Your five parts must have a total of 27 cubes for your

puzzle to work.

No part can be more than 3 cubes long in any direction.

Your sketch needs to remind you how the pieces will go

together.

Put your name on the sketch in case you lose it.

Now that you have a design, its time to test if it will work.

We will use the Inventor software to simulate the shapes of our cube puzzle parts. Then we will put the pieces together in Inventor to make sure everything fits.

Open a Part file.a)

You will use wooden cubes to eventually build your cube puzzle to take home. The cubes we need to model in Inventor are 0.75 inches on a side [2 cubes = 1.5

inches, 3 cubes = 2.25 inches].

b)

Each puzzle piece is a separate Inventor Part file. Each Piece should be made a different color.

c)

Save each of your Parts in the R:\\ drive in your folder. d)

Making parts in Inventor

Once you have made all five of your parts in Inventor:

You may open an assembly file, place your component parts in the file, and 3D constrain them together using mate and flush. For more assistance,

open the Inventor help screen [Get Started tab /Help], and search for any of the words underlined in bold letters.

1.

Open an assembly file and Place Components until you have your five parts.

Collect your cube parts in one assembly file:

Constrain your part to the assembly. Use some combination of threemate or flush constraints for each part.

Each part will need to be attached to other parts in the assembly.

When a part is completely constrained to the cube assembly, it shouldn’t move.

Finish constraining one part before you move on to another.

Assembling the cube:

If you have extra time, edit your cube puzzle parts to have 5 interlocking (complex) pieces and color each part differently.

Assembling parts

Each Piece should be made a different color.

All side dimensions must be a multiple of 0.75 inches [2 cubes = 1.5 inches, 3 cubes =

2.25 inches].

The "Fragrance Is Good" Bottle Design

Narrative:

As a newly hired designer, you have been chosen to create a new bottle design for the Fragrance Is Good company. Fragrance Is Good is unveiling two new fragrances, one a men’s and the other a women’s scent. The company needs a bottle design and name for its new fragrance. You must create both a man's and a woman's fragrance jar, including a name for your fragrances. You may not use an existing logo or design.

Create the new bottle shape and name.

Design Statement:

Design must have 2 Principles of Design included [Design Principles & Elements]

1.

Jar must have a removable cap.2.

Use loft, sweep, revolve or a combination (You may use extrude on other parts of your design), Or

A.

Extrude a complex 2-dimensional sketch (you can't have a cube, cylinder, etc.).

B.

The bottle (part holding fluid) must be a complex shape. Either:3.

Holds between 3 –7 ounces of fragrance.4.

Bottle cannot be taller than 8 inches.5.

Bottle cannot be larger than 5 inches in diameter.6.

Each bottle must have a decal or emboss of the name or image of the fragrance on the bottle.

Volume of an Inventor shapeWednesday, December 12, 2012 11:48 AM

Assignments Page 44

Check Iproperties volume; 4.

This tells you how much material it would take to

make the shape.

Convert to ounces [or just divide by 2 to get an

approximation].

5.

If its too big or small, adjust size and repeat until your

design is within specification.

5. If you're close, you should use the exact conversion factor [1.802] for cubic inches to ounces.

Then you may shell your jar to the outside, and finish

adding all other details.

6.

By shelling to the outside, we set the empty space inside our

shell to be the same as the volume we checked in step 4.

Assignments Page 45

Use the A-size sheet.

Follow all dimension rules, don't just imitate the example sheet.

The front view of the bottle should show the emboss or decal of the bottle.

The side view of the orthographic should be replaced with a section view.

The bottle top does not need a section view.

Dimension the thickness of your shell if you can.

You may use any scale you wish, just be sure the parts are clearly visible.

#2 Floatation Does it fall over or lean to one side? •

#3 Buoyancy

Can it hold the weight of the engine components?

Is there freeboard? Remember, boats need to be open.

Test motor parts piled in the boat, NOT placed.

them.

Can the prop spin without hitting the boat or the water?

Test motor parts in design positions •

After enclosing the foamcore ribs of your boat with duct tape, perform the following tests, in order. Your boat must pass one test before you go on to

the next.

Do not leave test motor parts

on your test boats !

You may modify your hull using scrap foam core and duct tape to get an idea of how to improve your

Research, design, build, test and race a boat:•

Design Constraints

The boat must be stable enough to safely hold the components of the propulsion system when racing against other boats.

1.

The boat must reach the end of the challenge basin within a specified time frame [to be specified later].

2.

Hulls must allow visual and physical access to the inside of the main hull of the boat. The part of the boat that supports the

motor parts must be open.

3.

Total width = 6.5" [includes hull, pontoons, etc.]

Individual part width= 5"

Length = 8.0"

Draft = 2.5"

Maximum Allowable dimensions4.

Maximum thickness of boat shell and keel pieces = 0.10"

Cutting Width = the dimension of your "slice" when making ribs

Same dimension restrictions apply even if the shelling method is not used to hollow the hull.

0.075" < Cutting Width < 0.15"

Usually its the stern rib, but it can be any part.

Must be "flat." Flat = no higher than 0.15 inches when laid down

Only one non-hollow piece will be 3D printed:

Ribs and Keel:5.

Any parts that touch the water must be made in the 3D printer and meet all the above requirements.

6.

Excessive amounts of glue or tape will not be permitted.

Only materials or parts from LHS will be permitted (e.g., can't use your own batteries.

Any dimensions, values or calculations need only be accurate to one decimal place [xxx.x].

As a minimum, you need to assign a material property for the batteries and the motor.

To calculate density, you need the volume and the weight (mass) of the part.

<file://R:\ProjectLeadTheWay\Share\Snider\DDP Honors\Finding Density.doc>◊

Volume [cubic inches]

Determining Mass, Volume and Density

Finding DensityMonday, May 10, 2010 8:46 AM

Assignments Page 133

Research on the internet to find the number of cubic centimeters in one cubic inch (hint: it's greater than one). The factor only needs to be

accurate to one decimal place [xxx.x].

◊

Conversion Factor

Multiply the Inventor volume by the conversion factor.◊

Volume [cubic cm.]

◊

Request the electronic balance from Mr. Snider.

Weigh your part in grams.

Weight

Mass◊

= weight/volume [grams/cubic centimeter].

Divide the weight you measured on the balance by the volume in cubic centimeters.

Density◊

In Inventor iProperties, find a material that nearly matches the density and assign that material to the parts [battery and motor].

Assign a material to your motor and battery parts◊

Assignments Page 134

Tolerance should be within 10-20 %. For example, if your calculated density is 10 g/cm3, a value of 8 g/cm3 should work ok.

The battery case, motor clamp and anything from the 3D printer can be assumed to be ABS plastic. You do not need to assign a

property to the propeller.

For any foamcore parts, find a material with a density less than 1.0 g/cm3. That's the density of water, and we know foamcore is

less dense because it floats.

Don't forget to assign a material to the rest of your boat parts as well!

Assignments Page 135

Be sure the material of the motor, batteries and all other boat parts is properly assigned [see Assign a material to your motor and battery

parts].

Remember that your components have to be accessible, as well.

Experiment with placement of your components. 4th.

Note: All components must be returned to me at the end of the project. You may not glue them in place. Also, they should be

easily detachable in case you need to replace a faulty component.
