Design failure mode effect analysis (DFMEA)
First Claim
1. A design failure mode effect analysis (DFMEA) method of analyzing faults and failures in the design of electronic apparatus and devices, wherein an information recording form including a data-entry mask is used for recording some information concerning the performed analysis and in which at least a portion of said recording form is displayed to a user in an electronic display format;
- the method comprising;
detecting and recording past design problems and corresponding solutions to the past design problems using said recording form;
associating keywords in a database to each said past design problems as individual functions;
associating data concerning each of said past design problems, in the same database, including information concerning past fails that occurred in similar applications;
detecting major changes and/or innovations, as well as any improved block or part of a new device with respect to other devices, thereby postulating possible new problems introduced by the new device; and
recording said new problems and possible solutions to said new problems using said recording form.

Abstract
A Design Failure Mode Effect Analysis (DFMEA) method analyzes faults and failures in the design phase of electronic devices. A data-entry mask is used for recording some information concerning the performed analysis and a portion of the recording form is displayed to a user in an electronic display format. The method detects and records past design problems and their corresponding solutions, by a DFMEA method using the data-entry mask form; associates keywords in a database with each problem; associates data concerning each of the design problems, in the same database, including information concerning past fails occurred in similar applications; detects major changes and/or innovations, as well as any improved block or part of a new device with respect to other devices, thereby postulating possible new problems introduced by the new device; and records the new problems and their possible solutions, by the DFMEA method and using the form.

4. A design failure mode effect analysis (DFMEA) method for analyzing failures in an initial design phase of electronic apparatuses and/or devices, the DFMEA method comprising:
-
recording in a data-entry mask some information concerning the analysis and wherein a portion of said data-entry mask is displayed to a user; detecting and recording, using said data-entry mask, past design problems and possible corresponding solutions; recording keywords in a database associating each of said past design problems to a corresponding keyword; associating data in the same database concerning each of said past design problems, including information concerning past failures that occurred in similar applications; detecting major changes and/or innovations of the electronic apparatuses and/or devices and defining new possible problems introduced by the electronic apparatuses and/or devices; and recording said new possible problems and possible solutions to said new possible problems using said data-entry mask. - View Dependent Claims (5, 6)
