Recently, the creative industry has been growing faster world-widely and the segment of creative product design plays a key role. This research aims at investigating the design thinking of cultural creative products on visual arts segment. The methods of documentary analysis and K.J. methods are adopted to analyze the key elements of design model and to deduce the background theories. The finding of the research is the design thinking involves the interaction of the three categories: sensibility, understanding and speculative. Specifically, the background theories of sensibility level include Aesthetics, Semiology and Hermeneutics. The background theories of understanding level include Epicureanism, Deconstruction and Post Modernism. The background theories of speculative level include Psychology, Sociology and Management. As level of thinking is validated interactively, therefore a multi-dimension of thinking along with related theories are crucial ground rules in design. A design, based on related theories, could fully illustrate a creative product and make cultural creative industry continuously develop its creativity.
