Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If electromagnetic signals are used for wireless power transmission, then power can be transmitted wirelessly, but power loss increases significantly over distance

Engineering Contradiction:

Improvewireless power transmission efficiencyVSAvoidpower loss over distance

Core Design Contradiction:

Use of energy by moving objectVSLoss of energy

Solution Approach 1:

The patent divides the wireless power transmission system into multiple antenna elements arranged in arrays at both transmitter and receiver ends. Each antenna element processes and transmits a portion of the total power signal, allowing the system to maintain efficiency over longer distances through distributed transmission and reception across multiple segmented components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from traditional linear or planar antenna arrangements to three-dimensional volumetric antenna arrays. This spatial dimensionality increase allows for more efficient beam forming and energy concentration in specific directions, reducing power loss by directing energy precisely toward the receiver rather than radiating in all directions.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Use of energy by moving object

If traditional wireless power methods are used, then power transmission can occur, but interference with electronic devices occurs

Engineering Contradiction:

Improvepower transmission capabilityVSAvoidinterference with electronic devices

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent employs beam forming techniques that concentrate power transmission energy into specific localized spatial regions rather than uniform omnidirectional radiation. By directing energy precisely where needed and maintaining low power levels in surrounding areas, the system achieves effective power transmission while minimizing interference with other electronic devices in the environment.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements feedback mechanisms where the receiver communicates with the transmitter about received power levels and environmental conditions. This feedback allows the transmitter to dynamically adjust beam directions, power levels, and antenna configurations to maintain efficient transmission while avoiding interference with sensitive electronic devices detected in the transmission path.

Inventive Principle:

Principle #23Feedback

3Reliability

If direct connection to power sources is required, then reliable power supply is achieved, but ease of operation decreases

Engineering Contradiction:

Improvepower supply reliabilityVSAvoidconnection convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical physical connections (plugs and sockets) with wireless electromagnetic field-based power transmission. This substitution eliminates the need for physical contact and connection maneuvers while maintaining reliable power transfer through controlled electromagnetic coupling between transmitter and receiver antenna arrays.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces electromagnetic fields as an intermediary medium to transfer power between source and device without direct physical connection. The field acts as a mediator that carries energy through space, enabling reliable power transmission while eliminating the operational complexity of plugging and unplugging physical connectors.

Inventive Principle:

Principle #24Intermediary (Mediator)
