Yes, you read that right. I assert we will need to miniaturize our products’ burden on buildings while having bigger experiences and faster delivery times which requires stronger materials. 

Remember Ironman’s super-cool digital screens inside his ocean-side lair? Well today, thyssenkrupp announced that our service technicians will use HoloLens technology in its elevator service operations worldwide.

There is no getting around it. If your building is two stories or hundreds of feet, you are going to need an elevator. You have to meet the American Disabilities Act codes but what you don’t need is a complicated elevator system to travel just a few feet.

The term “smart city” can be open to interpretation. Here are a few prerequisites established a few years ago.  A smart city uses technologies to be more intelligent and efficient when using resources.

thyssenkrupp is currently putting the finishing touches on the installation of 30 elevators and 2 escalators that will serve 52 floors at River Point, a new office tower located on a prime piece of property overlooking the Chicago River.

We get it. The waiting is the hardest part. Once you touch the elevator button it seems like you just wait. You have to wait for the door to open. You have to wait for it to close. Then you have to wait for everyone else to get on and off.  The truth is a lot happens after you touch that button and before the doors open.  Popular Mechanics’ Jesse Dunietz does a stellar job of offering an explanation in The Hidden Science of Elevators.  But if you don’t want to wait to get to the end of the article, here are five high points.

1. Elevators use algorithms (step-by-step procedures for accomplishing a task) to determine where the elevator goes and when. Elevators are programmed to respond to button pushes or requests for service. But there can be many requests or button pushes made at once so the elevator has to “decide” where to go first.

2. When it comes to elevator routing, decisions have to be made based on what Dunietz refers to as the pain index. Simply put, whose pain caused by waiting takes priority. Is it the guy who has been waiting the longest in the lobby? Or is it the crowd forming on the 7th floor.  Would passengers rather wait one minute and ride for 30 seconds or vice versa?  And elevators operate under speed and time constraints. A great deal of analysis and mathematical computation goes into optimizing elevator performance. If you are into those kind of details, you can read more here.

3. In low and mid-rise buildings, elevators can operate using the approach of collective control. So if a passenger is inside or ahead of the elevator who wants to travel up, keep traveling in that direction. Once those passengers have exited, switch directions to take the other passengers down. Or stop and wait for a call.

4. In taller buildings that have more passengers, things get more complicated. Engineers have developed controllers (that is the computers brain) that can optimize performance to adapt to tenant demands.  For example, they can dedicate elevators to serve certain floors, provide priority access and send more elevators to specific floors at periods of high demand.

5. The pinnacle system to handle elevator traffic is destination dispatch.  This advanced dispatching system  directs passengers to the elevator that will get them to their destination in the shortest travel time. By grouping people together based on the floor they are traveling to, the number of stops is reduced, thereby improving the efficiency of the building's elevator traffic. With these types of systems, there are no buttons to press. You use a kiosk to select your floor and the system tells you what elevator to board.

One thing for sure, if you are the guy that pushes the button repeatedly, you are not helping. It really does not speed things up. So please stop that.
