Giving an idea a visual form is the aim of conceptual design. To that aim, the three key components of conceptual design’s objectives are as follows:

1: To establish a basis of logic:

Emotion and intuition often rule the various artistic disciplines. However, designs are intended for use. A design, whether it be a piece of software or a logo, must, in addition to being aesthetically good, achieve something functional, like communicating information or expressing a brand.
It is conceptual design that grounds the artwork in the why and how of everyday life.
2: To create a design language:

Designers must bridge the gap between abstract ideas and visual qualities because the notion is ultimately simply an idea. Design language refers to the deliberate use of design components to convey and evoke meaning.
As previously said, the conceptual design stage won’t go so far as to plan every aspect of style, but it will create the foundation for important design decisions later on.
3: To achieve originality:

Nothing is original, according to a proverb, and to some extent, this is true. Like every artistic profession, design has a long history, with designers advancing on the ideas of the past.

But you ought to at least aim to stand on those giants’ shoulders. In the design process, the concept and ideation stage is where truly original creative sparks are most likely to occur.
