Our manifesto

Machines should
feel human.

Not because they need faces, voices, or personalities — but because they are made by people, for people, to solve real problems.

We like mechanisms you can understand. Objects you can touch. Systems that reveal how they work instead of hiding behind complexity.

We sketch, calculate, prototype, break, rebuild, and repeat.

Mechanisms

Good mechanisms.
Designed with intention.

Systems that reveal how they work. Turn a gear. Follow a force. See what moves next.

Study 001 / From rotation to translation. Drag a gear or drag sideways. Arrow keys rotate; space pauses.
Physical objects

Ideas you can hold
in your hands.

Connected parts. Shared pivots. One input, many possibilities.

Study 002 / Connected by design. Drag a gear or drag sideways. Arrow keys rotate; space pauses.
Movement

Movement with purpose.
Every detail matters.

A crank, two pistons. Turning a little rotation into something useful.

Study 003 / Rotation meets translation. Drag a gear or drag sideways. Arrow keys rotate; space pauses.
Three humans. One approach.

We make.We learn.

Start with a real problem

Sketch it.
Ask better questions.

Understand the need, draw the possibilities, find what matters.

HUMAN INDUSTRIES® / FIELD NOTE 01
01 / 04

Ask better questions.

A mechanism begins with a question. Before a dimension, a material, or a motor, we want to understand the human problem in front of us.

FROM THE WORKSHOPSCROLL TO EXPLORE ↓
01

Start with the person.

What are they trying to do? What feels awkward, wasteful, or unnecessarily difficult? Watch the task happen. A small hesitation can tell you more than a long list of requested features.

We write the problem in plain language. Lift this load. Guide this movement. Make this adjustment easier. If the problem is still vague, adding more parts will not make it clearer.

02

Draw the movement.

A sketch lets us think with our hands. We mark the fixed points, the moving points, and the direction of a force. We draw several possibilities before falling in love with one.

At this stage, an arrow can be more useful than a polished render. The question is whether the idea makes sense, whether someone can understand it, and whether it deserves a first experiment.

03

Give every part a reason.

What does this joint allow? What does this constraint prevent? Can the same job be done with fewer pieces? Simple is something we work towards by understanding the difficult bits.

We look for arrangements that explain themselves. You should be able to follow the input, see where the motion goes, and understand why the output behaves the way it does.

04

Leave something to test.

A useful sketch carries an unanswered question into the workshop. It might be a travel distance, an awkward reach, or a connection we are unsure about.

We finish with a small next step: a cardboard model, a rough linkage, a single joint. Something we can hold, move, and learn from. Then we draw again.

Forces & tolerances

Calculate it.
Make the details count.

Work through movement, friction, materials, and joints.

HUMAN INDUSTRIES® / FIELD NOTE 02
02 / 04

Make the details count.

The details decide whether an idea moves smoothly, binds halfway through, or wears out after a week. We use calculation to make those details visible.

FROM THE WORKSHOPSCROLL TO EXPLORE ↓
01

Follow the force.

Start at the input and trace the load through every contact, shaft, fastener, and support. A diagram of the force path makes hidden assumptions easier to find.

We consider the full movement, including the positions where a linkage loses leverage. A mechanism that behaves well at one angle can ask much more of its parts somewhere else.

02

Make room for reality.

A nominal dimension is only the beginning. Fits, tolerances, alignment, and assembly order decide whether the finished parts will actually work together.

We ask where clearance helps, where backlash matters, and where compliance might be useful. We choose tolerances with the manufacturing process and the actual job in mind.

03

Choose with intention.

Materials bring stiffness, wear, weight, friction, and a way of being made. We weigh those properties against what the mechanism needs to do and how it will be maintained.

The most elaborate solution is rarely the most useful one. A familiar bearing, a replaceable bushing, or an accessible fastener can make a meaningful difference over the life of an object.

04

Write down the assumptions.

A calculation is only as useful as the conditions behind it. We record the loads, dimensions, boundary conditions, and uncertainties so we know what the result actually tells us.

Then we test the parts we are least certain about. Measurement feeds the next calculation. The model improves with the mechanism.

No unnecessary complexity

Build. Break. Learn.

Prototype it.
Put it to the test.

Make something real, see where it fails, learn from the errors.

HUMAN INDUSTRIES® / FIELD NOTE 03
03 / 04

Put it to the test.

A prototype is a question you can touch. We build it to find out what the drawing could not tell us.

FROM THE WORKSHOPSCROLL TO EXPLORE ↓
01

Build the uncertain part first.

We choose one question and make the smallest useful experiment around it. Does the joint bind? Is the motion comfortable? Is the structure stiff enough for the task?

The first version can be rough. Cardboard, printed parts, off-the-shelf hardware, and temporary fixtures all have a place when they help us learn quickly.

02

Watch the whole cycle.

Run the mechanism slowly. Follow the contacts and clearances through their full travel. Listen for rubbing and feel where the resistance changes.

We pay attention to the awkward positions. The beginning, end, and reversal of a movement often reveal things that disappear in a smooth animation.

03

Measure what changed.

We record the setup and the observations. Travel, deflection, repeatability, friction, and wear become useful when we can compare one version with the next.

A failure is evidence. We keep the broken part, photograph the contact mark, and write down what happened before changing the design.

04

Turn the result into a decision.

Keep, change, or remove. Each experiment should leave us knowing something we did not know before, even when the answer is that our first idea was wrong.

We return to the sketch with better questions. The next prototype carries that learning forward, one deliberate change at a time.

Thoughtful refinements

Rebuild it.
Keep making it better.

Question every detail. Keep what is useful. Then repeat.

HUMAN INDUSTRIES® / FIELD NOTE 04
04 / 04

Keep making it better.

The first working version is a beginning. Iteration turns something that moves into something that works well for the person using it.

FROM THE WORKSHOPSCROLL TO EXPLORE ↓
01

Keep the useful evidence.

We compare what we intended with what actually happened. We keep the measurements, the uncomfortable observations, and the details that surprised us.

A change earns its place by addressing something real. Sometimes the next version needs a stronger part. Sometimes it needs one part fewer.

02

Refine the experience.

How does the object feel in a hand? Can it be adjusted without guessing? Is the movement predictable? Can someone see when something needs attention?

These questions belong alongside the mechanical ones. Clear behaviour, accessible joints, and thoughtful feedback make a machine easier to live with.

03

Design for another day.

Parts wear. Fasteners loosen. People need to assemble, inspect, clean, and repair things. We make room for those ordinary realities in the design.

A mechanism should be understandable after it leaves the workshop. We value replaceable parts, visible connections, and documentation that helps the next person.

04

Know what better means.

We return to the original problem and ask whether the change helped. More complexity needs a clear reason. Every revision should make the mechanism more useful, dependable, or understandable.

Three humans. A lot of iterations. One machine at a time. That is how we keep learning, and how the work gets better.

FAQs

A few questions.
Human answers.

Three humans designing mechanisms with intention. We sketch, calculate, prototype, break, rebuild, and repeat — one machine at a time.

Made by people, for people, to solve real problems. Clear to understand, useful to operate, and thoughtful in the details.

Movement, friction, forces, tolerances, materials, joints, and errors. All the small details that turn an idea into something real.

We begin with the problem, explore the mechanism, and build something we can test. Each iteration tells us what to keep, change, or remove.

Complexity should earn its place. We avoid unnecessary parts, decoration pretending to be function, and technology for technology’s sake.

Absolutely. We are trying to make engineering clear, useful, thoughtful, and a little bit playful. Curiosity is part of how we work.
