Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If user-drawn line drawings and markers are used to create metaverse space, then user immersion and interaction are enhanced, but system complexity and processing requirements increase

Engineering Contradiction:

Improveuser immersionVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system pre-stores multiple graphic objects in a database before user interaction. When a user draws a line drawing or places a marker, the processor quickly matches it against the pre-stored objects to identify the corresponding graphic object, avoiding complex real-time generation and reducing processing complexity while maintaining high immersion

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses two-dimensional line drawings and markers as simplified copies or representations of three-dimensional graphic objects. These 2D inputs are processed and mapped to corresponding 3D objects in the metaverse space, reducing the complexity of direct 3D interaction while preserving user immersion through the copying relationship

Inventive Principle:

Principle #26Copying

2Measurement precision

If multiple graphic objects are pre-stored and matched based on line drawings and markers, then object identification accuracy improves, but processing time and computational resources increase

Engineering Contradiction:

Improveobject identification accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

Graphic objects are pre-stored in a database with their identifying features defined beforehand. The processor performs rapid matching by comparing user inputs against these pre-defined features, achieving accurate identification without extensive real-time computation, thus reducing processing time while maintaining high accuracy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system focuses processing on specific local features of line drawings and markers rather than analyzing entire images. By identifying key characteristic points and features locally, the system achieves accurate object identification with reduced computational overhead and faster processing

Inventive Principle:

Principle #3Local quality
