Our joint successes

What we do for and together with our customers can best be presented through project examples.
With the following collection we would like to present our service portfolio in technical detail for experts.
and make it understandable enough for interested parties.

Insight into our successes

System development for our customers

Dosing Test Bench.

For a large medical technology customer, we developed, built and successfully commissioned a test station for the automatic dosing of very small quantities of liquids in the field of diagnostics. What the project has to do with a raindrop?

Infusion pump.

We were able to contribute broadly to the development of this infusion pump family: harmonious collaboration through years of personal relationships, deep knowledge in requirements management, bringing together the different worlds of device and disposables. (For reasons of confidentiality here with an example image)

High-voltage distributor.

A project with positive tension! We took on the task of further developing e-mobility in public transportation with a great deal of enthusiasm. The focus here was on functional safety, which was coupled with other stakeholder requirements. We are very pleased that we could help to make your next trip with an E-bus safe, reliable and comfortable!

“High-precision, complex systems have many stumbling blocks in development. B&W develops accordingly in a targeted and structured manner.”

Diagnostic devices must work with the highest precision in order to reliably exclude incorrect measurements and subsequent incorrect treatments. To ensure this, thousands and thousands of tests have to be carried out in laboratories when developing such devices (e.g. for determining blood glucose levels in diabetes patients).

In the development of test stations for the automatic dosing of very small quantities of liquid (as small as 1% of a raindrop!), our customers have been placing their trust in us for years. The main requirements here were to perform the tests quickly and safely and to control critical environmental conditions such as temperature and humidity.

The test station was integrated into a test station system developed by us. This allows, thanks to its LabVIEW© based features, a variable system configuration as well as centrally controlled test and sequence plans. In this way, we have simultaneously established flexible modality and yet a cross-system software solution. These thus contribute significantly to the efficiency of laboratories.

“Working with B&W has been great for all trades! And on top of that, in the team we have found true partners.”

An infusion pump works directly on people, including children. It is often in use in hectic and life-threatening situations: in speeding ambulances or in intensive care units. Extreme reliability and precision are required here. The requirements for an infusion pump are correspondingly diverse. We were responsible for the mechanics development with correspondingly many interfaces to other areas. Starting with industrial design, electronics development and usability.

The task was to achieve precision in the most compact of spaces. Thus, we have developed a device in which a good design is ‘filled’ with the latest technology down to the last cubic millimeter.

The infusion pump provides the required tightness against bursting infusion bags, for example. It continues to function reliably, even if the device falls from a height of 1 m. And thanks to the noticeably improved delivery accuracy that the device now possesses compared to the predecessor product, the risk of incorrect dosing of highly effective drugs and their fatal consequences is significantly reduced.

This has resulted in a pump that exceeds today’s standards. We are proud to have developed the innovative technology of the future already today!

System development with innovative solutions in electric mobility

“B&W quickly put themselves in our shoes and understood our challenges. That’s how we successfully moved forward in leaps and bounds.”

At the beginning of an electrified journey is a fully charged battery and the safe distribution of supply voltage and power in the on-board network. In this truly exciting customer project, the task was to develop system components that ensure reliable monitoring of the high-voltage charging voltage as well as the internal vehicle electrical system for the other consumer modules in the vehicle – the high-voltage distributor.

The high-voltage distributor, HVV for short, forms the first interface in the vehicle after the charging station and is being used for the product launch in two design variants in public transport, more precisely in the 12m solo bus and the 18m articulated bus. The plan is for over 800V on-board voltage and up to 250A charging current in a first expansion stage. The development included the trades hardware software and mechanics, focused on functional safety: The HVV offers the possibility to be operated decoupled from the vehicle cooling system due to its 100% passive cooling and thus offers greater flexibility in the vehicle design.

This is also the purpose of its placement in the vehicle: the current version of the HVV is mounted directly on the roof of the vehicle. This frees up a maximum amount of space and correspondingly a lot of comfort for the occupants. In order to harmonize function and comfort in this way, we ensured that the HVV’s housing was absolutely robust and waterproof, providing optimum protection against the given environmental influences.

To implement the safety requirements, the diagnostic functionality was also implemented autonomously on a hardware basis in parallel with the software monitoring, which enabled efficient implementation of the system design. Parallel to the development, the customer maintained the requirements management and logged the test progress.

For developers, the greatest recognition is to see the customer satisfied and their concept become a reality. In this sense, we are proud of the fact that, thanks to a hands-on mentality and a high degree of parallelized work, the first vehicles with the high-voltage distributors developed by us have already been successfully released and delivered to companies in a very short time.
