In the second version of the design, I have kept the simple interface as always. This is one of the most critical value proposition of my medicine box, because I believe that no old man would want a complicated operation panel, so the pursuit is also to ensure that the basic functions can be achieved with the most simplified operation.
According to the opinions given by the classmates in the class. In the new version, the motor has also been replaced. It has changed from the original one-way motor to a micro servo motor. The biggest advantage of this motor is that it can rotate clockwise and counterclockwise. In the first version, all lids had to be closed manually by the user. With the help of the micro servo motor, the lid can be closed automatically after a certain period of time. This effectively avoids the problem of elderly people taking repeated medication due to poor memory and not remembering if they have taken medication or not. In addition, closing the medication box in time also prevents dust and airborne water vapor from entering the box and contaminating or moistening the medication.
(For demonstration purpose, I’ve reduced the delay time)
In the 3D model, different colors are used for the morning box and the evening box, so that the medication can be easily refilled according to the box. In addition, a drive shaft has been added to the connection between the lid and the box. The volume of the engine box next to the medicine box has also been expanded. The purpose of this is to ensure that there is enough space to fit the motor, the circuit board, and the battery. Also, to make sure that the speakers would be loud enough to come from the machine. I’ve also left a lot of hollow dots in the mechanical enclosure. This maximizes the sound transmission to ensure that the elderly can clearly hear the reminder to take their medication. In addition, according to Patrick Scerri’s advise, the medication reminder will include family members’ voices that acts as the reminder in addition to the elderly’s favorite music. In my grandmother’s conversation, I found that the reason why she didn’t like the sound of the alarm clock was that the sound of the mechanical alarm clock was very noisy and cold. I believe that family greetings and reminders can bring more warmth and make her more willing to use the machine.
In addition, there are little grids in the box. Each time elders take medicine, they only need to take the medicine in one grid. The advantage of this is that even if they need to take multiple drugs at the same time, they don’t have to worry about making mistakes. It can hold up to 25 days of drug dosage, and many drug cycles are four weeks a course of treatment, so in most cases, it can accommodate a course of medicine amount. And only need to be refilled every 25 days.
