Group Corrugated Board Chair Project

By: August, Evie, Iris, and Swaranjali

Goal:

Inspiration (for each member's designs):

To combine the designs of each group member's chairs to accomplish the following:

build a chair that can hold a human adult (target = 180 pounds)
we can use only 2 sheets of corrugated board (48 x 96in)
it must be aesthetically pleasing
it must be comfortable
it must be portable

Our Sketch:

(drawn by me)

To create this design, we wanted to combine our favorite aspect of each group member's chairs. We decided to incorporate the supports and framework of my chair, the curved shape of August and Swaranjali's chair, and the low height of Evie's chair. We did this by creating a side panel that was shorter, making the edges curved instead of 90 degrees, and adding panels with slots. We also utilized the same supports used in my initial design.

Mini Model (created by me):

After August created and printed out the IDW of the flat patterns of our design, I glued the paper onto scrap cereal box material and created a mini model of our design accordingly. This made me realize that the length of the outer pieces should be increased, to ensure that the chair will assemble easily.

Bringing our design to life:

STEP 1 - SKETCHING OUR DESIGN

First, we transferred our design onto our two corrugated board sheets by using rulers and protractors to measure the lines and angles as they were in our digital design.

STEP 2 - CUTTING OUT OUR PIECES

Next, we learned how to use a jigsaw to cut out our pieces. Once we had our individual parts cut out, we learned how to use the bandsaw to make our precise notches in the side panels.

STEP 3 - CREASING OUR PIECES

After cutting our pieces, we utilized rollers to create creases in these pieces to make folds. For the curves, we made a row of creases in roughly one-centimeter increments.

STEP 4 - PROBLEM SOLVING

After assembling our chair for the first time, we hit a couple major problems. We needed to add more support to the seat of the chair as well as fix a piece that did not fit properly. How we tackled these issues is explained in the video at the top of this page.

STEP 5 - TAPING

Finally, we utilized white tape to make the edges of each appear neater. We later added tape to the border of our two side pieces, which made the pieces fit more snugly.
