The Prioritivator is an elevator the prioritizes on servicing the handicapped first, regardless of which level they are at. Hence, the name.

What is the problem?

Firstly, the problems faced by many handicapped people is getting into the elevator. Sure, it has no problems on its own, however, when it comes to a peak hour, many people would be rushing to get into the elevator to be where they want to be.

This would result in the handicapped, especially who are in wheelchairs, being left behind as there would be no space left.

The Solution

The Prioritivator provides the solution to helping the handicaps getting into the elevator first, by making it reach to their current level. This would help them reach their destination, such as a home in a high rise building, or their workplace, especially even large hospitals.

How does it work?

Handicapped people will be given a card that is exclusively given to people with disabilities. All they have to do is tap their card to a scanner that is placed on the side of the elevator door. Once scanned, the elevator will be notified, if there are no passengers in the lift, it will prioritize on arriving at their current level, ignoring other calls from the different levels in the building. Once the elevator reaches the level, it will resume its normal function and accept all the other calls after picking up the handicap.

How can this impact the globe?

Data gathering can be a huge help in impacting the handicapped community. Whenever handicapped persons tapped their cards to the scanner, the data that includes the timing, place, date of usage will be recorded. Gathering data on disabled users will improve efficiency and have an accurate output. Property owners, establishments or even the government can use this data to pinpoint areas to further improve accessibility for more of the handicapped.

How can this be produced?

Instead of having to reinstall the elevators for the prioritivator to work, the elevator can have an extra program that coexists with the existing program of the elevator. The program will be added by USB or a dedicated device to configure the enhancement to the elevator. However, this may not work with old elevators that use hard relays. Since nowadays, elevators are programmed with C++ and Programmable Logic Controllers, configuring the priority program into the original elevator would be feasible. Installation of the program would be relatively more easy with cooperation with elevator companies.

Moreover, Card screeners will be installed on each level and communicate with each other wirelessly, using each other as a relay to transmit the data to both the PLC and to the internet to store.

Accessing the data can be easily done via a web browser so data can be reviewed easily from anywhere.

What makes it innovative?

Instead of having to install another elevator, simply adding this Prioritivator configuration would be cheaper if the building wants to give more accessibility to the handicapped, just by adding card screeners and adding an extra program to the original program that is stored in an elevator. Furthermore, an extra enhancement could be added, record data of the elevator usage as well. Recording the number of breakdowns it had, or the amount of usage in a month. These data can help elevator companies to see what to improve in their elevator efficiency.


Recently, I have learned more about networking and have actually implemented it in real life. The particular networking protocol was TCP socket servicing and even Modbus TCP and it encouraged me to learn more. Furthermore, I and my teammates have made a working mock elevator that demonstrates the Prioritivator. We wanted to take an extra step and challenge ourselves into further improving the prototype that incorporates communication via the Internet, emphasizing the theme of the Internet of Things. We wanted to better our skills as engineers, programmers and hope to benefit other people at the same time. That is why we joined this competition and hope to learn more from attending this.
