvements will be discussed and documented for design improvement and implications into future designs. Design improvements or innovations such as wall thicknesses or geometry will be considered and analyzed to determine how they would affect the overall performance of the project. Third party members with similar interest will be gathered to gain additional insight on further developing the concept.
