What is Anti-Collision Detection: The Basic Rundown
The obvious reason for detecting a collision between your desk and some object during height adjustment is to avoid costly damage to either. Examples of collision objects include door knobs, low shelves, trash bins, file cabinets, and armchairs.
The circuitry typically works by detecting a sudden spike in current draw from the motors in the desk leg’s lifting columns. So if the desk hits a soft object, like a cushy chair back that leans easily, the current spike won’t likely be detected. But if the desk runs into a door knob it should immediately stop and back off an inch or so, before any major damage would be done.
Do You Really Need Anti-Collision Detection?
some brands will cancel the anti-collision detection on their height adjustable desk products in order to make their price lower and to win more market. In order to prevent the issues on damaging things by accident, they also cancel the one click lifting feature. so when you bought a desk you have to hold pressing the button to lifting the desk, you actually don’t need the anti-collision detection. But some brands will ask the manufacturers like us to keep the one click lifting feature in the control pannel, that with some setting, it will be allowed to set one click lifting work, that make us very anxious，so we will refuse to cancel the anti-collision.
Anti-collision feature is very necessary, if your electric standing desk can move with one click. Because the chair is very possible go to underneath the desk, if your chair has wheels. Also Anti-collision can protect the expensive computer or devices on your desk, that desk will slant if something big underneath the desk.
How Well Does Anti-Collision Detection Work?
The effectiveness of anti-collision detection varies wildly between manufacturers, between desk lines, and even depends on the size of desktop and the distribution of weight relative to the lifting columns and crossbar underneath.
As a broad statement, the collision detectors that do work tend to work better when the desk is being raised than when it is being lowered, based on our observations from testing dozens and dozens of standing desks in the lab over the years. This may simply be due to the fact that an ascending desk consumes a lot more current as compared to a descending desk, so the current spike is likely to be larger.
