Final Challenge

The Problem: Bikes take up a lot of space and we need to design something that will allow you to lock your bike in your house without taking up that much space.





Brainstorm: A ring that can suction to the wall

A hook on the cieling so you can store the bike on the ceiling
A heavy concrete block with a ring on it


Criteria: Easy to assemble, Stores a bike, Small



Constraints: No permanent damage, Has to be small



Sketches:



Approach: I decided to use the concrete block idea because it is very secure




Finished product:









4 quadrant feedback:

Glider Challenge




1) What's the challenge? - the challenge that were were given was to design a glider that flies the farthest and has the most hangtime. 2) Brainstorm solutions: -What are the rules of brainstorming? (oxymoron) - my group and i needed to keep in mind that we are gunna have a list of material that we have. -List your ideas - build a plane designed for gliding not speed -Sketch at least two of them 3) Specify: -Criteria - the glider should fly - have fair amout of hang time -Constraints (be specific about materials available) - we were to be givin 5 pieces of very thin balsa wood and a 2 by 2 piece of tissue paper to construct our wings. 4) Develop Solutions: -Sketch (with labels) -Model in CAD 3) Your Glider Challenge: Test Phase notes. 4) Your Glider Challenge competition day results. How did your glider perform? What would you change if we competed again? - our glider won the loingest distance challenge, but preformd poorly when we attempted to get the acheivment of longest hangtime. if we were to rredesign the plane we would take of weight on the nose and widen the wings to increase hangtime.

    TED pt I - Ideas worth Spreading?




    • TED is a nonprofit organization that has talks about lots of different topics. TED stands for Technology, Entertainment, and Design. TED also has conferences in the US every spring.
    • The purpose of TED is to "spread ideas worth spreading". The site has lots of videos in different topics. The site is really functional because the videos are put into categories.
    • I think the two most relevant topics to our class are technology and science. Both these topics have a lot to do with engineering. The other category that is kind of relevant to our class is design, because our class is called engineering design.
    • The video "reengineering the brain" has a lot to do with engineering. The video "i built a toaster from scratch" has a lot to do with are class because a big part of engineering is building things. "Using nature's genius in architecture" has a lot to do with our visual design elements and principles.
    • This talk is about reengineering the brain to do certain things. He shows how the brain works and how different things effect your decisions and the way you think.
    • The fields that would have things to do with this talk are biotechnology and neurology. If i wanted to get into this field i would need to take a lot of biology and some psycology. I would probably have to major in neuro science in college if i wanted to pursue a job in this field.

    Reverse Engineering: Mechanicnal Product - Functional Analysis

    1. What is the purpose or primary function of the object?

    The primary function of the calculator is to do math.

    2. Make an educated guess as to how this product operates. Use simple machines’ terminology to explain the object’s sequential operation.

    When you press the buttons the corresponding character shows up on the screen. When you input an equation inot the computer the calculator uses guess and check to get the answer.

    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.



    4. What mechanical components are visible?

    The buttons are the only mechanical components.


    5. What is it about this device’s function that you cannot identify, because the mechanical components are hidden from plain view?


    I cannot identify how the electrical stuff works. All i know is that the buttons are connected to wires that make different characters show up on the screen.

    Reverse Engineering: Mechanical Product - Visual Analysis

    TI-89 Calculator

    FRONT TOP SIDE


    Analysis: The calculator uses lots of curved lines. The bottom half of the buttons have vertical symmetry. It has a smooth texture. Different colored buttons are colored for emphasis because they are important buttons.




    Functional: The calculator is used to do mathematical equations. The buttons are used to type in different characters and symbols. The screen shows what you are inputting into the computer.


    Audience: The target audience for this product is students in advanced mathematics classes. It can do simple things too, but there is no point in buying the calculator unless you need to use it for advanced mathematics.
