Every year on June 29, industrial designers celebrate World Industrial Design Day.
It commemorates the founding of the World Design Organization in 1957, but I've always felt that it celebrates something much bigger than a profession.
It celebrates human curiosity.
The desire to look at the ordinary objects surrounding us and ask, "How can this be better?"
A better chair.
A better pen.
A safer motorcycle.
A more comfortable toothbrush.
Every product begins with someone believing that today's solution doesn't have to be tomorrow's.
That's what industrial design has always been.
The quiet pursuit of making everyday life a little better.
But this year, World Industrial Design Day made me think about something completely different.
We spend a lot of time celebrating designers.
Dieter Rams.
Jony Ive.
Charles and Ray Eames.
Naoto Fukasawa.
Yet we rarely celebrate the tools that made their work possible.
The more I thought about it, the more I realized that industrial design hasn't evolved simply because designers became more creative.
It evolved because every generation inherited better tools than the one before it.
Every generation of industrial designers thinks with the best tools available to them.
That idea fascinates me.
If you had walked into a design studio in the early 1960s, you wouldn't have found enormous displays filled with CAD software or shelves packed with 3D printers.
You would have found pencils.
Markers.
French curves.
Drafting tables.
Sheets of tracing paper layered on top of one another, each one exploring another possibility.
Designers didn't just use sketching to communicate ideas.
Sketching was the design process.
Every line represented a decision.
Every ellipse was practiced hundreds of times.
Every perspective drawing carried the responsibility of convincing engineers, manufacturers and clients that the product deserved to exist.
There was no Undo button.
No Ctrl + Z.
No quick render to check proportions.
If you wanted to understand a product, you drew it.
If you wanted to improve it, you drew it again.
The pencil wasn't just a tool.
It was where imagination became visible for the very first time.
I often wonder what it must have felt like to work in that era.
Every beautiful radio.
Every camera.
Every household appliance.
They all began as marks on paper before becoming pieces of wood, foam and clay shaped by hand.
Products from that time reflected the limitations of those tools.
They were elegant, but they were also restrained.
Straight lines.
Gentle radii.
Clean geometry.
Looking back today, it's easy to think designers simply preferred that aesthetic.
But I don't think that's the whole story.
Their tools shaped the language they could speak.
Every additional curve made drawings more difficult.
Every complex surface made prototyping slower.
Every manufacturing decision carried greater uncertainty.
Design has never been independent of its tools.
The tools quietly influence what designers believe is possible.
Ironically, this was something that bothered me when I was in design school.
I was never the strongest sketcher in my class.
I admired classmates who could fill pages with beautiful marker renderings that looked ready for a design magazine.
Mine were rarely like that.
Even today, I sketch.
But I know it isn't where I feel most comfortable.
For a long time, I thought that meant I was missing something essential as an industrial designer.
Now I see it differently.
Sketching is no longer the destination.
It's one of many languages industrial designers speak.
Sometimes the fastest way to explore an idea is with a pencil.
Sometimes it's opening CAD.
Sometimes it's printing a rough prototype before lunch.
Sometimes it's holding a physical object in your hand and realizing that the idea wasn't as good as it looked on screen.
The profession didn't abandon sketching.
It simply learned new ways of thinking.
Looking back, that's what industrial design has always done.
Every decade introduced another tool that quietly expanded the designer's imagination.
The story of industrial design isn't really the story of products.
It's the story of the tools that allowed those products to exist.
The first major shift arrived with computers.
Today it's difficult to imagine designing products without CAD, but the earliest computer-aided design systems weren't trying to replace creativity.
They were trying to replace drafting.
Engineers could create more accurate drawings.
Dimensions became easier to modify.
Manufacturing became more reliable.
But something was still missing.
Computers understood straight lines remarkably well.
Nature, unfortunately, is rarely made from straight lines.
Pick up a pebble.
Look at a bird's wing.
Run your hand across the fuel tank of a motorcycle.
Nothing exists as perfect cubes and cylinders.
The world is made of flowing surfaces.
And for a long time, computers struggled to describe those surfaces.
Designers could sculpt beautiful forms from clay, but translating those forms into mathematics was another challenge entirely.
That's when something extraordinary happened.
Mathematicians, engineers and automotive researchers weren't trying to make products prettier.
They were trying to solve a mathematical problem.
How do you describe an infinitely smooth surface using numbers?
The answer eventually became something with one of the least inspiring names in industrial design.
Non-Uniform Rational B-Splines.
Or simply, NURBS.
If you asked most industrial designers today what NURBS stands for, they'd probably hesitate.
Yet almost every product they've designed has been touched by it.
NURBS didn't invent curves.
It made curves practical.
Before NURBS, creating complex surfaces digitally often meant stitching together countless smaller patches.
Every modification risked breaking another surface.
Every refinement became slower.
Every beautiful form demanded enormous effort.
NURBS changed that.
Suddenly, a designer wasn't fighting geometry anymore.
They were sculpting with mathematics.
A single surface could flow continuously into another.
Curvature became editable.
Reflections became predictable.
Products began to feel less assembled and more sculpted.
The automotive industry embraced it almost immediately.
Cars have nowhere to hide.
Every reflection travelling across painted metal reveals the smallest imperfection.
That's why automotive studios became obsessed with something called Class-A surfacing.
Surfaces weren't judged only by dimensions anymore.
They were judged by how beautifully they reflected light.
Designers stopped asking, "Is this curve correct?"
They started asking, "Does this curve feel right?"
That subtle change transformed industrial design.
By the late 1990s and early 2000s, products around us began changing shape.
Computers became softer.
Mobile phones became friendlier.
Kitchen appliances felt more approachable.
Furniture flowed naturally instead of relying on simple geometric forms.
We often describe this as a change in aesthetic taste.
I think it was something deeper.
The software had expanded the visual vocabulary of industrial design.
Looking back today, it's easy to forget that there was a time when these forms simply weren't practical to design digitally.
Every generation inherits the tools of the previous one and quickly begins taking them for granted.
I certainly have.
Opening Fusion 360 and pulling a smooth surface across a set of curves feels completely normal to me.
But somewhere beneath every loft, every sweep and every fillet is decades of mathematical research that quietly reshaped an entire profession.
The greatest innovations in industrial design aren't always visible in the final product.
Sometimes they're hidden inside the tools we use every day.
Of all the tools that have shaped industrial design, there is one that continues to fascinate me more than any other.
Rendering.
Not because it creates beautiful images.
But because of the question it tries to answer.
What would this object look like if it already existed?
The first time I used KeyShot, I thought I was simply making my CAD model look realistic.
Years later, I realized something much more interesting was happening.
A renderer isn't painting reflections onto a product.
It isn't guessing where shadows should appear.
It isn't trying to fool your eyes.
It's performing a simulation.
Every rendered image begins with a simple question.
If light behaved exactly as it does in the real world...
...where would it go?
Millions, sometimes billions, of virtual rays leave a light source.
They strike aluminium.
Glass.
Plastic.
Leather.
They bounce.
Scatter.
Lose energy.
Pass through transparent materials.
Eventually, a tiny fraction of those rays reach the virtual camera.
The renderer doesn't invent reality.
It predicts it.
I find that idea endlessly beautiful.
Long before the first prototype exists, I can already understand how a satin finish softens reflections.
I can see how brushed aluminium catches light across a chamfer.
I can compare glossy and matte plastics before a mould has ever been machined.
I can place a product beneath an overcast sky, inside a studio, or on a mountain road at sunset without leaving my desk.
That's incredible when you stop and think about it.
Designers once relied almost entirely on imagination.
Today, we can simulate reality before reality exists.
Every generation of industrial design has reduced another layer of uncertainty.
A sketch asks, "What if?"
CAD asks, "Will it fit?"
NURBS asks, "Can we define this surface perfectly?"
A renderer asks, "How will light interact with it?"
A prototype asks, "How does it feel?"
Manufacturing asks, "Can we build it consistently?"
Every new tool answers another question before a customer ever touches the product.
Manufacturing evolved alongside these digital tools.
CNC machining gave us extraordinary precision.
Complex geometries that once took master craftsmen days to carve could now be machined repeatedly with microscopic accuracy.
Injection mould tooling became more sophisticated.
Development cycles became shorter.
Then came one of my favourite inventions.
The 3D printer.
As someone who spends a lot of time prototyping, I don't think I'll ever lose the excitement of watching an idea slowly appear layer by layer.
Something that existed only as polygons on a screen suddenly becomes an object you can hold.
You notice things the computer never could.
The grip isn't comfortable.
The button sits too high.
The corner feels sharper than it looked.
The proportions somehow feel... wrong.
A prototype has an incredible way of exposing assumptions.
That's why I don't think industrial design has become more digital.
It's become more iterative.
We sketch.
We model.
We render.
We print.
We test.
We repeat.
Every iteration removes another layer of uncertainty.
Looking back over the last sixty years, I don't think the goal of industrial design has changed at all.
We've simply become better at answering questions before committing to the final product.
The history of industrial design isn't just the history of making things.
It's the history of becoming increasingly certain that we're making the right thing.
Today, industrial design stands at another turning point.
Artificial intelligence is beginning to generate concepts.
CAD software is becoming smarter.
Simulations that once took hours now finish in minutes.
We can optimize structures automatically.
We can predict airflow.
We can estimate stresses before a part has ever been manufactured.
Some people worry that these tools will replace designers.
I don't think they will.
Every generation has feared the arrival of a new tool.
Every generation eventually realizes that the tool simply changes the way we create.
The pencil didn't replace creativity.
CAD didn't replace creativity.
NURBS didn't replace creativity.
Renderers didn't replace creativity.
AI won't replace creativity either.
It will simply become another language industrial designers learn to speak.
That's something I find reassuring.
Throughout the history of industrial design, the profession has never been defined by a particular tool.
It's been defined by curiosity.
Every new technology has simply given that curiosity a better way to express itself.
We don't design because we have CAD.
We don't design because we have AI.
We design because we believe tomorrow's product can be better than today's.
Looking back over the past sixty years, I realize that the profession has never really changed its purpose.
We've always been trying to understand people.
We've always been trying to solve problems.
We've always been trying to make everyday objects feel just a little more intuitive, more beautiful and more useful.
What has changed are the questions we're able to answer before the product reaches someone's hands.
A sketch lets us imagine.
CAD lets us define.
NURBS lets us sculpt.
Rendering lets us see.
Prototyping lets us feel.
Manufacturing lets us build.
Every new tool removes another layer of uncertainty between an idea and reality.
Industrial design is, and perhaps always has been, the pursuit of turning imagination into reality with as little uncertainty as possible.
That's probably why I find myself endlessly fascinated by these tools.
Not because they're complicated.
Not because they're impressive.
But because each one represents decades of people asking impossible questions.
How do you describe a perfect curve?
How do you simulate light?
How do you machine something to micron-level precision?
How do you transform an idea into an object without losing what made it special in the first place?
Those questions weren't answered by designers alone.
They were answered by mathematicians.
Physicists.
Engineers.
Computer scientists.
Toolmakers.
Thousands of people whose names most of us will never know.
Every beautifully designed product is also a tribute to the people who built the tools that made it possible.
Maybe that's what World Industrial Design Day means to me.
It's not just a celebration of iconic products or legendary designers.
It's a reminder that industrial design has always been a collaborative story.
A story where creativity and engineering grow together.
A story where mathematics quietly shapes beauty.
A story where software changes the forms we imagine.
A story where every generation inherits better tools and leaves behind even better ones.
Sixty years from now, someone will probably look back at our workflows the same way we look back at drafting tables today.
They'll smile at our excitement over ray tracing, generative design and AI-assisted CAD.
They'll wonder how we ever designed without whatever extraordinary tools exist in their time.
And that's exactly how progress should feel.
Every generation of industrial designers inherits the best tools the world has to offer.
Their responsibility isn't simply to use them.
It's to imagine something the previous generation couldn't.
