For the development of high-functional and complex mechatronics products, it is becoming necessary to manage the design process considering multi-domains such as electrical, mechanical and software specialties. However, at present, in the process of embedded software development, the software developers often have to spend their time and efforts by wasteful and unnecessary design iterations because that they don't understand the original requirements and previous designing intentions exactly. The authors predict that the mechanical designers in previous processes, don't describe the reasons, how to analyze and why to adoption technologies insufficiently. In this paper, the authors propose that the requirement model should be introduced in development process, because all designers can understand "what to make" precisely. In reference of the studies of various requirement definitions, especially object-oriented approach, the authors studied that the procedure of description in the requirement model, which is suitable for the development of high-functional and complex mechatronics products. An intelligent crane system is designed as an example to examine the possibilities of description using SysML. In conclusion, proposed requirement model is confirmed that it can surely describe the product requirement of the mechatronics product.
