Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If frequency resources from multiple frequency bands are combined into subbands for integrated spectrum channel, then spectrum utilization flexibility and data transmission efficiency are improved, but system complexity and parameter management difficulty increase

Engineering Contradiction:

Improvespectrum utilization flexibilityVSAvoidparameter management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the integrated spectrum channel into multiple subbands, each with its own parameter set. This segmentation allows independent optimization of parameters for each subband while maintaining overall system flexibility. The transmitting device can apply different parameters to different subbands, enabling fine-grained spectrum utilization without managing all parameters centrally.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by allowing different parameter configurations for different subbands within the integrated spectrum channel. Each subband can have optimized parameters suited to its specific characteristics, while common parameters apply across all subbands. This resolves the contradiction by enabling localized optimization without requiring complete customization of every parameter in every subband.

Inventive Principle:

Principle #3Local quality

2Productivity

If a single transport block is generated for transmission across multiple subbands with both common and different parameters, then resource utilization efficiency is improved, but generation and management complexity increases

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoidtransport block generation complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the transmission across multiple subbands into a single transport block, consolidating what would otherwise require multiple separate transmission processes. This merging improves productivity by enabling efficient resource allocation and unified management across the integrated spectrum channel, while the hybrid parameter approach keeps generation complexity manageable.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs parameter changes by applying a hybrid parameter set - common parameters that remain unchanged across subbands and different parameters that vary by subband. This selective parameter application enables efficient single transport block generation across diverse subbands without requiring complete parameter customization, thus improving productivity while controlling complexity.

Inventive Principle:

Principle #35Parameter changes

3Quantity of substance

If multiple frequency bands are integrated into a single virtual cell, then spectrum resource utilization is enhanced, but channel management and coordination difficulty increases

Engineering Contradiction:

Improvespectrum resource availabilityVSAvoidchannel management ease

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent creates a single virtual cell that serves multiple frequency bands simultaneously, enabling universal management of heterogeneous spectrum resources. This multi-functional cell structure enhances spectrum resource availability while simplifying coordination through a unified management entity, resolving the contradiction between resource quantity and management ease.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The integrated spectrum channel acts as an intermediary layer between multiple frequency bands and the transmission system. This intermediary structure consolidates diverse frequency resources into a unified interface, enhancing available spectrum resources while simplifying channel management through standardized access and control mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)
