Undoubtedly, motor vehicles are among the most important, yet difficult to maintain and environmentally damaging consumer products on the planet. In light of the ongoing climate change discussion, sustainability considerations are currently taking a more prominent role in material selection decisions for automotive applications. This paper presents a new sustainability evaluation methodology for computing the potential benefits of using lighter materials, such as aluminum, in auto body applications, through a “Sustainability Scoring” method. When evaluating the “level of sustainability” built in any product, several major contributing factors (sustainability elements) need to be taken into consideration. Six major integral sustainability elements considered in this work are: product’s environmental impact, societal impact, functionality, resource utilization and economy, manufacturability and recyclability/remanufacturability. Each of these elements has corresponding sub-elements and influencing factors which are categorized as having varying levels of importance to the product. The paper compares the use of aluminum with the traditional use of steel alloys in a given automotive application using the newly developed comprehensive sustainability scoring method by considering all sustainability elements and sub-elements associated with a vehicle over its total life-cycle.

Design Concepts

Digital prototypes (DPs) allow designers to communicate design concepts to users by rendering physical characteristics of the concepts. To enhance user understanding of the concepts, it is important that the users be able to make better estimates of the values of the characteristics. Correctness of the estimates can depend on two crucial factors: the ability of DPs to render the physical characteristics and the way the DPs are used to communicate the physical characteristics. However, little attention has been paid to the latter. A DP can be used in different ways, e.g., it can be projected on different backgrounds, or be manipulated using different input/output devices. Hence, it is important to identify an effective way of using DPs, via an assessment of the effectiveness of various ways. This paper introduces a methodology for evaluating the effectiveness of communication of physical characteristics to users using DPs. The methodology is used to assess the degree to which users can correctly and quickly estimate the values of the characteristics through interactions with DPs. Such assessments are then analyzed with statistical methods and hypothesis tests to reveal the effectiveness. To validate the proposed methodology, the size of hand-held electronic consumer products, such as smartphones, is considered in a case study. In the study, the effectiveness of two communication setups is evaluated. The same DP is used in both setups, while the environments and input devices are different. The experimental results show that the evaluated effectiveness can reflect how successful the setups are, and can help select the best way of using the DP, i.e., by providing a better environment, a better input device, or a combination of both.

Automated Tool

Design engineers need an automated tool to effectively analyze the ease of assembly & disassembly of the subassemblies and the innovative products they create. A good assembly design makes it easier to service, easier to repair and maintain. Due to current environmental regulations the designers are forced to think about the life cycle of a product, recycling and reuse aspects of the products from the very beginning. This creates an environment for efficient implementation of design for manufacturing tools and techniques. A New Design for Assembly / Disassembly (DFA/DFD) Evaluation methodology explained here enables the designer to review the design for assembly and disassembly difficulties by considering several contributing factors and their importance to successful product creation. The technique is based on the criteria of “Rating Factors”. A spreadsheet format is used to create the front end interface for the user and to include all the influencing factors. The major parameters considered for the study are access, tool, task, re-use, removal, recyclability. Since the product maintenance is an important factor additional maintenance related issues such as spare parts, waiting time, priority and cost are considered as rating factors. The new methodology was compared with other existing techniques and found to be valid and useful to manufacturing industries.

Honeywell Aerospace, along with Applied Physics Systems, Sunnyvale, CA, has developed 300°C capable directional sensor technology in support of the U.S. Department of Energy's Enhanced Geothermal Technologies initiative. The development has culminated in fabrication of custom silicon-on-insulator IC's, fabrication and assembly of ceramic hybrid electronics, and the directional sensors, accelerometers and flux-gate magnetometers, all capable of operating at temperatures up to 300°C. The sensors and supporting hybrid electronics have been integrated into a non-magnetic chassis designed for inclusion in a directional drilling bottom-hole assembly. This paper presents the technology approach, material selection decisions, processing techniques, final sensor and electronics configuration, and initial testing of the integrated directional module.

Abstract Additive Manufacturing (AM) concerns all classes of materials – polymers, metals, ceramics and glasses as well. For this reason, AM is in the focus of material scientists from all branches. Leaders of the industry realize that the possibilities of 3D printing are endless, and that these possibilities need ways and means to be taken full advantage of. Today, aerospace engineers are using the fused deposition modeling (FDM) method for rapid prototyping, part manufacturing, and tooling. They are followed by leaders and engineers from industry (industrial machines, motor vehicles, consumer products, medical/dental) but also from academic institutions and government/military.
