The article presents progress in the authors' research work, since the last publication, on the prototype software system supporting the process of designing at conceptual stages. The main focus is on the implementation concepts and the implementation of mechanisms managing the collecting, storage and reuse of design knowledge in the mentioned application. The introduction briefly presents the current stage of work on such issues on the basis of an analysis of publications of other authors dealing with similar issues, with particular emphasis on the most, in the authors opinion, interesting solutions and approaches together with an assessment of their usefulness in application supporting the designing of mechanical devices. The next part of the article is an extensive description of the concept of the proposed process of designing using the functionalities and functionalities’ concepts in the prototype supporting application. The application consists of a relational database, a file system and management algorithms managing the stored knowledge. It is also integrated with the CAD system. Additionally it is possible to integrate it with other systems supporting the design (FEM analyses, simulations, etc.). In this part we base on a real example from the industry. The presented device has been manufactured for several years. During this period, modifications in mechanical structure, electrical system, hydraulic and pneumatic systems were introduced repeatedly. The latest version of the device has been created in accordance with the approach proposed in this paper. At the stage of conceptual design, it helps to identify essential problems, create operating function structures, select the suitable working principles, and also supports the selection and evaluation of solutions. The functionality of the designing process support was achieved through the use of specially designed mechanisms. On the basis of the knowledge stored in the knowledge base, collected during previous experience in designing, but also in producing and operating the previous versions of the device, the mechanisms provide the designer with tips relevant to current needs. The utilization of the accumulated knowledge analysis can be also carried out to support the designer in the detailed design phase. The mechanisms responsible for this process operate in an analogical manner. At this stage, the designer is supported when creating design and manufacturing documentation. In addition, the application allows to store detailed knowledge that mean a documenting individual knowledge development with the description of the premises of taken decisions. The article is completed with a conclusion with the emphasis on the advantages of the proposed approach. The planned direction of developing the design support system is also described.
