Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If clustering is performed based solely on access point locations and serving range, then device complexity is reduced, but communication efficiency and reliability deteriorate

Engineering Contradiction:
Improveclustering complexityVSAvoidcooperative transmission reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent changes the clustering parameters from static location-based metrics to dynamic channel condition-based metrics. Access points are clustered based on real-time channel quality indicators, signal strength, and interference levels, allowing the system to adapt to changing environmental conditions and maintain reliable cooperative transmission.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The clustering configuration is made dynamic rather than static. The system continuously monitors channel conditions and adjusts cluster formations in real-time, enabling access points to be reorganized based on current network conditions, which improves transmission reliability without increasing operational complexity.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If traditional wireless communication systems are used without radar sensing integration, then device complexity is lower, but security against eavesdroppers deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoideavesdropper interference
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent merges radar sensing functionality with wireless communication systems into an integrated platform. The same hardware infrastructure is used for both communication and radar-based security monitoring, allowing the system to detect eavesdroppers and adjust transmission parameters accordingly without proportionally increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The wireless communication units are designed to perform multiple functions: standard data transmission and radar-based security monitoring. This multi-functionality allows the system to maintain lower complexity while gaining enhanced security capabilities through the integrated radar sensing ability.

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

3Productivity

If more wireless communication units are deployed to improve connectivity, then communication efficiency improves, but interference and security risks increase

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by assigning different functional roles to different subsets of wireless communication units based on their local environment and radar-detected conditions. Some units are designated for radar sensing, others for communication, and the configuration is optimized locally for each unit's specific situation, reducing overall interference while maintaining high communication efficiency.

Inventive Principle:
Principle #3Local quality
