I also experimented with using rubber bands to supplement the pulling back force. Unfortunately the force from a single rubber band was too strong limiting the amount of rotation. I plan to explore wrapping the band around the smaller gear with the string or using a chain of rubber bands to test if those work better.<\/p>\n\n\n\n<p>Turning the gear wraps four strings around the smaller gear, pulling the fabric from 4 directions at the same time.<\/p>\n\n\n\n<p>The concept for this prototype would be a cover for an overhead light that switches it from a more ambient light to an overhead reading light. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"768\" height=\"1024\" src=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5248-768x1024.jpg\" alt=\"\" class=\"wp-image-7917\" srcset=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5248-768x1024.jpg 768w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5248-225x300.jpg 225w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5248-1152x1536.jpg 1152w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5248-1536x2048.jpg 1536w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5248-973x1297.jpg 973w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5248-508x677.jpg 508w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5248-scaled.jpg 1920w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<p>However, because the felt I initially used was not very stretchy, I also explored concept where the felt was replaced with a pleated thinner fabric.<\/p>\n\n\n\n<p><strong>Second Direction<\/strong><\/p>\n\n\n\n<p>One thing I wanted to explore, however, was a larger scale of actuation. With the first idea, I felt the movement of the fabric was not that great. Keeping the same principle, but this time limiting it to 1 direction of force with two strings, I decided to explore a window blind-like concept where the fabric provides a privacy screen for people studying in the library.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"768\" height=\"1024\" src=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5249-768x1024.jpg\" alt=\"\" class=\"wp-image-7919\" srcset=\"https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5249-768x1024.jpg 768w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5249-225x300.jpg 225w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5249-1152x1536.jpg 1152w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5249-1536x2048.jpg 1536w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5249-973x1297.jpg 973w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5249-508x677.jpg 508w, https:\/\/courses.ideate.cmu.edu\/16-376\/s2023\/wp-content\/uploads\/2023\/03\/IMG_5249-scaled.jpg 1920w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<p>In particular, I was interested in the booths on the second floor of the library along the windows.
