<br />
The design principle idea here: <br> <br />
'''Refrain from tight tolerances and press fits altogether.''' <br><br />
All parts need to feature plenty of tolerance such that <br><br />
nothing accidentally holds together due to friction (macroscale) <br><br />
or commensurate interdigitation energy barriers (nanoscale). <br><br />
<br />
'''This is meant to be applied in conjunction with: [[Post-tenstioning after pre-assembly]]''' <br><br />
More econvretely here in [[ReChain]] context: [[Rebar chain tensioning]] <br><br />
<br />
'''When assemblies are getting tensioned up in a later step''' <br><br />
then some '''parts assume exact positions through [[self centering]] structures'''. <br><br />
<br />
This especially holds for [[ReChain hull segment]]s <br><br />
For [[ReChain core Chain]]s self centering may not be needed as <br><br />
things only attach to the hull segments outside for positional reference. <br><br />
<br />
At macroscale this can lead to problems like: [[ReChain fall out disassembly]] <br><br />
[[ReChain assembly helper cliplocks]] can help.<br />
<br />
= Naming =<br />
<br />
A more general name here could be: [[PlentyClearanceAssembly]]<br />
<br />
== Macroscale ==<br />
<br />
The term "falling" only matches macro-scale physics well, <br><br />
where falling in is the thing happening when there is plenty of clearance and the end-effector lets go.<br />
<br />
== Nanoscale ==<br />
<br />
At the nanoscale things get less trivial due to [[vdW force]]s. <br><br />
One needs to design wit the with the resulting minimum energy state(s) in mind. <br><br />
Which of them are error sates and which of these error states are not self correcting and problematic. <br><br />
<br />
One likely gets intergigitating and sticking at commensurate surface corrugation notches. <br><br />
One might want to design for [[subperbubrisicty|superlubric]] non-commensurate interfaces <br><br />
and for [[vdW suck-in]] to just have just one single stable <br><br />
that is the desired assembly state (possible changed by tensioning tings up). <br><br />
