Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If high-resolution models of all objects are generated and transmitted, then model accuracy is improved, but data transmission load and processing calculation load increase

Engineering Contradiction:
Improvemodel accuracyVSAvoiddata amount
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies local quality by differentiating model generation quality based on spatial location and importance. Critical regions (e.g., character models, interactive objects) are rendered with high resolution and detailed data, while non-critical regions (e.g., background scenery, distant objects) use lower resolution and simplified data representations. This selective quality assignment reduces overall data transmission load while maintaining accuracy where it matters most for user experience.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The virtual space is segmented into multiple regions with different importance levels. The system divides the scene into foreground/background, interactive/non-interactive, and near/far zones, applying different model generation strategies to each segment. This segmentation allows the system to optimize data transmission by sending high-detail models only for segmented regions that require them, rather than transmitting uniformly high-resolution data for the entire virtual space.

Inventive Principle:
Principle #1Segmentation

2Reliability

If detailed models of all objects are generated, then communication quality is improved, but processing calculation load increases

Engineering Contradiction:
Improvecommunication qualityVSAvoidprocessing calculation load
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts model generation parameters based on real-time conditions such as user position, interaction state, and network bandwidth availability. When a user approaches or interacts with an object, the system dynamically increases model detail for that specific object. When the user moves away or network conditions deteriorate, the system dynamically reduces model complexity. This dynamic adaptation maintains communication quality during critical interactions while reducing processing load during transitions or low-priority scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes key parameters of model generation including resolution, polygon count, texture detail, and animation complexity based on importance levels. For high-importance objects, parameters are set to maximum quality; for low-importance objects, parameters are reduced. This parameter adjustment strategy ensures that processing resources are concentrated on generating detailed models only where necessary for effective communication, rather than uniformly processing all objects at high quality.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If uniform high-quality model generation is applied to all parts, then overall accuracy is improved, but data transmission efficiency decreases

Engineering Contradiction:
Improveoverall accuracyVSAvoiddata transmission efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system implements local quality by assigning different accuracy levels to different parts of the virtual space based on their importance. Critical components such as character models, facial expressions, and interactive objects receive high-accuracy treatment with detailed geometry and textures. Non-critical components like background environments, static props, and distant objects use lower-accuracy representations. This localized quality differentiation maintains overall communication effectiveness while significantly improving data transmission efficiency compared to uniform high-quality generation.

Inventive Principle:
Principle #3Local quality
