Workshops & Tutorials

All workshops and tutorials will be held Sunday, August 25th and have limited capacities.

Description: The practice of design is rapidly changing. The increasingly digital footprint of design and the growing prevalence of high-powered computing introduces new opportunities for making use of advanced computation. Simultaneously, the rise of complicated cyberphysical systems presents designers with challenges that are unprecedented in terms of scale, multi-disciplinarity, and complexity. In this way, human-AI teaming is not only an exciting opportunity for engineering design, but it is also quickly becoming a necessity. This workshop brings together leading researchers in AI/ML, formal methods, design science, human-computer interaction, and other fields to discuss emerging trends and future opportunities in human-AI teaming for engineering and design.

Description: Participants will learn the principles of advanced gear design and simulation and will interact with state-of-the-art computational tools for the virtual generation of gear drives and the application of tooth contact and finite element analysis (TCA & FEA) to evaluate their mechanical performance. Topics covered in this tutorial include the application of micro-geometry modifications to avoid edge contacts and absorb errors of alignment, the free-form design of gear tooth surfaces, the evaluation of the loaded functions of transmission errors and mesh stiffness as root-cause of noise and vibration, the compensation of errors of alignment caused by shaft deflections, and the advanced design of spiral bevel gear drives.

Description: Generative AI relies heavily on substantial and high-quality datasets to address domain-specific challenges. However, acquiring hand-crafted design knowledge proves challenging, particularly due to the time constraints faced by designers. Designers often hesitate to invest additional time in documenting and organizing explicit design knowledge, such as sketches, models, and inspirational images. Additionally, tacit knowledge, such as trade-offs and prioritization, is typically shared informally among designers working on the same project, lacking proper documentation.

1. Sorting Challenge: Sorting design documents becomes a formidable task due to the varied and abstract design workflows, shaped by individual designers with diverse perspectives.


2. Processing Challenge: Handling car design documentation proves to be intricate, given the complex nature of the product comprising over 20,000 parts and employing diverse data formats throughout various developmental stages.


3. Collecting Challenge: The imperative of confidentiality and the preservation of originality in car design results in a decentralized and somewhat closed design process, presenting difficulties in gathering comprehensive and openly accessible documentation.

The process of designing products is influenced by a range of factors, spanning from clear specifications to personal experiences. Assuming a structured design process, we can categorize these factors impacting the workflow and outcomes.

This workshop aims to explore innovative interaction methods and techniques to address the difficulty of collecting design knowledge. Using a practical case study focused on designing a new car, the workshop will delve into various dimensions of design knowledge, such as metacognition (Lawrie, Hay, & Wodehouse, 2022), tacit and explicit (Tsoukas, 2012; Grandinetti, 2014), scientific and emotional Bratianu (2014), confidential and public (Ahmad, Bosua, & Scheepers 2014).

Description: This workshop will introduce attendees to a new computational and physical prototyping framework for innovating and inventing mechanical motions using a web-based motion design software tool and a home-grown hardware kit to support the needs of students in classes, such as Freshman Design, Kinematics of Machinery, Mechatronics, and Robotics. While the hardware serves as a reference hardware, the software also allows exporting robot part geometry for laser-cutting or 3D printing.

Description: Additive Manufacturing (AM) demonstrates the huge potential to revolutionize the industrial base. Still, the speed of adoption has not matched that potential for impact, often because the processes and parts are not as predictable and reliable as needed for critical applications. Two emerging technologies, digital twins and advanced data analytics and management, have the potential to break this logjam. Digital twins enable the in-situ AM process monitoring to ensure predictability and reliability. Advanced data management tools allow integration of the plethora of data generated by AM machines, making this data Findable, Accessible, Interoperable, and Reusable (FAIR) to a broader community. Statistical tools and machine learning approaches can then efficiently and effectively use this knowledge to analyze an AM process’s data and identify inconsistencies and anomalies. A data management infrastructure, together with analytical tools, is critical to improving the tool maturity level of a DT. This tutorial will introduce the data management tools and DT workflows for students, engineers, and enthusiasts interested in AM, data management, and digital twin technologies.

Description: From design conceptualization to production perfection, the Design for Manufacturing (DFM) workshop will guide participants through the entire manufacturing lifecycle, equipping them with the tools needed to navigate the complexities of modern engineering. The workshop is a set of principles and it is the culmination of years of hands-on engineering experience and educational expertise. The workshop is a scenario-based learning workshop, where participants will explore two scenarios for each topic: one where the engineer lacks knowledge of DFM principles and another where they are well-versed in DFM. Through practical exercises, participants will gain a comprehensive understanding of DFM concepts and their practical applications in real-world engineering scenarios. The sessions will cover DFM role in various phases of manufacturing a part from design to production/assembly to quality control.

Description: Recent developments in the 2D sketcher capabilities of modern CAD systems allow the creation of dynamic or moveable constrained geometry. Dynamic geometry is a new tool for the design of planar linkages and provides the opportunity for new synthesis methods. One method exploiting the advantages of this is Pole and Rotation angle Constraints (PRC). It has the intuitive, visual advantages of graphical methods and the fast and accurate advantages of analytical methods. PRC provides a single approach for every planar four bar linkage synthesis problem that is not overconstrained. Since CAD tools are commonplace in academia and industry there is direct carryover from education to industrial practice. Learn this breakthrough method to solve linkage synthesis problems faster and minimize trial and error since you can easily see thousands of possible solutions. The class will focus on the exact synthesis of linkages for rigid body guidance, point path, function generation and any combination of these tasks.

Description: This workshop uses the interactive Racism Untaught toolkit and is focused on methods for understanding and dismantling racialized and oppressive design. It starts with an exercise on power and privilege in a variety of systemic oppression. We then move to the first step in the toolkit, Context, where participants are given the cards that outline over 150 different elements of racism, sexism, ableism, and capitalism. This allows participants to analyze an artifact, system, or experience and learn how we perpetuate racism and oppression in our everyday lives and then how to break down racialized design. Then, participants further examine a system, artifact, or experience with step two, Define, used to understanding theories and methods that define the oppressive societal problem further. Lastly, participants move to step three, Ideate, walk away from this workshop with ideas on re-imagining a form of racialized and oppressive design specific to their field.

Description: The purpose of this workshop is to disseminate the findings of NSF CMMI funded research on "Theory-Grounded Guidelines for Solver-Aware System Architecting (SASA)" through an information session and a collaborative multi-player educational game.

Systems engineering aims to architect complex systems such that subtasks can be completed efficiently in parallel, and later integrated to form a system that delivers value. Traditionally, complex system development programs assume that interdisciplinary nature of these problems require expertise with domain specific knowledge. Hence the goal is to formulate the best technical architecture given operational needs, without considering who is solving different parts of the design problem and how they are engaging in the design process. Then, resulting subproblems are assigned to experts within traditional organizations (e.g., NASA, Lockheed, Ford). This view constrains the potential trajectory of design activities while simultaneously overlooking the potential benefits of engaging non-expert solvers. Consequently, complex system development processes are notoriously over budget and schedule; while technical innovations are constrained within the boundary of subsystems.

However, improvements in sharing platforms, the rise of "gig" work and broader adoption of open innovation tools call into question the efficacy of traditional approaches to architecting. In fact, the joint consideration of problem decomposition and solver assignment decisions could simultaneously improve design process outcomes in terms of performance, cost, and schedule; while enabling opportunities for novel solutions to be identified and realized.

The purpose of this workshop is to illustrate the fundamentals of SASA, along with the heuristics and design strategies enabled by this perspective, through an information session that is supported by a collaborative multiplayer educational game. The multiplayer game will first illustrate these concepts in a simple golf setting; then demonstrate how these ideas apply to an interdisciplinary robotics design problem. By the end of this workshop, the participants will have an improved understanding of SASA principles, along with heuristics and strategies to leverage SASA for tackling complex real-world design problems. The workshop promises a fun and engaging opportunity for industry professionals and academics to better utilize the human capital at their disposal, innovate, and gain the competitive edge in complex system development.

Description: There are many sound reasons why environmental issues should be considered in the design and product development process. They help us meet customer and legislative requirements. They put us in a stronger competitive and commercial position. They play a major part in ensuring we maintain innovative credibility.

But most of all, they help us achieve our ambition of reducing the overall environmental impact of our products across their lifecycle. Here we want to demonstrate the environmental impacts of bearings in terms of embodied energy (energy consumed during production), carbon footprint, and eco-indicators of bearing range for a variety of application. New bearings designed on the concept of green design include seal technologies (hard seal coatings and surface design); light-weight parts (polymers), and "lub-for-life" thin film lubrication, which makes re-lubrication unnecessary throughout a bearing's lifespan. An estimated 50 billion bearings are in use at any time and reduction in energy consumption by a 307ndash;70% depending on the type of use can be tremendous savings in energy. It would consequently reduce carbon dioxide emissions in atmosphere as well as savings in resources and money. It will also lead to enormous reduction in the lubricant disposal. Ships trading in the world's oceans and seas can eliminate both operational and accidental stem tube oil pollution, while also reducing their operating costs.

In this age of Industry 4.0, the design principles and practice must include the nature of industry today not 100 years old practices. The topics included are most of the concerns and ideas discussed briefly above.

6. Green design and manufacture of sustainable products in the age of Industry 4.0

Description: Recent advances in design tools have transformed CAD models – and the processes by which they are created – into rich data troves for researchers investigating collaborative design processes and developing the next generation of AI driven design tools. This workshop will feature presentations from researchers from a few different fields doing informatics research with CAD data, as well as a panel discussion about the future of design tools.

The hands-on portion of the workshop will allow participants to work in focus groups to explore a few shared CAD data sets, brainstorming research questions and analysis methods that could provide insight into design processes or inform the next generation of CAD tools. Participants will walk away with an understanding of how to acquire CAD data from models and processes, as well as ideas for future research projects and collaborations.

Attendees are encouraged to bring a laptop to participate fully in the hands-on portion.

Description: As AI tools gain popularity, designers are actively integrating them into diverse design workflows, including user research, idea generation, and design variations. Despite their widespread use, there's a lack of awareness regarding biases in outputs, such as demographic and cultural biases, and potential harm could arise when these biases are incorporated into designs without careful consideration. Especially with generative AI tools such as ChatGPT and Midjourney being rapidly integrated not only into professional design practice but also education, there is a pressing need to raise awareness about bias risks and establish guidelines to evaluate and mitigate their impact in the use of the tools in design. This workshop aims to foster discussions on identifying, measuring, and mitigating biases in generative AI tools. After introducing existing biases found in the outputs from the tools, participants will engage in structured activities to experience the design process using the tools. Through reflective discussions, they will brainstorm a framework to measure bias impact and strategies to mitigate them. Based on the outcomes, we will collaboratively develop guidelines on how to use generative AI tools for design with an awareness of bias.
