One common type of design is visual solution. In this type of design how the letters are arranged is an essential part of communicating the idea. Visual solution is often seen in advertisements as the marketing industry uses this design strategy to appeal to their audience. Chick-fil-a's logo is a great example of visual solution!

Form and content, is an essential design process that explains what will be presented and how it will be presented. Defining the relationship of form and content is a critical part of the thinking stage of the design process. One example of content being clearly communicated by the appropriate image or form is the Jaguar logo.

Icons or pictograms are forms a designer creates to bring simplicity and clarity in communicating an idea. Icons communicate an idea using shapes and pictures instead of words. Although icons provide simplicity, there can be some confusion since sspecific symbols may lose meaning when they cross national, ethnic, or religious borders. The icon for a public restroom is an excellent example of this element of design!
