Do you really think there would be a big design stage at this point in the product cycle, especially when the fogging was caused by a badly crushed o ring doing manufacturing.
I work in HVAC and I tried to fix the Oring...In fact, we changed it with a softer and bigger one, in order to make perfect contact...but was not ORing...Then we tried to see what is the issue...At 6th exchange we received one sealed, but also was fogging after only 5 days...
So we have changed the approach...we used a industrial air dryer and lowered the room to 15% humidity, opened the lens, sealed all chamber with exterior silicone rubber grade, injected Argon in sealing to eliminate air as much as we could, then apply again a row of silicone rubber at points of contact with back case.
Never seen again fog, even in -10 degrees flights or +6 degrees super humid days.
But this took a full working day and a lot of nerves consumed, as we needed to improvise each step (we work with big HVACS, not small camera chambers )) ).
I doubt DJI will ever do that, as the process takes a lot of time for a drone to be solved... |
