Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If template matching with image processing adjustment is used to achieve precise work, then manufacturing precision is improved, but device complexity increases and ease of operation deteriorates

Engineering Contradiction:

Improveprecision of work on workpieceVSAvoidease of setting conditions

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The robot system automatically performs image processing and work area identification without requiring worker intervention for condition setting. The system self-adjusts parameters by capturing images, processing them through the processor, and automatically determining work area coordinates, thereby eliminating the need for workers to manually adjust image processing conditions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment operations with an automated image processing system. Instead of workers manually adjusting image processing parameters, the system uses a camera to capture images and a processor to automatically analyze and determine work area positions, substituting human操作 with automated computational processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If template matching with image processing adjustment is used to achieve precise work, then manufacturing precision is improved, but loss of time increases

Engineering Contradiction:

Improveprecision of work on workpieceVSAvoidtime for setting conditions

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system performs image capture and processing in advance before the actual work begins. By capturing images of the workpiece and processing them to determine work area coordinates prior to execution, the system prepares all necessary information beforehand, eliminating the need for time-consuming condition setting during the work process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The robot system automatically performs image processing and work area identification without requiring worker intervention for condition setting. The system self-adjusts parameters by capturing images, processing them through the processor, and automatically determining work area coordinates, thereby eliminating the need for workers to manually adjust image processing conditions.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If heavy load adjustment work is performed by workers for robot installation and work changes, then adaptability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveadaptability to work changesVSAvoidease of adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The robot system automatically performs image processing and work area identification without requiring worker intervention for condition setting. The system self-adjusts parameters by capturing images, processing them through the processor, and automatically determining work area coordinates, thereby eliminating the need for workers to manually adjust image processing conditions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system automatically adapts to different workpieces and work areas by changing processing parameters through image analysis. Instead of requiring manual reconfiguration, the system captures images of new workpieces, processes them to extract new coordinate information, and automatically adjusts its operation parameters to match the new work requirements.

Inventive Principle:

Principle #35Parameter changes
