SPEED trainer - EMS device
As part of this project, an EMS device was developed over several stages. Based on technical specifications, the concept, design and prototypes were systematically refined until a mature, ergonomic and production-ready solution was achieved. The work illustrates the complete process of structured product development.
Concept
The Speed Trainer is a compact EMS device designed for portable use. The task was to develop a robust, intuitive system that integrates the existing electronics into an ergonomic and clearly structured housing. The design was based on a true-to-scale 3D model that defined all the relevant components.
Design
Several design variants explored material combinations, operating logic and manufacturing options. The focus was on good legibility, a clear button layout and a design language that conveys a high-quality appearance whilst also being suitable for small-batch production. The variants ranged from polygonal housings to minimalist metal-and-plastic combinations.

Prototyping
Models and prototypes were produced using vacuum casting and deep-drawing processes for functional testing. Operating sequences, viewing angles, tactile feedback and the positioning of buttons and controls were adjusted through an iterative process. User feedback was incorporated directly into the optimisation of the ergonomics.
Final product
The final EMS device combines a compact design, intuitive operation and high build quality. Aluminium and plastic components form a robust housing, whilst the ergonomic layout of the controls ensures safe and efficient use. The design has been optimised for small-batch production and is fully production-ready.
