Abstract

The present invention is related to the repair of defective items where the defect symptom does not readily suggest the action to repair the item. Test and repair technicians isolate and repair defects. The defect symptom repair system provides a means for the technicians to pool their experience without extensive effort and to make their experience readily available. The defect symptom repair system is implemented as a web server on the Internet and easily accessible with use of web enabled devices. A defect symptom repair web server provides defect symptoms and associated repair actions. Each repair action has an effectiveness indicator. The defect symptom is match with the observed symptom. A repair action associated with the defect symptom is selected based on the effectiveness indicator. The repair action is applied to the item. The result, success or failure, is entered into the defect symptom repair web server and the effectiveness indicator of the repair action is computed including the most recent result. If the observed symptom does not match a defect symptom from the server, a defect symptom is created in the server. If a new repair action for a defect symptom is attempted, a repair action is added and the effectiveness indicator is calculated based on the result of the repair action attempt.

Claims

1. A defect symptom repair system comprising

a defect symptom repair server;

a client terminal, both connected by a network;

a defective item with a defect symptom;

where

the client terminal presents a first defect symptom description

the first defect symptom is matched with the defect symptom of the defective item

the client terminal presents an associated first repair action with a measure of effectiveness;

the first repair action is applied to the defective item;

the result, success or failure, of the first repair action to repair the defective item is entered at the client terminal;

the measure of effectiveness of the first repair action is computed to reflect the results of the application of the first repair action and updated in the defect symptom repair server.

2. The defect symptom repair system of claim 1, wherein a second defect symptom description is added to the defect symptom repair server

3. The defect symptom repair system of claim 1, wherein a second repair action with a measure of effectiveness of the second repair action is associated with the first defect symptom description and added to the defect symptom repair server

4. The defect symptom repair system of claim 1, wherein the first defect symptom description may be edited

5. The defect symptom repair system of claim 1, wherein the first repair action may be edited.

6. The defect symptom repair system of claim 1, wherein the network is the Internet and the client terminal is an Internet enabled device.

7. The defect symptom repair system of claim 1, wherein the first repair action effectiveness includes percent successful, number of times applied, date of most recent application.

8. The defect symptom repair system of claim 1 and a quality data collection system, wherein a first defect symptom datum is entered in the quality data collection system when the first defect symptom is selected.

9. The defect symptom repair system of claim 1 and a quality data collection system, wherein a first repair action datum is entered in the quality data collection system when the first repair action corrects the defect.

10. The defect symptom repair system of claim 1 and a part number family (a set of part numbers that have identical defect symptom descriptions and repair actions including the first defect symptom and first repair action) wherein part number family is related to the first defect symptom.

11. A method of repairing a defective item comprising

a defect symptom repair action database including

a first defect symptom description entry and

an associated first repair action with a measure of effectiveness entry

a means to access entries in the defect symptom repair action database

a defective item with a defect symptom where

the item defect symptom is matched with the first defect symptom

the first repair action is applied to the defective item

the effectiveness of the first repair action is computed including the success or failure of the first repair action to repair the defective item and updated in the database.

12. The method of repairing a defective item of claim 11, wherein a second defect symptom description entry is added to the defect symptom repair action database.

13. The method of repairing a defective item of claim 11, wherein a second repair action associated with the first defect symptom and a measure of effectiveness entry is added to the defect symptom repair action database.

14. The method of repairing a defective item of claim 11, wherein the network is the Internet and the means to access entries in the defect symptom repair action database is a web enabled device.

15. The method of repairing a defective item of claim 11 and a means to collect defect information, wherein information related to the first defect symptom is collected when the first defect symptom is selected and information related to the first repair action is collected after the first repair action is applied.

16. A defect symptom repair database,

a client terminal, both connected by a network,

a defective item with a defect symptom where the defect symptom repair database includes

a first defect symptom description and

an associated first repair action with an effectiveness indicator wherein

a. the client terminal displays the first defect symptom description

b. the first defect symptom is matched with the defect symptom of the item

c. the client terminal displays the first repair action with the effectiveness indicator

d. the first repair action is applied to the defective item

e. the effectiveness indicator for the first repair action is calculated including the result of applying the first repair action to the defective item and updated in the database.

17. The defect symptom repair database of claim 16, wherein a second defect symptom description is added to the defect symptom repair database.

18. The defect symptom repair database of claim 16, wherein a second repair action associated with the first defect symptom and an effectiveness indicator is added to the defect symptom repair database.

19. The defect symptom repair database of claim 16, wherein the network is the Internet and the client terminal is a web enabled device with a web browser.
