“…Concerning materials, a decisive competitive advantage of DEA technology is the predominant use of inexpensive and widely available (synthetic) polymers instead of expensive and limited available rare earth and copper materials as they are used for magnetic actuators. To achieve a good benefit at a low cost, product diversity also plays a crucial role [20,21]. Diversification of products to increase market share leads to an increase in product variety.…”

Thanks to their outstanding properties, in the last few years Dielectric Elastomer Actuators (DEAs) have increasingly attracted the interest of the scientific community and generated a surge in the effort devoted to their industrialization. Compared to conventional actuator systems, DEAs are based on inexpensive and widely available polymeric materials, which make them potentially attractive from a market perspective. However, DEA systems with a given layout and dimensions have a fixed force-stroke response that is only suitable for a specific load profile. This leads to a wide variety of designs combined with small production volumes and high costs, limiting the competitive advantage. This work addresses this issue by proposing a combination of DEA systems with compliant scissor linkage transmission mechanisms, which provide linear stroke and force scaling and simultaneously maintain performance optimization by leaving the convertible energy density of the DEA unaffected. For this purpose, three systems are designed, based on a same strip-shaped DEA combined with inclined buckled beam biasing mechanisms. Two of the systems are coupled with scissor linkages that offer transmission ratios of 3:1 and 1:3, respectively, to adapt the system to different load profiles. The system design is explained in detail, and the functional principle is validated through experiments.

“…This is achieved by a well guided combination of design, development, deployment and validation of solution in iteration and appropriate for the individual context or situation [20,21]. There appears not to be a consensus on what lean development principles are [8]. While some principles target lean for improved user experience [11], others target software development [27] and a lean development framework [7].…”

Abstract. [Context and motivation:]As a relevant and viable research methodology that addresses the development and empirical investigation of new artifacts, design science research (DSR) has gained traction in the requirements and software engineering research community over the past decade.[Question/Problem:] In this paper, we deliberate the synergies between the lean mindset and DSR, and explore the application of lean development approaches in the planning and execution of software and requirements engineering research projects. [Principal idea:] The widespread adoption of lean approaches in many business and technology practices today provides the impetus to explore their application in the context of software and requirements engineering empirical research. Toward this, we offer a review of key principles underlying the lean mindset and provide an overview of the typical processes followed in DSR research projects. Subsequently, we reflect the potential for lean development approaches to facilitate DSR projects. [Contribution:] We propose a conceptual framework that integrates lean principles with DSR phases and outputs, and we aim to inspire future discussion on the application of the lean mindset in the planning and execution of empirical research projects.

“…However, diversification of products results in an increase in product variety. Hence, common part concepts for the reduction of part variants as well as production line approaches aim at reducing development, production and administration costs while maintaining a similar benefit level to increase the competitiveness of a new product on the market [13,14].…”

Dielectric Elastomer Actuators (DEAs) are known for their outstanding properties such as low weight, high energy density and self-sensing capability. Compared to conventional magnetic actuators, they are manufactured from generally inexpensive and widely available polymer materials, making the technology particularly attractive for developing actuator systems that are potentially low-cost and serve a wide range of applications. This advantage can be further enhanced by developing scalable and standardized system designs that use identical parts in order to reduce product variation and enable high volumes in a mass production process. Following this approach, this paper introduces a low-profile and compact linear actuator design, which provides a configurable force and stroke transmission in order to serve different load-profiles without changing shape and dimension of the DEA itself. The design is based on rectangular-shaped, in-plane operating DEAs coupled to a unibody linkage mechanism, which is likewise flat and based on compliant joints and rigid links. A negative rate stiffness mechanism enables to increase the performance output of the actuator system in terms of cyclic converted energy in quasi-static operation. By configuring the lever ratios of the input and output sides accordingly, it can either behave stroke-magnifying or force-magnifying. Thus, as an example, a system with negative and one with positive transmission ratio are realized and characterized with respect to their force and their stroke behavior.
