Realizing Product‐Packaging Combinations in Circular Systems: Shaping the Research Agenda

Recent years have shown a shift in the focus of sustainable development from eco‐efficiency (minimizing negative impacts) towards eco‐effectiveness (optimizing positive impacts). Currently, a focus on circular models can be identified; Cradle to Cradle and circular economy are main examples of such models. However, the current number and variety of models and tools focusing on circular systems are limited with regard to packaging development. This paper explores packaging development models and tools in relation to circular systems, in order to identify the current status of the circularity focus. A range of identified models and tools is structured into two categories (generative and evaluative tools) which cover three types (protocols, diagrams and evaluations). This is in line with the distinction between early and later phases of development and the cumulative nature of environmental lock‐in. Protocol‐type models and tools come in different forms, such as principles, guidelines and checklists (e.g. Cradle to Cradle and DfE). Aside from these, eight diagram‐type models are analysed, focusing on packaging development, sustainable development and sustainable packaging development. In contrast to generative design tools, evaluation‐type models and tools (e.g. LCA) are most useful in the later stages of development processes. Resulting from the analysis of the models and tools, three types of integration – integrated product‐packaging development, the cross‐functional integration of actors and the front‐end integration of sustainability considerations – are appropriate for the development of product‐packaging combinations for circular systems. This leads to an agenda which shapes research directions towards achieving this development. © 2016 The Authors Packaging Technology and Science Published by John Wiley & Sons, Ltd.     

A tool for meaning driven materials selection

There are several tools used in materials selection processes by designers. However, they are mostly engineering based tools, which are dominated by numerical (or technical) material data that is mostly of use in embodiment or detailed design phases of new product development. On the other hand, product designers consider certain aspects such as product personality, user-interaction, meanings, emotions in their material decisions. In this regard, existing tools and methods do not fully support designers in their materials selection processes. This paper describes the development of a new materials selection tool holding the idea of [meaning driven materials selection]. In addition, the paper consists of a study conducted to create data for a dummy application.     

PVD – Eine Erfolgsgeschichte mit Zukunft

PVD – A success story with a future PVD coatings in the range of a few nanometers up to some microns have become state of the art in engineering technology. PVD coatings can be found anywhere in our everday lives. They are used in data storage mediums such as CDs or DVDs. Car or architectural glasses are improved by thermal insulation coatings. A diffusion barrier is achieved via PVD coatings at food packaging. For decorative aspects sham jewelery and accessoires are coated as well as fittings. In the last three decades PVD coatings have been established in a variety of technical applications acquiring wear protection and/or friction reduction. First, coatings for tools have been developed, later on for components as well. So, in the past lots of experiences have been made not only in coating development, but likewise in methodical product design. By contrast, the surface has not yet been regarded as construction element. Here the knowledge is just at the beginning. The achieved performance of coated components can be improved drastically if the tribological system consisting of coating, substrate and intermediate material is designed for one single application with regard to the macro‐ and micro geometry. An exemplary application derived from the collaborative research center (SFB 442) “Environmentally friendly tribosystems” at the RWTH Aachen university is discussed. Results of fundamental research and their way into industrial applications are presented. The research development is reflected with regard to the development of the industrial PVD market. Regarding a process chain for the exemplary application the development method of surface technology is explained beginning with the production up to field testing of a new product.

Design Verification through virtual prototyping techniques based on Systems Engineering

The increasing offer of software tools for product development introduces methodological questions to design engineers in terms of the easiness of tool integration and design activities’ sequencing. Nowadays, Design Verification and Validation through prototyping techniques have been enriched with software solutions enabling virtual prototyping to take more product’s behaviors into consideration during analysis and simulation. It is the case of the Systems Engineering module in CATIA? V6 that proposes a sequential “Requirements–Functional–Logical–Physical Design” (RFLP) approach to link conceptual design activities with 3D-models and simulation. Since some practitioners traditionally use these concepts, this article presents an analysis, based on action research, to evaluate the Design Verification activities as well as the tools integration offered by the new Product Lifecycle Management vision of CATIA? V6. The analysis enabled authors to refine and propose a model’s nature-dependent design method, enriched from the basic RFLP concept. Additionally, the presented results also showed the benefits of using integrated approaches when designing complex products, represented in a case study on virtual Design Verification of an automotive sub-system.

State of the Art on Micromilling of Materials,a Review

The trend towards miniaturization has increased dramatically over the last decade, especially within the fields concerned with bioengineering, microelectronics, and aerospace. Micromilling is among the principal manufacturing processes which have allowed the development of components possessing micrometric dimensions, being used to the manufacture of both forming tools and the final product. The aim of this work is to present the principal aspects related to this technology, with emphasis on the work material requirements, tool materials and geometry, cutting forces and temperature, quality of the finished product, process modelling and monitoring and machine tool requirements. It can be noticed that size effect possesses a relevant role with regard to the selection of both work material (grain size) and tooling (edge radius). Low forces and temperature are recorded during micromilling, however, the specific cutting force may reach high values because of the ploughing effect observed as the uncut chip thickness is reduced. Finally, burr formation is the principal concern with regard to the quality of the finished part.
