Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple smart cards are carried to handle different transactions, then transaction versatility is improved, but the space occupied and portability are worsened

Engineering Contradiction:
Improvetransaction versatilityVSAvoidspace occupied
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines multiple smart card functions into a single mobile communication device. The device includes a mobile communication module and a smart card module integrated together, allowing users to perform multiple transactions (telecom services, banking, identification) using one device instead of carrying multiple separate smart cards. This merging approach maintains transaction versatility while significantly reducing the space occupied.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If IC chip is removed and induction coil is cut to modify electronic purse, then ease of modification is improved, but reliability and operational success are worsened

Engineering Contradiction:
Improveease of modificationVSAvoidoperational success
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent segments the smart card module as a separate, self-contained component within the mobile communication device. The smart card module includes its own control unit, memory, and communication interface, independent from the mobile communication module. This segmentation allows the smart card functionality to be modified or replaced without affecting the core mobile communication functions, maintaining reliability while enabling easy modification.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a contactless communication interface as an intermediary between the smart card module and external readers. This contactless interface (using NFC or similar technology) eliminates the need for physical contact points and induction coils that require cutting and wiring modifications. The intermediary communication method maintains operational success while greatly simplifying modification processes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If additional IC chip is installed in existing mobile communication device, then functionality is improved, but device structure integrity and factory warranty are worsened

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice structure integrity
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent implements the smart card module as a nested component within the mobile communication device. The smart card module is housed in a dedicated slot or compartment within the device body, similar to how a SIM card is installed. This nesting approach allows additional functionality to be added without disrupting the overall device structure or requiring modifications to the device's internal configuration, thereby preserving factory warranty and structural integrity.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Ease of operation

If ID verification information is not notified in transaction processing, then ease of operation is improved, but security and personal information protection are worsened

Engineering Contradiction:
Improveease of operationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements automatic ID verification where the smart card module automatically provides identification information to the mobile communication module during transactions. The user simply needs to authorize the transaction, and the system automatically handles the security verification processes. This self-service approach maintains ease of operation while ensuring security through automated ID notification and verification with financial institutions or service providers.

Inventive Principle:
Principle #25Self-service

AI summary

A mobile communication device is disclosed. The disclosed mobile communication device performs corresponding identity (ID) and data verification processing on a server through a smart chip and comprises a wireless communication unit, a smart chip, and a processing unit. The smart chip is configured to store ID verification information. The processing unit is electrically connected to the smart chip and the wireless communication unit. When the processing unit runs a transaction procedure, the processing unit accesses the ID verification information from the smart chip. The processing unit also drives the wireless communication unit to send the ID verification information to the server and requests the server to perform an ID verification procedure, so as to determine whether the transaction procedure is valid. Additionally, when the transaction procedure is invalid, the processing unit cancels the transaction procedure.
