Aiming at the technology limitation existing in traditional patent acquisitions, six types of innovative attributes were used to construct a multi-attribute representation model for patent knowledge:contradiction, substance-field, function, inventive principle, inventive standard and effect. In addition, each innovative attribute could be described by the corresponding attribute-hierarchy tree, thus the specific organization strategy as well as the algorithm process were presented to organize patents from different levels of abstraction. Furthermore, an application framework based on the above model was put forward. As a result, a local patent database was constructed based on multi-attribute and multi-level, which could support the comprehensive expression from different attribute views and the effective obtaining in different levels for patent knowledge. In conclusion, it was conducive to break the limitation of technological field and promote the efficient obtaining of cross-disciplinary and cross-field patent knowledge, which could help designers get inspiration in the process of analogical transferring. Finally, the case of nanometer-sized hollow nickel spheres was used to demonstrate the practicability of the model.
