Abstract

Systems and methods are provided for designing a composite tool to manipulate a specific set of known fasteners in a product, the fastener(s) having a constrained access and specific torque requirements. The system comprises a display screen, a database, a means for scanning and a computing device executing at least an operating system configured to operate the display screen, the database and the means for scanning. The computing device is further configured to electronically select a virtual socket that is configured to properly engage the fastener at its driving end, virtually position at the fastener in a pre-secure and a post-secure position within a virtual constrained access, and electronically determine the existence of an interference condition at either or both of the pre-secure or post-secure position. When an interference condition exists, computing device electronically selects another socket with a different dimension and repeating the virtual positioning and electronically determine steps.

First claim

What is claimed is:

1. A computer implemented method for designing a composite tool to manipulate a specific known fastener in a product, the fastener having a constrained access and specific torque requirements, the method comprising:
electronically selecting a virtual socket with a first end and a second end that is configured to properly engage the fastener at a driving end of the fastener;
virtually positioning the fastener in a pre-secure and a post-secure position within a virtual constrained access;
electronically determining the existence of an interference condition at either or both of the pre-secure or post-secure position; and
when an interference condition exists, electronically selecting another socket with a different dimension and repeating the virtually positioning of the fastener and the electronically determining the existence of an interference.

2. The computer implemented method of claim 1 , further comprising determining the dimensions of the virtual constrained access.

3. The computer implemented method of claim 2 , wherein the determination of the dimensions of the virtual constrained access is made from one of information retrieved from a database and from a scanning means.

4. The computer implemented method of claim 3 , further comprising:
when an interference condition does not exist in regard to the virtual socket, selecting a virtual power tool to meet fastener torque specifications and that is configured to accept the virtual socket at the second end.

5. The computer implemented method of claim 4 , further comprising:
determining whether at any approach vector an interference condition does not exist between the selected virtual power tool and a component of the product when the power tool is virtually connected to the virtual socket at either the pre-secure position of the post-secure position.

6. The computer implemented method of claim 5 , wherein when an interference condition exists, selecting and adding a virtual socket extension between the second end of the virtual socket and the virtual power tool and determining whether at any approach angle an interference condition does not exist between any of the virtual socket, the virtual extension or the virtual power tool.

7. The computer implemented method of claim 5 , wherein the scanning means comprises one or more of an optical scanner, a laser scanner, a sonic scanner, a magnetic scanner, and an electromagnetic scanner.

8. The computer implemented method of claim 4 , wherein the scanning means is manipulated by a robot.

9. The computer implemented method of claim 5 , wherein the determination of whether at any approach vector an interference condition does not exist is accomplished by iteratively applying an actual tool to an actual product.

10. A system for designing a composite tool to manipulate a specific known fastener in a product, the fastener having a constrained access and specific torque requirements, comprising:
a display screen;
a database;
a means for scanning; and
a computing device executing at least an operating system configured to operate the display screen, the database and the means for scanning, the computing device being further configured to:
electronically select a virtual socket with a first end and a second end that is configured to properly engage the fastener at a driving end of the fastener;
virtually position the fastener in a pre-secure and a post-secure position within a virtual constrained access;
electronically determine the existence of an interference condition at either or both of the pre-secure or post-secure position; and
when an interference condition exists, electronically select another socket with a different dimension and repeat the virtually position of the fastener and electronically determine the existence of the interference.

11. The system of claim 10 , further comprising determining the dimensions of the virtual constrained access.

12. The system claim 11 , wherein the determination of the dimensions of the virtual constrained access is made from one of information retrieved from the database and from the scanning means.

13. The system of claim 12 , further comprising:
when an interference condition does not exist in regard to the virtual socket, the computing device is configured to select a virtual power tool to meet fastener torque specifications and that is configured to accept the virtual socket at the second end.

14. The system of claim 13 , further comprising:
determining whether at any approach vector an interference condition does not exist between the selected virtual power tool and a component of the product when the power tool is virtually connected to the virtual socket at either the pre-secure position of the post-secure position.

15. The system of claim 14 , wherein when an interference condition exists, selecting and adding a virtual socket extension between the second end of the virtual socket and the virtual power tool and determining whether at any approach angle an interference condition does not exist between any of the virtual socket, the virtual extension or the virtual power tool.

16. The system of claim 14 , wherein the scanning means comprises one or more of an optical scanner, a laser scanner, a sonic scanner, a magnetic scanner, and an electromagnetic scanner.

17. The system of claim 13 , wherein the scanning means is manipulated by a robot.

18. The system 14 , wherein the determination of whether at any approach vector an interference condition does not exist is accomplished by iteratively applying an actual tool to an actual product.
