Sustainable Product

Product variety and improvements are the most important issues of today’s product development. Product family engineering is considered to be an effective approach to create new products that apply variability with decreased costs and time. However, given the environmental considerations, this study proposed sustainable product family planning which is a systematic design framework of product function; structure and lifecycle options (i.e. reduce, reuse and recycle). First, relationships between the diverse customer needs, product’s technical attributes and physical architecture are analyzed. Based on the analysis, certain product family plan including a product model change plan, a general product structure model, technical specifications and lifecycle options of each product in the family are established. A life cycle simulation tool is then developed for 1) easy building of various production strategies, product use scenarios and market competition cases, etc.; and 2) environmental and economic evaluations of the product family plan. A case study of personal computers (PCs) product family planning demonstrates an implementation of the proposed methods.

Modular Structures

Environmental issues require a new manufacturing paradigm because the current mass production and mass consumption paradigm inevitably cause them. We have already proposed a new manufacturing paradigm called the “Post Mass Production Paradigm (PMPP)” that advocates sustainable production by decoupling economic growth from material and energy consumption. To realize PMPP, appropriate planning of a product life cycle (design of life cycle) is indispensable in addition to the traditional environmental conscious design methodologies. For supporting the design of a life cycle, this paper proposes a life-cycle simulation system that consists of a life-cycle simulator, an optimizer, a model editor, and knowledge bases. The simulation system evaluates product life cycles from an integrated view of environmental consciousness and economic profitability and optimizes the life cycles. A case study with the simulation system illustrates that the environmental impacts can be reduced drastically without decreasing corporate profits by appropriately combining maintenance, reuse and recycling, and by taking into consideration that optimized modular structures differ according to life-cycle options.

Sustainable Product

Sustainable product design plans the entire life cycle of a product from its raw material selection, conceptual and structural formation, manufacturing processing, and usage to its end-of-life, reuse, and recycle. The product design needs the sustainable knowledge and proper tools. Current computer-aided design systems are insufficient to represent complex relationships of product functions, structures and life cycle options. It is required for design tools to support product life cycle planning with multi-objective optimal solutions. In this paper, our experience in design of a wheelchair is used as an example to discuss the need of design tools. The aim is to define ideal tools for design of sustainable products.

The Cost

The cost estimation of a product’s life cycle is a key factor in the product design process. The research is based on an innovative model of artificial neural networks (ANNs) compared to a parametric estimation. Introducing modern elements of information technologies in the area of cost estimation for a production company is a vital element of its sustainability in the era of Industry 4.0. The presented modern product life cycle cost estimation tool in the form of ANN is a reliable source of forecast that is the basis for the product life cycle cost reduction program, which is a crucial element of sustainability. Research shows that ANNs are a viable alternative to parametric cost estimation. The percentage error between estimated and historical cost values is 8.05 times lower for ANN than for the parametric approach. ANN is an adequate cost estimation model for technologically complex products. The second contribution is using technical specifications required by the customer directly to estimate the cost of a product’s life cycle automatically. This can translate both into a reduction of the time needed to provide information to the client and the workload of engineers.

Single Material

Bio-inspired design, or biomimicry, is an approach to innovation that takes nature’s time-tested patterns, forms, functions, processes, and materials and uses them to develop engineering solutions. In this project we take inspiration from biological morphologies to develop new forms for semi-recyclable products. Biological systems exhibit multi-functionality from form, not necessarily material, which offers inspiration for product life-cycle management. The goal is to better understand the connection between form and function as found in nature to enable sustainable product design and enhance additive manufacturing processes. Through the application of bio-inspired design product recyclability is increased through minimization of material diversity while still achieving desired functions. One inspiring biological morphology that has been utilized across multiple biological kingdoms and in this research is variations in hardness and flexibility found in alternating layers that are used to provide strength, durability and protection. Another inspiring morphology considered in this research is the backbone of water-diving birds, which consists of an intricately braided spine with parallel holes along each side. These holes allow for shock absorbance and force dispersion. These multi-function forms have resulted in the redesign of a semi-recyclable product fabricated using additive manufacturing to create a product that is made from a single material yet still achieves all necessary functions. Key contributions of this research include approaches for additive manufacturing strategies such as material utilization that align with a product’s life cycle, thus increasing the recyclability of the product.
