Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multi-cell scheduling is implemented to improve resource allocation efficiency, then productivity is improved, but device complexity increases due to multiple parameter configurations

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidparameter configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies universality by creating a common parameter configuration that can be applied across multiple cells simultaneously. The base station configures a unified parameter set that works for all scheduled cells, allowing the same configuration to serve multiple functions and cells, thereby improving resource allocation efficiency without proportionally increasing device complexity.

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

Solution Approach 2:

The patent segments the parameter configuration into two parts: common parameters that apply to all cells and cell-specific parameters that are individually configured. This segmentation allows the system to manage complexity by separating universal configurations from specific ones, enabling efficient multi-cell scheduling while maintaining manageable configuration overhead.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple parameter combinations are configured for each cell to improve signal transmission efficiency, then productivity is improved, but ease of operation deteriorates due to increased configuration management

Engineering Contradiction:
Improvesignal transmission efficiencyVSAvoidconfiguration management
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent uses universality by establishing a common parameter configuration that can be reused across multiple cells and scheduling scenarios. This common configuration serves multiple purposes and reduces the need for managing separate parameter sets for each cell, thereby improving signal transmission efficiency while simplifying configuration management.

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

Solution Approach 2:

The patent applies copying by allowing the common parameter configuration to be replicated and applied to multiple cells simultaneously. Instead of creating unique configurations for each cell, the system copies the validated common configuration across cells, ensuring consistent performance while reducing the operational burden of configuration management.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If individual parameter configurations are maintained for each cell to improve adaptability, then adaptability is improved, but device complexity increases due to multiple configuration sets

Engineering Contradiction:
Improvecell-specific configuration flexibilityVSAvoidconfiguration storage and management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments configuration parameters into common and cell-specific categories. The common parameters are configured once and applied universally, while cell-specific parameters are maintained separately for individual cells. This segmentation reduces overall device complexity by eliminating redundant common parameter storage while preserving necessary cell-specific adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by allowing different parameter configurations at different levels: common parameters provide uniform quality across all cells, while cell-specific parameters allow local customization where needed. This approach maintains adaptability for specific cells without requiring complete individual configuration sets for every cell.

Inventive Principle:
Principle #3Local quality
