Aesthetics in machine design | The Mechanical post

You may have heard about the word "Aesthetics" especially when someone is speaking about the design of a product.

Have you ever wondered about, what is aesthetics? and what is its importance in design? 

Hello there! Welcome back to The Mechanical post and today we'll be looking at what is meant by aesthetics in machine design? 

Aesthetics in machine design | The Mechanical post


Definition of Aesthetics

Aesthetics is characterized as, " A set of standards of valuing a marvel". It deals with the outside appearance of the product.

 Appearance is an outward articulation of the nature of any item which makes the first correspondence of the item with the shopper.

Capacity, cost, security, and physical parts of ergonomics might be significant in the underlying phases of machine design, however, the aesthetics of a product is a very important deciding factor on how well the product would perform in the market.

An ergonomic design along with great aesthetics which is satisfying to the eye gives a visual impression that the product will perform the desired task very well.

Aesthetic consideration in design:

Following are the aesthetic consideration in design:
  • Shape of designed part
  • Symmetrical balance
  • Colour
  • Continuity
  • Variety 
  • Proportion
  • Size
  • Contrast
  • Impression & purpose
  • Style
  • Material and surface finish
  • Tolerance
  • Noise

1. Shape of the designed part :

There are 5 essential states of a designed part, i.e. step, taper, smooth running or streamlined, shear and sculpture. The outer state of any item depends on the mix of these shapes.
  • Step structure: It is a ventured structure having vertical emphasis like multi-storeyed buildings.                                                                                                  
  • Taper structure: It comprises of tapered blocks and cylinders.                                  
  • Shear structure: It has a square standpoint.                                                                
  • Smoothed-out structure: It has a smooth streamlined aerodynamic structure like the outer profile of modern supercars and airplanes. Check out the different types of cars based on their body style.                                             
  • Shear structure: It comprises ellipsoid, paraboloid and hyperboloid shapes.

2. Symmetrical balance :

The vast majority of the structures which exist in nature are around balanced about at least 2 axes. The natural eye is consequently used to see things in balanced structures and patterns to dismiss asymmetrical shapes as terrible. In many man-made items, evenness along at any rate one pivot improves its stylish intrigue.

In any case, in the event that utilitarian prerequisites demand asymmetry, at that point the asymmetry must be balanced out. 

3. Colour : 

 Colour is one of the major contributors to the aesthetic and appeal of a product. The selection of color should be compatible with conventions. 'Morgon' has suggested the following colour codes with meanings:

📕Red =  Danger, hot.
📙Orange = Possible danger.
📒Yellow =  Caution.
📗Green =  Safe.
📘Blue = Cold.
📓Grey = Dull.

4. Continuity :

An item that has a great progression of components is tastefully engaging. eg: At the purpose of changing cross-segment if a filet is given, it shows progression in the item and in this way improves its appearance.

5. Variety: 

Variety is useful while making a wide range of products. For e.g. Appliances such as laptops etc are manufactured in a number of variations by a single manufacturer, despite the fact that all items perform the same function.

And speaking of laptops, check out the best laptops for mechanical engineers.

6. Proportion: 

Proportion is concerned with the relationship between parts of the product. The product which is out of proportion is not aesthetically pleasing. For e.g. the spanner in figure 1. is functional and easy to manufacture but is not aesthetically pleasing and out of proportion. 

However, the spanner in figure 2 is in proportion and aesthetically pleasing.

7. Size : 

The size of the product must be ideal for that particular use. It must not be too large or too small. A properly sized part greatly affects the aesthetics of a product.

Nowadays because of advances in the electronic field originators can utilize beforehand unaccepted lodging for incorporated things for some plan requirements.


8. Contrast : 

Contrast is the distinction between adjacent elements of any product, which have clearly different characteristics and functions. Contrast improves the appearance of the product.


9. Impression and purpose:

The item should give the impression of palatable execution. Tighten shape invigorates the impression of and security. For eg; security vehicles have a commanding and bulky appearance which gives the impression that the vehicle will serve its purpose.


10. Style :

Style is the visual nature of the item. Style makes it more alluring and engaging than different items doing likewise work.


11. Material and surface finish :


Material contributes fundamentally to the appearance of the item. Stainless steel gives a preferable appearance over the cast iron, plain carbon steel, and low combination steel.

Items with better surface completion are additionally satisfying. The surface covering measures like splash painting, electroplating, and so forth upgrades the intrigue of the item.


12. Tolerance : 

Proper tolerance given to mating parts improves the aesthetic appeal of the product along with conveying that the product is of good quality and well built.


13. Noise:

Undesirable commotion is upsetting and marker of some glitch inside the item and henceforth it significantly decreases the stylish intrigue.


Advantages of Aesthetics:

  • A market is a competitive place, and with thousands of alternatives for the same product, it becomes necessary to stand out. A product with better aesthetics is very likely to grab attention and thus increase sales.                                   
  • A product with good aesthetics also increases its popularity, thus benefitting the company directly and indirectly.                                                                               
  • It also helps build a loyal customer base for the company.                                               
  • It gives the consumer a sense of satisfaction.
