Ever-shorter development times and ever-faster product life cycles raise the challenge of development projects that are extremely agile. This could mean we start a development project even before the requirements are fully defined, then draw up the specifications together with the customer during the course of the project. Here, we can count on our experienced team of requirements engineers.
Complex requirements are documented transparently and kept up to date at all times. Linking the requirements with the corresponding tests ensures seamless inspection of the final product. We use a requirements tool to administer the software, hardware, and mechanical systems as well as the system requirements and associated tests. Interfaces ensure a fast data exchange with our customers.
Design and performance are essential characteristics of household appliances and often the decisive purchasing arguments for final customers. Advancing technology makes both aspects extremely complex in the development of new appliances. Take for instance the use of a TFT display. It opens up completely new design options and scope for user interaction.
We meet the growing challenges in the development of sophisticated, interdisciplinary systems with a flexible, integrated approach. First, we bridge the interface between hardware and mechanical systems with state-of-the-art simulation tools. Second, we apply various agile development methods and a powerful project management software to effectively manage interdisciplinary projects.
This enables us to provide highly flexible support for our customers in the development of individual function units or complex overall systems for white goods. This applies whether it is an inverter for a washing machine or a user interface system comprising many design and/or function variants.
Our platform-based approach is the answer to the market requirement for design that is as varied as possible. Re-usable basic systems can easily be adapted to different software functions, use cases, or designs. This is an area where we also support our customers with our extensive experience in system and requirements engineering.

Compliance with standards, directives, and regulations is crucial in the appliances industry. All products must meet the recognized technical safety requirements. Safety certification covers fire risks, electrical safety, mechanical safety, and other risks associated with the product.
Electronic controls are becoming ever more complex. Many safety mechanisms which were solved mechanically in the past now need to be covered by software and hardware. This makes the approval process more complex. Diehl Controls has highly qualified teams with extensive experience of safety-related software and hardware.
Our control systems comply with the full range of approvals and certifications. That also helps our customers gain certification for their household appliances. We cooperate with a large number of testing and certification institutes, such as:
- Verband der Elektrotechnik Elektronik Informationstechnik (VDE)
- Underwriters Laboratories (UL)
- Canadian Standards Association (CSA)
- China Quality Certification Centre (CQC)
Thanks to good personal relationships with the test institutes, we can synchronize our own approval activities with our customers’ final certifications. That saves a great deal of time and money for the approval process.
On request, we can also provide a CB certificate for our control systems. This certificate enables our customers to access the global market without any additional tests. You can find more information on the CB scheme on the IECEE website.
Electromagnetic compatibility (EMC) is becoming ever more important in all areas where electronic switches are used. Today’s “invertization” of many appliance motors not only improves their efficiency, but also demands compliance with the applicable standard threshold values. This is especially important as restrictions become continually stricter and measuring instruments more precise.
In view of new standards and directives, wireless connectivity of all appliances poses entirely new challenges for the white goods industry. That is why EMC occupies a significant part of the development process. In all development locations, Diehl Controls uses state-of-the-art EMC booths for pre-compliance measurements.
What’s more, we cooperate with accredited laboratories so we can have our results confirmed whenever necessary. So, even in early development stages, we can test all aspects of EMC requirements and improve the design if necessary. Thanks to a long list of successful projects, Diehl Controls has the necessary experience to expertly deal with this complex aspect.
As a full-development provider, we offer our customers development in native CAD systems such as ProEngineer, Unigraphics, or SolidWorks. To keep pace with increasingly short development times, Diehl Controls applies a strategy of integrative product development. It is essential here to use the latest development tools.
We have been successfully using the simulation software Moldflow to ensure cost-effective, process-sensitive design of our plastics parts and to optimize tool concepts for many years. FEM simulations are a reliable aid in optimizing designs in terms of mechanical, thermal, or optical functionalities. They allow us to evaluate our concepts for potential risks in the early phases of product development. Furthermore, we can react with agility to changed customer requirements.
These simulation tools are instrumental in enabling our interdisciplinary Design-for-X (DfX) approach. For instance, the optical functionality of the overall mechatronic system depends not only on the selection of a specific LED, but also on the light conductor design and the choice of materials. Beyond the boundaries of hardware, software, and mechanics, we optimize systems and solve any interface problems in the early project phases.
