Engineering design — from concept to series production
Whether a research project, first prototype, small series, industrial or consumer product. We develop with you: from the idea through robust prototypes to manufacturing. Industrial design, engineering and prototyping. From power electronics systems through devices and fixtures for measurement and medical technology to consumer products. Since 2007.
Our areas of expertise
Research & prototype
From proof of concept to a robust functional model — fast and pragmatic. A development partner for startups and R&D.
Small series
Designed for manufacturing — even small quantities are realised economically and cleanly.
Industry & series
Systems up to the MW class. Production-ready engineering, also for high volumes.

Power electronics systems
Converters, energy storage, charging infrastructure and power quality devices — from the lab sample to the MW class. We develop enclosures, cooling, mechanics and electromechanics that safely handle high power density — and accompany you from the first design through to the production-ready, proven system.

Industrial measurement technology
Devices for harsh environments: ultrasonic measurement and analysis systems, outdoor and high-protection enclosures. Robust, service-friendly and standards-compliant — we take your measuring device from concept through robust samples to reliable series production.

Devices and prototypes for medical research
Ultrasound displays and probes, ECG adapters, patient monitors. Ergonomics, hygiene and regulatory approval considered from the start — we develop functional models and devices and accompany them to successful deployment.
Research, development & prototypes
A development partner for early phases — research projects, startups and innovation departments.
Proof of concept & feasibility
Quick clarity on whether and how it can be done.
Functional models & prototypes
From 3D printing to near-production samples.
Support all the way to success
At your side from the first idea to the proven product — one point of contact across all phases who takes your project to the finish line.
Proven in series — in use across industry
For the Active Harmonic Filters everything came from a single source: conception, development, engineering and design — through to production equipment and on-site installation. Manufactured several thousand times and in use across industries: from ships to chip production and into the automotive industry.
What sets us apart
We understand power electronics — heat, power density — and develop enclosures, cooling, mechanics and design precisely for it. The electronics are developed by your team or our partners — we bring everything together into a working device. A direct line to the engineer instead of agency overhead: one point of contact from the first sketch to series production.
Innovation & Intellectual Property
Good engineering thinks in protectable solutions from day one. Four patent applications have been filed with the German Patent and Trade Mark Office (DPMA):
EV Charging Infrastructure (2019)
Three applications in the field of grid-independent charging systems: a mobile charging station with a fuel cell energy system (DE102019201715A1),
a multi-column station with modular energy management (DE102019201712A1),and a high-power charging column
with integrated thermal management at up to 350 kW (DE102019201713A1).
Wind Turbine — Gearbox Concept (2010)
An axially compact gearbox concept for wind turbines: efficient speed conversion between rotor and generator in minimal installation space (DE102010044266A1).
In addition, registered designs are held.
How we work
Conception → Design → Construction → Simulation → Evaluation → Production Support

Holger Pilz is a graduate designer (Dipl.-Designer FH) and a trained industrial mechanic. This is how devices are created that are thoughtfully designed and at the same time fit for production and real-world use. “I develop devices where power density, robustness and usability all have to be right at the same time.”
Every project matters!
Do you have a research idea, a single device or a feasibility question? Start small — with a short project: proof of concept, feasibility check or first prototype, gladly at a fixed price. No enquiry is too small.
Frequently Asked Questions
What does concept design pilz do?
concept design pilz is an owner-run industrial design studio in Stuttgart, Germany.
We develop technical products from the first concept phase through engineering to the support of series production.
Which sectors does concept design pilz work for?
Our focus areas are power electronics, renewable energy (charging stations), medical technology,
industrial measurement technology, as well as consumer goods and interior.
Does concept design pilz design the electronics itself?
No. We design and engineer the enclosures, mechanics and system components for the devices — the electronics come from the client or a partner.
This interface of design, engineering and thermal management is exactly our strength.
Does the studio also take on small projects and startups?
Yes. Small projects and startups are welcome — no project is too small.
What services does concept design pilz offer?
Concept and industrial design, engineering (SolidWorks), CAD/3D, prototypes, small series and support for series production.
Where is concept design pilz located?
In Stuttgart, Germany (Rosenbergstr. 84, 70176 Stuttgart), operating since 2007.
