Solution Overview

Problem

Existing wireless power transmission systems face challenges in efficiently managing data communication during power transfer, particularly in maintaining stable data transmission while allowing for temporary pauses to accommodate urgent tasks or changes in power transfer conditions.

Innovation Solution

The wireless power transmitter sends pause information to the receiver, temporarily halting data stream transmission for a defined interval, enabling other tasks and improving data transport efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If data stream transmission continues without pause in wireless power transmission system, then data communication stability is maintained, but the system cannot accommodate urgent tasks or changes in power transfer conditions

Engineering Contradiction:

ImproveAbility to accommodate urgent tasksVSAvoidData communication stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements periodic pause intervals during data stream transmission, where the transmitter sends pause information at regular intervals to halt data transmission temporarily. This allows the system to periodically check for urgent tasks or power transfer condition changes while maintaining overall communication stability through structured resumption of data flow.

Inventive Principle:

Principle #19Periodic action

2Adaptability or versatility

If pause information is transmitted to halt data stream, then urgent tasks can be performed and power transfer conditions can change, but data transport efficiency decreases due to interruption

Engineering Contradiction:

ImproveAbility to perform urgent tasksVSAvoidData transport efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The transmitter sends pause information in advance before halting the data stream, allowing the receiver to prepare for the interruption. This preliminary notification minimizes the impact on data transport efficiency by enabling smooth transition and resumption, rather than abrupt termination and restart of data flow.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If continuous data stream transmission is maintained, then data transport efficiency is maximized, but the system lacks flexibility to handle changing power transfer conditions

Engineering Contradiction:

ImproveData transport efficiencyVSAvoidFlexibility to handle changing conditions

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts data stream transmission by incorporating pause intervals based on real-time power transfer conditions. The transmitter can adaptively introduce pauses when conditions change (such as power level adjustments or urgent tasks) and resume transmission when stable, creating a flexible yet efficient data transport mechanism.

Inventive Principle:

Principle #15Dynamics
