Innovation behind the screens
Central Station Digital Media (CSDM)
Displays for North-South Metro Amsterdam
CSDM holds the media concession for the Amsterdam metro network. As part of this concession, it is responsible for fitting the North-South line section with advertising displays this year. CSDM asked us to develop the display housing and installation of Phase 1. This involves large format displays (98”) that are integrated into the walls of the stations. There were strict requirements for the glass facade wall, the various components and the installation space. The end result fully complies with the intended visual quality that the architect (Benthem & Crouwel) defined together with the Municipality of Amsterdam.
The real innovation is mainly on the inside
Our design engineers came up with an innovative solution for the minimal space in the wall recess so that the displays can easily be opened and closed. This solution is technically smart and means that maintenance can be carried out quickly and efficiently.
After unlocking the housing, the weight of the glass and the display is stabilised by a spring mechanism. This allows maintenance to be carried out by one person. In the unfolded position, the maintenance technician can open the display door 180° (parallel to the facade wall), which means passing travellers are never obstructed.
Mechanical complexity: that's also part of npk
The idea was soon on the table; the real challenge was to make it technically feasible. Due to the weight and the limited space, a range of forces are exerted on the spring mechanism and the hinge. Calculation models are essential for the success of such a project. It’s all a matter of calculating, testing, adjusting and calculating again. That way, we can translate and optimise the dynamic behaviour with exactly the right profiles, hinges and springs to make the principle work. Another great achievement by our engineers.
From design to installation in two months
After the development process comes the realization. Based on our final drawing packages, the screens and electronics of CSDM, VDL Industrial Modules produced and installed 37 display housings.
