Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If detailed event tracking is implemented using RFID tags, then the amount of information and understanding about customer events is improved, but the storage requirements and infrastructure complexity increase significantly

Engineering Contradiction:

Improveevent data completenessVSAvoiddata volume

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential information needed for event tracking by using a bit window technique. Instead of storing complete event details, the system stores a simplified bit representation where each bit indicates whether a specific event type occurred. This extraction approach maintains the core analytical value while dramatically reducing data volume.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms detailed event data into a simplified parameter representation using bit windows. Each bit window represents a specific event type and uses binary states (0 or 1) to indicate occurrence. This parameter transformation converts complex event data into a compact format that preserves analytical utility while minimizing storage requirements.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If traditional RFID communication protocols are used with handshake procedures, then data accuracy is maintained, but communication time and system complexity increase

Engineering Contradiction:

Improvedata write accuracyVSAvoidcommunication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-configuring the RFID tag memory with bit windows and predetermined write command structures. The interrogator system pre-establishes communication protocols and error checking mechanisms, allowing for faster execution during actual data writing operations without compromising accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent skips unnecessary communication steps by implementing direct write commands that bypass traditional handshake procedures. The system rushes through the communication process by sending consolidated write commands that directly modify the bit windows without requiring extensive verification cycles, thereby reducing communication time while maintaining data integrity.

Inventive Principle:

Principle #21Skipping (Rushing through)

AI summary

A method for tracking events using a radio frequency identification (RFID) tag may include reserving a bit window in a memory on a radio frequency identification (RFID) tag, the bit window having multiple bits, randomly marking one of the bits in the bit window each time a RFID event occurs, counting a number of marked bits in the bit window, and determining a number of the RFID events using the counted number of the marked bits and a size of the bit window.
