JOURNAL ARTICLE

Baxter WL, childs PRN, 2017, Designing Circular Possessions, The Routledge Handbook of Sustainable Product Design, Editors: Chapman

The notion of possession is one of the most fundamental concepts that guide everyday behaviour. Paradoxically, it is often poorly understood. This is particularly true in a circular context where consumer interactions with possessions are being altered and in some cases redefined. Thus, an understanding of possession serves as a useful, if not necessary, prerequisite to designing circular products, services and systems. This chapter explores the idea of possession: what it is, how an object becomes one and why it is important for the circular economy. Possession is understood through a human-centred lens that considers the consumer’s state of mind towards and relationship with an object. A state of possessiveness can be attained for material or immaterial objects and for objects that may or may not legally belong to the person. The discussion is presented within a design framework that discusses the motives and routes that lead to the state of possession. This framework is substantiated by looking at affordance principles and paths associated with possession. Each section includes a theoretical discussion as well as practical examples and insights that can be incorporated into the product design process itself. This chapter aids in understanding interactions relevant to the circular economy such as the maintenance and care that comes with object attachment and adoption of access-based consumption models. Understanding and designing for these desired interactions should be the first priority of designers followed by an establishment of laws, regulations and policies to support them.

Chen L, Shi F, Han J, Childs PRNet al., 2017, A network-based computational model for creative knowledge discovery bridging human-computer interaction and data mining

Copyright © 2017 ASME. As a branch of computational creativity, Creative Knowledge Discovery (CKD) aims to search for valuable, previously unknown, or ignored, relationships between concepts, and create new patterns by taking advantage of existing patterns or by analogy to patterns in other domains. Data mining has been widely used in CKD research. However, most proposed mining algorithms lack a theoretical basis for computational creativity due to their origins in traditional knowledge discovery in databases (KDD), which stymies novelty. In addition, integration of human-computer interaction (HCI) is often overlooked for assisting discovery of creative knowledge despite the human end user possessing problem solving intelligence. To address these issues, a network-based computational model bridging humancomputer interaction and data mining is proposed arising from an initial investigation on the theoretical basis of computational creativity. A corresponding creativity evaluation methodology, Multi-dimensional In-depth Long-term Case studies (MILCs) is also introduced. In order to evaluate the proposed model, a web tool called B-Link has been developed. Longitudinal interviews and a questionnaire survey have been conducted by applying the MILCs evaluation method. The success of finding novel items and obtaining inspiration in interviews as well as the positive survey rating results of all five creativity metrics have suggested that B-Link is able to guide thinking processes and aid creative knowledge discovery effectively, which demonstrates the capability of the proposed network-based computational creativity model integrating human-computer interaction and data mining.

Han J, Park D, Shi F, Chen L, Childs PRNet al., 2017, Three driven approaches to combinational creativity, Pages: 259-268, ISSN: 2220-4334

Creativity is a crucial element of design, and a human attribute that has aroused significant attention. However, few studies have focused on the factors and motivations that drive creativity. The aim of the study is to investigate the driving forces behind combinational creativity for developing original creative products. We propose three driven approaches to combinational creativity, the problem-driven approach, the common-driven approach, and the inspiration-driven approach, based on previous research projects on design process, design strategy, and design cognition. A test involving two-hundred practical products has been conducted to validate the three approaches by means of expert evaluation. The test results have indicated the validity of the three driven approaches. The three approaches proposed in this study have provided an understanding of how combinational creativity is driven in design, which could lead to a better comprehension of human creativity in design. The study enables indication that the three approaches can be applied by designers to aid in the production of creative designs for and in resource-limited societies.

Hu Z, Rao C, Tao C, Childs PRN, Zhao Yet al., 2017, A case-based decision theory based process model to aid product conceptual design, Cluster Computing, Pages: 1-18, ISSN: 1386-7857

© 2017 Springer Science+Business Media, LLC In new product development, the rapid proposal of innovative solutions represents an important phase. This in turn relies on creative ideas, their evaluation, refinement and embodiment of worthwhile directions. This study aims to describe a CBDT based process model for product conceptual design that concentrates on rapidly generating innovations with the support of decision-making rationale. Case-based decision theory (CBDT), derived from case-based reasoning, is applied in this paper as a core method to aid design engineers to make an informed decision quickly, thus accelerating the design process. In the process of utilizing CBDT to support a decision, as for the similarity function, the proper value assignment methods to the selected attribute set for calculation are discussed. In order to assist with innovative solution, aspects of the theory of inventive problem solving (TRIZ) are integrated into the case-based reasoning process. Accordingly, a CBDT-TRIZ model is developed. Quality-function deployment is used to translate customer wants into relevant engineering design requirements and thus formulating the design specification. Image-Scale is used to offer an orthogonal coordinates system to aid evaluation. Finally, a case study is used to demonstrate the validity of the proposed process model based on the design of a cordless hand-tool for garden and lawn applications.

Headlines Heat constitutes about half of total global energy demand. Solar heat offers key advantages over other renewable sources for meeting this demand through distributed, integrated systems. Solar heat is a mature sustainable energy technology capable of mass deployment. There is significant scope for increasing the installed solar heat capacity in Europe. Only a few European countries are close to reaching the EU target of 1 m2 of solar-thermal installations per person. One key challenge for the further development of the solar-thermal market arises from issues related to the intermittency of the solar resource, and the requirement for storage and/or backup systems. The former increases investment costs and limits adaptability. An analysis of EU countries with good market development, suggests that obligation schemes are the best policy option for maximising installations. These do not present a direct cost to the public budget, and determine the growth of the local industry in the long term. Solar-thermal collectors can be combined with photovoltaic (PV) modules to produce hybrid PV-thermal (PV-T) collectors. These can deliver both heat and electricity simultaneously from the same installed area and at a higher overall efficiency compared to individual solar-thermal and PV panels installed separately. Hybrid PV-T technology provides a particularly promising solution when roof space is limited or when heat and electricity are required at the same time.

REPORT

Shi F, Chen L, Han J, Childs Pet al., 2017, A Data-Driven Text Mining and Semantic Network Analysis for Design Information Retrieval, Journal of Mechanical Design, Transactions of the ASME, Vol: 139, ISSN: 1050-0472

With the advent of the big-data era, massive information stored in electronic and digital forms on the internet become valuable resources for knowledge discovery in engineering design. Traditional document retrieval method based on document indexing focuses on retrieving individual documents related to the query, but is incapable of discovering the various associations between individual knowledge concepts. Ontology-based technologies, which can extract the inherent relationships between concepts by using advanced text mining tools, can be applied to improve design information retrieval in the largescale unstructured textual data environment. However, few of the public available ontology database stands on a design and engineering perspective to establish the relations between knowledge concepts. This paper develops a WordNet focusing on design and engineering associations by integrating the text mining approaches to construct an unsupervised learning ontology network. Subsequent probability and velocity network analysis are applied with different statistical behaviors to evaluate the correlation degree between concepts for design information retrieval. The validation results show that the probability and velocity analysis on our constructed ontology network can help recognize the high related complex design and engineering associations between elements. Finally, an engineering design case study demonstrates the use of our constructed semantic network in real-world project for design relations retrieval.

Shi F, Chen L, Han J, Childs Pet al., 2017, Implicit knowledge discovery in design semantic network by applying pythagorean means on shortest path searching

© 2017 ASME. With the advent of the big-data era, massive textual information stored in electronic and digital documents have become valuable resources for knowledge discovery in the fields of design and engineering. Ontology technologies and semantic networks have been widely applied with text mining techniques including Natural Language Processing (NLP) to extract structured knowledge associations from the large-scale unstructured textual data. However, most existing works mainly focus on how to construct the semantic networks by developing various text mining methods such as statistical approaches and semantic approaches, while few studies are found to focus on how to subsequently analyze and fully utilize the already well-established semantic networks. In this paper, a specific network analysis method is proposed to discover the implicit knowledge associations from the existing semantic network for improving knowledge discovery and design innovation. Pythagorean means are applied with Dijkstra's shortest path algorithm to discover the implicit knowledge associations either around a single knowledge concept or between two concepts. Six criteria are established to evaluate and rank the correlation degree of the implicit associations. Two engineering case studies were conducted to illustrate the proposed knowledge discovery process, and the results showed the effectiveness of the retrieved implicit knowledge associations on helping providing relevant knowledge from various aspects, and provoking creative ideas for engineering innovation.

The Innovation Design Engineering (IDE) double masters programme, run jointly by the Royal College of Art and Imperial College London is now in its 34th year. Originally called Industrial Design Engineering the aim of the pro-gramme was to provide an educational pathway for taking graduate engineers and produce a new type of industrial designer. The two-year full-time programme in-volves a series of themed but student-directed projects in the first year, prior to major group and solo projects in the second year. This chapter introduces the orig-inal purpose of the programme, documents some of the transitions as well as providing a description of the current format of the programme, with a particular focus on addressing the needs of industry and those of individual students and graduates, and the sometime tensions between these. The Innovation Design Engi-neering is characterised by a ‘borrowed discourse’ with no distinct disciplinary language owned by the community at the moment. This is manifest in the exten-sive engagement by the students in their collaborations across the Departments and Research Centres at Imperial and their willingness to explore diverse innova-tion spaces. Traditionally graduates have gained subsequent employment in corpo-rations and design consultancies. The last five years has seen a significant shift with the greater proportion of graduates setting up their own businesses and con-sultancies on completion of the programme.
