Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wireless power charging system is used in a vehicle, then contact terminals do not need to contact each other for charging, but it becomes difficult to stably support the portable electronic device when disposition changes frequently

Engineering Contradiction:
Improvewireless charging convenienceVSAvoidpower transmission stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The charging module is designed to be rotatable relative to the support module, allowing dynamic adjustment of the charging device's orientation and position to adapt to different portable electronic device dispositions while maintaining stable power transmission

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The wireless power transmitting apparatus is divided into separate support module and charging module, allowing independent positioning and rotation of the charging module to maintain optimal charging position regardless of device disposition changes

Inventive Principle:
Principle #1Segmentation

2Reliability

If the charging module is fixed in position, then power transmission is stable, but the device cannot adapt to different portable electronic device sizes and orientations

Engineering Contradiction:
Improvepower transmission stabilityVSAvoiddevice disposition flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The rotatable charging module enables dynamic repositioning to accommodate various device sizes and orientations while maintaining stable power transmission during charging operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The charging module can serve multiple positioning configurations through rotation, making it universally adaptable to different portable electronic device types, sizes, and orientations

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