Challenges
After we finished our design, we discused about challenges of our design.
1. Challenges of Function
The first challenging part is the functional part. One of the tasks is a magnet. Our team concluded the restraint device was indispensable through many discussions. In the process, he sought ways to make it easier to restrain patients. As a result, our team found a solution that helps the medical team subdue the patient through magnets. But, as IoT matrix function was added later, there remained a challenge that magnets could have a bad effect on electronic devices. Our team wanted to use an electromagnet as a magnet. By doing so, we tried to solve this problem by making it in ordinary times be a state of non-magnetism and adjusting its magnetism appropriately. But it was not a complete solution. In order to make our team's design better, we need to find tools to help medical staff instead of magnets, or use a strictly calculated level of magnetism.
2. Challenges of Economics & Utility
The second challenge is economic feasibility and effectiveness. In economics, there is a problem with IOT mattresses themselves. IOT mattresses are definitely existing technologies, but they are hard to be commercially available and are also expected to be expensive. Therefore, it is necessary to calculate and execute the costs and benefits in the process of introducing the IoT matrix.
Next, there is a problem of effectiveness.Although the above survey showed some positive responses, it remains a challenge whether the bed designed by our team in the field will be effective. According to a study of nurses and doctors working at actual medical institutions, the most desired things for actual medical staff in the safety area are securing initial response personnel, deploying guide personnel, and contacting systems for emergency external support. (Song, Lee, Kim, 2013) Therefore, it may be more appropriate for the Objective that improving other parts of the bed is "protecting the patient and the medical staff from the sudden behavior of the mentally ill." rather than installing a restraint device on the bed. But our team's bed design is to achieve its goal by improving the design of beds that exist in any hospital room without additional manpower. Therefore, I think that if we improve the challenging points, we will have a great result in the long run.
3. Challenges of Human Right
The last is the issue of human rights. Restraining a patient, monitoring indirectly through sensors, or checking the patient's condition through IoT mattresses can cause human rights problems. This also can be the most important issue in a way. However, the issue of human rights is a too deep and sensitive discussion to deal with in this project. Therefore, on this project, we paid a little attention to human rights issues but did not over-consider them. This issue should be discussed not only in our project but also in society as a whole.
