What is design?
Design is planning a product before making it, so that it works well, is safe and pleasant to use. A designer thinks about the user, the material, the cost and the look. Technology makes the product. Design decides what to make and how it should be.
Industrial aesthetics
Aesthetics means how pleasing something looks and feels. Industrial aesthetics is beauty in things made in factories in large numbers: bottles, chairs, phones, cars. Good industrial design joins:
- Function: it does its job well.
- Ergonomics: it fits the human body, like a handle that your fingers hold.
- Form: shape, colour and surface that look good.
- Cost and material: it can be made cheaply and safely.
A saying goes: "form follows function". First decide what the product must do, then give it a shape that suits that job.
Folk crafts
Folk crafts are objects made by hand with traditional skills passed from teacher to student. Each region has its own materials and patterns. In Russia you find painted wooden ware with red, gold and black patterns (khokhloma), blue-and-white painted porcelain (gzhel) and nesting dolls. In India, examples are block printing on cloth, Madhubani painting and brass work. Folk crafts keep culture alive, give work to artisans and give ideas to modern designers, who often borrow their patterns.
Digital production
Digital production means making objects from a computer file.
- CAD (computer-aided design): you draw the object on a computer.
- CNC machines: they cut or carve a material by following the file.
- 3D printing: a machine builds the object layer by layer by adding material, often plastic.
The same file can be used again and again, changed in seconds and sent to another city. It is good for prototypes (first test models) and small batches.
High-tech industries
High-tech industries use new science and a lot of research. Examples: microchips and electronics, robots and automation, medical devices, aircraft and space, and renewable energy. They need skilled people, clean workplaces and strong design, because small parts must fit exactly. Even here the first step is design.
Key formulas and definitions
- Good product = function + ergonomics + form + safe cost
- Form follows function
- Digital production: CAD file, then CNC or 3D printer, then the object
- 3D printing = adding material layer by layer
Worked examples
1. Why does a good mug have a handle and a gentle curve?
The handle keeps your fingers away from the hot drink (function and safety) and fits the hand (ergonomics). The curve makes it pleasant to look at (form).
2. A craftsperson paints each wooden spoon by hand. A factory prints the same pattern on 1,000 spoons. Which is folk craft?
The hand-painted spoon with traditional patterns is the folk craft. The factory print copies a pattern by machine, so it is not the craft itself.
3. A 3D printer uses 24 layers of 0.5 mm each to print a cup. How tall is the cup?
24 × 0.5 mm = 12 mm tall.
Common mistakes
- Thinking design is only about looks. It is about use, comfort, safety and looks together.
- Calling every machine-made pattern a folk craft. Folk crafts are hand-made with traditional skills.
- Thinking a 3D printer cuts a block. It adds material layer by layer.
- Thinking high-tech work needs no design. Design comes first in every product.
