On the benefits and pitfalls of analogies for innovative design : Ideation performance based on analogical distance, commonness, and modality of examples
TLDR
Positive effects of far-field and less-common examples on novelty and variability in quality of solution concepts are shown and guidelines for the effective design and implementation of design-by-analogy methods are suggested, particularly a focus on far- field, less- common examples during the ideation process. Expand
The Meaning of “Near” and “Far”: The Impact of Structuring Design Databases and the Effect of Distance of Analogy on Design Output
TLDR
A cognitive engineering design study is presented that examines the effect of the distance of analogical design stimuli on design solution generation and confirms that “near” and “far” are relative terms, and depend on the characteristics of the potential stimuli. Expand
Do the best design ideas (really) come from conceptually distant sources of inspiration
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… Expand
IdeaHound: Improving Large-scale Collaborative Ideation with Crowd-Powered Real-time Semantic Modeling
TLDR
This paper introduces IdeaHound, an ideation system that seamlessly integrates the task of defining semantic relationships among ideas into the primary task of idea generation, and creates a more accurate semantic model than an existing crowdsourced approach (performed by external crowds). Expand
SOLVENT: A Mixed Initiative System for Finding Analogies between Research Papers
TLDR
SOLVENT is introduced, a mixed-initiative system where humans annotate aspects of research papers that denote their background, purpose, mechanism, and findings, and a computational model constructs a semantic representation from these annotations that can be used to find analogies among the research papers. Expand
Improving Crowd Innovation with Expert Facilitation
TLDR
A crowd ideation system where experts monitor incoming ideas through a dashboard and offer high-level “inspirations” to guide ideation shows that expert facilitation can significantly improve crowd innovation, but inexperienced facilitators may need scaffolding to be successful. Expand
Providing Timely Examples Improves the Quantity and Quality of Generated Ideas
TLDR
Insight from this study can inform the design of collective ideation support systems that help people generate many high quality ideas, and emphasize the importance of the timing of example delivery. Expand
The Impact of Analogies on Creative Concept Generation: Lessons From an In Vivo Study in Engineering Design
TLDR
Surprisingly, it was found that concepts were more similar to their preceding concepts after far analogy use compared to baseline situations (i.e., without far analogyUse), and far analogies increased the team's concept generation rate comparedto baseline conditions. Expand
The importance of iteration in creative conceptual combination
TLDR
This work traces conceptual genealogies of many hundreds of concepts proposed for a dozen different problems on a large-scale Web-based innovation platform, and model the effects of combination distance on creative outcomes of concepts to lend clarity to theories of creative conceptual combination and highlight the importance of iteration for generating creative concepts. Expand
THE MEANING OF "NEAR" AND "FAR": THE IMPACT OF STRUCTURING DESIGN DATABASES AND THE EFFECT OF DISTANCE OF ANALOGY ON DESIGN OUTPUT
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… Expand
