Solution Overview

Problem

Current methods for searching computer-aided design (CAD) data, such as two-dimensional engineering drawings and three-dimensional models, are time-consuming and prone to errors as they require manual visual searching for specific dimensions and annotations.

Innovation Solution

A method and system that allow users to select and search for CAD metadata, such as dimensions and annotations, using a user interface with input mechanisms to specify search parameters, enabling an electronic processor to automatically identify and provide matching metadata within CAD data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual visual searching is used to locate CAD metadata, then the user can find dimensions and annotations, but the process is time-consuming and prone to errors

Engineering Contradiction:
Improveaccuracy of locating CAD metadataVSAvoidtime required to locate CAD metadata
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the manual visual searching mechanism with an automated electronic search system. The processor automatically searches through CAD data files for metadata matching user-specified parameters, eliminating the need for manual visual inspection and significantly reducing both time and error rates.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The search system allows users to define their own search criteria and parameters, and the system autonomously performs the search and returns results. The user inputs what they are looking for, and the system independently executes the search without requiring manual navigation through the CAD data.

Inventive Principle:
Principle #25Self-service

2Productivity

If automated search is implemented to locate CAD metadata, then searching time is reduced, but system complexity increases

Engineering Contradiction:
Improvespeed of locating CAD metadataVSAvoidcomplexity of search system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The search system is designed to handle multiple types of CAD metadata (dimensions, annotations, tolerances, surface finishes) through a single unified interface. The processor can search for various parameter types using the same basic search mechanism, reducing overall system complexity while maintaining high productivity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces an intermediary layer between the user and the CAD data - a search interface that translates user requests into processor-executable search parameters. This intermediary simplifies the interaction by providing a standardized way to specify search criteria without requiring users to understand the underlying data structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If comprehensive search parameters are collected from users, then search accuracy improves, but ease of operation decreases

Engineering Contradiction:
Improveprecision of search resultsVSAvoidease of using search function
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The search interface is segmented into distinct parameter categories (dimension parameters, annotation parameters, tolerance parameters, surface finish parameters). Users can select and specify only the parameters relevant to their search needs, rather than being required to fill out a comprehensive form for all possible parameter types.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows users to perform searches with partial parameter specifications. Users can search using only the most critical parameters for their needs, and the system will return results based on those partial criteria, rather than requiring complete specification of all possible parameters.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Methods and systems for searching computer-aided design (CAD) data. One method includes receiving a selection of a type of CAD metadata, displaying a user interface including at least one input mechanism for receiving a search parameter associated with the type of CAD metadata, and receiving the search parameter through the user interface. The method also includes, in response to receiving the search parameter, automatically identifying, with an electronic processor, CAD metadata associated with the CAD data matching the search parameter, and providing the CAD metadata matching the search parameter to a user.
