How I Designed This

The piece that I created is meant to be used as an accessory to makeup brushes such as mascara and eyeliner for the audience who experience low motor control or high anxiety. This work has a handle for multiple positions since there are different means of using it ie. overhand or underhand grip. This was designed for a more modular experience and to help with the struggles of positioning at angular angles.

This work was influenced by the seven principles of universal design for an adaptive product. The first principle is equitable in use where this product can be used for other cylindrical small objects such as toothbrushes or a phillips head screwdriver. Since the 3D printed prototype is fully functional, this is also created more of an equitable design since it can be useful for the user. The second principle is flexibility in use where I have talked a bit about that above with the different grip styles and rotation of the chuck head for different angles. The prototype also is flexible where it can grip between different girths of an object which helps the user create their own way of using the form. Within the handle there is a symmetry which accommodates left and right hand users for a flexibility in use. The third principle is simple and intuitive use which could be redesigned down the prototyping phase. There is an intuitive use within the object since I designed it to use symbols rather than using words which can be seen within the lever mechanism that holds the ball joint in place. I decided to use the “0/I” binary to show when the tightening lever was on or not. There is an intuitive use since different types of handles are used for different motion which notify the user that there is something different to do. Within a possible remix, I had thought on how to include a radical slider which could function for the gripping of the chuck mechanism so the user could simplify the process of the object by resizing the three jaw chuck within the handle. The fourth principle is perceptible information which is also talked about within the “0/I” binary on the tightening handle. There was also consideration within the final design of the prototype to impregnate terracotta clay with sand which would create a textural sense for the object which would aid in perceptible information. The fifth principle is tolerance for error which was thought within the design of the modulation of the tightening handle since if the angle was not right for the user’s face then there would be the ability to alter that. Within a precision CMC cut of the ball joint, there would be an ability for the ball handle to slowly move down since this would create a better experience for the participant. The sixth principle is low physical effort which would be planned within later implementation of the design since with the materialization of the form, there would be the ability to smooth out tightening and loosening. This could also be seen within the proposed mechanism of a radical slider at the top half of the handle which would minimize the use of placing the form down before using it. The last universal design principle that I thought of while designing the form was size and space for approach and use. The form is meant to be used within the hand is larger than a makeup brush to design for someone that has a hard time with gripping smaller objects. There was also a consideration of implanting a few metal slots for a weighted back part that could have created more size within the use. Within the organic design of the brush handle, I also design to create space for different shapes of fingers and thumbs.

Overall, I am pretty happy about the form and wish for a larger concentration to formulate this into the more developed stages of a prototype. I was ambitious with this project since I wanted to learn how to model a ball and joint and venture more into organic design within 3D modeling. I want to remix this work with the sand impregnated clay on the handle and search into the radical slider that would alter the size of the chuck mechanism. I would like to thank mdkendall for letting me remix their three jaw chuck mechanisms.
