This research paper presents a knowledge-based system for creative design tools (CDT). The main aim of
the developed CDT system is to provide designers with a flexible creative design environment to enhance
their creative design thinking. Several creative thinking tools are developed and integrated with constructive
knowledge databases to widen the search space and expand the design domain. CDT incorporates: a user
interface, creativity tools, knowledge databases and five design modules namely: preparation, concept
generation, design development, evaluation, and detailed design. A case study is discussed and
demonstrated to validate the developed system.
