This paper reports insights gained from observing groups of novice designers apply biological analogies to solve design problems. We recorded the discourse of fourth-year mechanical engineering students during biomimetic design sessions. We observed that the availability of associations from superficial or functional characteristics of biological knowledge(More)
While biology is well recognized as a good source of analogies for engineering design, the steps of 1) retrieving relevant analogies and 2) applying these analogies are not trivial. Our recent work translated the functional terms of the Functional Basis into biologically meaningful keywords that can help engineers search for and retrieve relevant biological(More)
Biology has long been recognized as an excellent source of analogies and stimuli for engineering design. Previous work focused on the systematic identification of relevant biological analogies by searching for instances of functional keywords in biological information in natural language format. This past work revealed that engineering keywords couldn't(More)
This paper presents our research approach and challenges in designing natural language interaction for a mechanical computer-aided design (CAD) system. We intend to use natural language input, ideally speech, as one method for capturing design problem definition from designers. Based on the problem definition, a new type of CAD system could explore a set of(More)
Identifying relevant analogies from biology is a significant challenge in biomimetic design. Our natural-language approach addresses this challenge by developing techniques to search biological information in natural-language format, such as books or papers. This paper presents the application of natural-language processing techniques, such as(More)
This paper presents a method to automatically extract function knowledge from natural language text. Our method uses syntactic rules to extract subject-verb-object triplets from parsed text. We then leverage the Functional Basis taxonomy, WordNet, and word2vec to classify the triplets as artifact-function-energy flow knowledge. For evaluation, we compare(More)
Biomimetic design, which borrows ideas from nature to solve engineering problems, has been identified as a promising method of concept generation. However, there are still many challenges. Previous research has revealed that novice designers have difficulties in extracting the analogical strategy present in biological phenomena and mapping the strategy even(More)
Categorizing biological information can be subjective and ambiguous, which poses challenges for indexing potentially useful biological information for design. Therefore, we explored collective categorization to study the categorization task. After gathering 163 examples of biological transformation, we asked four participants to independently categorize the(More)
