Introduction For this week’s ICPD lesson, we have learnt about design specifications as well as sketching using free hand. This lesson is separated into two parts, part one being “Product Sketches” and part two being “Design Specifications”. Part One: Product Sketches Sketching is important in prototyping as it is beneficial because it aids in the validation of assumptions, the early detection of problems, the brainstorming of ideas and the conduct of early usability testing. Before anything, we were each given 5 sheets of paper and were instructed to practice on our free hand drawings by drawing different shapes and lines. We then proceeded to draw objects using 2 and 3 point perspective.

Introduction For the lesson in week 13, we learned about operating principles and mechanism designs. Operating designs are essentially all about How Things Work. Mechanical, electrical, chemical, and magnetic functioning principles are used to design all devices, apparatus, and equipment. There are many examples of operating designs. For starters, the most basic and everyday need is coffee. How is a cup of coffee made? Hot water is introduced to the coffee beans and then it leaches the soluble solute from the coffee beans, making coffee solution or coffee. Our Chemical Product Operating Principle Our chemical product principle is based on the transfer of heat through conduction and convection. The water at the bottom gets heated up by the heating source at the bottom of the heater by conduction. As the water at the bottom heats up, it expands and thus becomes less dense. As the water at the bottom becomes less dense, it rises as the cooler water at the top sinks because it is de...

Practical 4 Introduction: For this practical session, we conducted the practical once again in the FabLab in Singapore Polytechnic. During that practical, we were given 2 hours to construct a game or toy using cardboard. We were able to make a fully functional and working toy using the different cardboard joineries that we learnt from the previous practical (Practical 3). We were then given 5 minutes to present our toy. We were also given 2 ice cream sticks each which represented our vote, to vote for the best toy that we like. The toy that we created was a fully functional and easy to play “Air Hockey” (Figure 1), that is made out of cardboard. Figure 1: Air Hockey Thought Process The team wanted to create a fairly easy and fun filled game for the Primary 4 students. Hence, why not the class “Air Hockey” that everybody loves to play at the arcade? We decided to bring this idea and construct it for this practical assignment. The components that we have created to form this f...
