Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional magnetic stripe or EMV chip is used in transaction cards, then the card structure remains simple and manufacturing is easy, but the display capabilities, transaction capabilities, and processing capabilities are limited

Engineering Contradiction:

Improvetransaction capabilitiesVSAvoidcard structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional components (display elements, sensors, processors, communication modules) into a single integrated transaction card device, enabling enhanced transaction capabilities while maintaining a unified card structure that can be manufactured using conventional card production techniques

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The transaction card is designed to perform multiple functions including displaying transaction information, processing payments, providing feedback to users, and communicating with various terminals, thereby increasing adaptability without requiring separate devices for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of information

If dynamic display components and additional processing units are added to enhance transaction card capabilities, then real-time data display and account management are improved, but the device complexity increases

Engineering Contradiction:

Improvereal-time data displayVSAvoidprocessing units

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The card incorporates dynamic display components that can update transaction information in real-time based on processing needs, allowing the information state to change dynamically while the physical structure remains stable and manageable

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces intermediary components such as microcontrollers and communication modules that facilitate data processing and display updates, acting as mediators between the EMV chip, display elements, and external terminals to manage complexity through modular architecture

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A system for securely updating an electronic transaction card held by an account holder with an additional account and/or account data is described. A dynamic transaction card may be securely updated with an additional account by using pre-stored shell data and/or inactive data, whereby the pre-stored shell data may be populated using data received from an issuer system and/or the inactive data may be activated via an activation signal received from a mobile device.
