Puzzle Cube Project

Project Description: Design a wooden puzzle cube that is 3x3x3 cubes

Criteria:                                                                                                               
-Design and create a wooden puzzle cube

Constraints:
-Must have 5 pieces, composed of 6 or less blocks
-A piece may only be duplicated once 
-Total of 27 blocks in the puzzle, each with a measurement of ¾”cubic    units
-The completed puzzle should be 2¼” x 2¼” x 2½”
​-Must interlock (contain pieces in x,y, and z axis)

Students sketched and created orthographic drawing for each puzzle piece.

Using Autodesk Inventor, students created online orthographic drawings for each piece. 

The screenshot below displays the assembly of all of the puzzle pieces to form one cube. The table in the upper left corner demonstrates the order of assembly of the cube.

Parametric Construction: Chess Set Project

Project Description: Design a chess set on Autodesk inventor. Each group member will only make one piece.

-Design a chess set with the standard pieces in three sizes:                     -Designed with only parametric function constraints
  normal for home, small for travel and large for outside                            -The set must contain: 2 Kings, 2 Queens, 4 Bishops, 4 Knights, and 4            
-Use parametric functions constraints                                                            Rooks
-Choose a theme for the chess set                                                                 -Each piece must contain at least two advanced features   
                                                                                                                              -Must derive one, uniform base onto each piece

Group theme: Superheroes
My piece: The rook, Iron Man

Automata Project

Criteria:                                                                                                                        Constraints:
-Design an automata with at least one crank, axle, cam,                                     -Volume for frame must be:    6 – 12” long
 follower, and one figure                                                                                                                                                 4 – 6” high
-Must use standard size materials                                                                                                                               4 – 6” deep
-Use polar grids and motion graphs to design a cam                                          -All material 3/8” minimum thickness
                                                                                                                                      -Crank and axle are to be 1/4” DIA
                                                                                                                                      -Cam with a minimum 1/4“ thickness
                                                                                                                                      -Follower with a minimum 3/16” DIA

A cam is a mechanism placed inside of a product to cause another item to move or change a figure’s direction. 

After assembling the separate parts, students took apart the design to show the process in assembling all of the parts.

Reverse Engineering Project

Project Description: Reverse engineering is the process of disassembling an object that completes a function, understanding the functions of the product, and then designing changes to improve the functionality of the item. Students worked in groups of 2-4 as a team to take apart an object. After disassembly, they completed a visual and functional analysis of the product of choice. They were were to draw orthographic drawing rough drafts of the individual pieces that make up the item. They would create the parts on inventor, splitting up the duties of each part, to practice working in groups and referring back to each other to match up dimensions.

The sketch below the original rough draft orthographic drawing for the black lid ring of the flashlight. 

The screenshot shows the final orthographic drawing on Autodesk Inventor for the black lid ring of the flashlight.

The screenshot below shows the product assembly.

To better the design of a flashlight: If the product could be revised, fewer parts in the design would make it less likely to lose the smaller parts. Also, all of the little parts make it easier for flashlight parts to be broken.

Final Design Project

Project Description: Students used the design process to create a product that fixes a justified problem that they researched. 

Problem Pursued: Automobile drivers and passengers that wear seat belts in the United States have complained that the belt and buckle can become too hot to touch at over 36.8°C when the car has been exposed to the sun and heat for over 15 minutes. Seat belts became mandatory to wear in the 1970s. According to a survey in Severna Park, MD, 71.72% of people said they have had experiences in which the lap strap was too hot to touch. Additionally, 96.0% of people have experienced situations in which the metal tongue of the buckle was too hot to touch. The heat absorbed can be attributed to the material and color used to make the strap and the buckle material being made of metal, a heat conductor.

Research:
The problem was validated through the creation of a survey: https://www.surveymonkey.com/collect/?sm=7BF81IlWY3AGy52HvSx QG7MLQDV3                                                                                                              vVR20tb3Vyi_2B Us3MS QBIXI4gn1NrYAMnn2A

Data Analysis (of those who took the survey):
-98.87% have gotten into a car that was very hot on the inside
-71.72% said the strap of the seat belt has been too hot to the touch
-96% said the metal tongue of the seat belt buckle has been too hot to touch
-46% have burnt their hand or chest when wearing a seat belt
-49% know others that have burnt themselves on a seat belt before
-3% said that their seatbelts have never been too hot to touch
-81% said they would definitely or maybe buy a product to prevent seat belts from getting too hot

The solution: Ice Ice Belty
