Week 14
Sketches & Specifications
A warm welcome to our fellow readers. Today we'll be looking at the activities carried out in this week's ICPD lesson. Personally, I had a lot of fun doing this activity, and I don't usually engage myself in drawing activities that much given that I'm quite a terrible drawer myself.
Why sketching? Now sketching might sound rudimentary but in the world of product designing, its purpose is of paramount importance as it allows a person to represent their ideas visually and at the same time it opens the doors for better communication between designers and their clients.
Activity 1
As the starter of the lesson, we were assigned with some warm-up drawings to sort of introduce us to the proper ways of drawing sketches. It might sound lame but trust me sketching is not something that you could master overnight. First off we drew a simple horizontal line from two points that were 15 cm apart. Following the first warm-up, we drew three points that were 10 cm apart each and drew a horizontal line that conjoins all three points. Now the purpose of this sketch was to draw the lines in one single stroke without stopping in between. The third warm-up was to draw a circle within two horizontal lines that were 3 cm apart and as part of the last warm-up, we were required to draw ellipses.

We then moved on to the second part of the activity which was to draw a one-point perspective sketch of a milk carton. A one-point perspective sketch is basically a drawing that has one vanishing point, usually directly opposite the viewer's eye and usually on the horizon line. All lines parallel with the viewer's line of sight recede to the horizon towards this vanishing point.

Moving on, we were assigned with a two-point perspective sketch of a book. A two-point perspective sketch is a type of linear in which parallel lines along the width and depth of an object are represented as meeting at two separate points on the horizon that are 90 degrees apart as measured from the common intersection of the lines of projection. Now drawing the two-point perspective sketch is slightly challenging compared to a one-point perspective so Mr. Kok showed a video explaining the steps on drawing a two-point perspective sketch.

Activity 2
Activity 2 focuses more on the design specifications. The design specification is a set of documented requirements to be satisfied by a material, design, product, or service. It is a common preliminary part of any engineering design and product development process. The purpose of a design specification table is to provide the product design teams with the information they need to build out new features or functionality of a product.
Let us have a look at the specifications table that we made for our chemical product ( cooking oil filter)
