The modern market requires innovative approaches to defining equipment requirements, emphasizing competitiveness, quality, reliability, and flexibility in the transition to new products for multiproduct job lot production. The implementation of mechatronic systems often leads to negative outcomes due to technical errors and suboptimal economic performance. This is often caused by limited competence of clients and suppliers, low technical standards, and violations of design principles. The technical and operational characteristics of mechatronic modules for electrical discharge alloying include localized coating on figurine-shaped detections within the framework of multiproduct job lot production, with varying physic-chemical properties of the alloyed layer. When designing mechatronic modules, it is important to consider factors such as production conditions, batch size, productivity, operational integration, product interchangeability, software characteristics, component reliability, and information connectivity. The engineering process of mechatronic modules (MM) begins with the development of a conceptual framework that includes a structural diagram and essential design parameters. The integration of operations within the module determines its adaptability to new processes, while imposing constraints that influence the configuration of components and control systems. It is essential to accurately define the functional purpose of the module and establish its specifications during the conceptual design phase.
