A systematic technique for new product idea generation: the external brain

The author outlines a novel computer-based technique to generate ideas for new products. Essentially the technique uses the so-called Dialog databank, claimed to have access to 152 million units of information, to search for all publications in the database which combine a root concept and words such as idea, innovation, novelty, and so on. The computer can then be instructed to print out the titles of a restricted number defined by the searcher from each database accessed. The searcher can then study the contents of each publication at leisure. In principle other similar databanks can be used.
The technique is illustrated by two hypothetical cases: new uses for water and new uses for metal-powder technology.
The author claims that the technique will generate a large number of ideas in a short time at low-cost, can be used selectively (eg to search within a stated time-period), will link otherwise unrelated disciplines, and is well suited to brainstorming. The main drawbacks are that much of the information may be irrelevant, it cannot provide entirely new ideas though it can link existing concepts in a new way, and it cannot print out the total text from an identified source.     

Determinants of idea sharing in crowdsourcing: evidence from the automotive industry

Drawing on external ideas through crowdsourcing has become common practice for firms that seek to improve and extend their product portfolios. As these initiatives often address the users of products, it is essential for firms to recognize those attributes that determine these individuals' willingness to share their ideas. This study takes the example of the automotive industry to examine how three attributes of car drivers determine their sharing behavior – that is, altruism, psychological ownership of ideas, and trust in car manufacturers. Our findings suggest that trust and altruism strengthen idea sharing, while psychological ownership weakens it. Furthermore, we find that car drivers' perception of sharing‐related risk acts as an important boundary condition for these relationships.     

Toolkits for idea competitions: a novel method to integrate users in new product development

Research has shown that many innovations originate not in the manufacturer but the user domain. Internet-based toolkits for idea competitions (TIC) are a novel way for manufacturers to access innovative ideas and solutions from users. Idea competitions build on the nature of competition as a means to encourage users to participate at an open innovation process, to inspire their creativity, and to increase the quality of the submissions. When the contest ends, submissions are evaluated by an expert panel. Users whose submissions score highest receive an award from the manufacturer, which is often granted in exchange for the right to exploit the solution in its domain. Following the idea of evolutionary prototyping, we developed a TIC in cooperation with a manufacturer of sports goods. The TIC was launched as a pilot in one of the company's markets. Submissions were evaluated using the consensual assessment technique. The evaluation of this study provides suggestions for further research, but also implications for managers willing to explore TIC in their organization.     

A network perspective on idea and innovation crowdsourcing in industrial firms

Crowdsourcing has been attracting the attention of both academics and practitioners over recent years. The aim of this article is to contribute to the current body of knowledge on innovation in networked contexts by systematically analyzing various crowdsourcing configurations available to industrial firms. We first develop a categorization of crowdsourcing in industrial firms comprising four distinct configurations: internal crowdsourcing; community crowdsourcing; open crowdsourcing; and crowdsourcing via a broker. We then proceed to draw from the literature on industry networks to further deepen our understanding of how these four distinct configurations can contribute to business and innovation activities of a focal industrial firm. Specifically, we focus on the structural properties, nature of collaboration, and governance of crowdsourcing networks. This novel combination of crowdsourcing and network research delivers new insights that enrich current understanding on various options available to industrial firms operating in networked contexts to facilitate their innovation processes.     

Sketching by design: teaching sketching to young learners

Recent science educational reforms in the United States have prompted increased efforts to teach engineering design as an approach to improve STEM (Science, Technology, Engineering, and Mathematics) learning in K-12 classrooms. Teaching design in early grades is a new endeavor for teachers in the United States. Much can be learned from design teaching and research on K-12 design education outside of the US. The purpose of this study was to explore how students learn and use design sketching to support their learning of science and design practices. Researchers provided a treatment of design sketching instruction based on best practices of prior research finding (Hope in Des Technol Educ Int J 10: 43–53, 2005; Gustafson et al. J Technol Educ 19(1):19–34, 2007). A delayed treatment model was used to provide a two-group counterbalanced quasi-experimental design to compare an experimental group and comparison (delayed treatment) group results from (6) grade 3 classrooms. Researchers employed Hope’s Des Technol Educ Int J 10: 43–53, (2005) frame to organize sketching data for analysis. Findings from this study indicated that design instruction treatment did improve student’s design and communication practices, moving from using sketching as a container of ideas to the use of sketching as a form of design communication and to refine design ideas. Both the treatment and comparison groups improved sketching skills after treatment was provided to both groups. Sketching is a design practice that can also help student learn science concepts through the generation of mental models of conceptual understanding.     

Interplay of computer and paper-based sketching in graphic design

The purpose of this study is to investigate student designers’ attitude and choices towards the use of computers and paper sketches when involved in a graphic design process. 65 computer graphic technology undergraduates participated in this research. A mixed method study with survey and in-depth interviews was applied to answer the research questions. This result shows that sketches and computers as design tools help students generate ideas in the early stage of design. Students’ preferences to use sketches or computers differ, since each tool has its own advantages and disadvantages.     

Impact of text on idea generation: an electroencephalography study

Sketching is widely used as a creative tool, playing a significant role in industrial design. Designers commonly use sketching to generate and evaluate ideas, leading to subsequent development of the most promising ideas. The current study examined the use of text in the idea generation sketching process among novices and experts. The electrophysiological correlates of thought processes were measured using electroencephalography (EEG). The thought process involved in idea generation was coded according to working memory components, and sketches were scored. The results revealed that experts generated better quality ideas, using similar thought processes. Importantly, the use of text increased the number of creative elements in ideas with lower creative quality among both novices and seniors. Electrophysiological analysis revealed that EEG signals corresponded with this behavioral pattern. Novices showed an activation pattern of low creativity, and the use of text activates the right hemisphere. Overall, the results revealed that the quality of concepts stored in memory was associated with a difference in quality between experts and novices, and that text elicited a higher volume of diverse analytical thinking that helped broaden creative possibilities rather than improving creative quality.     

Collaborative learning in technological project design

The POWERTECH contest in Taiwan was established in an attempt to promote inventiveness and technology to elementary school pupils. The POWERTECH contest is designed as a collaborative learning system for project design. Project design is comprised of technical processes, which include the construction of an artifact and improvement of its functions. Thus, pupils learn scientific and technical knowledge through a collaborative design project. The purpose of the study was to examine how collaborative learning could be facilitated in technological project design, and whether and how pupils working collaboratively were able to share their design ideas. The study was carried out by analyzing the design portfolio compiled by a team of four elementary school pupils who were engaged in a collaborative design project that focused on making a robot rat for the POWERTECH contest. A portfolio analysis was used in this study to help researchers assess the actual collaboration process among the team members. The study indicated that collaborative learning in a contest facilitated the sharing of knowledge and resources among the team members. Furthermore, reflections essential for problem-solving among the team members were often raised during the design process. These reflections were also conducive to the reduction of mistakes during the contest.     

Line by line,part by part: collaborative sketching for designing

While sketching has an established role in professional design, its benefits and role in design education are subjects that invite research and opinions. We investigated how undergraduates studying to become design educators and textile teachers used sketching to generate and develop design solutions in a collaborative setting. The students were given an authentic design assignment involving three detailed tasks, one of which was 2D visualisation by sketching. Adopting a micro-analytical approach, we analysed the video-recorded visualisation session to understand how teams used sketching to collaborate and to generate and develop design solutions. To that end, we set three research questions: (1) What ways of collaborative working are reflected in actions of sketching? (2) In what ways do sequences of collaborative sketching contribute to designing? (3) What kinds of collaborative sequences of sketching advance designing? Our analysis identified three collaborative ways of sketching (co-ordinated, collective and disclosed) and confirmed that sketching is an important facilitator of mutual appropriation, adaption and adoption. Next, we identified three ways of contributing to designing, as well as three functions and six capacities for advancing designing. Our analysis shows that sketching can lead to invaluable advances in designing, although each team had its own way of using and benefiting from sketching. We further consider that the teams’ diverse sketching processes and rich content owed, at least in part, to the task structure and imposed constraints. We continue to see sketching as an important design tool, one among many.

A novel CAI system for space conceptualization training in perspective sketching

For many designers, freehand sketching is the primary tool for conceptualization in the early stage of the design process. However, current education on concept presentation techniques rarely emphasizes the construction of the most fundamental spatial unit, the cube. Incorrect construction of spatial units leads to disproportions that deviate from the common visual experience, and consequently slows down the design process. In addition, weak spatial cognition can be a problem when transferring sketches into orthographic drawings. To address these issues, this research focuses on the training of cube sketching techniques using both freehand skills and digital devices. Based on the station-point approach for two-point perspective drawings, this study developed a computer-assisted instruction (CAI) platform for beginners, with which users can practice freehand sketching for self-improvement. This platform provides instant corrective feedback to every freehand-sketched cube, thus promoting better learning outcome and more effective use of educational resources. Similar platforms have not yet been found in the field. The proposed system’s feasibility and practicality were evaluated through a series of teaching experiments. The results indicated that the proposed CAI system can improve students’ sketching accuracy by 19% after 6 weeks of instruction, and that the proposed system was found to be more effective than traditional pen-and-pencil instructions in advancing sketching techniques.     

From collaborative community to competitive market: the quest to build a crowdsourcing platform for social innovation

Crowdsourcing presents new opportunities to generate social innovation. However, many crowdsourcing social innovation initiatives struggle with turning their promising projects into sustaining platforms. We studied how to design crowdsourcing platforms for social innovation by building and examining a platform called travel2change. We illustrate a framework of crowdsourcing platform building blocks based on the evolution of our case study from a collaborative community to a competitive market. Thriving platforms have a clear purpose, they facilitate value‐creating interactions for well‐understood actors and build a valid business model. The insights reveal design principles to guide organizations that seek to leverage crowdsourcing for social impact.     

Customers' participation in product development through crowdsourcing: Issues and implications

This paper focuses on customers' participation in a product development process through crowdsourcing practices. Results from five case studies of consumer goods companies suggest that the implementation of crowdsourcing operations affects the components of an existing business model and requires rethinking the marketing function. Moreover, despite some organizational constraints and fears, crowdsourcing generates a win–win relationship, creating value for both firms and customers. However, the findings reveal two negative consumer reactions to crowdsourcing practices, i.e., feelings of exploitation and being cheated, that may jeopardize their success. The results suggest the need to establish an open business model based on crowdsourcing.     

Access regulation and geographic deployment of a new generation infrastructure

This paper addresses the impact of regulatory policy on levels of infrastructure deployment and derived welfare in the telecommunications sector. The model considers two potentially coexisting and partially competing technologies (the “old generation network” – OGN – and the “new” generation network – NGN). This framework allows us to show that the “regulation defining access charge in order to maximize infrastructure deployment” is strictly equivalent to the case in which “no regulation applies”. We also derive from the model that these two types of regulation induce higher social welfare, but lower numbers of NGN consumers, compared to the “ex post access prices” regulation. Finally, we show that the level of infrastructure deployment (as well as social welfare and number of NGN consumers) will be highest if both investment and access charge decisions are taken by the welfare maximizing regulator. This suggests that the social optimum will be achieved through a calls-for-tender process that includes deployment and access charge requirements.     

Factors for improving the level of knowledge generation in new product development

Globalization and other rapid changes in markets and technologies increasingly require companies to generate new knowledge in order to remain competitive. In order to innovate successfully, firms must generate knowledge faster than their rivals. This study develops and tests a conceptual model that focuses on how managerial controllable variables influence the level of knowledge generation in new product development. Based on literature and 'theory-in-use' field research in seven knowledge-intensive organizations, the authors developed research hypotheses and tested the hypotheses using data collected from 277 firms in high technology industries. The findings suggest that information technologies, organizational crisis, individual commitment, the R&D budget, and job rotation increase levels of knowledge generation, whereas lead user and supplier networks are negatively associated with the level of knowledge generation in new product development, and the influence of co-location of R&D staff is not significant.     

Use of social capital among Russian managers of a new generation

Dynamic changes in the Russian political economy during the 1990s led to a unique combination of low levels of social capital at the general (state) level and very high levels of social capital at the interpersonal level. This research uses the three dimensions of social capital as outlined by Nahapiet and Ghoshal [Nahapiet, J. and Ghoshal, S. (1998) Social capital, intellectual capital and the organizational advantage. Academy of Management Review, 23, 242-266.], to investigate the operation of business networks within Russia. Focusing on a generation of Russian business managers who had minimal exposure to the previous regime and who experienced western education/business practices, this study illustrates one snapshot of social capital in Russia in 2004. Results highlight how this generation of business managers operates and how they conduct their business networks. It is expected that there will be changes in Russian business networks, as formalized legal systems become stronger and the new generation of Russian managers, who have had little exposure to socialist systems and nomenklatura emerge.
