摘　　要：针对产品设计前期对参数化的需求,提出空间层次规划法,利用产品的结构特点将约束定义与求解过程层次化、模块化;通过申请、查询机制保证约束定义与求解过程的有效性和可靠性;让参数化过程更符合工业设计师的设计习惯;并以板式家具为例验证其可行性。In order to meet the requirements of parametrization in the early stage of design,a space hierarchical planning method is presented.The process of defining and solving geometric constrains is described in a hierarchical and modular way according to the structural features of a product.The requisition-inquiry system ensures the effectiveness and reliability of the process,and makes the process more conformable to industrial designer＇s habit.The feasibility is verified through a example of panel furniture design.

关 键 词：参数化 空间层次规划 约束求解
