Week 14

 Welcome to our Weekly Blog! This week, our class learned about sketches and specifications. But before we get into that, we must understand why it is important.  

 

Sketching and specification is important because it is a key technique in for creative expression in product design, enhance understanding and provide visual clues for possible further refinements and revisions of a product. 

After understanding the concept behind sketching and specification, we were given 4 simple task to practice our sketching skills namely sketching straight lines, sketching curve lines, sketching circles, and sketching ellipses as seen below! 

 

 

Afterward, we were taught the basic skill of One point perspective. To elaborate further, one point perspective means that the drawing has a single vanishing point, usually opposite the viewer’s eye and usually on a horizontal line. Additionally, all the lines are parallel with the viewers line of sight recedes to the horizon toward the vanishing point. 

To enhance our understanding of one point perspective, we were given a simple task of drawing a milk carton using the concept and as you can tell, we were not the best artists :p 

After that activity, we were introduced to another concept called Two-point perspective. In layman's terms, it can be defined by 2 vanishing points that represent 2 convergence point and infinite distance away. 

 

To enhance our understanding of two-point perspectives, we were given the activity of drawing a book using that concept as seen below! 

 

Lastly, we were taught about design specification. To understand design specification, we must define its meaning. Design specification refers to a set of documented requirements to be satisfied by a material, design, product or service. This provides product design teams with the information they need to build out new features or functionality of a product. 

 

In specification related to design, there are different types of specification used, mainly Material specification, Functional specification, Standard specification and Test standard. 

For our final activity, we were asked to make design specification table based on our cold brew coffee machine.

And with that, this is all for our weekly blog. Thank you for reading!!!
