Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple frequency units are allocated to a single station, then throughput is improved, but allocation complexity increases

Engineering Contradiction:
ImprovethroughputVSAvoidallocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The frequency spectrum is segmented into multiple frequency units (FUs), each of which can be independently allocated to stations. This segmentation allows flexible allocation of multiple FUs to a single station to improve throughput, while the standardized segmentation structure helps manage allocation complexity through systematic resource division.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The allocation of frequency units is made dynamic and flexible, allowing the access point to allocate multiple FUs to stations based on real-time traffic conditions and station capabilities. This dynamic allocation optimizes throughput while managing complexity through adaptive decision-making rather than rigid fixed assignments.

Inventive Principle:
Principle #15Dynamics

2Loss of time

If multiple frequency units are allocated to a single station, then latency is reduced, but resource management complexity increases

Engineering Contradiction:
ImprovelatencyVSAvoidresource management complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

Frequency unit allocation information is prepared and communicated to stations in advance through allocation fields in control frames. This preliminary action allows stations to prepare for receiving multiple FUs, reducing processing latency while managing resource management complexity through pre-established allocation protocols.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The access point monitors station performance and traffic conditions, providing feedback to adjust frequency unit allocations dynamically. This feedback mechanism reduces latency by optimizing resource distribution in real-time while managing complexity through automated adaptive control based on measured performance metrics.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If frequency units are allocated through resource allocation fields, then allocation precision is improved, but field structure complexity increases

Engineering Contradiction:
Improveallocation precisionVSAvoidfield structure complexity
Core Design Contradiction:

Solution Approach 1:

The resource allocation information is segmented into structured fields within control frames, with each field representing specific allocation parameters. This segmentation provides precise control over frequency unit distribution while managing field structure complexity through modular, standardized field definitions that can be systematically processed.

Inventive Principle:
Principle #1Segmentation
