Biocards and Level of Abstraction

Biocards are formal descriptions of biological phenomena and their underlying functional principles. They are used in bioinspired design to document search results and to communicate the findings for use in the further design process. The present study explored the effect of abstraction level used in biocards. This was done in two workshops conducted with design students in Denmark and India. Students were given a design assignment and instructions for how to perform the BID ideation work. Half of the students were given biocards with abstract descriptions while the other half got biocards with concrete descriptions. The novelty of found solutions was evaluated by the students by rating novelty of each solution on a scale from 1 to 5. Mean values for abstract descriptions were 0,3 higher than for concrete descriptions indicating that more innovative solutions were found when students used biocards with abstract descriptions compared to concrete descriptions. The difference in mean value is significant with a confidence level better than 1%. It seems likely that more abstract descriptions in biocards helps avoiding design fixation in biomimetic design work

About integration opportunities between TRIZ and biomimetics for inventive design

AbstractThis paper presents the first results of a Ph.D. program aimed at investigating the domain interface between TRIZ and Biomimetics within the scope of inventive design. Indeed, a few authors have already proposed as a relevant direction of research the identification of integration opportunities between TRIZ and Biomimetics towards a more effective and efficient inventive design methodology. The paper presents a comparison between the tools based on functional modeling used during the process of problem solving within TRIZ and Biomimetics. This comparison intends to elicit overlaps, complementarities and incongruences of these techniques. The indications about how to improve the process of describing natural solutions in an engineering way and how to describe technical problems in order to use natural information as source of inspiration are given by analyzing few examples. The results are discussed in terms of necessary modifications in the engineering problem description in order to use a database of biological functions (i.e. the Biomimicry Taxonomy) as a source of natural knowledge in the process of inventive design

A SPECULATION ON THE POTENTIAL SUPPORT OF BIO-INSPIRED DESIGN TO BIOLOGICALISATION IN MANUFACTURING

AbstractThe paper investigates to what extent the knowledge accumulated in the field of Bio-Inspired Design might benefit the process of biologicalisation in manufacturing. According to visions making inroads in the manufacturing field, the latter will not be limited to the consideration and the analysis of biological principles as a source of inspiration for solving technical and organizational problems. In fact, the process of biologicalisation in manufacturing foresees the development of bio-integrated and bio-intelligent systems. In light of these expected developments, Bio-Inspired Design's might fail to support the whole transition to take place in the manufacturing field. Methodological limitations still to overcome represent an important barrier in this perspective too. While a transfer of knowledge from the design to the manufacturing domain seems unlikely, the authors individuate aspects that encourage cross-fertilization between Bio-Inspired Design and biologicalisation in manufacturing. These include the need to include biologists in engineering teams, the objective of sustainable development, and a shared attention to the evolution of (Design for) Additive Manufacturing

Enhancing creativity through Biological Stimuli during new products ideation

The development of new and innovative products consists in a competitive advantage, allowing companies to overcome competitors, maintain or even increase its market share. As the product development cycle is shortening, a greater effort is required at the ideation of new technologies and products. In this context, the bio-inspired design has been receiving attention as a creativity strengthening method. However, the majority of methods and tools proposed in this field present biological stimuli in the form of literature extracts, requiring a great cognitive effort from the design teams in abstracting principles to generate ideas. In this paper a systematic approach to biological stimuli development is presented, as well as its contribution during the ideation process. An experiment was conducted on the context of a product design course. As result, it was evidenced that the biological stimulators contributed to the increase of the ideas\u27 utility and variety, favoring the innovation process

Modeling inspiration for innovative NPD: lessons from biomimetics

International audienceIn biomimetic design, nature - natural phenomena, systems or organisms - is used as a source of inspiration for producing new ideas or concepts. While being widely recommended this approach lacks rigorous analysis and manageable systematization that would be needed in industrial contexts. Better modeling of this process of bioinspiration is a condition for applying bioinspiration to stimulate innovation in a controlled way. This paper presents a model for bioinspiration based on the framework of the C-K design theory. This model was elaborated considering a review of the existing literature on methods for implementing biomimetic design and an analysis of selected biomimetic product development case examples. The results reveal the main roles of biological knowledge in the design process (1) indication of a "design direction", meaning an expansion on the concepts space, (2) indication of knowledge domains where no or few knowledge is available, (3) reorganization of the knowledge base, activating knowledge bases that would not otherwise be activated. This improved understanding of the bioinspiration process outlines more sophisticated and profound conditions that have to be managed for creating value

Comparing novelty of designs from biological-inspiration with those from brainstorming

This research aims to understand the significance of biological-analogies in fostering novelty by comparing biological-analogies with other design methods for idea generation. Among other design methods, brainstorming was chosen here as benchmark. Four studies were conducted to compare: (i) the levels of abstraction at which concepts were ideated using biological inspiration (represented using biocards) with that using traditional brainstorming; and (ii) the novelty of concepts produced by using these two design methods. Concepts produced in these studies were evaluated for levels of abstraction at which they were ideated, average novelty, and proportion of high-novelty concepts. Results suggest that concepts generated using biocards were ideated at higher abstraction levels than those using brainstorming, but neither were at the highest abstraction levels. The average novelty of concepts produced using biocards was found to be greater than that using brainstorming; however, no statistically significant difference was found in the proportion of high-novelty concepts. We suspect the lack of biological knowledge and cultural difference among the subjects involved in our studies as the two reasons behind the results. The results demonstrate that the design methods substantially influence the novelty of concepts generated, while indicating the need for better training in effective use of biological-analogies

Biologically Inspired Design Concept Generation Using Generative Pre-Trained Transformers

Biological systems in nature have evolved for millions of years to adapt and survive the environment. Many features they developed can be inspirational and beneficial for solving technical problems in modern industries. This leads to a specific form of design-by-analogy called bio-inspired design (BID). Although BID as a design method has been proven beneficial, the gap between biology and engineering continuously hinders designers from effectively applying the method. Therefore, we explore the recent advance of artificial intelligence (AI) for a data-driven approach to bridge the gap. This paper proposes a generative design approach based on the generative pre-trained language model (PLM) to automatically retrieve and map biological analogy and generate BID in the form of natural language. The latest generative pre-trained transformer, namely GPT-3, is used as the base PLM. Three types of design concept generators are identified and fine-tuned from the PLM according to the looseness of the problem space representation. Machine evaluators are also fine-tuned to assess the mapping relevancy between the domains within the generated BID concepts. The approach is evaluated and then employed in a real-world project of designing light-weighted flying cars during its conceptual design phase The results show our approach can generate BID concepts with good performance.Comment: Accepted by J.

Biomimetics for passive air conditioned design for buildings in the hot arid regions

The high energy consumption for air conditioning in buildings is a serious concern due to its consequences on the earth's ecological life. In nature, animals regulate their body temperature in extreme environments without prejudice to the environmental system. Therefore, this study aims to design a passive cooling unit for buildings in the hot arid regions by emulating biological cooling strategies in nature. It adopted a biomimetic exploratory method to determine three of the efficient biological cooling strategies in nature based on the morphological attributes. These are; cooling through animals’ respiratory passages, thermal radiators and airflow cooling in termite mound. A comparative study was conducted on four case studies under each of the three cooling strategies to come up with the working principles that can be used as a guide to design a biomimetic cooling system. One of these strategies, the camel nasal respiratory cooling was simulated to design a cooling unit installed in wind towers for buildings. To validate the applicability of the camel nasal-inspired cooling design, experimental tests have been conducted in both wind tower and wind tunnel in a desert city, Seiyun in Yemen. The study main parameter was the design cooling efficiency for (i) three materials: clay, clay with jute fiber, and clay with wood wool pads, (ii) design height, and (iii) climatic environmental variables. The results showed that the best cooling efficiency among the three materials was the design of clay with jute fiber 85.2 %, followed by clay with wood wool pads 76.6 %, and clay 66.3 %. The former two designs have effectively dropped the temperature in hot arid climate up to 18.9 °C for jute design and 16.5 °C for wood wool design. This indicates that the bio-inspired design can replace the mechanical air conditioning system. Additionally, the cooling efficiency of the design increases by the increment of its height and the ambient temperature. However, it decreases with the increment of the inlet air wet-bulb temperature, air humidity, and air velocity. Thus, it can be concluded that emulating biological thermo-regulatory strategies is useful for the design of energy-efficient cooling systems. This study contributes to possible passive cooling design for buildings in the hot arid regions

A preliminary research to identify the biomimetic entities for generating novel wave energy converters

Biomimetics and creatures could contribute to novel design inspirations for wave energy converter as to other engineering branches since we have seen numerous examples in engineering applications. But how to obtain valuable biological entities or bionic design cases that could produce inspirations for novel designs may be challenging for the designers of wave energy converters (WECs). This research work carries out a preliminary research on acquiring the biological entities for designers, so to obtain the innovative bio-inspired ideas for designing novel WECs. In the proposed method, the first step is to draw out the engineering terminologies based on the functions, structures and energy extraction principles of existing WECs. Then by applying ‘WordNet’, the candidate biological terminologies can be obtained. Next, using ‘AskNature’ and through manual selection and filtering, the biological terminologies can be acquired. Lastly, to use the biological terminologies to establish the reference biological entities and the information and knowledge so for designing an innovative WEC. Using the proposed methodology, a novel WEC was conceived and verified
