Week 13B

 Hello again! For this week's practical our group had to make joineries using cardboard.

Part 1

During the first part of the practical, we were introduced to different joineries that can be made with a cardboard. This include score and bend, slots, gusset and flange. An example can be shown below:

After being introduced to the joineries, we were tasked to make up a product that is made up of at least 6 different joineries. During the planning process, we thought of making a tank and that was what we did. Here are pictures of the fun building process:

The different joinery techniques in the tank include the slots and tabs, slots, score and bend, slits, gussets, layering and more. Here is the final product:

Overall, it was a very fun practical where we get to learn many different joinery techniques using cardboards. In the future, we are able to use this knowledge about joinery techniques when making prototypes.

PART 2

After learning the different ways on how to join carboard together, we were given a simple task of assembling a paper unicorn as shown below! 

 

Despite the unicorn looking really simple, it was slightly challenging due to some of the parts being really flimsy and easy to tear. Hence, it was necessary to construct the unicorn carefully and delicately, otherwise there might be damage to the unicorn. 

After the basic task of constructing the unicorn, we were tasked to make the unicorn wings flap. After examining the design of or unicorn, we realized that under the belly of the unicorn, there was 2 flaps connecting the unicorn’s wings. With that flap, we attached a rubber band to the flaps of the wings in the belly. That way, both wings will flap when a motion is applied to the wings. 

PART 3

For automation of the flapping of the unicorn's wings, one way is to use a rubber band that is attached to both the unicorn's wings, which is then attached to a small stick attached to a rotary wheel.

When the wheel is turned, the stick will pull on the rubber band which would pull the wings forward, and one full cycle would result in a full forward-and-backward of the unicorn's wings.
