(Long version with process of development)
This project grew up rather from a dream than from an existing problem. Looking to the future, we were analyzing trends such as “Augmented Reality” and “Internet of Things”, finally we came to the idea of a smart working space, interacting with a user. Imagine that your desk recognize you, and prepare everything, that you need for work and after you finished the desk will clean up itself, putting everything on its place. This idea of self cleaning work space was the most resonated with people we were talking with, so we focused on this gap in user experience. Designing a pen sorting device is just a first little step on the way to the self cleaning work space.
It took us nearly 4 months and 3 working prototypes to design this device.
We started from design research and decided to focus on a working spaces. During the secondary research we were investigating how people organize their desks, what innovative solutions are already exist and what future trends about interactive furniture could be predicted. During the primary research we were asking people about their needs, problems, personal design solutions in organizing work place. The outcome of the research bring us to realize couple important points:
1. The Self Cleaning Desks is a most desirable dream of our audience.
2. Huge number of custom designed creative solutions were about organizing and storing desk equipment such as pens and pencils. This means that, people are not satisfied with existing market products.
As a result we focused on designing a self organizing solution for pens.
On a second stage through sketches and prototypes we were searching for the general pen delivering principle and defining components of our device. We come up with 4 for different concepts and choose the one that was the most compact, most simple, cheaper in production and easy-to-use.
After the basic framework and working principle were tested, we focused on color detecting process and testing electronic and mechanic components. We went through number of iterations where prototyping was going hand in hand with 3D modeling. Developing first prototype we’ve tested at least 5 pen delivering mechanics, 3 shapes of upper container and 2 configuration of rotating component (a part of pen delivering mechanics). In a first prototype we decided to use color sensor to identify different markers. But we were unsatisfied with color sensor precision, it can distinguish 5-7 colors one from another. Sensor works unstable, was over-sensitive to the lighting and couldn’t identify analogous colors.
For the second prototype we’ve choose a different principle of color detecting. We’ve took black&white line sensors and make black stripes on our markers which forms a binary code. Five stripes forms five bits which allows to identify up to 30 markers with 100% precision. An additional sixth sensor allows to identify directory of reading the code if you put marker another orientation.
Our first prototype was too bulky but can hold only 10 markers. Developing a second prototype, we doubled capacity by placing markers in two columns. This requires us to design a special rotator which drops markers to the left or to the right side of both chamfered bridge, depending on the defined place of a marker.
Developing last prototype we improved styling and accuracy of work of all components. Calibrating the movement of a bridge we designed zero-position button to send a feedback of a first and lowest position of the bridge. That allows a system to calculate the following position of the bridge from the starting point.
We used Arduino UNO as a brain of our system. One step motor moves belt with bridge. 180deg Servo motor rotates part with sensors.
