Week 13 (P3)

CP5065 Week 13 Report DCHE 2A/01 Group 1 Garage Engineers
Introduction

In week 13, for our ICPD lab, we learnt about the different kinds of joinery at the FabLab at T11C. The lesson taught us how to make the different kinds of joinery that we can use, to hold and strengthen our cardboard in order to make strong and durable cardboard sculptures etc. For example, we had to follow a visual board created by the lecturers and try to replicate it to the best of our abilities (Fig 1). After the first assignment, we were given about 2 hours to create whatever we like using cardboard. However, we had to include the joineries that we learnt. For our group, we created a “McDonald’s Meal” (Fig 2), while the other groups created a Helicopter etc.


Pre-session preparation: Short notes on corrugated cardboard

Corrugated cardboard is commonly found in our daily lives. It consists of three layers where there is a piece of a corrugated material which has an inner and outer layer of paper liners. All 3 layers of paper are assembled in a way that they create an overall structure that is robust. Those liners are commonly Kraft and Test Liners. They are the strongest type of paper and are easiest to print. An additional liner may be added to make the cardboard more rigid and can withstand heavier items or protect fragile items from impact. Furthermore, The connected arches are ideal for bearing heavy loads, while the air circulating in the flutes acts as an insulator, offering further protection from temperature variations. Additionally, corrugated cardboard has many benefits. For example, it is durable, lightweight and has a high strength to weight ratio. It is also cost effective.

Drink The drink is made by using score and bend to make it into a cylindrical shape to create the cup of the drink. As for the lemon at the side of the cup, we have cut a small slit on the lemon to create a slot for the lemon to stick onto the cup.

Fries
For the fries, we have added the gusset at the back of the box in order to support the weight of the fries and prevent it from toppling over as it is slightly slanted. We have also placed a tab at the side of the fries box to support and put the box securely and in place.

Burger
As for the burger, we have added a ‘flag’ onto the burger which holds the layers into one for a real burger. For the flag, we have added a flange to make the flag upright while it is securely attached to the burger. We have also added a rotating part to the flag to mimic a real flag that would sway reacting to wind.

  ACTIVITY  2   Chemical Product Life Cycle    Chemical Product : Portable Water Heater     1) Extraction      Since our product is a portable water heater, commonly used materials required are copper and stainless steel.  Copper is obtained by  ore that is removed from the ground in either open pit or underground  mines. Stainless steel is  consisting  of  raw materials of nickel, iron ore, chromium, silicon, molybdenum, and others, are melted together.   2)  Manufacturing & P roduction   “ Manufacturing”  refers to the making of products  in factories by machineries   on  a large  scale . This process change s individual pieces parts, recycled materials even raw materials obtained by extraction,  into newly functional products.  Stainless steel is an alloy made by melting the raw materials that were extracted such as iron ore, chromium, silicon   a...

Assigned roles Questions and Tasks 1. Plot tube length X versus pump flow rate. (X is the distance from the surface of the water to the tip of the air outlet tube). Draw at least one conclusion from the graph. 2. Plot tube length Y versus pump flow rate. (Y is the distance from the surface of the water to the tip of the U-shape tube that is submerged in water). Draw at least one conclusion from the graph. 3. Summarise the learning, observations and reflection in about 150 to 200 words. The team have observed that placement of the rubber tubing and u-tube played an important role in the water flow rate. At first we could not even get the water out of the u-tube as the flow rate was too low to exit the u-tube. After thinking, we increased the water level in my pail as we thought that b was way too high for a low water level. At first, we thought that the pump was too weak, however at the end of the experiment, the water level in the pail should also be taken no...

Reflection We chose the most feasible and suitable material with COWS Matrix. COWS is an acronym for criteria, options, weightage and score. We selected criterias based on the application of the material. Such examples are tensile strength, if the material is carcinogenic, flexibility, etc. The weightages shall then be given to the criteria based on its importance depending on the application of the material, this also plays a huge role in giving scores to find out which material is the most suitable. Scores will be usually given from 1-3 with 1 being the worst and 3 being the best. The most suitable material will be identified by having the highest score. Group Assignment Our group have been tasked to select materials for a single use (disposable) water bottle that does minimal environmental harm. Step 1: List the material requirements for the design The first requirement is corrosion resistant. This prevents the material from corroding and contaminating the water when it...
