Integrated Design Analysis for Product Simplification

A systematic methodology is presented for product structure simplification through an integration of Design for Manufacture and Assembly (DFMA) with the Theory of Invention Problem Solving (TRIZ). A new functional model is combined with a selection of TRIZ problem solving tools that are identified as effective in product structure simplification. DFMA analysis is used to evaluate alternative concepts. Application of the combined approach is illustrated through a case study of a heavy duty stapler.     

Evolutionary product line design balancing customer needs and product commonality

Product lines need to constantly evolve in response to market and technology changes. The diverging forces from marketing and engineering entail an intricate balance between satisfying changing customer needs and maintaining commonality in product platforms. This paper reports an evolutionary approach for product line design. Discrete choice analysis and product commonality indices are developed to evaluate the ‘fitness’ of a product line from marketing and engineering, respectively. Product line adaptation is formulated as a multi-objective optimization problem, whereby a solution framework based genetic algorithms is developed and implemented with a case study of notebook product line design.

Platform differentiation plan for platform leverage across market niches

This paper presents a methodology of proposing a platform differentiation plan (PDP) to provide a platform leverage strategy across market niches. PDP is designed to provide a consistent balance between mutual differentiation and components sharing for the leveraged platforms at the early product planning stage. Two indices, i.e. differentiation index (DI) and commonality opportunity index (COI), are presented to represent the dimensions of product platform differentiation and commonality, respectively. Through a case study of electronic test equipment (ETE), the usefulness of PDP for the platform leverage strategy across market niches is demonstrated.     

Optimum granularity level of modular product design architecture

In modular architectures, Design Structure Matrix (DSM) is used to cluster product components into modules with minimum interfaces externally and maximum internal integration between components. However, DSM is a flat connectivity map that does not capture the layered nature of the product structure. Hierarchical clustering (cladistics) is proposed to automatically build product hierarchical architecture from DSM. The resulting clustering tree represents product architecture while its depth represents its granularity. The optimum granularity level and number of modules are determined, indicating the potential product and process platforms. A case study of automobile body-in-white of 38 components is used to demonstrate the capabilities and superior results quality of the presented technique.

Customizability Index Based on Information Content

Developing product platforms has been recognized as an effective means to implement mass customization. This paper focuses on the customizability issue of design, that is, to evaluate the cost effectiveness of a design to be customized to meet individual customer needs. A customizability index is proposed to facilitate the analysis of customizability from both the customers and the manufacturer perspectives. It involves two dimensions. One is about the intrinsic nature of a design easy to be customized. The other is regarding the customer-perceived value of customization. The utility theory is introduced to model the customer-perceived value of each individual product feature. Conjoint analysis is introduced to explore customer preference for multiple product features. The customizability index is measured based on the information content metric. Customizability analysis manifests itself through the maximization of customer-perceived value while exploiting the potential of design to be customized specified by optimal customizability indices.     

Modularization as an enabler for cycle economy

Modularization proves to be a chance for increasing the use productivity of resources by enabling multiple usage phases sometimes even in different applications. A module configuration software tool has been developed for finding an appropriate modular product structure considering life cycle criteria. A mathematical model has been implemented to solve this multi-criterion optimization task. The application of the software tool is presented in a case study. The vision of developing and producing modular products in sustainable value creation networks is introduced.     

Knowledge Brokering for Assisting the Generation of Automotive Product Design

The aim of this paper is to present a pragmatic model for the systematic transfer of ideas and knowledge at the early stage of product design in a company environment. In using the model, the basic premise is not to build a new product ‘from scratch’ but to reuse existing ideas and knowledge from other objects and products developed previously. This new approach is called Knowledge Brokering (KB).The developed KB model consists of four sequential steps, which cover the collection and clustering of explicit design knowledge, the systematic learning process, retention and transfer of tacit design knowledge. The premises for using the KB model and case study results from the automotive industry on the advantages and limitations of the new approach are also described.     

Risk Quantification for New Product Design and Development in a Concurrent Engineering Environment

The challenges of product design and development in concurrent engineering are analysed. Bayesian Belief Networks are applied to map the relationships between risk events in a product's life-cycle. This approach enables the concurrency between risk items to be captured and the cumulative effects of dependencies between risk events to be determined. The inheritance of risks between different phases is modeled and quantified, which is impossible by traditional project management techniques. The combination of these factors has resulted in a user-interactive, unique dynamic risk management software package, which has been commercialised and deployed successfully by a major international manufacturer.     

Design for mass personalization

With pervasive connectivity of the Internet, personalization has become increasingly accepted for digital products. As opposed to customization, which emphasizes on meetings explicit requirements of defined market segments, personalization aims at effectively and efficiently satisfying individual needs. By considering customers as individuals, implicit characteristics such as personal taste, traits, innate needs and experience become important integral parts of product design. This new dimension for design opens up many new research issues. Design for mass personalization (DFMP) aims at effectively and efficiently satisfying customers as individuals by offering personally unique products with positive user experience. To this end, design is approached through the formulation of a product ecosystem based on a design platform and active customer participation.     

A novel paradigm for managing the product development process utilising blockchain technology principles

The product conceptualisation, design and manufacturing phases are becoming increasingly complex, since more available resources, stakeholders and sophisticated technologies are involved during product development. The exchange and management of product-related information is often a challenging task, affecting significantly the intellectual property protection process as well as the distinction of roles among stakeholders. This paper proposes a conceptual framework that utilises blockchain technology principles for managing product development information and processes with the goal of providing new approaches to extending the functionality of product data management systems. A test case focusing on products developed with additive manufacturing technologies is presented.     

Modular design for increasing assembly automation

Modular design can address the need for a high number of product variants and further allow a higher degree of automation in the assembly line. A framework is developed for the simultaneous modular product design and the design of automated manufacturing system. Product designs are optimized for automation using Design Structure Matrix and Modular Function Deployment. Alternative production systems are designed and accessed based on the analysis of assembly steps hierarchically. The implementation of the framework on the design of a production system for furniture assembly, able to handle multiple variants with a large number of components, is demonstrated.
