The brief was to design a 2.4m x 1.2m display for fixed installation on-board ship. It is essentially a wheel around the outer rim of which are listed all the 200+ names of the cruise ship’s destinations, categorised per continent. Each location is allocated a number that corresponds to a point on the central globe of the world. The purpose of the display is simply to provide passengers with an easy point of reference to the scope of the ship’s activity.
Although manually operated and of relatively simple construction, the display needed to satisfy important performance criteria. Literally central to the design is a HepcoMotion® ring slide system that revolves around the 500mm diameter globe.
HepcoMotion® rings are more commonly incorporated into automated systems. However, when Paragon factored in the potential intensive public use of this ship’s display and its need for smooth movement, the robust HepcoMotion® product was judged to be ideal for the task.
“Positioning accuracy was not an issue for this application as the wheel is turned by hand so the user can view the graphics,” explained Paragon’s Director Mark Pyrah. “However what was important is the ring’s ability to run smoothly and provide a long, maintenance-free working life, despite its low cost.”
HepcoMotion® is unique in its ability to manufacture rings from .1m in diameter to 8m and beyond. Paragon Creative’s requirement was for a commercial ring of a modest 1.2m in diameter. However thanks to a new technique, large HepcoMotion® rings can be assembled from segments whilst maintaining concentricity or smooth running of the finished product. This means virtually any diameter ring can now be specified from the company.
