Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beamforming parameters are dynamically adjusted to adapt to changing radio frequency conditions, then communication link quality is improved, but memory resources are consumed faster due to frequent updates of phase and amplitude settings

Engineering Contradiction:

Improvecommunication link qualityVSAvoidmemory resource consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The memory is divided into two distinct portions: a first portion for storing current operational phase and amplitude settings, and a second portion for storing alternate phase and amplitude settings. This segmentation allows the system to maintain multiple beamforming configurations simultaneously without consuming excessive memory resources, as each portion can be optimized for its specific purpose.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system pre-calculates and stores multiple sets of phase and amplitude settings in advance, including alternate settings that can be quickly switched to when communication conditions change. This preliminary preparation eliminates the need for real-time calculation during link adjustments, reducing memory access time and allowing efficient use of stored configurations.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple sets of phase and amplitude settings are stored for different targets, then beamforming adaptability is improved, but memory size requirements increase

Engineering Contradiction:

Improvebeamforming adaptabilityVSAvoidmemory size

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The memory structure is designed to serve multiple functions: the first portion stores settings for current operational targets, while the second portion stores alternate settings that can be used for either alternative targets or refined settings for existing targets. This multi-functional design allows the same memory resources to support various beamforming scenarios without requiring separate dedicated storage for each possibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically allocates and updates the second portion of memory with alternate phase and amplitude settings based on current communication needs. Rather than statically pre-loading all possible settings, the system maintains a pool of alternate settings that can be dynamically refreshed and updated as new beamforming configurations are discovered or as communication conditions evolve.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the wireless node tests alternate beamforming settings to optimize communication, then link quality is improved, but time for testing and switching increases

Engineering Contradiction:

Improvelink qualityVSAvoidtesting and switching time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Multiple alternate phase and amplitude settings are pre-calculated and stored in the second portion of memory before actual communication optimization is needed. This allows the controller to quickly retrieve and test pre-prepared configurations rather than calculating new settings in real-time, significantly reducing the time required for beamforming optimization and switching between configurations.
