Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical connection to transmitter is used for software updates, then reliable data transfer is achieved, but device must be unpackaged or repackaged after update

Engineering Contradiction:

Improvedata transfer reliabilityVSAvoidpackaging operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical physical connection system (wires, ports) with an electromagnetic field-based wireless power transfer system. The transmitting element generates an electromagnetic field that couples with the receiving element in the packaged device, enabling both power and data transfer through the packaging barrier without mechanical contact or unpackaging operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless power transfer system serves multiple functions simultaneously: it transfers electrical power to charge the device battery and transfers data for software/firmware updates. This multi-functionality eliminates the need for separate operations and allows both power and data transfer to occur through the packaging barrier.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If known wireless data connections (WiFi, Bluetooth) are used, then wireless data transfer is achieved, but connection validation requires device access and transfer speed is insufficient

Engineering Contradiction:

Improvewireless connectionVSAvoiddata transfer speed

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent replaces conventional wireless communication protocols (WiFi, Bluetooth) with an inductive electromagnetic coupling system that operates like a wired connection but without physical contact. The transmitting element and receiving element create a coupled electromagnetic field that enables high-speed data transfer through the packaging barrier, eliminating the need for device access for connection validation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If inductive wireless power transfer is used for data transfer, then packaging barrier is penetrated, but power transfer efficiency must be maintained

Engineering Contradiction:
