Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a network gateway is created between UWB and RFID systems to enable communication, then mutual knowledge between the two systems is improved, but the device complexity and deployment difficulty increase significantly

Engineering Contradiction:

Improvecommunication compatibilityVSAvoidgateway architecture complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses the graphic code as an intermediary element that bridges UWB and RFID systems. Instead of creating a complex network gateway, the graphic code contains RFID identifier information that can be read by UWB devices, enabling indirect communication between the two systems through a simple visual interface.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the complex mechanical/electrical gateway system with an optical information transfer mechanism. The RFID tag information is converted into a visual graphic code that can be captured and decoded by UWB devices, substituting physical network infrastructure with optical data transmission.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a network gateway is created to enable system communication, then mutual knowledge between systems is improved, but the ease of deployment deteriorates when objects transition between environments

Engineering Contradiction:

Improvesystem interoperabilityVSAvoiddeployment flexibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The graphic code serves as a portable intermediary that can be attached to objects and read by any UWB device in any environment. This eliminates the need for environment-specific gateway infrastructure, allowing seamless deployment across different locations and systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a visual copy of the RFID identifier information in the form of a graphic code. This copied information can be universally read and interpreted by UWB devices without requiring the original RFID system infrastructure, enabling environment-independent deployment.

Inventive Principle:

Principle #26Copying

3Adaptability or versatility

If two types of tags (RFID and graphic code) exist on the same object, then identification capabilities are improved, but the difficulty of discovery and pairing between the tags increases

Engineering Contradiction:

Improveidentification capabilityVSAvoidtag discovery difficulty

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent merges the identification functions of RFID and graphic code tags into a unified system where the graphic code contains and represents the RFID identifier. Instead of having two separate tags that need to be discovered independently, the information is combined into a single visual element that provides both identification functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces the need for radio frequency discovery mechanisms with optical reading. The UWB device can visually capture and decode the graphic code to discover the RFID identifier, substituting complex RF tag discovery with simpler optical recognition.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
