IDEA 370 - Regenerative Design II

Knotle

 An object for resting, exploring the relationship between soft and hard materials

In designing new products, we often create massive amounts of waste, not just in the materials, but CO2 and other greenhouse gas productions from machinery, shipping, packaging, etc. 


This class was focused on how we might reconsider what is "waste" and what is "material" by reusing or repurposing materials considered to be "waste" into an object for resting, or put more simply, a chair.


An additional component of this assignment was that at least one automated processing component must be used in the ultimate production. This was so that we could envision how this project might potentially be scaled up for actual production in the market.

Inspiration

 

I took a look at the materials I was surrounded by for inspiration and to help me create my object for resting. Here is a picture of myself competing in the NESCAC 2025 Outdoor Steeplechase Championships. I use the hurdles to help me practice going over the barriers. 

 

 Knitting is a passion of mine, I picked it up during COVID and have found such joy in creating material from what begins as nothing. This image is of a cashmere patterned shirt I hand knit in Spring 2024. While I prefer hand knitting, table-top knitting is a no-carbon, automated machine that I could use in this project to help me design my object for resting in a timely manner.

In both of my materials I saw a great potential for adaptation and reuse. There were many old track hurdles from the 90s that were either broken or rusty, and my coach was willing to give them away. A few years prior, my grandma's friend was moving from her house into an apartment, as didn't have space to store all her yarn, much of which she had aquired at flash bi-annual sales. I gratefully received whatever yarn she could no longer store, which amounted to 7 large boxes of a various assortment of fluffy, frizzy, and even sparkly yarns. I have done my best to work my way through that stash, but could not possibly work quickly enough by hand to get through all of it. However, this was the perfect opportunity to put that yarn to use, as I would be using a table-top knitting machine to aid me in my production.


I felt these materials provided the perfect composition for a chair. The solid, metal framework of the hurdle provided structure and stability, enough to support the weight of a human. The yarn in contrast provided a soft, fluid cushion that was comfortable enough that a person would want to sit in it.

Initial Sketches

Some of these sketches were drawn prior to knowing what material I might use, however once I had determined that I was slightly constrained by the structure of the hurdle, which then influenced my design. Part of the process of repurposing materials is that there is only so much wiggle room to change or alter them, however this can actually help the design process move faster as you have pre-determined limitations, allowing you to narrow down your final ideas.

Future Iterations

 Using the Shima Seiki Robot, I could program it to knit different colors to inform users where the knit panel is supposed to meet with the hurdle. This would create a stronger relationship between the two entities, making the chair more cohesive overall.

Future Iterations

The Shima Seiki Robot would not only speed up the production process and minimize manual labor, but also provide more opportunity for customization.


If customers wanted specific colors or a different type of yarn, such as nylon vs. acrylic, the Shima Seiki could be quickly loaded with different yarns to meet their needs.
