Week 5: Manual and CAD drawing

Recap from last blog, my team and I came up with the SCAMPER, feasibility analysis and COWs for a air-con. However, after much deliberation with the team, we decided to change our chemical product to a jar opener.

Now to officially start off this blog. First we were introduced to drawing from a 1 point and 2 point perspective.

Now moving on to CAD, which stands for Computer Aided Design. This is where we learn how to sketch in 3D using Fusion 360. The first task is to create a keyring. Although navigating through Fusion 360 was difficult, the outcome of the product was worth it!

After making the keychain, I made a photoframe.

Personal takeaways and learning reflection
Before this lesson, I did not enjoy sketching as I find it lame and very uninteresting. But after this lesson, I started to enjoying drawing. Starting with 1 point perspective, then 2 point perspective, I started getting the hang of sketching and getting confident in my sketches.

When I was introduced to Fusion 360, I was so lost with the controls and had a tough time navigating through the app. However with the step by step instruction from Dr. Noel, I started getting the hang it and was eventually able to create a keyring and a photoframe.    

Practical 2: Cardboard Joinery

Starting off this section, Dr, Noel grouped us again in random groups. My group consist of me, Ethan, Sailesh, Isabella and Weiling. This practical requires us to create a cardboard model which consist of 5 different types of joinery which includes L-brace, flange slot and tab etc.

Figure 7: Different Joinery

Before the practical, we were required to do a literature report on cardboard and brainstorm with the team on how to implement 6 different joinery into our cardboard model that we are going to make.

When I was doing the literature review, I realised that there many different types of material and flutes that are use to make a cardboard

After brainstorming for ideas, the group eventually came up with the idea to create a monster which takes the form of a chest.

The materials that were given to us includes:
  1. Cardboard
  2. Cutting board
  3. Scissors
  4. Penknife
  5. Rulers
  6. Brass Fasteners
  7. Tape
Firstly, we measure and drew the dimensions of the different parts of the model on to the cardboard.



We then cut out the different parts of model from the cardboard.


Finally we joined the different parts with different tape and different types of joinery.


Eventually we created our own cardboard model!!!!!!


The 6 different types of joinery in final cardboard model are:
  1. L-brace
  2. Tabs
  3. Slot
  4. Slot and tab
  5. Holes with brass fasteners
  6. Wires
All in all, the team worked really well together and was very happy with the outcome of the cardboard model. 
Some key takeaways was that we have work with the limited resources provided for us and learn how to share the tools with one another.
