Production using modular architecture can not only shorten the product development cycle and improve efficiency of development, but also facilitate upgrading a product’s main functions recycling materials. However, mechatronic products are plagued by various problems, such as greater difficulty in longer cycles due to their large numbers parts with intricate internal relationships. existing design method still faces problems when dealing products. The structure mechanical electrical is very complex, which conducive establishment model, complex structural models lead low poor accuracy module identification. Therefore, we propose an integrated division for based on core part hierarchical clustering non-core association analysis. Firstly, screening used simplify model reduce modeling. Then, parts, corresponding matrix (DSM) established. Secondly, algorithm obtain scheme different levels products, optimal obtained through evaluation modularity rationality analysis structure. Finally, strength between modules, classified into final modularization obtained. A case study demonstrates feasibility proposed electric bicycle.

Performance Gain of Collaborative Versus Sequential Motion in Modular Robotic Manipulators for Pick-and-Place Operations

Machines, Journal Year: 2025, Volume and Issue: 13(5), P. 348 - 348

Published: April 23, 2025

With the increasing demand for efficiency and profitability in industrial applications, modularity offers significant advantages such as system reconfiguration, reduced acquisition costs, enhanced versatility. However, achieving compatibility across multi-vendor modular systems remains a challenge, particularly motion control. This study focuses on improving control sensing performance, partly using open-source tools to enhance performance systems. In systems, effective coordination between modules is crucial; without it, operations are constrained sequential execution, limiting efficiency. paper quantifies benefits of collaborative compared mechatronic pick-and-place operations. The experimental validation, conducted robotic manipulator mounted linearly sliding platform, demonstrates substantial improvement. results show time savings 36% 52% an approximate 35% reduction energy consumption, highlighting potential improved productivity sustainability automation solutions.

Abstract Decomposing product design into multiple granularities is an effective strategy to implement complex design. Tacit knowledge (TDK), adhering designers’ experience and intuition, plays essential role in the at various granularities, but it difficult acquire reuse due its implicity. Aiming this issue, a graph-based multi-granularity TDK framework for presented. First, issue-solving oriented graph (DSKG) model employed indirectly capture TDK, where result data are represented as solution nodes issues that refine relation edges. An improved ontological concept designed schema of DSKG represent on functions, behaviours, structures products. Afterwards, supports two modes, i.e., top–down bottom–up design, captured reused create context predict solutions. embedding prediction both while creation achieved distinctively. In process starts from requirements then gradually downward refines solutions different with breadth-first strategy, which naturally creates continuous context, until moving detailed target commonly isolated specific fine-grained granularity.

Reconfigurable manufacturing system (RMS) is designed to meet dynamic market demands by changing function and capacity which built around a product family. Therefore, the foundation for success of designing RMS lies in precise family formation. This paper proposes novel formation method based on optimal resource sequence. Instead clustering products only process similarity, derives sequence from sharing resources. Then Produce-Process-Resource similarity coefficient used hierarchical clustering.
