About Taboo Cadair Bioddiraddadwy

Wedi'i ysbrydoli gan y pelfis benywaidd dynol, mae'r gadair tabŵ wedi'i gwneud o glai di-dân organig diraddadwy arbennig, sy'n seiliedig ar y cysyniad adeiladu daear rammed traddodiadol Tsieineaidd, gan ddefnyddio algorithmau optimeiddio topoleg i wella'r strwythur cyffredinol i sicrhau y gall wrthsefyll 1000 Nm o ddiffyg grym wrth gynnal y strwythur bionig. Dyfeisiwyd y deunydd a ddefnyddir yn y gadair i ymateb i'r alwad bresennol am arbed ynni a lleihau allyriadau, a gellir ei ddiraddio i wrtaith organig mewn safleoedd tirlenwi o dan amodau addas.

The Recognition

About the Gwobr Efydd A' Design Award

Mae Taboo Cadair Bioddiraddadwy yn enillydd Gwobr Efydd A' Design Award, cydnabyddiaeth hynod fawreddog a roddir i ddyluniadau rhagorol sydd yn nodedig am greadigrwydd, dyfeisgarwch a chraffter. Mae enillwyr Efydd yn arteffactau medrus iawn a thrawiadol o greadigol sydd yn dilysu profiad helaeth, dychymyg a dyfeisgarwch eu dylunwyr. Disgwylir i Taboo Cadair Bioddiraddadwy fod yn wrthrych uchel ei fri, a edmygir ac a anwylir, sydd yn nodedig o broffesiynol ac arloesol.

Unique Properties: The chair is made of a special non-fire clay, which has a material strength comparable to ABS plastic. It can completely degrade to organic fertilizer within two years in an industrial landfill environment.
The structure of the chair was topologically optimized. After setting the parameters of force, support and pressure values, the redundant parts were eliminated.
After testing, this chair can withstand 100kg of longitudinal force.
Dimensions & Packaging: 420mm x 260mm x 450mm
Tags: Clay, Biodegradation, Topology Optimization, Carbon Neutrality
Production Technology: In the design phase, we used the Finite Element Analysis plug-in in Rihno for topology optimization calculations to eliminate redundant parts.
After the prototype was printed using 3D printing, we disassembled it and turned out more than 70 plaster molds. Finally, the finished product was produced using the casting process.
Design Challenge: Additives and clay shrinkage adjustment
Skilled use of topology optimization
Development of robotic arm 3D clay printing technology
Generation of internal crystal structures
Research: Research on new materials and molding process
A biodegradable high-strength no-bake clay material is formulated under the requirement of low carbon emission. It avoids the high energy consumption of modern industrial production while achieving the sustainable use of resources. To achieve maximum material utilization with the support of topology optimization algorithms.
Through the experimentation in the field of furniture, we will mature the production process and eventually reinvent the world by entering the construction industry with the concept of raw earth construction.
Inspiration: The chair shape is inspired by the human female pelvis.
The technique of the chair material is inspired by the paper clay used in ceramics art, and the characteristics of the clay are changed by adding additions.
The material was developed in response to the current call for energy saving and emission reduction, with the intention of completing the 'construction' of the world from a new perspective, based on the traditional raw clay.
Project Duration: The project started in June 2020 in Nanjing and finished in February 2022 in Nanjing.
Operation Flow: The chair is made of raw clay, which can be found everywhere, and by adding additives to it, it can achieve great strength without being fired, and it is biodegradable, turning into organic fertilizer and recycling after being disposed of in landfills.
