Patent ID: 8140284

Claim:
A system for analyzing mutilation defects so as to improve quality control of a production line, wherein the production line is configured to mass produce a part, the system comprising: a benchmark image of a mass produced part; a grid system, having a predetermined number of cells plotted onto the benchmark image; a computer processing unit having an interface for entering mutilation defects, wherein the interface is operable to associate the location of the detected mutilation defect to the corresponding cell plotted on the benchmark image; a database in communication with the computer processing unit, the database for storing the mutilation defects; a plotting circuit having a code, wherein the code includes a predetermined number of labels and each of the predetermined number of labels is different from the other, and wherein the plotting circuit is operable to count each occurrence of a mutilation defect in each of the predetermined number of cells so as to give a total count of mutilation defects detected in each of the predetermined number of cells, and wherein each of the predetermined number of labels is associated with a predetermined range of the total count of mutilation defects, and wherein the plotting circuit plots the benchmark image with each of the predetermined number of labels corresponding to the total count of mutilation defects detected within the each of the predetermined number of cells onto the grid system; a display for displaying the benchmark image of the vehicle having the code plotted thereon; and a root cause analysis circuit having a second list, the second list having a plurality of predetermined root causes, wherein each one of the plurality of predetermined causes is associated with a type of mutilation defect and the area of the vehicle body in which the mutilation defect was found, and wherein the root cause analysis circuit analyzes the label of a particular cell and the location of the labeled cell so as to provide one of the plurality of predetermined root causes from the second list for the occurrence of the mutilation defect of each of the cells.
