The kinetic sculpture is an important aspect of modern urban landscapes and installation art. However, designing such a sculpture needs much time, imagination, engineering knowledge and even rework, which restrains iterations of design and imagination of artists. To allow designers to have a holistic perspective in design, and to simplify and accelerate the design process, we proposed a system to assist designers to build kinetic sculpture digital prototypes from sketches rapidly. The system simplifies the design pipeline as sketch processing, skeleton generation, unit assignment, and motion simulation. Different from other design tools, our system liberates designers from detailed modeling and animation. Therefore, they can focus on perfecting visual effects. User cases show that our system can spark the creativity and accelerate design process both for professional and inexperienced designers, and can generalize the pipeline to other kinetic applications.

Exhaustive Study

Abstract Photonic engineered materials have benefitted in recent years from exciting developments in computational electromagnetics and inverse-design tools. However, a commonly encountered issue is that highly performant and structurally complex functional materials found through inverse-design can lose significant performance upon being fabricated. This work introduces a method using deep learning (DL) to exhaustively analyze how structural issues affect the robustness of metasurface supercells, and we show how systems can be designed to guarantee significantly better performance. Moreover, we show that an exhaustive study of structural error is required to make strong guarantees about the performance of engineered materials. The introduction of DL into the inverse-design process makes this problem tractable, enabling optimization runtimes to be measurable in days rather than months and allowing designers to establish exhaustive metasurface robustness guarantees.

Abstract Computer aided design tools are gaining popularity in industry due to their ability to model the geometric aspects of products. This has shown substantial benefit for reducing the need and expense of building physical prototypes and allowing parts and tooling to be manufactured directly from these models. However, the current capabilities in existing CAD tools for modeling assemblies are quite limited. In this paper we introduce a representation for describing interfaces between parts within hierarchical assemblies for capturing functional and physical mating relations. This representation is designed to support automated reasoning and automated generation and modification of assemblies. It is also designed for use with very large assemblies, compactly representing the interfaces of parts and assemblies that are reused within larger assemblies. We describe how this representation is used in our prototype design system, Genesis, for designing aircraft systems.

Analysis Of Motion

A current study regarding the development of a rehabilitation device for lower extremity is presented. The device is specifically designed for rehabilitation of post-stroke patients who encounter walking weakness. The rehabilitation device is categorized as an active device that is power-driven by a DC motor. Its design was the outcome of improvements to counter the problems existed in the a newly developed prototype. A motion simulation was used to ratify the motion capability of the proposed design in the modelling design process. Analysis of kinematic and dynamic behavior of the motion simulation has been carried out. The smoothness of the mechanical movement and the linear velocity provided by the device are acceptable as additional work of the design process. Based on a statistical analysis, the study found that there is no significant difference from the motor torque requirement even though the angular velocity of the motor was changed substantially.

Structure Development

This paper lies within the integration of an eco-design method adapted to the Innovation structure at a car manufacturer. The environmental constraints in the automotive industry are more and more important (European emission standards for exhaust emissions, European directive on end-of life vehicles …). Eco-design is a new manner to design products related to the concept of sustainable development, which combines economy and ecology and put the environmental criterion alongside the classical criterions of design. The goal of this study is to identify the specifications of a strategy for integrating the dimension “Environment”. This strategy is applied in the innovation process thanks to eco-design tools which are the learning vectors for an organization, and therefore support a learning process. This process is structured with the interactions between the management of firm, the environment department, and the design team. Therefore we first make a synthesis of the different classifications of eco-design tools and use two categories: diagnosis and improvement. Second, as our goal is the integration in the Innovation structure and within a design process, we analyze some design process models and highlight the RID (Research, Innovation structure, Development) concept. Third, the main practices of several car makers are synthetized and a focus on three of them (Volvo, Ford, and Volkswagen) is made; we link their strategies with the concept of RID. Finally in the fourth part, we propose a model of a strategy for integrating eco-design practices based on the three examples and supported by a learning process.

Sketching and prototyping of design concepts have long been valued as tools to support productive early stage design. This study investigates previous findings about the interplay between the use and timing of use of such design tools. This study evaluates such tools in the context of team design projects. General trends and statistically significant results about “sketchstorming” and prototyping suggest that, in certain constrained contexts, the focus should be on the quality of information rather than on the quantity of information generated, and that prototyping should begin as soon as possible during the design process. Ramifications of these findings are discussed in the context of educating future designers on the efficient use of design tools.

Creativity And Innovation

Engineering graduates in advancing economies are not only expected to have engineering knowledge, but also use them in creative and innovative ways. The importance of visual thinking has been critical for creativity and innovation in design. However, today’s engineering students are proficient in detailed design tools but lacking in conceptual design and ideation, and engineering curricula needs to develop a more effective framework for teaching visual thinking. In this paper, we report our efforts to embed principles of design thinking and visual thinking practices, like McKim’s “seeing, imagining and drawing” cycle [1]. We use a toy design course in mechanical engineering for our pilot study as a scaffold for introducing these principles in an engaging, creative, and fun environment. We introduced free-hand sketching as a tool for visual thinking during the design and communication of concepts. We also report the impact of these changes through information gleaned from student feedback surveys and analysis of design notebooks. We use our findings to propose ways to provide the students with a set of balanced techniques that help them in visual thinking, communication, and design. An improved implementation of this experience is discussed and future work is proposed to overcome barriers to thinking and communication.
