Week 7

For this week’s lesson, we learnt about product development using Computer-aided Drafting and Drawing (CADD).

Introduction to Computer-aided Drafting and Drawing (CADD)
Computer-aided Drafting and Drawing is the use of software to sketch and design physical components. We will refer to Computer-aided Drafting and Drawing as CADD in this blog for convenience. With the help of CADD, shapes and lines can be crafted easily and the content can be easily copied, shared, edited and saved. CADD also allows accurate calculation of dimensions. Advanced CADD software is also able to estimate the classification and quantity of material used or the length of manufacturing time required, which facilitates budget planning. Hence, it will be useful to learn how to use and apply CADD as it will help us in product design in the long term.

Pre-Lesson Activity
Before W7’s lesson, we had to download Autodesk Fusion 360, which is the CADD software that we would be using. We had to acquire some basic skills on how to use the software in order to prepare us for the actual lesson. Each of us created a keyring with our own initials on it. Since it was the first time using this software for the team, we spent quite a bit of time figuring out how to use the software. After a few tries, we got the hang of how to use the software and we finally managed to design our own individual keyring.

Lesson
During the lesson, we learnt more about the use of constraints by following our lecturer's instructions to improve our experience when using Fusion 360. This activity was easier for us to complete as we had already acquired some basic skills on how to use the software, and we were able to navigate through the software more easily. We learnt how to mirror objects along a line and also how to use the tangent functions.

Final Activity
For the final activity, we were tasked to make a photo frame consisting of the photo frame, U-shaped photo holder, back panel and transparent sheet.

We were each tasked to do one part of the photo frame and this is how we decided to split the work up:
  • Xavier- Transparent Sheet
  • Nick - Photo Frame
  • Kieran - U-Shaped Photo Holder
  • Anwar - Back Panel
It took us a while to complete this activity as we did not have a reference guide to follow and we had to learn what we applied earlier on. We had to make sure that everything was up to specification and fit within the given dimensions. One part of the frame could not be bigger than the other to ensure that the final photo frame did not look weird and ill-proportioned when assembled.

Week 1 Team Introduction and Team Bonding

Image
ICPD is also known as Introduction to Chemical Product Design. It is a module that will develop learners with an aptitude for chemical product design. It will require our team to conceive and design a chemical product. The team consists of Kieran, Anwar, Nick and Xavier. Our team name is Team KANX (pronounced "cans"). Team Introduction Team member 1: My name is Nick, and I like reading comics, music and video games. Team member 2: My name is Kieran, and I like playing sports and watching TikToks during my free time. Team member 3: My name is Xavier, and I like trying new things. Team member 4: My name is Anwar, and I like watching and playing football. Team Rules Contribute actively online and offline Complete and submit all our work on time This blog is for us to track and update our progress weekly to ensure that we are making sufficient progress for each week. Since we are a new team, we decided to do some activities together as a group to form a team bond between members....

Week 1 Activity

Choosing household-appliances, the chemical product we have selected is the refrigerator. The refrigerator is an essential household appliance, as it helps to preserve our food at low temperatures and keep food fresh. The temperature inside the refrigerator must be maintained at a low temperature to slow down the bacterial growth in our food. A refrigerator does this by transferring heat from its interior to the exterior. The components of a refrigerator consist of an evaporator, compressor, condenser, throttle valve, capillary tube and thermostat. A refrigerator works based on the vapour-compression cycle, also known as the refrigeration cycle. Inside the refrigerator, the liquid refrigerant enters the evaporator, evaporating completely at a constant pressure. Heat is absorbed from the surrounding region to be refrigerated. At the same time, the capillary tube reduced the pressure on the refrigerant, allowing it to evaporate at a lower temperature. The gaseous refrigerant leaves the e...

Practical 2

Image
For Practical 2, we have been tasked to complete the air pump challenge at home due to COVID-19. Background information An air lift pump is used to lift water from one location to another using compressed air. Liquid enters from one end of the pump (inlet), while a mixture of air and water discharges from the other end (outlet). The compressed air is mixed with water. Since the density of air is lower than that of water, the air will quickly rise to the top. As the water mixes with air, the density of water decreases, as the density of the air and water mixture is lower than the density of pure water. Thus, as the vapour bubbles rise, they carry along some liquid upward due to fluid pressure. Materials and Experimental Setup Figure 1. Materials used 1. Water container 2. U-tube 3. Measuring jug 4.
