Ephicas a spin-off company from the TU Delft created an innovative product, a device that installed beneath a semitrailer can reduce up to 9% of both, CO2 emissions and fuel consumption. This eco-minded product can easily represent a total of 20 tons less carbon emissions per year per truck. The focus of the project was the Flow conductor, the most important and a patented component of the Ephicas SideWing. The challenge of this project was to take the product, still on a testing phase, to a better interaction and easier installation. Main issues with the current Flow Conductor were: Custom made components only for the part, increasing costs. A rotating pillar and different locking mechanism, than the rest of the side wing. Hard to position as suggested by the company. As the flow conductor needed to rotate, it needed to be installed afar from colliding objects, therefore wrong positioning. Its door-like functioning had the side-effect of drivers leaning on the wing; and the misuse of the landing gear crank, damages the mechanism. Drivers needed to open the flow conductor to reach the landing gear, (vertical supports to keep the trailer standing when no truck is attached.)
