In this paper, the FREECAD 0.14 was used for modeling conventional Selfie-stick and the newly proposed Selfie-stick design. The purpose of this paper is to demonstrate the utility of FREECAD 0.14, which is open-source and still in development for further use. After modeling the conventional Selfie-stick, CatiyaV5 was used to assemble FREECAD 0.14 drawn elements. Main advance in newly designed Selfie-stick is the portability. To improve portability of the Selfie-stick, folding mechanism was adopted from folding LED stands. Several mechanisms were adopted to improve user convenience as well. Ansys 14.0 was used for structural analyses of conventional Selfie-stick model and the newly designed model as well. Several simplifications for the models were needed to process the analyses. When analyzing the newly designed model various materials were used one by one to find compatible composition. Using Aluminum alloys for the stick and the hand grip was found to be compatible. FREECAD was useful for suggestion of the newly designed model but not so much useful to design an actual product. Various efforts would make FREECAD the best choice for industrial use for free as it is named.

The objective of the study is to develop selfie sticks to enhance portability and prevent error of pushing mobile phone button. The main target of selfie sticks is women and the size of selfie sticks is too big to put it in their bag. Also when people put mobile phone in a selfie stick, people push its button easily. Sometimes mobile phone is turned off or the volume is controlled because of pushing its button. The researcher focused on designing a solution that enhances portability and preventing error of pushing the button. The researcher understood structure of selfie stick. It consists of a mobile phone supporter and a length adjuster. The researcher designed the mobile phone supporter for enhancing portability and the length adjuster for preventing to push the mobile phone. The researcher designed a part which connects a mobile phone supporter with a length adjuster and made selfie stick fold. Also, sponges are partly put on the mobile supporter. It can reduce situation of pushing the mobile phone button. The selfie stick design from the study has an opportunity to distinguish using the product and carrying it and have people use the selfie stick conveniently.

FREECAD was useful for suggestion of the newly designed model but not so much useful to design an actual product. Various efforts would make FreeCAD the best choice for industrial use for free as it is named.

Corresponding to the high consumption rate of the selfie stick for cell phone camera, the design of the product is becoming diverse. However, relatively low cost selfie stick models are not strong enough to stand the weight of the cell phone. This results into a bending of the stick or the accidental fall of the cell phone by the failure of the holding unit. As a solution to the problem, design of selfie stick that is structurally strong enough to stand the weight of the cell phone with the minimum weight for the portability is proposed in this paper.

Smartphone users are 15 billion in all round the world, and Korean smartphone users are estimated at 40million people to 83% of the Korean population. Selfie stick is most popular item among 20, 30's age users. And they use smartphones more than 90%. In survey they express inconvenience of using selfie stick. Inconveniences are as follows. * Heavy * Handle is inconvenient. * Mistiming during taking pictures * the range of shooting is not enough. In this paper the first improvement was that rod strength is slightly stronger. The second we divide a grip into 3 parts. If 3 parts are unfolded, these can use for tripod. We use deflection Interpretation for main Finite Elements Method program.

Currently, selfie stick, a monopod take selfie photographs, got its popularity. Cradle used to connect selfie stick and smartphone usually uses electric force of spring to get smartphone fixed. But, using electric forces makes it hard to attach and detach smartphone from the cradle and gives possibility of smartphone falling down. CoQue suggests new solution of smartphone cradle by using cable tie (patent number US 8407863 B2) instead of electric force. It will give more easy and stable way of using selfie stick.

We present selfie stick case design, which can protect upper part of Selfie Stick. Many of current products are damaged when it is carried without cases, especially upper part of the product, because protection case is irrelevant to handle in urgent or frequent use of the product. To solve this problem, we design the case part which is attached to stick. For designing the part, we considered functionality, aesthetics, portability and profitability.
