Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual PIN code entry is required for SIM card verification, then security verification is performed, but user operation efficiency deteriorates and user experience worsens

Engineering Contradiction:

ImproveSIM card security verificationVSAvoidUser operation efficiency

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The terminal device automatically retrieves and verifies the SIM card PIN code through stored mapping relationships between ICCID and PIN codes, eliminating the need for manual user input. The system performs self-service verification by querying the mapping relationship and automatically completing the authentication process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The terminal device pre-stores the mapping relationship between ICCID and PIN code in advance. When SIM card verification is needed, the system quickly retrieves the pre-stored PIN code through the mapping relationship, avoiding real-time manual entry and significantly improving verification efficiency.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual PIN code entry is required, then verification function is implemented, but verification time increases and productivity decreases

Engineering Contradiction:

ImprovePIN code verification functionVSAvoidVerification speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The mapping relationship between ICCID and PIN code is established and stored in advance in the terminal device. During verification, the system directly queries this pre-stored mapping relationship to obtain the PIN code, eliminating the need for manual entry and significantly reducing verification time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal device automatically performs the entire verification process by querying the stored mapping relationship and submitting the PIN code to the SIM card for verification, eliminating manual intervention and improving verification throughput.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If automatic PIN code verification is implemented, then user efficiency improves, but device complexity increases due to mapping relationship storage

Engineering Contradiction:

ImproveAutomatic verification capabilityVSAvoidMapping relationship storage system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a mapping relationship table as an intermediary data structure that stores the correspondence between ICCID and PIN code. This intermediary layer enables automatic verification by allowing the terminal to query the PIN code through ICCID without requiring complex cryptographic operations or additional hardware components.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

This application provides a method and an apparatus for verifying a personal identification number PIN code. When a first SIM card is inserted into a powered-on terminal device or the terminal device into which the first SIM card is inserted is powered on, whether a mapping relationship includes a PIN code to which a first ICCID of the first SIM card is mapped is queried; the PIN code is sent to the first SIM card if the mapping relationship includes the PIN code to which the first ICCID is mapped; and a verification result of the PIN code from the first SIM card is received.
