Course: Nature Inspired Design & Engineering
A research-driven course focused on applying principles from nature to inspire innovative product designs. Rather than simply copying biological forms, the course emphasizes understanding and abstracting functional principles from natural systems to create sustainable, practical engineering solutions.
In this project, we explored biological mechanisms for controlled release and self-sealing functions, focusing on the explosive seed dispersal system of Impatiens glandulifera. Through detailed biological analysis and abstraction, we developed a Biological Design Principle (BDP) and an Abstracted Design Principle (ADP), translating the plant’s natural mechanisms into engineering concepts for controlled-release systems. The outcome formed a conceptual foundation for future material or product development inspired by nature’s efficient structural solutions.
Methodology
The project followed a structured bio-inspired design process, beginning with biological exploration and culminating in the formulation of engineering-relevant design principles. We selected the Impatiens glandulifera seed pod due to its remarkable natural mechanism for explosive seed dispersal.
We conducted a detailed biological analysis, focusing on the pod’s structure, material behavior, and the environmental triggers behind its self-deforming motion. From this, we developed a Biological Design Principle (BDP) to describe how the plant controls release through internal tension and moisture response.
This understanding was then abstracted into an Abstracted Design Principle (ADP) by translating biological terms into functional engineering language. The ADP outlines how controlled energy storage and directional release can be achieved using elastic deformation and responsive materials—opening up possibilities for biomimetic applications in packaging, medication capsules, or self-sealing systems.
Biological Design Principle (BDP)
The BDP was derived from studying the explosive seed dispersal mechanism of Impatiens glandulifera. This plant stores elastic energy in its seed pod walls as they dry and contract. Upon reaching a certain tension threshold, the pod's structure rapidly coils inward, launching seeds in multiple directions. The energy release is sudden, efficient, and entirely passive—triggered by internal stress rather than external force. This biological strategy enables precise, controlled release using only structural tension and environmental conditions like moisture loss.
Abstracted Design Principle (ADP)
Translating this biological insight into engineering terms, we defined an ADP centered on controlled energy release through pre-stressed elastic structures. The principle involves materials or systems that gradually build internal stress under specific conditions (e.g., drying or mechanical loading) and release this energy in a controlled, self-actuating motion when a threshold is reached. Key elements of the ADP include energy storage in flexible materials, passive triggering mechanisms, and directional force release. This abstraction allows the principle to be applied across various domains, from mechanical actuators to packaging technologies.
Final Concept
The final design concept applies the ADP to envision a self-sealing, one-time-use capsule system. The capsule would consist of a flexible membrane or housing that builds tension under changing humidity or pressure. When a threshold is met, the capsule either snaps open or seals itself, depending on its intended function. This nature-inspired approach could provide sustainable alternatives for controlled-release products in fields such as agriculture, pharmaceuticals, or single-use packaging, offering passive, material-based solutions without the need for electronics or external actuation.
Personal Contributions
In this project, I contributed primarily during the initial research phase, exploring biological systems and helping identify Impatiens glandulifera as our focus organism. I supported the development of both the Biological Design Principle (BDP) and the Abstracted Design Principle (ADP) by contributing to the biological analysis and the translation of natural functions into engineering-relevant terms. My main responsibility, however, was in the graphic design and visual communication of our work. I took charge of designing the final poster, structuring and formatting the report, and ensuring that the core ideas, especially the BDP and ADP, were clearly and visually accessible.
