2.5 - Puzzle Cube Design

Problem Statement

A local office furniture manufacturing company, Tetris Furniture Inc., throws away tens of thousands of scrap ¾” hardwood cubes that result from its furniture construction processes. The material is expensive, and the scrap represents a sizeable loss of profit.

Design Statement

Tetris Furniture Inc. would like to return value to its waste product by using it as the raw material for desktop novelty items that will be sold on the showroom floor. Design, build, test, document, and present a three-dimensional puzzle system that is made from the scrap hardwood cubes. The puzzle system must provide an appropriate degree of challenge to high school students.

Part 1 - Cube Design

In this activity you will document alternate designs with pictorial sketches and specify your final puzzle cube design.

Equipment

Snap Cubes
Puzzle Cube Design Sheet
Color Pencils

Procedure

Create a puzzle cube design. All Puzzle parts must meet the following criteria:
1. There must be a total of 5 Unique parts that assemble to make the cube. (Mirrored parts are ok)
2. Use 4-6 Cubes per Part.
3. All parts must extrude in all 3 directions by more than 1 block. (No Flat Pieces.)
Neatly sketch and color code an isometric view of each of the five component parts and show how they fit together in the isometric view of the cube using the Puzzle Cube Design Sheet.
Take Pictures of the design sheet and both your Assembled Snap Cube Design and individual parts (as shown below) .

Rubric:

E111.03 - I can design and develop prototypes including, machines, structures, and electromechanical devices, and Electronics using technology resources that demonstrate and communicate curriculum concepts.

4: Excelling

I have have created a prototype design for the puzzle cube that meets all design criteria that is documented in the design brief. I have documented this design through photos of the snap cubes and the colored design sheet.

3: Proficient

I have have created a prototype design for the puzzle cube that meets all design criteria. I have documented this design through photos of the snap cubes and the colored design sheet.

2: Developing

I have created a prototype design but I am either missing documentation or it does not meet all of the design criteria.

1: Emerging

Anything less than 2.

Part 2 - Multiview Drawings

Now document the 5 pieces of your chosen puzzle cube design by creating an Isometric and multi-view drawing for each piece.

Equipment

Ortho w Iso Corner
Ruler or straight edge
Pencil
Computer with Internet access

Procedure

On orthographic with Isometric grid paper, create an Isometric and multi-view drawing of each of your five puzzle pieces for the selected design. Use the U3.3b - Ortho w Iso Corner.PDF to create your sketches on. Make sure to use 3 grid squares per .75" as a scale for your drawings.

- - Carefully select the best front view
  - Include all object and hidden lines.
  - Show Front, Top and Right view of each part.
  - Do not show the joints between individual cubes unless there is a level change.
  - Dimension your drawing following the Dimensioning Guidelines. 2.4 - DimensioningGuidelines

Have your teacher verify your first drawing before you do all 5.

Post your drawings to your Engineering notebook

Rubric:

E114.ME01 - I can understand, interpret, and create Technical Drawings/Sketches.

4: Excelling

I have created mechanical drawings (Iso/Multiview) of all 5 parts of the puzzle. I have neatly drawn the isometric view of all shapes in the proper orientation with the proper shading. The multiview drawings have the correct orientation , and alignment with proper object and hidden lines captured in each view. I have properly dimensioned the drawings. with no more than 4 line/dimension issues across the 5 drawings.

3: Proficient

2: Developing

I have created mechanical drawings (Iso/Multiview) of all 5 parts of the puzzle. I have neatly drawn the isometric view of all shapes in the proper orientation with the proper shading. There are some issues with the orientation or alignment of the multiview drawings or there are more than 8 line/dimension issues across the 5 drawings.

1: Emerging

Anything less than 2.

Part 3 - Wooden Prototype

In this activity you will build a prototype of your puzzle cube with wooden blocks.

Equipment

27 wooden blocks
Glue
Sand paper
Markers
Design documentation

Procedure

- Sand the end grains of each block
- Use glue and a friction joint to glue the blocks together. (Don’t get glue on the table!)
- Create all 5 parts to your puzzle cube.
- Use Markers to color each part.
- Verify that all the parts fit together before it dries.
- Take pictures and put them in your Engineering Notebook.
- Test your design by having different people solve your puzzle cube and time how long it takes

Once compete, take pictures and put them in your Engineering Notebook then test your design by having different people solve your puzzle cube and time how long it takes.

4: Excelling

I have created a wooden prototype that fits together and matches the intended design. It is properly colored and meets all of the design constraints. I have evaluated my final prototype and captured the evaluation in my engineering notebook.

3: Proficient

I have created a wooden prototype that fits together and matches the intended design. It is properly colored and meets all of the design constraints.

2: Developing

I have created a wooden prototype that fits together and matches the intended design.

1: Emerging

I have created a wooden prototype that does not fit together or is missing pieces, or it is a paper weight.
