They had a obsoletion engineer (BSOE) on staff.  Lack of quality is job 1 (sorry Ford).

I wonder if this is an oversight or a deliberate design decision to save money. Either way, it's amazing that the company let the product out the door that way.

Garage door openers move the heaviest moving object in your home, so it is surprising that the designers would omit a load bearring from the rotating object.  However, it is still common to see metal on metal contact in consumer items.  Ususally, the difference between professional and a consumer model from any manufacturer is the quality of the shaft bearrings.

The marriage of mechatronics know-how and advanced software tools is refining dynamic machine performance using measurements and innovative motion algorithms.
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
The machine is claimed to be the largest and most powerful electric pipe-bender on the market, exerting nearly 500,000 lb-ft of torque.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
