Opportunity : A innovative stamping machine or device ...to punch a stamp in to
              a envolope 

Design specifications: Deriving from or on the lines of 

                       lemon or orange squasher (refer to devices used in the middle east)

                       .....that stamps (imprint or mark) on application of a lever 

                       viz. lever makes  application of pressure easy.


                       or ideally

                       a automated sensor based device ....that takes care of the
                       above on insertion of envolope or document


usages: Most public utility places , postal , courier or in most places where a acknowledgement
        seal or hall mark is required.

         

               
            
 Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      'http://uk.geocities.com/ravivenkatus/projects.pdf' ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
