Program Outcomes of 3 & 5
Student's Evidence (PO 3)
PO3 - Conceive, Design, Implement and Operate solutions for complex engineering challenges that meet specified requirements with appropriate consideration for public health and safety, cultural, societal, environmental and economical considerations
​
PO3 Attainment: 85
Self Assessment: 4/5
This PO relates to how an individual solve for complex engineering challenges by conceiving and implementing solutions which meets considerations on economical, environmental, cultural, societal and public health and safety factors.The module that maps this Program Outcome is Mechanical Engineering Group Project (MEGP). This module is separated into two courses (MEGP 1 & MEGP 2) with a span across two semesters. Furthermore, this module required student to apply the Conceive, Design, Implement and Operate (CDIO) framework toward projects to solve the complex engineering challenges. Throughout the module, my team was engaged with Daikin Malaysia Sdn. Bhd. to design a Phase Change Material Heat Exchanger (PCM-HE) with existing heat pump unit. The objective of this project is to improve the heating efficiency while reducing the defrost time of outdoor unit with the PCM-HE prototype. My team started the project with Conceive and Design in MEGP 1. Research was done and the team did a thorough brainstorm on how to design the PCM-HE prototype. Besides, formula was given by Daikin Malaysia Sdn. Bhd. for some important calculation. The team came out a few designs and the finalised design was chosen with Decision Matrix approach. PCM-HE consists of two sub-systems, namely Thermal storage system and electrical system. Throughout MEGP 1, this project was awarded to be the Best MEGP 1 Project after the project was assessed by both Academic and Industrial Supervisor.
In MEGP 2, my team continue the MEGP 1 with Implement and Operate. My team started with fabricating a thermal storage tank to store the PCM. The sizing of the thermal storage tank was designed from the calculated data with specified formula during MEGP 1. Besides, electrical system was designed to control the heating and defrost mode automatically. After completed the entire prototype, the prototype was tested in Daikin Malaysia Sdn. Bhd. test room. The prototype with the entire integrated system was tested with standard conditions and it could proceed with specified extreme conditions to tackle the project objective. Overall, my team was able to solve engineering challenges with consideration with public health and safety, cultural, societal, environmental and economical. The team also displayed the code of ethics as an engineer to follow the guideline as a profession.
Student's Evidence (PO 5)
PO5 - Create, select and apply appropriate techniques, resources, and modern engineering and IT tools, including prediction and modelling, to complex engineering activities, with an awareness of the accompanying assumptions and limitations
​
Attainment: 80
Self Assessment: 4/5
This PO relates to how an individual utilise the right technique, tools and resources on predictive and prescriptive modelling, taking into account assumptions and limitations to solve complex engineering activities. There are two modules map with this PO, namely Numerical Analysis for Engineers with Application and Computing Application for Engineer. In Numerical Analysis for Engineers with Application module, I had completed an assignment to apply the Finite Element Analysis (FEA) approach to analyse an existing air-conditioner outdoor unit bracket with ANSYS software. In the assignment, I was opted to determine maximum equivalent stress of the bracket to validate if the bracket meets the safety factor requirement. If it meets the safety factor requirement, I needed to determine if there are rooms for optimizing the design of the bracket. In addition, I conducted Grid Independent Test (GIT) to determine the most efficient and accurate meshing during the meshing stage. Lastly, I determined the existing bracket met the safety factor requirement and I had optimized the design which still able to meet the safety factor requirement by reducing the thickness for the purpose of cost reduction.
In Computing Application for Engineer module, I had done an assignment that was required to develop a set of programming code by the usage of MATLAB. The assignment’s objective was to develop a set of programming code to avoid congestion in a city. The city allowed vehicles with odd and even car plate numbers to enter on alternate days. And the vehicles car plate numbers that entered the city would be displayed in a list at the end of the day. Eventually, I was able to tackle the assignment’s objectives by developing the set of programming code. The programming code is attached below.
