Wireless E-bike charger

 

The course Advanced Embodiment design (AED) is a compulsory course of the master Integrated Product Design. In this course students focus on the embodiment design phase of the product development process, which starts from a program of requirements and working principles and ends with a validated prototype of a product.

The Delft based start-up Tiler asked an AED group of six students to develop and validate an embodiment for their wireless charging system for e-bikes. This task also entailed researching the most suitable user group for the new innovation. 

First, the charging technique needed to be analysed in order to define parameters in which the charging product could perform optimally.

Since the charging technique, which makes use of electromagnetic power transfer, was still being developed, the embodiment needed to be flexible enough to withstand future changes and upgrades.

After the completion of the course AED, Tiler had te desire to further develop their charging tile. Over the course of the summer of 2020 different prototypes of the charging tile were developed. The environment of these tiles would be side-walk pavement and therefore must be weather and mis-use proof.
