Week 14

Sup guys Zaiyan here with the week 14 blog SHEEESHHHH. For this week’s lesson, we will be doing product sketching which is honestly fun and interesting compared to what we have been learning. Kind of nice to take a break from the overload of calculations. Nevertheless, let's begin!

PART 1

So why is drawing/sketching important? It is a key technique for creative expression in product design. Sketches or drawings enhance our understanding and provide visual clues for possible further refinements and revisions of the product. After learning about the concept of drawing/sketching, we carried on with our warmup.

Firstly, for our warmup, we sketched straight lines, connecting from 1 point to another and we repeated it a few times. After drawing the straight lines, we then drew curves connecting 3 points in a single stroke. Lastly, we sketched circles within 2 parallel horizontal lines and ellipses within 3 vertical lines. These can be seen from the pictures above.

One perspective drawing

So what is one perspective drawing? Basically, the drawing has one vanishing point which lies on the horizon line. All lines parallel with the viewer’s line of sight then recedes to the horizon towards the vanishing point. Thus, our exercise was to draw a milk carton. Honestly, not the best but still can be improved along the way as you can see in the picture above but it was interesting trying to sketch and draw a product from a one perspective.

Two-point perspective

2-point Perspective Drawing is defined by 2 vanishing points that represent 2 converging points an infinite distance away. Thus, to practice this 2 point perspective drawing, we were tasked to draw a book using the 2 point perspective. Some examples of our drawings can be seen in the photos above.

PART 2

For part 2 of the lesson, we learnt about design specifications. A 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.

1.Design specifications provide product design teams with the information they need to build out new features or functionality of a product.

2.Good design specifications allow product designers to answer the following questions:

• What are we building?

• What should the final build achieve?

• How do we measure success?

Type of Specifications relevant to Product Design

Test Standard-e.g. ASTM E18-20 Standard Test Methods for Rockwell Hardness of Metallic Materials

For Activity 2, we created a design specifications table for our group’s chemical product, by referencing the design specifications table our lecturer provided.
