In practice, the use of ProKon, as part of the MTM Design Concept, directly or indirectly affects: – Standardizing processes (quality improvement) by establishing a uniform platform and creating – Designing ergonomically favorable solutions – Giving new impetus to the target-oriented optimization of the product design Identifying and assessing weak points in the design that cause assembly interferences This information includes drawings, multi-level bills of material, prototypes, models or previously manufactured products. Therefore, the application of ProKon is based on information available at the corresponding point of time during the product development phase. These activities can only be optimized after the actual design phase, i.e., during the planning phase (through the application of MTM building block systems). Normally, the designer does not know which non value-adding activities are involved and therefore, cannot take them into consideration during the design phase. The ProKon analysis DOES NOT describe the actual assembly process, which considers such issues as: In general, assembly activities can be classified into the following categories: – ProKon enhances the designer’s creativity, thus supporting the creative processĪpplications and Limitations of the ProKon Method – Avoidance of subsequent product changes – Promotion of cross-functional communication – Creation of valuable basic information for further process planning – Target-oriented reduction of the identified assembly interferences – Quantification of the identified assembly interferences – Identification of assembly interferences at the earliest possible point of time In the assembly of a product, the total of all ProKon Units per analyzing criterion establishes a relative measure regarding the ease of assembly of the product design. For each of these analyzing criteria, a numerical value – a ProKon Unit (PU) – was defined. The influencing factors affecting the assembly are defined as analyzing criteria, represented by basic values or assembly interferences. ProKon describes the assembly process of components and sub-assemblies during the design phase. ProKon supports the systematic identification of possible improvements in design solutions and the quantification of the effect these solutions have on productivity. ProKon is an MTM-based method for analyzing and evaluating design solutions with respect to their suitability for assembly. ProKon – Definition, Advantages and Limitations This perfectly: “I cannot say whether things will get better if we change what I can say is they must change if they are to get better.”īy designing the product for ease of assembly, it is possible to reduce the manufacturing costs (production and material costs) by approximately 20 % to 40 %. The physician and writer Georg Christoph Lichtenberg (1742–1799) described To reduce these costs, the approach must be to avoid costs by taking appropriate measures to minimize these costs during the development and design phases. This correlation is illustrated by the following graph:Īn investigation by the Ford Motor Company showed that the expenses for product design amount to about 5 % of the total product costs, while the final product design determines 70 % of the manufacturing costs.Ī large part of manufacturing costs is caused by production activities (parts processing and assembly). Subsequent changes to products, production techniques and methods are normally difficult to achieve and very cost-intensive.
