Naoto Fukasawa，a famous industrial designer in Japan， proposed the “Without Thought” design theory for the first time， by which he means using conscious design to realize an unconscious behavior and give people a meaningful enjoyment. He pays much attention to the details and emotion in design， and tries his best to blend in more humanistic care in design to make the products no longer merely cold functional objects. His “Without Thought” design theory also reflects the feature of “Form Created in Environment， Conciseness and Exquisiteness”， which attaches great importance to the environment and details， and the form is determined by the environment. All these bring the consumers an enjoyment when using a new product.
