C-lite

2020

Security guards’ job responsibilities are not easy types and they face numerous challenges. One of their biggest challenges is operating at night and they need better lighting equipment a.k.a. flashlights. After having completed many in-context user interview and observations, three key problems were identified:
Number of equpment they have to carry during night patrols makes it hard to carry flashlight every time.
Inconventient design of many flashlights is not suitable for their context of use.
Weather conditions. such as rain and winter cold further intensifies previous problems and demotivates bringing flashlights.

C-라이트(C-Lite)는 빛이 나오는 머리부분을 회전해 손전등으로도, 몸에 부착해서도 사용할 수 있는 다기능 플래시라이트입니다. 상황에 따라 바꾸어 사용할 수 있는 세가지 밝기를 제공하며, 순찰팀이 사용하는 경우 여러대를 연결해 충전할 수 있는 모듈형 충전 스테이션도 제공됩니다.

During ideation stage, enormous effort was put into the idea of allowing users to use flashlights without hindering other activities. That is when the idea of transformative design became the core of the project, trying to ideate a product which can held in hands like any other flashlights, but also transform into a wearable product, allowing users to accomplish other tasks with other equipment. The sketching process took a tremendous amount of time as many options were considered while remembering the relationship of other elements such as charging stations, iconography and etc. While doing a ton of sketching, the visual look of the flashlight was being considered as well, thus, a moodboard was created with several adjectives.

After having chosen visual styles and having many sketches, CAD models were constructed. The evolution of CAD models is impressive on its own, having 10+ variations by the end. The initial stage of CAD prototyping combined with 3D printing allowed to check many issues with the concept, especially issues concerning manufacturability and physical ergonomics of the prototype. which consequently led to changes to some elements with each iteration. The final prototype solved countless issues with previous prototypes, while keeping visual choices from the moodboard and user needs from user research.

Unique features and case uses

The final prototype brings together features that should be able to solve the unique problems that were found during the research process. Namely:


Modular charging docks – allows flexibility with any team sizes of security guards.
Hand-held & Wearable – The biggest focus of this project, allowing security guards to be able to use flashlights even when they physically can’t hold one in their hands.
Several lighting modes – allows guards to switch the brightness of the product based on their context of use.

개인, 팀 할 것 없는 편리한 사용 – 모듈식 충전기는 여러대의 C-라이트(C-Lite)를 동시에 충전할 수 있도록 해 개인이나 팀 할 것 없이 편리한 사용이 가능합니다.

손전등으로 혹은 웨어러블로 사용 – 빛이 나오는 머리쪽을 회전시킬 수 있기 때문에 손에 들거나 옷에 걸어 사용할 수 있습니다.

세가지의 모드 – 고유한 사용 환경을 조사해 만들어진 C-라이트(C-Life)의 세가지 밝기는 다음과 같습니다: 소프트 라이트, 순찰 모드, 눈부심 모드
