关于客户
本案例研究中的“客户”是印度浦那的马哈拉施特拉理工学院 (MIT)。麻省理工学院浦那分校成立于 1983 年，是印度顶尖的工程学院之一。该研究所致力于为学生提供适当的资源和环境，以解决当今社会面临的最具挑战性的工程问题并找到解决方案。该项目由麻省理工学院的一群本科生承担，在麻省理工学院浦那分校副教授 Girish S. Barpande 先生和麻省理工学院设计学院交通设计副教授 Chaitanya Kachare 先生的指导下开展工作。
挑战
印度浦那的马哈拉施特拉理工学院 (MIT) 面临着设计、制造和测试四旋翼无人机 (UAV) 的挑战，该无人机使用拓扑优化来减轻重量并增加强度。该项目是由一群本科生在教师的指导下进行的。目标是利用车辆的无人驾驶特性提供的设计自由度来增强车辆的性能。该团队的目标是找到一种简单快速的解决方案，以找到增强四旋翼无人机所需的结构改进。该挑战还涉及在不添加制造约束的情况下处理拓扑优化产生的设计复杂性。
解决方案
该团队在设计过程中使用solidThinking Inspire 来优化无人机设计空间，并创建了两种针对无人机进行3D 打印的新型轻量级设计。他们从基于电子设备、组件和有效载荷的设计计算和封装空间的简单一体式机身结构开始。使用了两种设计方法：多阶段优化过程和基于无人机基本力学的简约设计。通过在与原型配置相似的现成机身上进行实时测试来验证负载情况。然后使用 PolyNURBS 工具去除尖锐轮廓和应力集中点，对优化设计进行细化和准备制造。该团队得到了位于普纳的 DesignTech Systems Ltd（一家领先的 CAD/CAM/CAE/PLM、增材制造技术和解决方案提供商）以及 Stratasys 3D 打印机的支持。

IoT Data Analytics Case Study - Packaging Films Manufacturer
The company manufactures packaging films on made to order or configure to order basis. Every order has a different set of requirements from the product characteristics perspective and hence requires machine’s settings to be adjusted accordingly. If the film quality does not meet the required standards, the degraded quality impacts customer delivery causes customer dissatisfaction and results in lower margins. The biggest challenge was to identify the real root cause and devise a remedy for that.
