“…An overview of the different approaches to variety calculation is offered by Verhaegen, Vandevenne, Peeters, and Duflou (2013); who propose two main refinements to the state-of-the-art. First, a level-based variety score is detailed to allow the evaluation of the idea set on each abstraction level in the genealogy tree.…”

“…Hereby information is reported that potentially is lost when using an aggregated variety metric. Furthermore, Verhaegen et al (2013) propose a refinement to the variety metric that takes into account the uniformity of the distribution of ideas. By integrating the inverse of the Herfindahl index (Herfindahl, 1950), the new proposed variety calculation demonstrates a more gradual behaviour and avoids overestimation of the actual variety of the idea set.…”

Enhancing novelty with knowledge-based support for Biologically-Inspired Design

With a two-decade consistent research interest for Systematic BiologicallyInspired Design, a number of methods and tools to support bio-ideation have been proposed. However, objective quantification of the effects these aids have on the design outcomes is rare. This contribution presents an impact analysis of the most popular knowledge-based tool, AskNature, in the form of an outcomebased study. The results consistently support a common claim used in favour of bio-inspired design, i.e. the expectation of identifying more out-of-the-box solutions. Furthermore, to further facilitate biological solution analysis and cross-domain knowledge transfer, an adaptation to AskNature's stimuli format d i.e. adding a graphical illustration of the biological solution principle d is validated to further boost novelty. C reative problem solving is a key task for companies pursuing inventions that may grow into successful innovations. One strategy for solving new problems is learning from previously solved analogous problems. In Design-by-Analogy (DbA) a solution principle behind an already solved problem is transferred to solve a new problem. For example, when looking for new ways to unfold a tent, products with similar functionality, like for instance umbrellas, can be sources of inspiration and knowledge transfer. Biologically-Inspired Design (BID) is a specific type of between domain DbA where inspiration is taken from the natural world (source domain) to solve technical problems or challenges (target domain). Three frequently used arguments for looking at nature for inspiration are (1) the proven performance of biological systems, (2) the potential for sustainable products and (3) the potential for finding out-of-the-box solutions. The first, proven performance of biological systems, logically follows from the overwhelming evidence supporting evolution, i.e. the change in inherited characteristics of biological populations over successive generations, a continuous repetition of a non-random selection mechanism (survival of the fittest) applied to traits subject to random variation.

“…Creativity, a fundamental aspect of human intelligence, is important in designing products (Cross, 2011;Gerber & Martin, 2012;Verhaegen, Vandevenne, Peeters, & Duflou, 2013) and supporting companies to capture large market share (Eisentraut & Badke-Schaub, 1995).

Design creativity: refined method for novelty assessment

Novelty is an important characteristic of a creative idea, forming a core component of creativity. Measurement of novelty is therefore essential to assess creativity. We found deficiencies in a frequently cited method of novelty assessment found in the literature. We refine this method by proposing four modifications, supported by drawing on examples of products and ideas. The refined method and the original method are evaluated by benchmarking them against the collective, intuitive assessment of product novelty by experienced designers. The overall achievement of the refined method as presented in this paper is its contribution to a better assessment of product novelty.

“…Previous studies have investigated ways of collaboration to help further elaborate ideas (e.g., Chen, Chuy, Resendes, Scardamalia, & Bereiter, 2011;Kipp, Bittner, Bretschneider, & Marco, 2014) and ways of idea elaboration that may enhance or hinder creative knowledge work (e.g., Kudrowitz & Wallace, 2013;Stark & Perfect, 2008;Verhaegen, Vandevenne, Peeters, & Duflou, 2013). For example, Kudrowitz and Wallace's (2013) study found that the systematic use of a metric integrating three attributes (i.e., novelty, usefulness, and feasibility) as an elaboration means can be helpful in identifying more innovative ideas.…”

Understanding how students perceive the role of ideas for their knowledge work in a knowledge-building environment

This study explored how students viewed the role of ideas for knowledge work and how such view was related to their inquiry activities. Data mainly came from students' online interaction logs, group discussion and inquiry, and a survey concerning the role of ideas for knowledge work. The findings suggest that knowledge building was conducive to developing among students a more informed view of ideas that sees ideas as improvable, real-world objects for collaborative and creative knowledge work, rather than merely as abstract thoughts for achieving an individual's own knowledge acquisition. Moreover, it was found that how a group views the role of ideas was associated with how they improve the quality of the ideas during their group inquiry.
