从智能玩具和家用电器到个人机器人，机电设备在我们的日常生活中发挥着越来越重要的作用。我们的目标不是依靠大规模生产的小工具，而是让休闲用户能够根据自己的需求和偏好定制设计此类设备。为此，我们提出了一个计算设计系统，利用数字制造的力量和负担得起的电子产品，如传感器和微控制器的出现。我们系统的输入包括所需设备形状的3D表示和一组用户首选的现成组件。基于此输入，我们的方法生成一个优化的3D打印外壳，可以容纳所需的组件。为了自动创建这些设计，我们形式化了一个新的时空模型，该模型捕获了整个装配过程，包括设备内组件的放置，安装结构和附件策略，组件必须插入的顺序以及无碰撞装配路径。使用此模型作为技术核心，然后我们利用工程设计准则和有效的数值技术来优化器件设计。在一项用户研究中，我们发现我们的系统可以有效降低临时用户在创建此类设备时面临的进入障碍，该研究也强调了设计此类设备的挑战。我们进一步证明了我们的方法的多功能性，通过设计和制造三个不同功能的设备。
From smart toys and household appliances to personal robots, electromechanical devices play an increasingly important role in our daily lives. Rather than relying on gadgets that are mass-produced, our goal is to enable casual users to custom-design such devices based on their own needs and preferences. To this end, we present a computational design system that leverages the power of digital fabrication and the emergence of affordable electronics such as sensors and microcontrollers. The input to our system consists of a 3D representation of the desired device's shape, and a set of user-preferred off-the-shelf components. Based on this input, our method generates an optimized, 3D printable enclosure that can house the required components. To create these designs automatically, we formalize a new spatio-temporal model that captures the entire assembly process, including the placement of the components within the device, mounting structures and attachment strategies, the order in which components must be inserted, and collision-free assembly paths. Using this model as a technical core, we then leverage engineering design guidelines and efficient numerical techniques to optimize device designs. In a user study, which also highlights the challenges of designing such devices, we find our system to be effective in reducing the entry barriers faced by casual users in creating such devices. We further demonstrate the versatility of our approach by designing and fabricating three devices with diverse functionalities.
