“Unconscious design” evokes people's familiarity with new things, which contributes to achieve effective communication truly between users and design. This article focuses on the application of behavioral stimulation in design, and aims to explore ways to integrate user unconscious behavior into design to reduce users’ burden, which brings the fun and a sense of accomplishment to users, and provides guidance for the design and application of household baking appliances.The concept of “unconscious” and the concept of “unconscious design” are summarized. This paper analyzes the design application mode of behavioral stimulation, summarizes the principle model diagram for elaboration and explanation, and enumerates classic design cases for proof. Finally, the feasibility of the principle model diagram is demonstrated through the design practice of household baking appliances. The application of behavioral excitation mode principle model to the design practice of household baking utensils can effectively guide users to operate correctly. Behavioral stimulation of “unconscious design” establishes a benign interaction and coordination relationship between users and products. In the context of personalization and emotional design, with baking utensils as the carrier, it reflects more emotional care in the details.
