Travel Mug DESIGN Requirements

Principles and Elementsi)

Review the Visual Design PowerPoint on the shared drive.1.

Generate ideas: Draw a sketch or sketches of your best idea. You may use you current mug design from Inventor or make a new one.

2.

You may not have a principle of balance which uses shape/form. Since your mug is a revolved shape, it will automatically have a

balanced form.

i)

Write on your sketch where you include 2 of the 5 Design Principles [or one principle using two different elements] in your travel mug.

3.

Bring the sketch to me for signoff .4.

Save the sketch for handing in later.5.

You are on a design team that must submit plans for a product line consisting of travel mugs made from several materials. The container must

have a reasonable diameter and height to be stable.

A pressure fit lid which will be made as a separate part.

A handle attached to the body of the mug. The handle must be created with a spline and a sweep.

The mug must have:

The container must hold an even number of fluid ounces, between 12 and 30 oz. (plus/minus 0.3 oz.)

►

V = (Π r2 H)/1.804 oz./in3

You may use an alternate shape for the internal space, but you must be able to calculate and prove that you met the volume requirements

The inside space of the mug should be in the shape of a cylinder. All volume formulas must include the cubic inch to fluid ounce conversion factor

of 1.804 as illustrated below for the volume of a cylinder.

The ELEMENTS of Design The PRINCIPLES of Design

DESIGN is NO mistake! Products are created with an intent and purpose. Every product we own was designed with the core principles and elements of design in mind.

Look over the below PowerPoint.

Principles & Elements of Design PPT - Gives an explanation and example of each of the Principles AND ELEMENTS

ELEMENTS - The parts of a design that make it up. (Think of it as the Periodic Table of Elements - The Elements that make up our world) Elements are the building blocks of a design.

PRINCIPLES - Common ideas or concepts that make a design more appealing.

•

Copy/Paste the files (Train parts), I provide, from the Shared folder to your Student folder….in your TRAIN folder. Straight Track is 1 part you DO NOT have to build. Go get it from the Train Shared folder.

•

Your Train Working Drawing (C-size drawing sheet), when complete, needs to be saved as a PDF (*.pdf) to your Train folder. [Name your PDF file like this: SmithJ_p3_TrainCsheet.pdf]It must then be Copy/Pasted over to the Dropbox in the appropriate Period folder. Refer to the Class Notebook subpage to the left…Saving as a PDF

•

Important notes:Your drawing sheet should look like a photocopy of my drawing sheet when you are done. That's how identical yours should be to mine!

•

Color of parts (train body, peg, stack, etc.)

Letters associated with Section and Detail Views (A-A, B-B, etc.)

Numbers in the Balloons associated to parts (ex. My Stack may be a 5, while yours is a 2….that's OK) BUT, you must still have 6 parts total, numbered 1-6!

Ways in which your sheet CAN vary from my example:•

Clicked the wrong spot on a drawing when placing a dimensionOR

1.

Truly made the part file wrong. Go back and edit sketch or feature and fix the problem.2.

On your Drawing Sheet, if your dimensions come up as different numbers than mine, then you did 1 of 2 things wrong:

•

You DO NOT need the CURVED TRACK or the PIVOT at all.•

Copy/Paste the STRAIGHT TRACK from the TRAIN folder in the Shared folder.•

When Assembling the Train parts, you can stop when you hit the part in the Tutorial that says "You

have completed the assembly of the train." You do not need to move on to the Drive Constraints portion. Save your Assembly as "Train Assembly" and place it on your Working Drawing. Then bring the Assembly into a Presentation file (.ipn) and explode it.

Hydraulic Robotic Arm

From backyard log splitters to the huge machines you see on construction sites, hydraulic equipment is amazing in its strength and agility! On any construction site you see hydraulically operated machinery in the form of bulldozers, backhoes, shovels, loaders, fork lifts and cranes.

Hydraulics operate the control surfaces on any large airplane. You see hydraulics at car service centers lifting the cars so that mechanics can work underneath them, and many elevators are hydraulically operated using the same technique. Even the brakes in your car use hydraulics!

In this article, you will learn about the basic principles that hydraulic systems use to do their work, and then we'll examine several different pieces of hydraulic machinery found on a construction site. You will be amazed at the power and versatility available with hydraulics.

Pasted from <http://science.howstuffworks.com/transport/engines-equipment/hydraulic.htm>

Hydraulic: 1. the physical science and technology of the static

and dynamic behavior of fluids 2. the action of forces on bodiesRobot: a mechanical device for performing a task which might otherwise be done by a human.Pascal's Law: a change in pressure applied to an enclosed

incompressible fluid is transmitted undiminished to every portion of the fluid to the walls of its container.In other words, an incompressible fluid transmits pressure.Boyle's Law: a fixed amount of gas at a fixed temperature, the

pressure and the volume are inversely proportional.
