系統化設計方法步驟包含對設計問題及目標的瞭解，並考慮產品的規格及設計限制，在構想設計階段中尋找出符合功能要求之可能解，設計者再從其中挑選出最具可行性者進行細部設計及改良。
在整個設計階段中，最重要的是構想設計。然而，CAD真正在概念設計階段輔助設計者從抽象的概念推導出具體之結構及模型並不多。因此在本研究中，以螺絲起子為例建立其功能模型，找出符合每個次功能之所有可能解，應用型態圖之方法，透過VB建立之介面，以Microsoft提供之COM功能，呼叫CATIA物件並在CATIA下建立可能的實體模型並自動進行組裝。由於實體模型之建立是以特徵為基礎，因此其參數幾何資料可藉由Excel表單將其儲存，對於未來的設計變更或再設計，本系統可以提供設計者在外形概念實體化階段相當好的協助。

The procedure of systematic design of a product includes understanding design task, generating primitive design concepts, and transforming primitive layouts to satisfy design objectives and requirements. After evaluation, the most promising design layout will be chosen for analysis, test and modification during embodiment and detail design. Among the design processes, conceptual design derived from product requirements is the most important step. However, current CAD-systems don’t support the crucial design decision in this stage.
This research proposed a computer-aided shape conceptualization design system, which is based on the method of morphological chart and together with functional analysis. Then, methods with a discursive bias are employed to help designers generate concepts and search for solution principles. The solution principle for each sub-function can be selected from the possible solutions stored in morphological chart. The selected solutions are then combined to create a variety of primitive design. The definitive design layout can be determined by employing the evaluation criteria proposed by Cross.
Additionally, the prototype system developed in this research used the programming techniques of VB to create a human-machine interface that is to access the CATIA objects under COM (Component Object Model) environment. The solution principles defined as feature-based solid model can be reached or stored in Excel tables through the prototype interface.
The case study of screwdrivers has demonstrated the shape conceptualization design processes proposed in this study that is capable of generating various design layouts to meet the product requirements.
