per Derek:
How is it possible you are managing to jam a Carrick Component?
In my view, the use of the term 'carrick component' is an arbitrary one.
It is possible (ie I am not 100% certain) that you are attempting to draw an analogy between the core function of #1439 Carrick bend and yChan's presentation.
What you [possibly] observe as a 'carrick component' is (in my observation) a #206 crossing hitch (or crossing knot depending on perspective).
The core of #1439 Carrick bend (in my view) consists of 2
inter-linked crossing hitches.
In order for the 2 crossing hitches to remain linked and stable, there must be simultaneous
through loading from both SPart's. What is occurring is that the
continuation of each SPart traps and clamps the tail of the
opposite crossing hitch. The trapping and clamping of the tails is occurring simultaneously in a balancing act.
Further off-topic remarks:There is no functional 'nipping structure' in #1439 Carrick bend - because each crossing hitch is only loaded at one end. It is a balancing act of forces - where the tail of each crossing hitch is simultaneously trapped and clamped.
I also believe that a 'capstan effect' also plays a [lesser] role - in that, any potential slippage of a tail is
inhibited by the U turn of the tail around its own SPart.
Also, #1439 Carrick bend is a final energy stable state which results from a capsizing event inducing from a particular initial dressing state. Although, it is possible to tie the final energy stable form
directly, by inter-linking the 2 crossing hitches (which thereby avoids the capsizing event some knot tyers use to reach the final form).
