Good's Logistic Inc. manufactures wood pallets with sizes ranging from 30x48 in2 (76x76 cm2) to 48x48 in2 (122x122 cm2). It uses new wood boards with thicknesses varying between ½ in and 1 in. In addition, the company recycles old pallets to reproduce new ones. By means of an electric metal saw the employee cuts the nails fixing the wood pieces together. The metal saw vibrates horizontally, and the employee pushes the pallet against this saw, which is not a safe operation. There is a non-negligible corporal risk because of the metal blade and sparks produced by the friction between the saw and the nails. Moreover, because of the resistance of the nails and the vibration of the saw, a continuous strong push is required. Furthermore, the employee wastes a lot of time in the process of removing the nails. The company would like to improve its productivity, to reduce manual manipulation and to make the operation safer and more ergonomic. A comprehensive solution is required, in form of a safe and user-friendly system removing nails from wood. To do so, the idea consists in manufacturing a table involving a magnetic field. It is well known that an electromagnet can generate a fairly strong magnetic field. Less widely known, however, is that it is possible to greatly intensify a magnetic field, at least temporarily, by using an explosion to compress it. Currently, to the best of our knowledge there is no commercial system providing such an adaptive system. Moreover the situation presents research challenges since a new intelligent system is needed that does require replacing the present company's electric saws. We propose, through research, to design and implement an efficient manual/automatic user friendly system, which must be adaptable to the different sizes of wood pallets and offer a comfortable work environment for operators.

Good's Logistic Inc.生产尺寸从30 x48 in 2（76 x76 cm 2）到48 x48 in 2的木托盘 （122 x122平方厘米）。它使用新的木板，厚度在1/2英寸和1英寸之间变化。此外该 该公司回收旧托盘以生产新托盘。通过电动金属锯的手段，雇员削减 把木头钉在一起的钉子。金属锯水平振动，员工推动托盘 用这把锯子锯，这可不是个安全的手术由于金属的存在， 锯和钉子之间的摩擦产生的刀片和火花。此外，由于 由于钉子和锯的振动，需要连续的强力推动。此外，员工还浪费了 在拔指甲的过程中花了很多时间。公司希望提高生产率， 手动操作，使操作更安全，更符合人体工程学。一个全面的解决方案是 需要，在一个安全和用户友好的系统的形式删除钉子从木材。要做到这一点， 制造涉及磁场的桌子。众所周知，电磁体可以产生相当大的电磁力。 强磁场然而，不太广为人知的是，有可能在一定程度上大大增强磁场， 至少是暂时的，通过爆炸来压缩它。 目前，据我们所知，没有商业系统提供这种自适应系统。 此外，这种情况提出了研究挑战，因为需要一种新的智能系统， 取代目前公司的电锯。我们建议，通过研究，设计和实施 高效的手动/自动用户友好系统，必须适应不同尺寸的木托盘 并为操作者提供舒适的工作环境。
