Language of sketching
Techniques, vocabulary

Ideation is the creative process of generating, developing, and communicating new ideas, where an idea is understood as a basic element of thought that can be either visual, concrete, or abstract. Ideation comprises all stages of a thought cycle, from innovation, to development, to actualization. Ideation can be conducted by individuals, organizations, or crowds. As such, it is an essential part of the design process, both in education and practice.

Visual ideation
Ideation is the process of generating ideas. Once you have your idea, you can jump into visualization, which is the process of transforming a concept or idea into a visual. This process should be about pointing out your goal, and then trying to figure out various visual solutions to that intended goal.

A sketch (ultimately from Greek σχέδιος – schedios, "done extempore") is a rapidly executed freehand drawing that is not usually intended as a finished work. A sketch may serve a number of purposes: it might record something that the artist sees, it might record or develop an idea for later use or it might be used as a quick way of graphically demonstrating an image,
idea or principle.
Sketching is also used as a form of communication in areas of product design such as industrial design. It can be used to communicate design intent and is most widely used in ideation. It can be used to map out floor plans of homes.

Also more general:

Doodle, Scribble
A doodle is a drawing made while a person's attention is otherwise occupied. Doodles are simple drawings that can have concrete representational meaning or may just be composed of random and abstract lines, generally without ever lifting the drawing device from the paper, in which case it is usually called a "scribble".

Cut-up technique
The cut-up technique (or découpé in French) is an aleatory literary technique in which a written text is cut up and rearranged to create a new text. The concept can be traced to at least the Dadaists of the 1920s, but was popularized in the late 1950s and early 1960s by writer William S. Burroughs, and has since been used in a wide variety of contexts.

Innovation in its modern meaning is "a new idea, creative thoughts, new imaginations in form of device or method". Innovation is often also viewed as the application of better solutions that meet new requirements, unarticulated needs, or existing market needs.

Form finding, shape finding
Design process of developing new form languages, new relation between forms. Frequent in architecture and automotive design.
More to read:

Form language
A form language, consists of geometrical rules for putting matter together. It is visual and tectonic, traditionally arising from available materials and their human uses rather than from images. Different form languages correspond to different architectural traditions, or styles.

Design language
A design language also known as design language system, design vocabulary is an overarching scheme or style that guides the design of a complement of products or architectural settings.
