Proof of principle
Prove that the core mechanism, physics or technical approach can work before investing in a complete product.
Prototype developmentTurn an idea into something you can test.
Twocan designs, builds and develops functional prototypes for products and technical systems. We can start from a sketch, CAD model, calculation, proof of principle or existing prototype — then engineer the next physical version around what you actually need to learn or demonstrate.
Working proofA prototype should answer a question, demonstrate a function or unlock the next decision — not simply look finished.

Start with the problem
What kind of prototype do you need?
The right prototype depends on the decision it needs to support. Higher fidelity is not automatically better — the aim is to spend enough to create useful evidence, then iterate.
Functional prototype
Integrate the important systems so performance, usability, fit or behaviour can be tested in something representative.
Investor or exhibition demonstrator
Create a robust physical system that communicates the idea clearly in meetings, demonstrations or events.
Next-version prototype
Improve an existing build that is too heavy, awkward, fragile, difficult to assemble or not yet representative enough.
Relevant work · GiroStor
From spreadsheet to working demonstrator.
GiroStor had an early flywheel energy concept supported by calculations and presentation material. Twocan developed the technical model and built a working benchtop demonstrator that combined rotating hardware, electronics, controls and a touchscreen showing live output.
The physical build gave the project a much more tangible way to explain the concept in investor conversations while exposing the real engineering considerations involved in making it work safely.

How we work
Prototype to learn, not prototype to impress.
We define the job of the prototype first. That keeps the build focused, avoids premature detail and makes each iteration useful.
Define the proof
What must this prototype demonstrate, measure, communicate or de-risk?
Choose fidelity
Select the minimum representative level of geometry, materials, controls and finish needed for that job.
Engineer
Develop CAD, interfaces, calculations, safety considerations and the build approach.
Build & integrate
Source parts, manufacture components, assemble and integrate mechanical and electronic systems.
Test & iterate
Use the prototype, capture failures and learning, then update the design for the next development stage.
Not every project needs every stage. We scope around the next useful decision and the evidence needed to make it.
Why Twocan
Why Twocan for prototype development?
Our prototype work stays connected to engineering intent. We are interested in whether the build answers the right question and moves the project forward.
◎
Hands-on delivery
We are comfortable carrying work from CAD into sourcing, assembly, troubleshooting and test.
◇
Build what matters
Prototype fidelity is chosen around the evidence you need rather than an arbitrary idea of “finished”.
△
Improve existing work
We do not need to start from a blank sheet. Existing prototypes can often be selectively upgraded.

Think beyond the demo
Where appropriate, prototype decisions are made with later manufacture, cost and integration in mind.

Common questions
Useful answers before the first call.
If your project does not fit neatly into one of these questions, that is normal. Early engineering work is often about clarifying the problem before deciding what work package makes sense.
Can you build a prototype from just an idea?
Yes, but we normally begin by turning the idea into clearer requirements and deciding what the first prototype actually needs to prove.
Do you only make appearance models?
No. Twocan focuses on functional engineering prototypes and demonstrators. Appearance can matter, particularly for investor or exhibition use, but the engineering purpose comes first.
Can you improve a prototype we already have?
Yes. Existing prototypes are often the fastest route to useful progress because they show what already works and where the real problems are.
Can a prototype include electronics or controls?
Yes. We can integrate mechanical hardware with electronics, controls and user-interface elements where the project requires it.
What happens after the prototype works?
We can support the next design iteration, DFM, technical drawings, supplier engagement and the engineering needed to move towards production.
Your next sensible step
Start with what you have.
Send a sketch, photo, CAD model, prototype or a short explanation of the problem. We can talk through where the project is now, what the next useful milestone could be and whether Twocan is the right fit.
