Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wired charging method is used, then charging function is provided, but the image displayed on the charging surface is obstructed

Engineering Contradiction:

Improvecharging convenienceVSAvoidimage obstruction

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical wired charging system (adapters and USB lines) with a wireless electromagnetic field-based charging system using RFID technology. This substitution eliminates the physical obstruction caused by wired charging components while maintaining the charging function through electromagnetic energy transfer.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an RFID read/write module as an intermediary component that enables wireless communication and power transfer between the display and the portable device. This intermediary facilitates charging without direct physical contact, preventing image obstruction while ensuring reliable power delivery.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If RFID read/write module is added for wireless charging, then wireless charging function is provided, but device complexity increases

Engineering Contradiction:

Improvecharging convenienceVSAvoidmodule complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The RFID read/write module serves multiple functions simultaneously: it enables wireless power transfer, provides data communication, and facilitates device identification. By consolidating these functions into a single multi-functional module, the patent reduces overall system complexity compared to having separate components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the power transmission and data communication functions into a single RFID-based wireless charging system. This integration combines what would otherwise require separate hardware components into one unified module, simplifying the overall device architecture while providing comprehensive wireless charging capability.

Inventive Principle:

Principle #5Merging (Combining)
