About Reusable 접이식 컵

Reusable은 외출 시 음료를 마실 때 사용하도록 디자인된 접이식 컵입니다. 이 컵은 주머니나 가방에 들어가는 콤팩트한 형태로 접힙니다. Reusable은 식품용 실리콘과 BPA 프리 플라스틱으로 제작되었으며, 사출 성형 방식으로 성형되었습니다. 컵의 용량은 250ml이며, 너비 87mm, 높이 122mm입니다. 컵을 펼치려면 상단 테두리를 제자리에 고정될 때까지 위로 당기면 됩니다. 컵을 접으려면 테두리를 납작하게 접힐 때까지 아래로 밀어 내리면 됩니다. Reusable은 일회용 컵을 대체하는 대안을 제시하며 쓰레기 감소에 기여합니다.

Production Technology: The foldable cup design was achieved through iterative prototyping using CAD software. We employed injection molding for precision in mass production, utilizing food-grade silicone and BPA-free plastic to ensure safety and durability.
Design Challenge: The toughest challenge in this design activity was achieving a balance between compactness and durability. Creatively, we faced the obstacle of ensuring the cup could fold efficiently without compromising its structural integrity. The final concept of the foldable cup emerged as a response to countless iterations, material testing, paper prototyping, and 3D printing.
Research: The final concept of the foldable cup emerged as a response to countless iterations. In the process, a huge role played sculpting through various types of prototyping. Paper prototypes were used for proportion and geometry relationships, and 3D printing prototyping with soft plastics was used to test shape and thicknesses. Followed by extensive research on materials from which to manufacture.
Inspiration: Reusable's journey began with a simple question: How can we make eco-friendly choices effortlessly integrated into our routine? Inspired by the beauty of simplicity and functionality followed by the quest to create a solution that combines convenience with sustainability. Reusable boasts a unique collapsible design that transforms it from a full-sized cup into a compact, pocket-friendly form factor.
Project Duration: The idea was born in 2019, but the project commenced in January 2023 and concluded in April 2024. The design and development phases took place in Bulgaria. This timeline allowed for extensive research, prototyping, and user testing, ensuring the final product met high standards of functionality and sustainability.
Operation Flow: The foldable cup is easy to use. To operate, simply expand the cup by pulling on the top rim until it locks into place. To collapse, push down gently until it folds flat.
