2.2 Problem definition and biological solution search

Defining the problem and searching for biological solutions are crucial steps in biomimicry. These processes involve breaking down challenges, identifying root causes, and establishing clear goals. They set the foundation for finding innovative solutions inspired by nature.

The biological solution search process is systematic, involving abstraction, translation, and literature review. It requires creativity and scientific knowledge to identify promising strategies from nature that can be applied to human design challenges.

Importance of problem definition

• Clearly defining the problem is crucial in biomimicry as it sets the foundation for the entire solution search process
• A well-defined problem helps to focus the search for biological strategies and ensures that the solutions found are relevant and applicable
• Investing time in problem definition upfront can save significant time and resources later in the biomimicry process

1 of 3

• Break down the overall challenge into specific sub-problems or functions that need to be addressed
• Identify the key stakeholders involved and understand their needs and constraints
• Determine the scope and boundaries of the problem, including any limitations or non-negotiables

Identifying root causes

• Dig deeper into the underlying causes of the problem rather than just addressing symptoms
• Use techniques like the 5 Whys or Fishbone Diagram to uncover the fundamental issues
• Consider both technical and non-technical factors that may be contributing to the problem

Defining desired outcomes

• Establish clear and measurable goals for what a successful solution should achieve
• Define the specific performance criteria and metrics that will be used to evaluate potential solutions
• Consider the broader impact and implications of solving the problem, including any potential unintended consequences

Biological solution search process

• The biological solution search process is a systematic approach to finding relevant strategies from nature that can inspire innovative solutions to human challenges
• It involves abstracting the problem, translating it into biological terms, searching for relevant organisms and strategies, and extracting key principles that can be applied to the design process
• This process requires a combination of creativity, scientific knowledge, and persistence to identify the most promising biological solutions

Abstracting the problem

• Reframe the problem in more general and fundamental terms, focusing on the essential functions and constraints
• Strip away any human-centric or domain-specific language to make the problem more accessible to biological analogs
• Consider the problem at multiple scales and levels of hierarchy to identify potential solutions at different levels of organization

Translating to biological terms

• Convert the abstracted problem statement into terminology that is more compatible with biological systems and processes
• Use action words and object words that describe the key functions and components of the problem
• Identify relevant biological domains or fields that may hold promising solutions (physiology, ecology, biochemistry, etc.)

Searching biological literature

• Conduct a broad search of scientific databases, journals, and other resources to find organisms and systems that solve similar problems
• Use a combination of keywords, synonyms, and related terms to cast a wide net and capture a diversity of potential solutions
• Iterate and refine the search based on the initial results, following promising leads and exploring tangential areas

Identifying relevant organisms

• From the literature search results, identify specific organisms or biological systems that exhibit strategies relevant to the problem
• Look for organisms that have evolved under similar constraints or selective pressures as the problem context
• Consider both iconic examples (gecko feet for adhesion) as well as lesser-known or extreme cases that may offer novel insights

Extracting key strategies

• For each relevant organism or system identified, analyze and extract the key functional principles and mechanisms at play
• Look for common patterns or themes across multiple biological examples that may point to fundamental solution principles
• Abstract the biological strategies to a level that can be more readily applied to the human design context

Techniques for problem abstraction

• Problem abstraction is the process of reframing a specific problem in more general and fundamental terms to facilitate the search for biological analogs
• It involves breaking down the problem into its essential functions and constraints, and stripping away any human-centric or domain-specific language
• Effective problem abstraction requires a balance of simplification and specificity to ensure that the abstracted problem statement is both accessible to biological systems and still relevant to the original challenge

Functional decomposition

• Break down the problem into its core functions or sub-functions that need to be performed
• Identify the key inputs, outputs, and transformations involved in each function
• Consider the problem at multiple levels of hierarchy, from the overall system level down to individual components or processes

Boundary conditions

• Define the operating environment and constraints within which the solution must function
• Identify any physical, chemical, temporal, or spatial limitations that the solution must accommodate
• Consider the available resources, energy requirements, and other factors that may shape the solution space

Solution-neutral problem statement

• Reframe the problem statement in a way that does not presume any particular solution or approach
• Focus on the desired outcomes and performance criteria rather than specifying a particular mechanism or technology
• Use language that is more compatible with biological systems and processes, such as "prevent" instead of "repel" or "manage" instead of "regulate"

Biological keyword generation

• Biological keyword generation is the process of translating the abstracted problem statement into terminology that can be used to search for relevant biological strategies
• It involves identifying key action words and object words that describe the essential functions and components of the problem
• Effective keyword generation requires a balance of specificity and breadth to ensure that the search captures a wide range of potential solutions while still remaining relevant to the problem at hand

Action words vs object words

• Action words describe the key functions or processes involved in the problem (filter, pump, sense, etc.)
• Object words describe the key components or entities involved in the problem (water, nutrients, predators, etc.)
• Use a combination of action and object words to capture the full scope of the problem and search for relevant biological analogs

Thesaurus use for variations

• Use a thesaurus to generate synonyms and related terms for each keyword to expand the search space
• Consider using both technical and non-technical language to capture a broader range of potential sources
• Iterate and refine the keyword list based on the initial search results and any new insights or directions that emerge

Biological term mapping

• Map the abstracted problem keywords to specific biological terms and concepts that may be more familiar to biologists and other domain experts
• Use resources like the "Life's Principles" or "Biomimicry Taxonomy" to identify relevant biological domains and terminology
• Consult with biologists or other subject matter experts to validate the keyword mapping and identify any additional terms or concepts to include

Biological literature resources

• Biological literature resources are the various databases, journals, and other sources that can be used to search for relevant biological strategies and organisms
• These resources span a wide range of biological disciplines and scales, from molecular biology to ecology and evolution
• Effective biological solution search requires a combination of targeted searching in specialized databases and broader exploration in more general sources to capture a diversity of potential solutions

Scientific databases

• Use specialized scientific databases like Web of Science, Scopus, or PubMed to search for peer-reviewed articles and studies
• Focus on databases that cover relevant biological domains (botany, zoology, microbiology, etc.) and interdisciplinary fields (biomaterials, biomechanics, etc.)
• Use advanced search techniques like Boolean operators, phrase searching, and keyword truncation to refine the search results

Biomimicry taxonomy

• Use the Biomimicry Taxonomy as a structured framework for exploring biological strategies and functions
• The taxonomy organizes biological information into functional categories (move, protect, maintain, etc.) and sub-categories that can guide the search process
• Use the taxonomy to identify relevant categories and keywords, and to explore related strategies and organisms within each category

Asknature.org

• Use AskNature.org as a curated database of biological strategies and case studies specifically designed for biomimicry applications
• Search by function, strategy, or organism to find relevant examples and abstractions
• Use the "Collections" feature to explore pre-compiled sets of strategies around common design challenges or biological functions

Evaluating biological strategies

• Evaluating biological strategies involves assessing the relevance, feasibility, and potential impact of each strategy relative to the original problem context
• It requires a critical analysis of the key principles and mechanisms underlying each strategy, and a consideration of how well they map to the specific constraints and requirements of the problem
• Effective evaluation requires a balance of open-mindedness and rigor to identify the most promising strategies while also remaining grounded in the realities of the design context

Relevance to problem

• Assess how well each biological strategy aligns with the specific functions and constraints of the original problem
• Consider the similarities and differences between the biological context and the human application in terms of scale, materials, energy requirements, etc.
• Prioritize strategies that address the core functions and constraints of the problem over those that are only tangentially related

Level of abstraction

• Evaluate the level of abstraction of each biological strategy and how well it maps to the human design context
• Strategies that are too specific to a particular organism or context may be difficult to translate or adapt to the problem at hand
• Strategies that are too abstract or general may lack the specificity needed to generate actionable design principles or solutions

Feasibility of emulation

• Consider the feasibility of emulating or adapting each biological strategy within the constraints of the human application
• Assess the availability of materials, manufacturing processes, and other resources needed to implement the strategy
• Identify any technical, economic, or regulatory barriers that may impact the viability of the strategy in the short or long term

Organizing biological findings

• Organizing biological findings involves synthesizing and structuring the information gathered from the literature search and evaluation process
• It requires a systematic approach to categorizing strategies, mapping functional analogies, and visualizing the solution space
• Effective organization helps to identify patterns and relationships among strategies, and facilitates the translation of biological principles into actionable design concepts

Strategy categorization

• Group biological strategies into categories based on common functions, mechanisms, or principles
• Use a hierarchical or nested structure to organize strategies from broad functional categories down to specific implementation details
• Consider using existing frameworks like the Biomimicry Taxonomy or Life's Principles to guide the categorization process

Functional analogy mapping

• Map the biological strategies to the specific functions and sub-functions of the original problem
• Identify the key functional analogies between the biological and human contexts, and the specific mechanisms or principles that enable those functions
• Use visual tools like mind maps, concept maps, or functional diagrams to represent the relationships and dependencies among strategies and functions

Creating a solution space

• Synthesize the categorized strategies and functional analogies into a coherent solution space that represents the range of potential biomimetic solutions
• Use visual tools like morphological charts, strategy matrices, or design landscapes to represent the key dimensions and parameters of the solution space
• Identify any gaps or opportunities in the solution space that may require further exploration or ideation

Challenges in biological search

• Challenges in biological search can arise due to the inherent complexity and diversity of biological systems, as well as the differences in language and terminology between biology and engineering
• These challenges can impact the efficiency and effectiveness of the search process, and may require additional time and effort to overcome
• Anticipating and addressing these challenges upfront can help to streamline the search process and improve the quality and relevance of the resulting strategies and solutions

Navigating jargon and terminology

• Biological literature often uses specialized jargon and terminology that may be unfamiliar or confusing to non-experts
• This can make it difficult to identify relevant keywords and search terms, and to interpret the key findings and principles from the literature
• Strategies for overcoming this challenge include consulting with biologists or other subject matter experts, using glossaries and ontologies to map terms across domains, and iteratively refining the search based on the results and feedback

Dealing with incomplete information

• Biological studies may not always provide complete or detailed information about the mechanisms or principles underlying a particular strategy or function
• This can make it difficult to fully understand or abstract the key principles, or to assess the feasibility of emulating the strategy in a human application
• Strategies for overcoming this challenge include cross-referencing multiple sources and studies, making informed inferences based on related examples or principles, and conducting targeted experiments or modeling to fill in the gaps

Analogical transfer difficulties

• Transferring knowledge and principles from the biological domain to the human application can be challenging due to differences in scale, materials, manufacturing processes, and other factors
• This can require significant creativity and problem-solving to identify functional analogies and adapt the biological strategies to the constraints of the human context
• Strategies for overcoming this challenge include using a systematic process of abstraction and translation, leveraging interdisciplinary collaboration and expertise, and using rapid prototyping and experimentation to test and refine the biomimetic concepts
