- Cardboard Chairs:
- Project Outline: In our cardboard design we decided to build a little kids chair for our teachers kid. We built chairs only out of cardboard. We also made our dimensions off of his kids favorite chair.
- Guidelines
- 1. Single piece of cardboard
- 2. Not able to use anything but cardboard
- 3. we have a maximum of 64 square feet of cardboard that we can use
- 4. The thickness of the cardboard has to be 1/4 of an inch or less
- Key Concepts:
- 1. Tensile strength
- 2. Compressive strength
- 3. Center of gravity
- 4. Structure
- Function:
- All the chair's dimensions are appropriate for a person to sit in comfortably.
- Structure:
- The seat can support a person whose weight is anywhere on the chair. The seat & If the chair has a back it needs to support a great amount of weight and force.
- Aesthetics:
- We needed to create a design that could support deferent peoples tastes and styles.
- Economy:
- The chair's design is considered to maximize its strength, function, aesthetic qualities while using the least amount of material practical to do its intended job. All decisions regarding economic use of material are justified. We as a group decided that we would give up economy for function and aesthetics.
- Integrity:
- An honest effort to complete the work and make the best possible chair is evident. The particular value of making chairs from cardboard, or lack of value was considered.
- Making Trade-Offs:
- Serious weight was given to each of the five design criteria (above) in regard to meeting or exceeding the Challenge's specifics. For example, 'We tried to reduce material use purely to save material. We considered sacrificing strength for aesthetic reasons. As a group we only made one trade off which was economy for strength and aesthetics.
- Decision Making:
- Decisions were made only when evidence or their impact was presented and evaluated. Test data was collected and considered when possible. When we made our decisions we did so as a group to get all input and the best designs.
- Group Process:
- Our chair was very well thought out and we executed it very well. Our chair can support way more than 75 pounds. Our first chair was a total failure but we learned and were able to create a way better version. We worked well as a group. I learned that i needed to be exact and plan it out before I make it. I also learned that I need to slow down and make sure everything is going well.
