关于客户
本案例研究的客户是苏州三星电子有限公司,这是一家中韩合资企业,开发和生产冰箱和洗衣机等主要家用电器。该公司不断寻求在不牺牲顶级性能的情况下减少产品材料用量来引领竞争的方法。为了控制成本,该公司正在考虑将某些型号的冰箱门盖的成分从 ABS 工程塑料更改为高抗冲聚苯乙烯 (HIPS)。然而,在物理可靠性测试过程中,HIPS 盖板出现破裂,导致该公司寻求解决该问题的方法。
挑战
开发和生产大型家用电器的中韩合资企业苏州三星电子有限公司的冰箱门盖面临着挑战。该公司正在考虑改变某些型号冰箱门盖的成分,以降低成本。传统上,ABS工程塑料用于制造上下门盖。然而,为了控制成本,该公司寻求使用高抗冲聚苯乙烯(HIPS)代替 ABS 来制作注塑盖。不幸的是,在物理可靠性测试期间,HIPS 覆盖层在温度循环过程中破裂。在门盖顶面的中间观察到裂纹,从门盖的前边缘开始。苏州三星的工程师对材料、结构和注塑工艺进行了分析,以确定破裂的原因。他们发现材料的变化是导致裂纹问题的因素之一。
解决方案
为了分析热膨胀和收缩过程中门盖上的应力,工程师使用了 HyperMesh 和 RADIOSS,它们都是 Altair HyperWorks 计算机辅助工程工具套件的一部分。这些工具使工程师能够创建冰箱门盖温度场的计算机模拟。模拟分为两种情况:从室温下降到低温和从室温上升到高温。模拟分析表明断裂源于低温循环期间的收缩。材料由ABS改为HIPS后,安全系数下降,最大变形增加。然后,工程师们评估了防止开裂的方法,首先是增加门盖顶面的厚度,并添加垂直和水平肋形式的加强筋。第二个方案延长了肋条的长度和高度,事实证明可以将门盖的安全系数提高到2.0,与ABS材料的安全系数相同。

Leveraging the IoT to Gain a Competitive Edge in International Competition
Many large manufacturers in and outside Japan are competing for larger market share in the same space, expecting a growing demand for projectors in the areas of entertainment, which requires glamor and strong visual performance as well as digital signage that can attract people’s attention. “It is becoming more and more difficult to differentiate ourselves with stand-alone hardware products,” says Kazuyuki Kitagawa, Director of Service & Support at Panasonic AVC Networks. “In order for Panasonic to grow market share and overall business, it is essential for us to develop solutions that deliver significant added value.” Panasonic believes projection failure and quality deterioration should never happen. This is what and has driven them to make their projectors IoT-enabled. More specifically, Panasonic has developed a system that collects data from projectors, visualizes detailed operational statuses, and predicts issues and address them before failure occurs. Their projectors are embedded with a variety of sensors that measure power supply, voltage, video input/ output signals, intake/exhaust air temperatures, cooling fan operations, and light bulb operating time. These sensors have been used to make the projector more intelligent, automatically suspending operation when the temperature rises excessively, and automatically switching light bulbs. Although this was a great first step, Panasonic projectors were still not equipped with any capability to send the data over a network.
