My First Blog Post!

Hello every one!

This is my engineering blog, welcome.

This is the the logo for the Coronado lacrosse team which I am a part of.

Final

1. Define the problem:

• The problem is there is no good way to store a bike inside a college dorm room.

2. Brainstorm solutions:

• Put hooks on the wall to hang it from.



• Put hooks on the ceiling to hang it from.



• Have single bike rack that can raise up like on buses.

3. Define criteria and constraints:

• No permanant damage



• Must save space in a little room



• Must fit a full sized bike



• Easy to assemble

4. Sketches:






5. Select an approach: usea decision matrix to justify your approach:




6. Model your solution with CAD software: post an isometric view of your assembly and a multi-view drawing:
7. Use the four quadrant feedback technique to assess your model:

Glider CAD Model

Glider Designs

DESIGN PHASE

1) whats the challenge?

To design a glider.

2) brainstorm your solutions

IDEAS: a lot of surface area of wings, biplane design, vertical tail wing.

3) Constaints-

Had to use the supplied paper and balsa wood, can use tape or glue to hold together.

TEST PHASE

DESIRABLE OUTCOMES:

• The glider has very good lift


• The glider is very light

OUTCOMES TO CHANGE:

• Slightly pulls to the right


• Pulls up then stalls if not thrown hard

QUESTIONS RAISED:

• How to fix the pull to the right


• How to make it go faster

IDEAS GENERATED:

• Add more wieght to keep from pulling up


• Put a stabalizing wing to keep from drifting right

Iteration #1

JUSTIFICATION IN RED

ACHIEVEMENTS EARNED: 15

Idea Generation Achievements-

• Sketch of one possible solution


• Generate a list of achievements for build day


• Document a plan to ensure materials are brought in on block day

Build Achievements-

Material Size-

• Your material fits inside a printer paper box


• Your material fits inside a shoe box

Our design was small enough to fit inside the shoe box.

Material Weight-

• Your materials weigh less than 500 grams


• Your materials weigh less than 300 grams


• Your materials weigh less than 200 grams


• Your materials weigh less than 150 grams


• Your materials weigh less than 100 grams


• Your materials weigh less than 50 grams

Our design weighed 49 grams.

Drop Achievements-

Drop Accuracy-

• NONE

Our egg broke before we dropped it.

Egg Resilience-

• Your egg broke but the yolk remained intact


• Your egg cracked but the yolk remained inside and intact


• Your egg cracked but was still together

Our egg was only cracked.

Calculation Achievements-

• NONE

We didn't use any math with our design.

Other Achievements-

• Help set up the bulls eye

Fred and i set up the bulls eye on drop day.

The designs that seemed to work best for my class were the ones that were very simple, light, and had a lot of padding around the egg.

If i were to redesign my solutions, I would use less rubber bands and more cotton balls because the rubber bands put to much pressure on the egg.

TED pt I - Ideas worth Spreading?

1) The TED organization is about letting people speak about the ideas they have on different and important subjects.

2) The purpose of their website is to let people that were not invited to the TED convention can still learn about these new ideas through watching videos.

3) I believe the science , technology and design topics are the most important because all of those have an equal influence on you develop a product in engineering.

4) A: "Are We Born To Run" because it opens up alot of new design possibilities.

B: "Eythor Bender Demos Human Exoskeletons" because it shows the huge advances in technology and the possiblity for more.

5)

6) Theres not really a field to gety involved with, but something I can do to experience what McDougall is talking about is to read his book and try running bare foot for a while.

Reverse Engineering: Mechanicnal Product - Functional Analysis

1. What is the purpose or primary function of the object?
To read a game and project the visual and sound on the screen.

2. Make an educated guess as to how this product operates. Use simple machines’ terminology to explain the object’s sequential operation.
there is a light bulb to produce the visual, a speaker to produce the sound and a small computer chip to read the information on the games.

3. Identify the system inputs, intended product function, and outputs. Use power point to create a "black box" graphic like the toothbrush example discussed in class. Save the slide as a .jpg image and post it to answer this question.
AT TOP

4. What mechanical components are visible?
the only visible part is the screen where the light is being produced.

5. What is it about this device’s function that you cannot identify, because the mechanical components are hidden from plain view?
I can not identify how it makes a vibration because it is covered by the plastic shell.

op in: less is more

The New balance 890 is an elegant shoe for a many different reasons:

• It has a very light weight design that allows for less fabric to be use
• Its over all design is very sleek which gives it less wind resistence.
• The grip is very basic but very effective because it is put together in big pieces of the same grip rather that many small pieces of different grips

The New Balance design team used most of the 12 step process.

• They identified the problem
• they thought of new ideas for that problem
• they brainstormed designs
• came up with a model and tested it
• redesigned the model for better preformance
• finally the tested their final product and sumitted it to New Balance

Graphic Design: What's Going On In This Design?

This is an advertisment for a carbon fiber Ferrari.



It came from Classic and Sports Cars Magazine.





The article is pretty easy and clear to read.


the size of the article is not to long and it gets right to the point.


the message stays on topic and only talks about the product.






1. What are the trends? Why is it important to identify them prior to graphic design?
trends are the things that people are into at that time. you need to know them so you can design somthing that fallows those trends.




2. How does human nature play a role in how a product is marketed to a specific demographic group?humna nature plays a very big role because humans decide things based on how they feel about the product.

3. how is a potential audience identified?

they can be identified threw many different ways, commercials, adds, surveys.

4. what must you discover about the target audience prior to graphic design?

you must discover the trends of ur target audience and find what they are into.
