For Ecotap, I worked on the Standalone Payment Solution (SPS): a robust, independently installable payment solution for electric charging infrastructure in public environments. This project was not about concept development, but about making an existing design engineering-proof and translating it into a fully manufacturable product.

Project context

The Standalone Payment Solution is designed for permanent installations and can be mounted on both horizontal and vertical surfaces. When a fixed foundation is not available, a separate foundation can be applied. Depending on the application, a stand and a sign are available as optional accessories.

The solution is suitable for a wide range of environments, including residential complexes, workplaces, and parking facilities. Like other Ecotap products, the focus is on robustness, reliability, and long-term use in public space.

Variants

  • Freestanding model
  • Freestanding model with sign
  • Wall-mounted model

My role and responsibilities

My assignment consisted of translating an existing, partially incomplete product definition into a fully developed and manufacturable design. Based on STEP files and fragmented input, I rebuilt the complete mechanical design in a 3D CAD environment.

This included:

  • Building the complete 3D model and validating it for manufacturability
  • Creating a full technical documentation set, including drawings
  • Implementing DFM optimizations in alignment with suppliers
  • Performing mechanical qualifications and documenting them in reports
  • Engineering the packaging solution and coordinating it with all stakeholders

In addition to the design work, I was closely involved in supplier alignment. This extended beyond production topics to practical aspects such as transport, handling, and protection during logistics.

Result

The final result is a fully production-ready Standalone Payment Solution that aligns with Ecotap’s core values: extremely robust, modular in design, and suitable for long-term use in demanding environments. By technically consolidating the design and capturing it in a complete documentation set, the SPS could be reliably released for production and qualification.

This project illustrates my role as a link between concept, engineering, and realization: structuring incomplete input, taking technical ownership, and translating design intent into a manufacturable and validated product.
