設計說明：「循環設計」的目的是透過設計改變人類社會，而這種改變主旨志在追求人類社會的正向永續發展，簡言之設計必須要有意義，才能產生價值。除了理解循環設計解決方案外，在日常生活材質選用上，無論是可再利用、不可利用或可回收、不可回收，皆在這次的設計中有相關的探討。另外，由過去的線性思維轉向循環思維，設計師更可以從中探索未來新的高值化設計和創新。
全球有將近三分之一人口依然以燒柴作為炊煮方式；這樣的烹飪方式不但造成使用者身體上極大的危害，也是造成地球急速暖化的幫兇之一。Two triangles是一款新型態的爐具設計，透過爐具內部的二次燃燒結構有效降低煙霧排放，外觀則利用回收塑料製成，成本低廉、環保永續。內部製造由先進國家提供堅固耐用的不銹鋼及能大量生產模具技術，爐具外觀的製造則跳脫一般生產線的製造方式，而是利用全新的商業模式提供發展中國家更多工作機會。
Design Summary: The purpose of "Circular Design" is to change human society through design, and the purpose of this change is to pursue the positive and sustainable development of human society. It means design must be meaningful in order to generate value. In addition to understanding circular design solutions, the selection of materials for daily life, whether it is reusable, unusable, recyclable, or non-recyclable, is discussed in this design. In addition, from linear thinking in the past to circular thinking, designers can explore new high-value design and innovation in the future.
Nearly one-third of the world’s population still uses wood for cooking; This cooking method not only causes great harm to the user's body, but is also one of the accomplices of global warming. Two triangles is a new type of stove design that effectively reduces smoke emissions through the internal secondary combustion structure of the stove, and the appearance is made of recycled plastic, which is low-cost, environmentally friendly and sustainable. Internal manufacturing is provided by advanced countries with durable stainless steel and technology for mass production of molds. The stove appearance of the manufacturing is a different way of the general production line manufacturing method, but uses a brand-new business model to provide more job opportunities in developing countries.
