A method and system for writing digital data to NFC chips in business cards that includes determining relevant data, testing for inactive chips, and using a projection apparatus for visual identification, along with a calibration system to associate wireless communication devices with corresponding chips, enabling flexible production and quick identification of inactive chips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated testing and visual identification systems are implemented, then identification speed and productivity improve, but device complexity increases

Engineering Contradiction:

Improveidentification speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary visual identification system (projection apparatus displaying codes or colors) that mediates between the testing device and the human operator. This intermediary translates complex testing results into simple visual signals, enabling fast automated testing without requiring complex interfaces or displays in the testing device itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service by having the business cards themselves display their status (active/inactive) through visual indicators projected onto them. The cards essentially identify their own status without requiring external complex diagnostic equipment, simplifying the overall system while maintaining high identification speed.

Inventive Principle:

Principle #25Self-service

2Device complexity

If manual inspection methods are used, then device complexity remains low, but identification time and productivity deteriorate

Engineering Contradiction:

Improvesystem simplicityVSAvoididentification time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical inspection with an automated electronic testing system combined with optical projection for visual feedback. The testing device automatically communicates with each NFC chip electronically, and the projection apparatus optically displays results, eliminating slow manual inspection while keeping the system relatively simple through the use of standard projection technology.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If recalibration is performed for each layout variation, then manufacturing precision is maintained, but productivity and adaptability deteriorate

Engineering Contradiction:

Improvepositioning accuracyVSAvoidreprint speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent implements preliminary action by pre-configuring the testing device with multiple layout profiles and coordinate systems. Before production begins, the appropriate layout profile is selected based on the business card arrangement, and the system automatically adjusts its testing sequence and visual identification display accordingly. This preliminary setup eliminates the need for time-consuming recalibration during production changes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system incorporates dynamic adaptability by allowing real-time selection and switching between different layout configurations. The testing device can dynamically adjust its operation parameters, testing sequence, and visual feedback display based on the selected layout, maintaining precision across different configurations without requiring physical recalibration.

Inventive Principle:

Principle #15Dynamics

4Reliability

If comprehensive testing of each chip is performed, then reliability improves, but productivity and time consumption worsen

Engineering Contradiction:

Improvedata writing successVSAvoidproduction speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent implements continuous useful action by performing testing operations in parallel across multiple chips simultaneously. The testing device can communicate with multiple NFC chips at the same time, and the visual identification system displays results for all tested chips continuously without interruption. This parallel continuous operation maintains high reliability through comprehensive testing while preserving production speed.

Inventive Principle:

Principle #20Continuity of useful action
