Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate receive units are used for wireless power transfer, then power transfer capability is achieved, but device complexity and cost increase

Engineering Contradiction:

Improvepower transfer capabilityVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the wireless power receiver functionality directly into the device itself, merging previously separate components (transmit unit, receive unit, and device) into an integrated system where the device contains both power transmission and reception capabilities, eliminating the need for external receive units

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device is designed with multi-functionality, serving both as a powered device and a wireless power receiver, allowing it to operate independently without requiring separate receive units, thereby simplifying the overall system structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If different control channel protocols are used by various vendors, then vendor-specific optimization is achieved, but compatibility between different wireless power products deteriorates

Engineering Contradiction:

Improvevendor-specific optimizationVSAvoidcompatibility

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The wireless power system is designed with universal compatibility, enabling it to work with multiple control channel protocols (Bluetooth, Wi-Fi, Zigbee, NFC) simultaneously, allowing the same system to interface with different vendor products regardless of their specific protocol choices

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adapts to different control channel protocols based on what is available in the communication environment, automatically selecting and switching between protocols to maintain compatibility and optimal performance across different vendor platforms

Inventive Principle:

Principle #15Dynamics

3Loss of energy

If inductive coupling is used for energy transfer, then power transfer efficiency is improved, but thermal issues and magnetic alignment requirements worsen

Engineering Contradiction:

Improvepower transfer efficiencyVSAvoidthermal issues

Core Design Contradiction:

Loss of energyVSTemperature

Solution Approach 1:

The system uses resonant oscillation at specific frequencies to enable periodic energy transfer through the coupling medium, allowing energy to be transferred efficiently while the resonant nature of the periodic action reduces continuous thermal buildup and improves overall transfer efficiency

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent introduces a coupling medium (such as water or biological tissue) that acts as an intermediary to transfer energy wirelessly through the body or between devices, enabling energy transfer without direct magnetic field coupling and thereby reducing thermal issues and alignment requirements

Inventive Principle:

Principle #24Intermediary (Mediator)
