Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If wireless access points operate in close proximity, then network coverage area increases, but interference between access points increases and performance degrades

Engineering Contradiction:

Improvenetwork coverage areaVSAvoidinterference between access points

Core Design Contradiction:

Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent changes operational parameters of wireless access points dynamically based on environmental conditions. Each access point monitors its wireless environment and adjusts configuration parameters (such as transmit power, channel selection, antenna patterns) to optimize performance while minimizing interference to and from neighboring access points, thereby maintaining network coverage while reducing harmful interference effects

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback mechanisms where wireless access points continuously monitor their operational environment and performance metrics. This feedback information is used to dynamically adjust configuration parameters, allowing the system to adapt to changing conditions and maintain optimal performance in dense deployments without significant interference degradation

Inventive Principle:

Principle #23Feedback

2Object-generated harmful factors

If wireless access points use coordinated configuration, then interference is reduced, but system complexity increases

Engineering Contradiction:

Improveinterference between access pointsVSAvoidsystem complexity

Core Design Contradiction:

Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent enables wireless access points to autonomously monitor their own operational environments and self-adjust their configuration parameters without requiring complex centralized coordination. Each access point independently makes decisions about its own configuration based on local measurements and pre-established rules, significantly reducing system complexity while still achieving interference reduction through coordinated-like behavior

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent divides the wireless network into independent autonomous segments, where each access point operates as an independent decision-making unit. This segmentation allows each node to manage its own configuration without requiring global system coordination, reducing overall system complexity while maintaining the ability to coordinate configurations locally to minimize interference

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If legacy wireless stations are supported, then compatibility is maintained, but network performance improvement is limited

Engineering Contradiction:

Improvelegacy station compatibilityVSAvoidnetwork performance

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent creates a universal system where wireless access points can serve multiple types of stations simultaneously - both legacy wireless stations and modern wireless stations. The access points adapt their configuration and communication methods to accommodate different station types, maintaining broad compatibility while optimizing performance for each device category through parameter adjustments

Inventive Principle:

Principle #6Universality (Multi-functionality)
