  • 90 Deg 

    Bamboo Chair Within Bag for Urban Daily Lives


  • Background

    Try to find a simple way to solve an urban daily life problem of requiring a temporary seat by mixing different elements from multi-fields. 90 Deg is a bag with two types; an accessory people would use every day with the feature of fashion design while combining with the thinking of product design and the user experience on the design of the bag. 

    試圖透過整合多重領域元素以簡潔的方法解決需要臨時座位的城市日常生活問題。90 Deg 是人們每天都會用到的時尚設計配件,同時以產品設計思維結合包包的設計與用戶體驗。

  • 90 Deg has won the Golden A' Design Award from A' Design Award & Competition. Also, it is very honourable to be able to be featured on Behance in Product Design and Student Show. Thanks to people who help during the process of making 90 Deg and to the judges. This work is my graduation project of bachelor degree in industrial design, and it took me a whole year to test every kind of possibilities. I will appreciate you taking the time to read this project, and please enjoy it! Thank you!

    90 Deg 榮獲 A' Design Award & Competition 的 Golden A' Design Award。 並且,非常榮幸於 Behance 平台獲得精選 Product Design 及 Student Show 的類別。

    感謝許多熱心善良的人們在 90 Deg 的發展過程提供幫助使得產品能實現,同時也感謝評審的肯定眼光。這個產品的專案是我的工業設計學士學位畢業設計,歷經一整年的時間測試各種發展可能性。

  • Holder  /  Laminated Bamboo

    Typically, the products of bamboo are presented by bending strips and sticks. However, the holder is laminated bamboo, made from layers of tiny bamboo sticks and bound with glue. The speciality of laminated bamboo is that its physical property provides a mighty strength, and it can fulfil the requirements of 90 Deg.

    支架材料  /  層積竹材

    90 Deg 的支架採用層積竹材,將竹片層層堆積黏合成的材料,避開了單純使用竹條或竹管而有節點的問題,更能以本身的物理特性提供堅固不易脆的優勢,提供更多造型開發的可能。

  • The holder made from laminated bamboo can withstand the sitting weight, conducing to only one straightforward step to change between the bag and the chair. Also, the application of modern industrial manufacturing (CNC machining) on a traditional craft material makes the product be able to produce in mass production.



    Hollow out the middle reinforcement of the holder with the logo of 90 Deg. It helps to make the weight of 90 Deg lighter and have more detailed feature with the identity of the product.


  • Also, the natural bamboo material makes every holder be one of a kind, creating its unique feature while it can be produced by the spirit of precision and craft.


  • There is enough space for a 15-inch laptop and documents.


  • Free postcard design for exhibition use.
