Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless connection is implemented, then convenience and versatility of device connectivity is improved, but compatibility with traditional USB applications and devices deteriorates

Engineering Contradiction:

Improveconvenience of device connectivityVSAvoidcompatibility with traditional USB applications

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent creates a virtual USB interface that copies the behavior and appearance of a traditional wired USB connection. The wireless USB device mimics the enumeration procedure, device descriptors, and communication protocols of wired USB, making traditional USB applications perceive it as a standard USB device while actually communicating over wireless connections.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces a virtual USB interface layer as an intermediary between the wireless communication hardware and traditional USB applications. This virtual interface translates wireless communication protocols into USB-compatible protocols, mediating between the wireless connection and legacy USB software without requiring application modification.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If wireless USB connection is implemented, then versatility of USB technology is improved, but complexity of the system increases

Engineering Contradiction:

Improveversatility of USB technologyVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the wireless USB device universally compatible with multiple USB device types and applications by implementing a virtual USB interface that can emulate different USB device classes. This allows a single wireless USB implementation to serve storage, audio, video, and other USB functions without requiring separate implementations for each device type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If wireless connection is used, then convenience is improved, but reliability of USB connection deteriorates

Engineering Contradiction:

ImproveconvenienceVSAvoidconnection stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The virtual USB interface copies the connection management behavior of wired USB, including enumeration procedures, attach/detach operations, and device descriptor responses. This creates a reliable abstraction layer that presents consistent USB connection semantics to applications while handling wireless connection variations in the background.

Inventive Principle:

Principle #26Copying
