VSEngineering Contradiction Analysis

1Loss of energy

If parameters for wireless power supply are set using conventional methods, then power supply efficiency is improved, but communication throughput of user data decreases

Engineering Contradiction:
Improvepower supply efficiencyVSAvoidcommunication throughput
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent segments the parameter setting process into multiple sectors, where each sector corresponds to a specific direction or spatial region. By dividing the overall parameter configuration into sector-specific segments, the system can optimize power supply parameters for each direction independently without blocking communication channels, thus maintaining communication throughput while improving power supply efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic parameter adjustment based on spatial position and communication conditions. The system continuously adapts power supply parameters according to the current sector and communication state, allowing simultaneous optimization of power transfer and communication without static constraints that would reduce throughput.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If directional wireless communication and power supply are performed simultaneously, then system versatility is improved, but parameter setting complexity increases

Engineering Contradiction:
Improvesystem functionalityVSAvoidparameter setting complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a unified sector management framework that handles both communication and power supply functions through a common parameter set. The sector management unit stores IDs that indicate both communication parameters and power supply parameters, allowing a single mechanism to control multiple functions simultaneously, thereby reducing overall system complexity despite enhanced versatility.

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

Solution Approach 2:

The patent introduces an intermediary sector management unit that acts as a mediator between communication and power supply functions. This unit stores and manages sector IDs that coordinate both functions, simplifying the control architecture by centralizing parameter management rather than requiring separate complex control systems for each function.

Inventive Principle:
Principle #24Intermediary (Mediator)
