Biologically Inspired Design (BID), or Biomimicry, is a problem-solving methodology that applies analogies from nature to solve engineering challenges. For example, Speedo engineers designed swimsuits based on shark skin. Finding relevant biological solutions for real-world problems poses significant challenges, both due to the limited biological k...

Analogies have been central to creative problem-solving throughout the history of science and technology. As the number of scientific papers continues to increase exponentially, there is a growing opportunity for finding diverse solutions to existing problems. However, realizing this potential requires the development of a means for searching throu...

Web-scale repositories of products, patents and scientific papers offer an opportunity for creating automated systems that scour millions of ideas and assist users in discovering inspirations and solutions. Yet the common representation of ideas is in the form of raw textual descriptions, lacking important structure that is required for supporting...

Synthesis is a foundational scholarly product that generates new conceptual wholes from independent intellectual sources. But effective synthesis products—such as literature reviews—are rare, in part due to inadequate support from existing tools and information systems. A detailed, situated understanding of the work practices behind synthesis is ne...

Conducting an effective literature review is an essential step in all scientific work. However, the process is difficult, particularly for interdisciplinary work. Here, we articulate a key avenue for improvement for literature review tools: supporting the appropriate unit of interaction, which we argue is a "grounded claim", a concise statement lin...

Analogy—the ability to find and apply deep structural patterns across domains—has been fundamental to human innovation in science and technology. Today there is a growing opportunity to accelerate innovation by moving analogy out of a single person’s mind and distributing it across many information processors, both human and machine. Doing so has t...

Design ideas often come from sources of inspiration (e.g., analogous designs, prior experiences). In this paper, we test the popular but unevenly supported hypothesis that conceptually distant sources of inspiration provide the best insights for creative production. Through text analysis of hundreds of design concepts across a dozen different desig...

Scientific discoveries are often driven by finding analogies in distant domains, but the growing number of papers makes it difficult to find relevant ideas in a single discipline, let alone distant analogies in other domains. To provide computational support for finding analogies across domains, we introduce SOLVENT, a mixed-initiative system where...

The availability of large idea repositories (e.g., patents) could significantly accelerate innovation and discovery by providing people inspiration from solutions to analogous problems. However, finding useful analogies in these large, messy, real-world repositories remains a persistent challenge for both humans and computers. Previous approaches i...

Finding analogical inspirations in distant domains is a powerful way of solving problems. However, as the number of inspirations that could be matched and the dimensions on which that matching could occur grow, it becomes challenging for designers to find inspirations relevant to their needs. Furthermore, designers are often interested in exploring...

Los enfoques instructivos para la adquisición de habilidades en procesos de diseño innovativo para ingenieros y diseñadores son fundamentales para desarrollar competencias de diseño. Se necesitan recursos que permitan una evaluación eficiente y válida de los resultados del diseño, sin embargo, los métodos de evaluación actuales no son adecuados par...

The availability of large idea repositories (e.g., the U.S. patent database) could significantly accelerate innovation and discovery by providing people with inspiration from solutions to analogous problems. However, finding useful analogies in these large, messy, real-world repositories remains a persistent challenge for either human or automated...

Collaborative ideation systems can help people generate more creative ideas by exposing them to ideas different from their own. However, there are competing theoretical views on whether and when such exposure is helpful. Associationist theory suggests that exposing ideators to ideas that are semantically far from their own maximizes novel combinati...

Online crowds can help infuse creativity into the design process, but traditional strategies for leveraging them, such as large-scale ideation platforms, require time and organizational effort in order to obtain results. We propose a new method for crowd-based ideation that simplifies the process by having smaller crowds join in-person ideators dur...

What differentiates successful from unsuccessful design teams? Building on new research on design innovation that emphasizes interactions between social and cognitive processes, we investigated a potential distinguishing feature: Successful design teams may harness interpersonal conflicts (a social design process) to mitigate uncertainty (a cogniti...

Prior work on creativity support tools demonstrates how a computational semantic model of a solution space can enable interventions that substantially improve the number, quality and diversity of ideas. However, automated semantic modeling often falls short when people contribute short text snippets or sketches. Innovation platforms can employ huma...

Large-scale idea generation platforms often expose ideators to previous ideas. However, research suggests people generate better ideas if they see abstracted solution paths (e.g., descriptions of solution approaches generated through human sensemaking) rather than being inundated with all prior ideas. Automated and semi-automated methods can also o...

Online crowds are a promising source of new innovations. However, crowd innovation quality does not always match its quantity. One way to improve quality is to enable experts to provide personalized feedback. However, this scales poorly, and may lead to premature convergence during creative work. To deal with these issues, we present IdeaGens, a cr...

One main challenge in large creative online communities is helping their members find inspirational ideas from a large pool of ideas. A high-level approach to address this challenge is to create a synthesis of emerging solution space that can be used to provide participants with creative and diverse inspirational ideas of others. Existing approache...

Online crowds are a promising source of new innovations. However, crowd innovation quality does not always match its quantity. In this paper, we explore how to improve crowd innovation with real-time expert guidance. One approach would for experts to provide personalized feed-back, but this scales poorly, and may lead to premature convergence durin...

People often use spatial metaphors (e.g., think “laterally,” “outside the box”) to describe exploration of the problem space during creative problem solving. In this paper, we probe the potential cognitive underpinnings of these spatial metaphors. Drawing on theories of situative cognition, semantic foraging theory, and environmental psychology, we...

This study explored the association between different types of brief disagreements and subsequent levels of expressed psychological uncertainty, a fundamental cognitive aspect of complex problem solving. We examined 11 hours (11 861 utterances) of conversations in expert science teams, sampled across the first 90 days of the Mars Exploration Rover...

Emerging online ideation platforms with thousands of example ideas provide an important resource for creative production. But how can ideators best use these examples to create new innovations? Recent work has suggested that not just the choice of examples, but also the timing of their delivery can impact creative outcomes. Building on existing cog...

Many crowd ideation systems seek to gather scores of ideas from people online. However, this often leads to many bad ideas and duplication. A dedicated facilitator who guides exploration of the solution space is a common and effective strategy for optimizing ideation in face-to-face brainstorming, but has not yet been explored in computer-supported...

Research on innovation often highlights analogies from sources outside the current problem domain as a major source of novel concepts; however, the mechanisms underlying this relationship are not well understood. We analyzed the temporal interplay between far analogy use and creative concept generation in a professional design team's brainstorming...

In crowd-collaborative innovation platforms, other contributors' ideas can serve as sources of inspiration for creative ideas, but what patterns of interactions with others' ideas are most helpful? We investigate the hypothesis that building on inspiration sources that are conceptually far from one's target domain are most helpful, a popular hypoth...

Our prior work presented a method for computationally structuring patent databases as a basis for an automated design-by-analogy tool. In order to examine the validity and sensibility of the prior work as the basis for a design tool, its output is compared in detail to expert designers’ mental models of the domain being structured, i.e., a set of 4...

This work lends insight into the meaning and impact of "near" and "far" analogies. A cognitive engineering design study is presented that examines the effect of the distance of analogical design stimuli on design solution generation, and places those findings in context of results from the literature. The work ultimately sheds new light on the impa...

Complex problem solving in naturalistic environments is fraught with uncertainty, which has significant impacts on problem-solving behavior. Thus, theories of human problem solving should include accounts of the cognitive strategies people bring to bear to deal with uncertainty during problem solving. In this article, we present evidence that analo...

This symposium responds to calls for an integration of in-vivo and in-vitro methods when studying how people tackle complex, open-ended issues in the areas of creativity, design, and innovation. Bringing together expertise from multiple perspectives and methodological backgrounds we explore fruitful ways towards integrative approaches to analyzing...

Drawing inspiration from examples by analogy can be a powerful tool for innovative design during conceptual ideation but also carries the risk of negative design outcomes (e.g., design fixation), depending on key properties of examples. Understanding these properties is critical for effectively harnessing the power of analogy. The current research...

Design-by-analogy is a powerful method for innovation, particularly during conceptual ideation, but also carries the risk of negative design outcomes (e.g., design fixation, risk aversion), depending on key properties of analogies used. This paper examines how variations in analogical distance, commonness, and representation modality influence the...
