Txog Random Puff 4D Paj Ntaub Tsoos Tsho

RandomPuff yog ib qho tshiab puffer uas siv 4D paj ntaub puffs rau khaub ncaws rwb thaiv tsev. Puffs yog thawj zaug fabricated tiaj tus thiab pop tuaj rau hauv domes thaum raug tshav kub. Cov activated puffs ntxiab huab cua ntawm ib puag ncig sab nraud thiab tus neeg hnav kom lub cev sov so. Txoj kev loj hlob no suav nrog kev tsim cov tsev qiv ntawv ntawm 4D paj ntaub cov khoom sib cuam tshuam ntawm 'active fibers' thiab 'static fabrics'. Cov neeg tsim qauv thiab cov neeg tsim khoom tuaj yeem siv cov cuab yeej tsim qauv tsim los ua haujlwm sib koom tes nrog cov neeg siv khoom kawg, tsim cov ntaub ntawv tshiab thiab cov qauv zoo nkauj uas yog cov qauv siv high-tech, tus kheej thiab ruaj khov.

Yam Tshwj Xeeb: Random Puff is a garment application leveraging the puffy transformation that traps air within the dome pocket to keep the body warm. The double curvature geometry becomes easily fabricated, and personalizable styling is available through the computational design process, which opens up a new design/manufacturing space for a puffy garment.
Qhov Loj & Ntim: 500mm x 30mm x 700mm. However, since it's a garment, it can be fold into the size of 300mm x 20mm x 200mm.
Cov Ntsiab Lus: 4D embroidery
Thev Naus Laus Zis Tsim Khoom: Heat-shrink thread. Neoprene. Machine embroidery. Processing visualizer.
Kev Sib Tw Tsim Qauv: First, the force balance between active thread and static fabric is a fundamental challenge. There is too much fabric out there with labeled information that does not necessarily lead to our purpose. Second, tension issues happen when new threads or fabric are introduced to the machine. It takes a while to calibrate, and sometimes break the machine if the thread is too thick/thin, or the fabric is too thick/slippery/crispy. Third, to achieve the maximized bi-layer bending, we want to vary the force on both sides so that the inner side does not constraint the outer side.
Kev Tshawb Fawb: Research background:
This research demonstrates how machine embroidery with heat-shrinking fibers enables existing fabrics to be augmented with morphing fibers.

Methods/Tools:
Similar to sewing, embroidery is a technique of interlacing upper and bottom threads with the substrate in between, but digitally. For the hardware, a desktop, hobbyist embroidery machine can easily execute wanted samples. For the software, I mainly explored PEmbroidery and Inkstitch for different purposes. PEmbroider is an open-source library housed in Processing that offers a procedural coding environment to generate detailed embroidered files at point and line levels. Inkstitch is also an open-source plug-in embedded in Inkscape that provides a graphical user interface, which is more friendly for primary users.

Results/Insight:
I started off the material characterization by testing different substrates with the same embroidery parameters. Out of 10+ fabrics, fabrics that are lightweight with high springness can hold the morphed structure better. A series of embroidery parameters were also tested systematically with stroke width, density, peak-to-peak distance, stitch spacing, and threading material. The fiber actuator can be tuned from crease(low res) to bend(high res) in a linear pattern. The fiber can be arranged in curves, origami creases, or arbitrary shapes to form more complex pop-up geometry.
Kev Txhawb Siab: Working at a NIKE shoe industry, I realized the challenge of transformation between 3D to 2D or vice versa. There's still no clear solution for the tedious, laborious, wasteful process from prototyping to production.

Working as a R&D at a carbon fiber company, I got to witness the power of machine embroidery, where it can digitally place fibers. This way, it can reinforce the artifact in any direction, replace the lamination thus reducing the material waste, and digitalize the process from start to end.
Lub Sij Hawm Ua Hauj Lwm: The project started in September 2021 and finished in December 2021 in Cambridge, MA, United States.
Txheej Txheem Ua Hauj Lwm: First, a closed-curve set of circles, squares, or other arbitrary shapes is generated within the area of a 2D clothing. Second, the design file will be translated to an embroidery file via Processing, a visual output, and procedural coding environment. Third, upload the file to a desktop hobbyist embroidery machine and start embroidery. Lastly, the garment comes out flat from the machine and users can customize where to activate the puffs by heating the embroidery pattern with a steamer or iron.
