Solution Overview

Problem

Existing composite chip cards are vulnerable to data theft and fraudulent use due to their ability to be sensed by wireless signals, making it difficult to detect and control unauthorized access.

Innovation Solution

A composite chip card with a security protection interface that includes an induction coil, a chip module, and a security protection module, which can be either sensing-type or mechanical, to activate and control transactions based on user-specific conditions such as light, heat, resistance, or fingerprint verification, or mechanical activation, thereby enhancing security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If contactless RFID technology is integrated into chip cards to enable wireless communication and payment functions, then the functionality and convenience of the card are improved, but the card becomes vulnerable to remote copying and data theft by unauthorized readers

Engineering Contradiction:
Improvecontactless communication functionalityVSAvoidvulnerability to remote copying and data theft
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by incorporating a security protection interface with a mechanical structure that proactively prevents unauthorized reading. The mechanical lock engages with a corresponding mechanism in the reader, physically blocking the reading process before it can occur. This preemptive measure counteracts the harmful effect of remote copying by creating a mechanical barrier that unauthorized readers cannot overcome.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The security protection interface acts as an intermediary between the card and the reader. It includes a mechanical structure that mediates the communication process by requiring physical engagement to activate the contactless reading function. This intermediary mechanism ensures that only authorized readers with the corresponding mechanical key can initiate communication, thereby preventing unauthorized access while maintaining legitimate functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a security protection interface with mechanical structure is added to the chip card to prevent unauthorized access, then the security against remote copying is improved, but the device complexity increases

Engineering Contradiction:
Improvesecurity against remote copyingVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the security protection function with the existing contactless communication interface. The mechanical structure is integrated into the same interface assembly that handles RFID communication, combining security and communication functions in a unified structure. This merging approach reduces overall complexity compared to having separate security and communication systems, as the mechanical lock and reader engagement mechanism share the same physical and electrical interface.

Inventive Principle:
Principle #5Merging (Combining)
