The Computer-Aided Design Technology

Design Project Competition 2006-2007

THE PURPOSE:

To have students experience the process of design from idea to implementation.

THE PROBLEM:

A recent high school graduate moves away from home to continue his/her education in college. After unpacking, and realizing they really do not have anything to do, he/she decides to make their first piece of furniture as they solo life. The idea hits him/her that if they were to take all the cardboard from the packaging used to move into their abode, they could make a pretty decent chair to see them through the school year.

The other thought that occurs to the new grad is that a cardboard chair would be environmentally friendly as cardboard is one of the most natural renewable resources known to man.

THE RULES:

Engineering Drawing students are to compete in this competition in accordance with the following rules.

1. Students are to design and model a cardboard chair within the parameters stated in the design problem below.

2. The design drawings and presentation drawings may be prepared by either manual or CAD methods.

3. The model must be constructed in materials as outlined under the Materials section of the contest guidelines.

4. All models are to be constructed within a space of 24"w X 24"d X 36"h.

5. The total cost of the model is not to exceed $50 and receipts for materials must be submitted with the entry.

6. The materials required to prepare the prototype chair portion of the contest should be found by asking retail and industrial establishments such as appliance stores, ACE HARDWARE, or the OGHS cafeteria.

7. Entry is to include both two-dimensional working drawings of the chair indicating bend, fold and cut lines as well as a three-dimensional presentation drawing of the chair assembled.

8. Design Solutions are due on the last regularly scheduled day of class.

9. The school is not responsible for entries and reserves the right to retain the winning entry for display purposes.

REQUIREMENTS:

The suggested order of procedure is as follows:

a. Research - see what others have done relative to similar contests

such as this using the Internet, library and local bookstores.

b. Design Sketches - prepare sketches of some possible design ideas of a chair of your own design.

c. Drawings - prepare dimensioned working drawings from your design sketches that will allow you to construct a model from the plans you prepare.

d. Model - prepare a prototype model made completely out of cardboard and fixatives as per the those allowed in this competition.

e. Test - conduct some tests to see how well your prototype conforms to the design requirements of this competition.

MATERIALS:

a. all forms of cardboard without metal or plastic reinforcement

b. all forms of glue fixatives

c. all forms of tape fixatives

d. no paints or finish materials

e. no metal fasteners

f. no string, rope or twine fastening materials

JUDGING:

* 25% = Function of the Chair (comfort) - subjective

* 25% = Form of the Chair (esthetics/appearance) - subjective

* 25% = Structural Integrity of the Chair (strength) - objective *

* 25% = Presentation of the Solution (drawings) - objective

# 5% = Bonus Points for Chair with Arms Added

* - Your weight divided by the weight of your chair equals a strength design factor. High numbers are best.

IMPORTANT DATES & DEADLINES!:

* Monday, November 26th - Assignment is given!

* Assignment is due the last day before Christmas Break!

CONTEST EXHIBIT:

We will put chairs in the Display case by the restrooms for the entire school to see.
