Abstract

Exemplary embodiments relate to methods, mediums, and systems for associating information, including critical-to-quality (CTQ) information such as minimum or maximum part dimensions, with parts in a three-dimensional model of a product. The information may be identified by performing a failure mode effect analysis (FMEA) against the model. The information is stored with the model data (e.g., in the form of an annotation applied to a model feature corresponding to the part in question). The model data may be consulted by product lifecycle management (PLM) applications during various phases of the product's lifecycle. Among other possibilities, the information may be used to automatically generate regulatory compliance documentation, to ensure product quality standards are met during a manufacturing process, or to perform postproduction quality monitoring of the product.

First claim

The invention claimed is:

1. A method performed by a computer system having at least one processor and a memory, method comprising:
creating, using modeling logic executing on the processor, a three-dimensional model of a product, the three-dimensional model comprising a feature representing a part of the product, the three-dimensional model being represented by model data stored in a non-transitory storage medium;
identifying a quality characteristic for the feature by performing a failure mode effect analysis against the three-dimensional model, wherein the quality characteristic comprises one or more of: a minimum value for a parameter of the feature, a maximum value for the parameter of the feature, or a range of values for the parameter of the feature;
storing the quality characteristic as structured data in a data structure associated with the feature within the model data; and
retrieving the stored quality characteristic from within the model data during at least one post-design phase of a product lifecycle management process to perform a post-design phase action with respect to the product.

2. The method of claim 1 , further comprising:
processing the quality characteristic with an electronic device configured to perform the post-design phase action with respect to the product.

3. The method of claim 2 , wherein the post-design phase is a production phase, and processing the quality characteristic comprises exporting the quality characteristic to a manufacturer system configured to manufacture the product based on the model.

4. The method of claim 2 , wherein the post-design phase is a compliance phase, and processing the quality characteristic comprises automatically generating a regulatory compliance document based on the quality characteristic.

5. The method of claim 2 , wherein the post-design phase is a postproduction monitoring phase, and processing the quality characteristic comprises:
receiving a report of a nonconformance relating to the product;
determining that the nonconformance is associated with the quality characteristic of the feature; and
performing at least one of adjusting the quality characteristic, associating the nonconformance with an entity responsible for designing the feature, or generating documentation of the nonconformance and transmitting the generated documentation to an organizational entity responsible for quality control of the product.

6. The method of claim 1 , wherein the data structure associated with the feature comprises an annotation applied to the feature on the model.

7. The method of claim 1 , wherein the post-design phase is a production phase and the post-design phase action comprises tool selection.

8. The method of claim 1 , wherein the post-design phase is a production phase and the post-design phase action comprises inspection.

9. One or more non-transitory computer-readable media storing instructions that, when executed, cause one or more processors to:
create, using modeling logic executing on a processor, a three-dimensional model of a product, the three-dimensional model comprising a feature representing a part of the product, the three-dimensional model being represented by model data stored in a non-transitory storage medium;
identify a quality characteristic for the feature by performing a failure mode effect analysis against the three-dimensional model, wherein the quality characteristic comprises one or more of: a minimum value for a parameter of the feature, a maximum value for the parameter of the feature, or a range of values for the parameter of the feature;
store the quality characteristic as structured data in a data structure associated with the feature within the model data; and
retrieve the stored quality characteristic from within the model data during at least one post-design phase of a product lifecycle management process to perform a post-design phase action with respect to the product.

10. The media of claim 9 , wherein the instructions further cause the one or more processors to:
process the quality characteristic with an electronic device configured to perform the post-design phase action with respect to the product.

11. The media of claim 10 , wherein the post-design phase is a production phase, and processing the quality characteristic comprises exporting the quality characteristic to a manufacturer system configured to manufacture the product based on the model.

12. The media of claim 10 , wherein the post-design phase is a compliance phase, and processing the quality characteristic comprises automatically generating a regulatory compliance document based on the quality characteristic.

13. The media of claim 10 , wherein the post-design phase is a postproduction monitoring phase, and processing the quality characteristic comprises:
receiving a report of a nonconformance relating to the product;
determining that the nonconformance is associated with the quality characteristic of the feature; and
performing at least one of adjusting the quality characteristic, associating the nonconformance with an entity responsible for designing the feature, or generating documentation of the nonconformance and transmitting the generated documentation to an organizational entity responsible for quality control of the product.

14. The media of claim 9 , wherein the data structure associated with the feature comprises an annotation applied to the feature on the model.

15. The media of claim 9 , wherein the post-design phase is a production phase and the post-design phase action comprises tool selection.

16. The media of claim 9 , wherein the post-design phase is a production phase and the post-design phase action comprises inspection.

17. A system comprising:
one or more computer processors;
one or more non-transitory computer-readable media storing instructions that, when executed, cause the one or more processors to:
create, using modeling logic executing on a processor, a three-dimensional model of a product, the three-dimensional model comprising a feature representing a part of the product, the three-dimensional model being represented by model data stored in a non-transitory storage medium;
identify a quality characteristic for the feature by performing a failure mode effect analysis against the three-dimensional model, wherein the quality characteristic comprises one or more of: a minimum value for a parameter of the feature, a maximum value for the parameter of the feature, or a range of values for the parameter of the feature;
store the quality characteristic as structured data in a data structure associated with the feature within the model data; and
retrieve the stored quality characteristic from within the model data during at least one post-design phase of a product lifecycle management process to perform a post-design phase action with respect to the product; and

an electronic device configured to process the quality characteristic to perform the post-design phase action with respect to the product.

18. The system of claim 17 , wherein the post-design phase is a production phase, and processing the quality characteristic comprises exporting the quality characteristic to a manufacturer system configured to manufacture the product based on the model.

19. The system of claim 17 , wherein the post-design phase is a compliance phase, and processing the quality characteristic comprises automatically generating a regulatory compliance document based on the quality characteristic.

20. The media of claim 17 , wherein the
