Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual labeling is used, then the user can insert numeric labels, but the process is time-consuming and cumbersome

Engineering Contradiction:

Improvelabeling speedVSAvoidtime required for inserting numeric labels

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs automatic labeling by extracting references from the technical drawing file and sequentially inserting numeric labels without requiring manual user input for each label, enabling the system to serve itself in the labeling task

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical process of clicking and labeling with an automated computer-based system that uses software modules to extract references and insert labels automatically, eliminating the need for manual mechanical operations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If manual labeling is used, then the user can insert numeric labels, but precise control over labeling order cannot be achieved

Engineering Contradiction:

Improvelabeling order controlVSAvoidmanual labeling operation

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system performs preliminary extraction of all references from the technical drawing file before inserting labels, establishing a predetermined sequence based on reference positions and types, thereby ensuring precise control over labeling order before the actual labeling process begins

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses the extracted reference information as feedback to determine the sequential order of label insertion, adjusting the labeling sequence based on the spatial and hierarchical relationships detected in the drawing file

Inventive Principle:

Principle #23Feedback

3Productivity

If automatic labeling is implemented, then time is reduced, but system complexity increases

Engineering Contradiction:

Improvelabeling efficiencyVSAvoidsystem structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The automatic labeling system is divided into distinct functional modules: a reference extraction module that identifies and extracts reference elements from the technical drawing file, and a label insertion module that sequentially inserts numeric labels based on the extracted references, making the complex process manageable and modular

Inventive Principle:

Principle #1Segmentation
