<p>A pressing environmental problem is used as the prompt in a creativity study. Increased adoption of wind-energy technology helps address climate change, but also requires disposition of retired wind-turbine blades that are not easily recycled. In past study iterations, participants were asked to identify potential reuses in a Wind-turbine-blade Repurposing Task (WRT). In all iterations, study participants consistently struggled with correctly incorporating the large physical size of wind-turbine blades in their reuse concepts. The Alternate Uses Task (AUT) is commonly used to measure creativity and asks participants to identify uses for much smaller objects like bricks and paper clips. The current work explored whether an AUT can be adapted as an intervention to help overcome the scale challenge in the WRT.</p><p>Students in a fourth-year undergraduate engineering design course (N=29) underwent both of two conditions, a scaled-AUT intervention and a control, typical-AUT before the WRT. AUT fluency and flexibility (number and categories of ideas) were significantly lower in the scaled AUT than the typical AUT. This result supports that object scale more than unfamiliarity is the main WRT challenge, since the AUT objects were relatively common. Notably, correctly scaled WRT concepts significantly increased after the scaled AUT, supporting the intervention's effectiveness. Finally, the WRT is proposed as a standard design-study task whose solutions help address a real-world problem.</p>

ASME 2021 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference (IDETC/CIE2021)

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
