How Is Geometry Used in Engineering Design
Geometry is an integral part of design from start to finish.
Just think about it. Architects use geometry to study and divide space as well as draft detailed building plans. Builders and engineers rely on geometric principles to create structures safely. Designers apply geometry (along with color and scale) to make the aesthetically pleasing spaces inside. Applying geometry in design is unavoidable.
We have plenty of examples of creative applications of geometry, from the elaborate patterns found within Islamic architecture to the complex fractals in Pollock's drip paintings to the clean lines of modern interiors. Why is geometry such an enduring foundation of our work? How can we apply it in ways that not only appeal to our senses but also to our sense of well-being?
Short answer — look to nature.
Natural geometry
Pattern can be found everywhere in nature: tree branches, snowflakes, zebra stripes, nautilus shells. We've been studying these natural patterns since ancient times, and only recently have we really been able to explain them with mathematics, physics, and chemistry. Perhaps it's this mystery and complexity that draws us to geometric patterns in the first place.
The most commonly-found natural patterns are:
- Symmetry – the near-repetition of a pattern element by reflection or rotation
- Spirals – a continuous and gradually widening (or tightening) curve around a central point
- Fractals – similar patterns recurring at progressively smaller scales
- Tessellations – patterns formed by repeating tiles on a flat surface
Flowers have a natural symmetrical structure.
Bee honeycombs are a natural tessellation of small hexagons.
This bisected look at the inside of a nautilus shell show the spiral inside – a perfect example of the Golden Ratio.
Romanesco broccoli has a distinct spiraling fractal pattern.
Geometry in Design
Bringing the outside in with biomorphic patterns
Research shows that views of nature have an impact on our psychology and physiology. Likewise, natural elements and even representations of them using Biomorphic Forms & Patterns create spaces that are "comfortable [and] captivating…"1
Connecting to nature in this way allows us to draw on geometric design patterns for inspiration. Avoiding right angles and straight lines for more organic movement within a space or using the Fibonacci series to create proportion are two examples of applied geometry in design.
From large, 3-dimensional structures that evoke honeycombs to cosmetic details that mimic vine growth, Biomorphic Forms & Patterns bring nature to life and reduce stress within our environment. And, it works at a large or small scale.
What are some easy ways to apply this biophilic design pattern?
- Pathway and hallway design
- Fabrics, carpet, and wallpaper designs based on Fibonacci series or Golden Ratio
- Arrangement of the structural system (columns shaped like trees, railings like branches)
- Furniture shape
Biomorphic patterns (such as honeycomb-like hexagons) create interesting spaces through the application of tessellations. Product shown: Let It Bee collection
Where geometric patterns and biophilia meet
Geometry also comes into play through the biophilic design pattern of Complexity & Order. Rooted in research on fractal geometries, Complexity & Order concerns our responses to fractals in nature, art and architecture.
In spaces that utilize Complexity & Order, we tend to feel less stress and more engagement. This is because they reveal rich sensory information similar to what we encounter in nature – the sweet spot between uninteresting and over-stimulating.2
How do we apply Complexity & Order to a space?
- Exposed structures or exoskeletons
- Modular systems such as carpet tiles, multi-purpose furniture or the incorporation of flexible, multi-use areas within a larger layout
- Architectural ornamentation and wall art
An obvious application of geometry in design (and Complexity & Order) can be found in Islamic art and architecture. Think: bold-colored kilim carpets, Moroccan tilework and star-covered mosques.

The goal of designing with this pattern is to create an enriching environment based on an understanding of the symmetries, fractal geometries and spatial hierarchies found in nature. The more complex a system is, the more ordered it becomes. The more ordered it is, the more at-ease we feel.
Humans instinctively gravitate to visually interesting spaces. By understanding the mathematics behind complex design and using nature as a guide, we can bring more of what's outside into our built environment.
