Companies producing Robot-Like Systems (RLS) must increase efficiency in design and production in order to stay competitive in the international market. Such RLS range from small SCARA robots to entire production facilities. Very different systems for similar tasks are published in research or offered in the market. A clear path to an optimal configuration for a given task is apparently not available to the engineer. This indicates that the gear drives of such RLS and their integration with automation technology are still insufficiently researched, and their efficient design poses significant challenges for the industry. This paper identifies and provides a concise overview of requirements and challenges in the context of drives for such RLS. Building on this overview, suggestions are made for the future course of action in research.

Hydrogen bond (HB) chemistry, a pivotal feature of aqueous zinc-ion batteries, modulates electrochemical processes through weak electrostatic interactions among water molecules. However, significant challenges persist, including sluggish desolvation kinetics and inescapable parasitic reactions at the electrolyte-electrode interface, associated with high water activity and strong Zn 2+ -solvent coordination. Herein, a targeted localized HB docking mechanism is activated by the polyhydroxy hexitol-based electrolyte, optimizing Zn 2+ solvation structures via dipole interaction and reconstructing interfacial HB networks through preferential parallel adsorption. By combining in situ spectroscopic characterizations with theoretical calculations, we elucidate the dynamic evolution of localized HB networks, which enhance Zn 2+ deposition kinetics and homogeneity, suppress water-induced side reactions, and mitigate vanadium framework collapse. Our findings support that the targeted HB docking strategy facilitates fast interfacial ion transport kinetics and enables high reversibility, with a substantially prolonged symmetric cell lifespan exceeding 5000 h. This work markedly advances the efficient and reversible zinc-based batteries.

Modeling and Analyzing Cycle Networks in product-Service System development using System Dynamics

The development of product-service systems is affected by a large number of influences. These influences often show a cyclic character. The management of these cyclic influences reveals great potential for improving the product-service system development process. Knowledge about influences and their interdependencies supports the prediction of future changes and is highly valuable for planning. A core challenge is the high degree of dependencies between the different cycles. In this work, we show how to model and analyze cycles with interdependencies using system dynamics by extending a case study of former research. A previously developed cycle network is adjusted and a system dynamics model of the resulting cycles and their interdependencies is implemented. This enables a mathematical analysis and comprehension of the cycles within the network, supporting the understanding of the future behavior of cyclic influences and anticipating their potential effects. We introduce a replacement for the sigmoid function, which is frequently used to model cycles, but not suitable to include dependencies. The results emphasize the feasibility and benefits of a quantitative analysis. Though the model needs to be adjusted for specific use cases, the created network can serve as a framework for analyzing the development process of product-service systems and support deeper understanding of the interdisciplinary interdependencies.

In XXZ chains, spin transport can be significantly suppressed when the anisotropy in the chain and the bias of the dissipative driving are large enough. This phenomenon of negative differential conductance is caused by the formation of two oppositely polarized ferromagnetic domains at the edges of the chain. Here we consider the effect of a non-uniform, or disordered, magnetic field. We show that, while in general disorder reduces the current, in the regime of negative differential conductance disorder can enhance currents. This effect is limited and more pronounced in shorter spin chains. We consider different types of disorder distributions: uniform, algebraic and dichotomous. Analyzing in detail the effects of dichotomous disorder we find a resonant behavior with peaks of currents related to avoided crossings in the energy spectrum of the spin chain. Furthermore, by studying the effect of all possible configurations of the magnetic field, we find a configuration which results in a very strong spin current rectification, thus turning the spin chain into an effective diode.

Sequential Updating of Quantitative Requirements for Increased Flexibility in Robust Systems design

In early development stages of complex systems, interacting subsystems (including components) are often designed simultaneously by distributed teams with limited information exchange. Distributed development becomes possible by assigning teams independent design goals expressed as quantitative requirements equipped with tolerances to provide flexibility for design: so-called solution-spaces are high-dimensional sets of permissible subsystem properties on which requirements on the system performance are satisfied. Edges of box-shaped solution spaces are permissible intervals serving as decoupled (mutually independent) requirements for subsystem design variables. Unfortunately, decoupling often leads to prohibitively small intervals. In so-called solution-compensation spaces, permissible intervals for early-decision variables are increased by a compensation mechanism using late-decision variables. This paper presents a multi-step development process where groups of design variables successively change role from early-decision to late-decision type in order to maximize flexibility. Applying this to a vehicle chassis design problem demonstrates the effectiveness of the approach.

Transition metal chalcogenides exhibit broad application prospects in the energy sector depending on their high energy density and cycling stability. However, the issue of internal stress regulation within them is seriously neglected. Herein, we explore a novel cathode material for the first time and innovatively propose a stress release strategy driven by a multiple interface structure and dual-ion insertion to achieve superior energy storage behavior. We have designed a system with multi-interfaces Cu 4 SnS 4 cathode and APC-LiCl electrolyte to validate the rationality of our thought. Finite element simulations directionally demonstrate that dual-ion insertion and the multi-interface structure possess the capability to alleviate stress in many directions and exhibit exceptional wettability, thereby maintaining structural integrity from a mechanical perspective and significantly enhancing ion diffusion capabilities. Ex-situ characterizations and theoretical calculations comprehensively analyze the reaction mechanisms during magnesiation/lithiation processes, confirming the necessity of regulating internal stress and reaction kinetics. The proposed stress relief strategy not only provides inspiration for developing cathode materials with superior performance and durability but also opens a new path for driving technological innovation and industrial upgrading in the energy fields.

With the rapid advancement of 5G communication, artificial intelligence, and high-performance computing technologies, microelectronic devices are evolving towards higher integration, miniaturization, and power density, making thermal management a critical bottleneck for performance enhancement. Ultra-thin flat plate heat pipes (UTFP-HPs), owing to their high-efficiency heat dissipation characteristics and ultra-thin structure, emerge as promising candidates for such applications. Based on the electrodeposition technology, this study innovatively designs wick structures under various electrodeposition parameters and applies them to UTFP-HPs, through experimental research on its performance and mechanism. The results demonstrate that the wicks with different parameters display favorable capillary performance. Specifically, CC-18-160 can climb to the top of 90 mm within 84 s, IC-24-160 can reach the top in 56 s, and interestingly, IC-22-180 after undergoing oxidation corrosion merely requires 46 s to ascend to the top. Then the wicks are used to fabricate UTFP-HPs with a thickness of 0.5 mm. After conducting experimental tests under a variety of heat dissipation conditions, it was discovered that the maximum heat transfer capacity is 9 W, the minimum thermal resistance is 0.544 °C/W, and the equivalent thermal conductivity is 9196 W/m·K, which provides new insights for dynamic thermal optimization in electronic devices.

After a century of relative stability of the electricity industry, extensive deployment of distributed energy resources and recent advances in computation and communication technologies have changed the nature of how we consume, trade, and apply energy. The power system is facing a transition from its traditional hierarchical structure to a more deregulated model by introducing new energy distribution models such as peer-to-peer (P2P) sharing for connected communities. The proven effectiveness of P2P sharing in benefiting both prosumers and the grid has been demonstrated in many studies and pilot projects. However, there is still no extensive implementation of such sharing models in today’s electricity markets. This paper aims to shed some light on this gap through a comprehensive overview of recent advances in the P2P energy system and an insightful discussion of the challenges that need to be addressed in order to establish P2P sharing as a viable energy management option in today’s electricity market. To this end, in this article, we provide some background on different aspects of P2P sharing. Then, we discuss advances in P2P sharing through a systematic domain-based classification. We also review different pilot projects on P2P sharing across the globe. Finally, we identify and discuss a number of challenges that need to be addressed for scaling up P2P sharing in the electricity market followed by concluding remarks at the end of the paper. © 2020, CC0.

In the frame of space development projects, system design has to cope with large sets of requirements that are dependent from each other. The complexity becomes even higher since interdependencies often have a multidisciplinary character. The overall system complexity makes it difficult for design teams to intuitively understand the interactions of each physical domain not to mention the interdependencies of analyses and tasks. Dependency Structure Matrix (DSM) methods are used to represent the information flow of couplings as well as explore "what-if"scenarios in the sense of trade-offi. Graphical representations of interdependencies allow the designers to deliberately vary couplings. In this paper we demonstrate a successful application of DSM methods for the design of the Wide Field Imager, a payload instrument on board ESA ATHENA. © 2019 Lehrstuhl für Produktentwicklung und Leichtbau.
