이중 캡이 적용된 비타민 음료저장 병뚜껑 디자인 제안 -선행설계와 프로토타이핑 과정을 중심으로-

Abstract

The active ingredients of vitamins are easily deteriorated or oxidized when exposed to sunlight or if they contact oxygen. Both domestic and international companies add an extra amount of nutrients on top of what’s written on the label concerning that the nutrients of vitamin beverages might be compromised in the production and distribution process. This can indeed lead to excessive consumption of vitamins. Hence, this study sets up three objectives; 1) to protect vitamins from sunlight by designing a beverage lid with a storage unit, 2) to prevent vitamin oxidation by moisture, 3) and to ensure the product’s consistency of vitamin content and accuracy of ingredient labeling. Prior to design, products with vitamin caps and patented design with similar purposes to this study were investigated. Then the items with the same structures were grouped for comparative analysis. Based on the analysis of the Pain Point in the previous cases, the bottle cap was designed to reflect the following three things. 1) Structural design of the cap itself without additional structure at the mouth of the bottle, 2) A structure in which contents can be dropped regardless of vitamin form, 3) induce users to behave naturally through a simple structure and intuitive design. The devised design has a dual structure, divided into upper and lower parts. A semicircle-shaped vitamin storage unit is placed on the upper part, and the corresponding semicircular space exists in the lower part so that vitamins can fall. In order for the contents to be dropped simultaneously as the cap opened, the upper part spins 180 degrees independently first, from the lower part starts to rotate together until the end. Through prototyping using a 3D printer, later experiments are conducted to test whether the product works with all forms of the vitamin such as solid, powder, liquid.
