... The focus of biomimetic design is to identify relevant biological strategies [7]. Generally, the common search process of identifying relevant biological strategies for a given engineering problem can be concluded in three parts: consulting biologist, processing natural language source of knowledge and using biological strategies in biomimetic database [8], as shown in Fig. 1a. However, biomimetic design as a biological knowledgedriven design method is challenging because it requires biological and engineering knowledge [9,10]. ...

The biomimetic design provides an adequate solution to attain an excellent design. However, the prototype space for biomimetic design is relatively large, and it becomes more and more challenging to find the required biological prototypes efficiently and accurately. To improve the design efficiency and enrich the biomimetic information, this paper proposes a coupled biological strategies-enabled bidirectional encoder representation from transformers (BERT) model to assist biomimetic design, namely BioDesign. We extract the biological strategies and extract dimensional information from AskNature as a part of the database. The linguistic expression model-BERT helps to search for biological strategy. Based on the coupled biological strategies analysis, the quantitative results of biomimetic strategies are given by BioDesign. Finally, we take the erosion wear-resistant design of the control valve core as an example to demonstrate the utilization based on the proposed BioDesign. The erosion wear experiment demonstrated the feasibility and effectiveness of the proposed method.
... A lack of expertise is often associated with an imbalanced design team where either the biology or the engineering (for example) are not well represented, sometimes missing entirely. Most often, it is the biological expertise that is absent (e.g., [4,11,14]), though it remains unclear the degree to which it should be represented. With larger design teams, more methods or processes, and the need to integrate research and development across several disciplines, resourcing becomes far greater than a project existing within a single domain. ...

Biomimetics must be taught to the next generation of designers in the interest of delivering solutions for current problems. Teaching biomimetics involves teachers and students from and in various disciplines at different stages of the educational system. There is no common understanding of how and what to teach in the different phases of the educational pipeline. This manuscript describes different perspectives, expectations, needs, and challenges of users from various backgrounds. It focuses on how biomimetics is taught at the various stages of education and career: from K-12 to higher education to continuing education. By constructing the biomimetics education pipeline, we find that some industry challenges are addressed and provide opportunities to transfer the lessons to application. We also identify existing gaps in the biomimetics education pipeline that could further advance industry application if a curriculum is developed.
... To utilize knowledge from biology, engineers and designers must first be able to comprehend it, then translate it into a context that is relevant to the problem they are solving. One way to do this would be to have a biologist as part of the team [10,11]. Another way is to introduce tools and processes for practicing BID. ...

Bio-inspired design (BID) has the potential to evolve the way engineers and designers solve problems. Several tools have been developed to assist one or multiple phases of the BID process. These tools, typically studied individually and through the performance of college students, have yielded interesting results for increasing the novelty of solutions. However, not much is known about the likelihood of the tools being integrated into the design and development process of established companies. The mixed-methods study presented in this paper seeks to address this gap by providing industry engineers and designers hands-on training with the BID process and four BID tools. Understanding which tools are valued and could be adopted in an industry context is the goal. The results indicate multiple encouraging outcomes including that industry practitioners highly valued the process framework tool (BID canvas) as it allows for flexibility in tool use, as well as valued learning with a suite of BID tools rather than a single one to accommodate different workflows and ways of thinking.
... In addition, the assumption that biological structures are shaped by evolution to a "high-performance" state appears to be mostly accepted, and is only occasionally discussed (Fish and Beneski 2014). Moreover, it also appears that BID data bases may be attractive for making BID-related work less dependent on biologists and/or biological expertise (Graeff et al. 2019(Graeff et al. , 2020. ...

Bio-inspired design (BID) means the concept of transferring functional principles from biology to technology. The core idea driving BID-related work is that evolution has shaped functional attributes, which are termed “adaptations” in biology, to a high functional performance by relentless selective pressure. For current methods and tools, such as data bases, it is implicitly supposed that the considered biological models are adaptations and their functions already clarified. Often, however, the identification of adaptations and their functional features is a difficult task which is not yet accomplished for numerous biological structures, as happens to be the case also for various organismic features from which successful BID developments were derived. This appears to question the relevance of the much stressed importance of evolution for BID. While it is obviously possible to derive an attractive technical principle from an observed biological effect without knowing its original functionality, this kind of BID (“analog BID”) has no further ties to biology. In contrast, a BID based on an adaptation and its function (“homolog BID”) is deeply embedded in biology. It is suggested that a serious and honest clarification of the functional background of a biological structure is an essential first step in devising a BID project, to recognize possible problems and pitfalls as well as to evaluate the need for further biological analysis.
... The transferability of an identified biological strategy into technology is complex without a good understanding of the phenomena at stake in the biological element. Tools to facilitate interdisciplinarity during bio-inspired design are increasingly numerous, but they face limitations as they are frequently designed for and by engineers rather than biologists [17] and often consider a specific objective rather than the full process. The steps of identification and understanding relevant biological models, and then of transferring a biological model to a technological concept, would thus deserve more advanced interdisciplinarity during the design process. ...

Building envelopes can manage light, heat gains or losses, and ventilation and, as such, play a key role in the overall building performance. Research has been focusing on increasing their efficiency by proposing dynamic and adaptive systems, meaning that they evolve to best meet the internal and external varying conditions. Living organisms are relevant examples of adaptability as they have evolved, facing extreme conditions while maintaining stable internal conditions for survival. From a framework based on the inspiration of living envelopes such as animal constructions or biological skins, the concept of an adaptive envelope inspired by the Morpho butterfly was proposed. The system can manage heat, air, and light transfers going through the building and includes adaptive elements with absorption coefficients varying with temperature. This paper presents the developed framework that led to the final concept as well as the concept implementation and assessment. A prototype for heat and light management was built and integrated into a test bench. Measurements were performed to provide a first assessment of the system. In parallel, geometrical parametric models were created to compare multiple configurations in regards to indicators such as air, light, or heat transfers. One of the models provided light projections on the system that were compared with measurements and validated as suitable inputs in grey-box models for the system characterization.
... However, the accessibility of these tools can ironically lead to the perpetuation of popular model species. Such databases do not represent the actual diversity of potential solutions in nature and are by no means an effective replacement for biologists who have expert knowledge on underappreciated systems or strategies (Graeff et al., 2019;Willocx et al., 2020). Therefore, the involvement of biologists continues to be crucial for diverse biological insights in bioinspired and biomimetic designs. ...

Bioinspiration and biomimetics is a rapidly growing field where insights from biology are used to solve current design challenges. Nature provides an abundance of inspiration to draw upon, yet biological information is under-exploited due to a concerning lack of engagement from biologists. To assess the extent of this problem, we surveyed the current state of the field using the Web of Science database and found that only 41% of publications on bioinspired or biomimetic research included an author affiliated with a biology-related department or organisation. In addition, most publications focus exclusively on a limited range of popular model species. Considering these findings, we highlight key reasons why greater engagement from biologists will enable new and significant insights from natural selection and the diversity of life. Likewise, biologists are missing unique opportunities to study biological phenomena from the perspective of other disciplines, particularly engineering. We discuss the importance of striving toward a bioinformed approach, as current limitations in the field can only be overcome with a greater understanding of the ecological and evolutionary contexts behind each bioinspired/biomimetic solution.
... If the potential of biomimetics has been proven over the past decades [4,5], it struggles to become an innovation strategy of reference. Where the need to further integrate biologists is underlined in the literature [6,7], the methodological framework (processes and tools), hasn't been originally designed to include these unusual profiles. Specifically, scientific literature underlines interdisciplinary communication as one of biomimetics' main challenges [8][9][10][11][12]. ...

Full text access : https://www.novatechsetproofs.com/authors/ASME/MD-20-1753.pdf Implementation of biomimetics in practical innovation strategies still faces various impediments. Multidisciplinary communication is one of the most recognized one. Enabling teammates having various cognitive and conceptual frameworks to properly exchange information is a key lever for optimization. In a previous study, we performed a comparative analysis of biologists' and engineers' cognitive and conceptual frameworks in order to support the establishment of a shared framework of reference within biomimetic teams. This theoretical work led us to consider various guidelines, embodied in a tool, LINKAGE, guiding the team along the biomimetic process, and more specifically during analysis and abstraction steps. This article presents a first version of this free access computerized tool, LINKAGE 1.2 (https://linkage-lcpi.com). After the description and positioning of LINKAGE, comparing to other existing tools, a testing phase involving 19 professionals divided into 5 interdisciplinary teams is presented. The results of this evaluation lead to the validation of some of the tool's objectives while underlining some lines of improvements. Various perspectives on the tool's development are also presented.
... Biomimetic technologies are currently being adapted into the aerospace industry by evaluating its potential for innovative solutions (Bar-Cohen 2006, 2011Bechert et al. 1997). Methodological frameworks for biomimetic technological applications are being devised for realizing these solutions (Fayemi et al. 2014;Graeff et al. 2019). The industrial applications of biomimetics are being accosted through a two way approach (i.e.)., applying the knowledge of biology into engineering fields and the other approach is to solve engineering problems by means of biomimetics (Miyauchi and Shimomura 2019). ...

Bio-inspired designs have been serving as a great inspiration for Aerodynamists for the past several decades. The biological features of each species have evolved through generations that play a substantial role in their ultimate survival. Manmade technologies have significantly benefited from these evolutionary attributes by mimicking such optimal features through artificial means of engineering. Biologically mimicking a particular feature of a natural species for scientific applications has introduced an interdisciplinary field of study that is popularly termed as “Biomimetics”. Biomimetic solutions have gained greater scope because of their unique potential to address the existing design challenges. The present review article approaches the state-of-the-art biomimetic techniques in a qualitative as well as quantitative perspective by mainly focusing on the potential aerodynamic applications. Through a quantitative approach, emerging researchers can have a firm basis from a pool of existing techniques. Drag reduction, lift enhancement, and flow separation control are the major design optimization challenges existing in the field of aerodynamics. The Biomimetic techniques discussed herein are evaluated on such qualities through consecutively organized sections which are the key instruments for non-flapping applications. A critical review on the well-liked biomimetic techniques for flow control is addressed with their potential applications in relevance to the aerospace industry. Few patented techniques from allied fields like hydrodynamics are also discussed because of their conceptual effectiveness in aerodynamic applications. Furthermore, the flow control effectiveness of Humpback Whale (HW) inspired biomimetic leading edge tubercles is numerically investigated with straight and sweptback wing configurations. The results clearly indicate the potentials of biomimetic techniques to transform the future designs of aerodynamic surfaces.
... A recognized shortcoming of BID is that the majority of methods have been developed from a purely technical perspective and without integrating knowledge and approaches from biologists into the development process. In this respect, a considerable number of recent contributions target the role of expertise of designers, technicians and biologists in the successful application of BID (Graeff et al., 2019;Hashemi Farzaneh, 2020;Letard et al., 2020). However, this limitation is partially alleviated in that BID is oriented to acquire biology knowledge without integrating biological elements into designs, differently from e.g., biophilic design (Sayuti and Ahmed-Kristensen, 2020). ...

The 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.
... A major drawback of consulting an expert biologist is the limit of his or her current knowledge and the possible bias to his/her own research domain (Shu et al., 2011;Graeff et al., 2020). The major issue with database approaches is the enormous effort that is required for the population of the database with biological strategies Graeff et al., 2019a). The natural language search tools result in a large quantity of potentially relevant biological documents, which makes the selection of relevant documents time-consuming (Kaiser et al., 2013;Willocx et al., 2020). ...
... This biologist performs a constant pre-evaluation of the biological strategies encountered, keeping only the most relevant strategies for consideration (Lenau et al., 2011). To be able to recall a large variety of relevant biological strategies, this biologist needs to have a wide basis of biology, which is a rare profile (Graeff et al., 2019a). Tools and methods supporting filtering and selecting biological inspiration rely on having the engineer understand the retrieved strategies and manually select the most relevant for their problem (Lenau et al., 2018). ...

Using bio-inspiration allows engineers to use the knowledge implicitly built up by natural evolution. Current tools for providing engineers with bio-inspiration yield many biological working principles. Starting from the Linnaean taxonomy, which can be seen as a design revision history, this work proposes metrics for a working principle based on the observations of that working principle in different organisms. A first metric measures the reinforcement of a working principle via the number of observations (publications/submissions to a database) made by biologists. Furthermore, biological strategies that evolve independently and use the same working principle might be more resilient and globally applicable, prompting the proposal of a metric measuring the spread in the taxonomy. Finally, bio-novelty measures the biological novelty, inversely related to the biological diversity employing the working principle. To illustrate the use of the metrics, they are applied to the working principles identified in the ‘temporary attachment’ category of AskNature.
