This PO relates to how an individual able to solve the engineering challenges that takes into consideration of public health and safety, cultural, societal, environmental and economical using the CDIO approach which are Conceive, Design, Implement and Operate. 

​

The two modules that can be mapped into achieving this program outcome are the Mechanical Engineering Group Project 1 (MEGP 1) and Mechanical Engineering Group Project 2 (MEGP 2). For MEGP 1, my group had built a small scale prototype of solar panel cleaning robot. In the Conceive stage, we had conducted research on the current cleaning methods in the existing market. Besides, we also conducted an interview to obtain all the related information such as cleaning procedures and types of solar panels used in the solar farm. This stage is crucial as it helps us in the design process later on through broadening our knowledge regarding the types of technology currently available. In the Design stage, we brainstormed design ideas and proposed our finalized design. The finalized design includes the dimensions of every parts, price, sources and the type of material used for each parts. The rough sketched of our proposed design was then recreated using SolidWorks into a detailed design with refines, specifications and estimates. Then a final prototype was built with sustainable and environmental friendly material using the 3D printer. 

​

For MEGP 2, my group had fabricated an actual scale of the solar panel cleaning robot. During the Implement stage, we first purchased all the electrical components and materials required and started with the assembly of all the sub-systems into a full integrated system. Before purchasing, we had emphasized on acquiring recycled/used materials and components as it not only helps to save cost but also helps to contribute in sustainability.  After full assembly and touch up, testing and adjustment of the integrated system was done to improve on its accuracy and efficiency. In the Operate stage, we had created an instructional technical operations & maintenance manual to help the user on how to use the product with ease as well as guidelines on how to properly use and maintain the product after usage. The manual is also important as it helps to avoid any serious injuries due to misuse/mishandling of the product. Last but not least, my group had received the Taylor's Capstone Award for winning the best design.

This PO relates to how an individual able to apply appropriate techniques, resources, modern engineering and IT tools such as prediction and modelling into engineering activities with the present of assumptions and limitations. 

​

The first module that can be mapped into achieving this program outcome is Computing Applications for Engineers (MATLAB). For this assignment, I utilized my MATLAB knowledge and skills into developing a code that meets the outcome of the objective. The objective of this assignment is to come out with a code that allows odd or even number plates to pass through a checkpoint on different days. Besides, the code must also designed in a way that the allowed number plates through the checkpoint to be display on the command window. Although there might be some limitations or uncertainties for the MATLAB code to be applied in real life situation, I still find that this software is somewhat practical as it has the tendency to verify the code function.

​

The second module that can be mapped into this program outcome is Numerical Analysis for Engineers with Applications using ANSYS. For this assignment, I am required to analyze the stress component of a dumbbell rack using ANSYS simulation. In order to perform stress analysis on the object, I had sketched out the a model of the dumbbell rack according to the real life dimension using SolidWorks software. Then, the file was transferred into ANSYS to perform the stress analysis. A design optimization of the dumbbell rack was done by modifying certain parts of the design to obtain a better average skewness and to improve on the safety factor. The modification includes changing the angle for the arm support, reducing the length of trays and reducing the amount of materials used which leads to cost reduction. A final practical design was obtained after the analysis was made with justifications. Although there will be some of the limitations when it comes to simulation, I still find that these software serves as a very reliable and efficient tool before begin with the manufacturing process of a real design model.
