Problem statement:  nozzle or gas refilling (connecting a gas stove to a cyclinder)
                    ...air filling into tyres at gas station etc.

                    ....ability to clamp the regulator to the nozzle or apperture
                        to see to it that both the connecting devices are air-tight
                        locked ...usually termed coupling

Opportunity : A innovative mechanical structure that can surround or can be fitted
              on such appertures or nozzles ...for intance deriving from how a
              rose bud ...and a flower ...such that application of pressure at the
              bottom or around origin's of petal from bud should result into the mechanical
              structure ...that flowers into which the lockable device can be socketed.
              
                                
 Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in

        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
