I am Nick from Team KANX, and this blog will serve as a way for me to document my learning progress in the new module, Chemical Product Design and Development. It will be updated progressively as my groupmates and I learn more about the various skills that will be taught in this module. More About Myself I like listening to music. My favourite artiste is Rick Astley. I read adult fiction and horror in my free time. Introduction to the New Module Chemical Product Design and Development, or CPDD, is a continuation of Introduction to Chemical Product Design from Year 2 Semester 1. It will enable me to gain various skills and techniques in chemical product development and experimental designs. My Personal Goals From this module, I hope that I will be able to improve my own critical and interpersonal communication skills. In the previous semester, our group ran into some issues regarding report submissions near the end of the previous semester due to a few miscommunications on my part. To i

Project Development

1. Our Team Chemical Device For our project, we worked on creating a functional tea maker. Its main objective is to combining the heating and infusing process of brewing tea into a single machine, therefore making the tea preparation process more convenient and simpler. In order for it to work, it requires a certain volume of water and a measured amount of tea leaves in order for it to work. The hot water poured on the tea leaves in a tea basket/infuser attachment allows the tea leaves to steep. Different tea types have different brewing requirements, as each tea type has their own optimum brewing time and brewing temperature to extract the best flavour. By conducting some secondary research online, we found that there were some issues plaguing the current models of tea makers in the market. Firstly, tea makers can be quite expensive, especially those with a lot of different functions. Next, modern tea makers tend to be made up of more intricate parts, making them more complex and more

Hypothesis Testing

Week 14 (Tutorial) For the tutorial session in week 14, we were introduced to hypothesis testing. Background Information Hypothesis testing refers to the formal procedures used by experimenters or researchers to accept or reject statistical hypotheses. Step 1: State the statistical hypotheses. This involves stating the null hypothesis (H 0 ) and the alternative hypothesis (H 1 ). The null hypothesis states that differences in sample observations result purely from chance and that there is no statistically-significant difference in a set of given observations. The alternative hypothesis states that differences in sample observations are statistically-significant and influenced by some non-random causes. Step 2: Formulate an analysis plan. There are two commonly used statistical tools, which is the t-test and the z-test. The t-test is usually used when the sample size is lesser than 30, and the z-test is used when the sample size is greater than or equal to 30. At this juncture, we will

Design of Experiment (DOE)

Week 12 and 13 (Tutorial) For the tutorials sessions in weeks 12 and 13, we were introduced to a concept called Design of Experiment, or DOE for short. Background Information DOE is a statistics-based approach to designing experiments. It acts as the backbone of any product design, as well as any process or product improvement effor. It allows us to obtain knowledge of a complex, multivariable process with the fewest trials possible through optimisation of the experimental process itself. This is achieved by first determining a set of factors which are most important to the system or process, and concluding through trial and error at what levels these factors must be kept to optimise the process or system performance. Its main benefit is that it provides a quick and cost-effective method to understand and optimize any manufacturing processes. For the activity for this learning topic, we completed a case study which was designed to help us apply what we had learned about DOE. We were gi

3D Printing

Week 7 (Tutorial) For our first tutorial lesson in week 7, we learned more in-depth about 3D printing. We had previously gone through the basics of 3D printing in the previous semester. Background Information 3D printing is a form of Additive Manufacturing (AM), where a physical object or part is created from a 3D digital model file by adding and laying down successive thin layers of material upon one another. 3D printing allows us to create objects that cannot be normally created using subtractive manufacturing. Workflow in 3D Printing 1. Creating a printable 3D Design in Fusion 360 Firstly, we have to create a 3D digital model file in a 3D modelling software. For example, Fusion 360 is a Computer-aided Drafting and Drawing (CADD) software that allows us to sketch and design physical components. 2. Converting the 3D design into a 3D representable file (STL or 3MF) These are the common input file types for 3D printers. This step can be done by exporting the 3D digital model file as an
