Quincunx boards and features:What is a Quincunx and how do you pronounce it?Quincunx demonstration techniques. Quincunx Faq Pricing The top part of the quincunx has a reservoir for holding the beads. The bead release lever will drop five beads with every stroke, or a single bead can be discharged. The moveable funnel, which represents adjustments in a process or a shift in the mean, is spring loaded to hold it in position until it is moved. In control chart terms, a shift in the funnel is an 'assignable cause'. The pins in the two different types of pin blocks, simulate the 'chance causes' of variation in a process. One pin block simulates a normal process, and a second pin block simulates an improved process with less variation. Unlike some lesser brands, our Quincunx units are designed so that the pin block slides in from the side into a mitered slot, thus preventing binding were the wood to swell. Each pin is accurately located and securely imbedded in its plastic base. The channels of our units are painted white for high visibility in a classroom session. Each Quincunx also has two or three gates which hold the bead distributions in place for comparison. The sturdy Plexiglas face can be marked with water-based transparency markers or chart-pack tape to depict tolerance or size denominations. (Note: Pin Block guide shown on WD-5 is a rubber band)
Model WD-7 QuincunxOne of the key elements of Total Quality Management is the concept of continuous improvement. So why shouldn't that also apply to the design of training aids? Well it has, and the result is the Model WD-7 quincunx. After listening to the "voice of the customer" it was determined that the quincunx could be made even more effective by incorporating certain new features like:
Adjustable Pin BlockOne of the best features of previous model quincunx units has been the ability to simulate improved process capabilities with a narrow distribution pin block. With the creation of the adjustable pin block the quincunx can now simulate not two, but four different distributions. This is accomplished by loosening the lock screw and sliding different rows of pins into, or out of alignment. The more rows that have aligned pins, the narrower the distribution. This is equivalent to improving process capabilities. Accessories:If you travel with your Quincunx and would like to check it with your luggage but don't know how to protect it ... then the HC-5 hard cover carrying case is what you need. It conveniently holds a model WD-5,WD-6, or WD-7 Quincunx, an extra pin block, and a SB-5 Sampling Box.
