"That's a good summary IMHOPerhaps to add:If possible use as little as possible different thread sizes (each needs a specific tool).Turning is cheaper than milling hence, rotational symmetric parts are preferred.Reduce dimension of precise features."
"Ditching a connector could be fine, but applauding to a proprietary connector and proprietary wireless chip (which won't work with older apple products), is the critical part.That's not a user friendly decision, the main reason is a lock in effect. So it's not "courage" to ditch a working standard connector, it's a business decision. (I'm not even talking about the possibility of DRM-audio.)Further with the saturation in the smartphone market, it's much more difficult to change standards (3.5 and Bluetooth Low Energy) compared with a emerging market segment."
"As far as looking at the mechanisms in the video, all shear parts could be omitted and only bending hinges used at the corners of the solid structures, with the same functional output. So in my opinion the advantage is a stability one because of no stress concentration within the corners of a mechanical hinge (it would be distributed within the shear structures). What are further advantages? Or more precisely, what is the advantage compared to standard "compliant mechanisms" ( e.g. https://compliantmechanisms.byu.edu/content/intro-compliant-mechanisms )?"
"Another option to increase space efficiency would be to make the cabinet drawers accessible from both sides -for example for "island" style work environments- and place the pivots on opposite corners. Then the space usage increases from 78.5 % to 89.3 % with square base area.Other option would be one big one and an additional drawer which only uses the dead space in the corner (with pivot on opposite corner). Then it could also open to the side or opposite."
