Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If SIM card method is used to transfer address book information, then transfer can be achieved, but the process becomes cumbersome and error-prone

Engineering Contradiction:

Improveease of address book transferVSAvoidcomplexity of transfer process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the address book data from the SIM card dependency and transfers it directly between mobile terminals using Bluetooth wireless communication. This separates the transfer mechanism from the SIM card, eliminating the need for physical SIM card installation and manual encoding operations, thus simplifying the overall transfer process while maintaining data transfer capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces Bluetooth wireless communication as an intermediary medium to facilitate address book transfer between mobile terminals. This intermediary replaces the traditional SIM card-based direct connection method, enabling seamless wireless data exchange without requiring physical card manipulation or complex encoding procedures

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional encoding and transmission method is used, then contact information can be transferred, but the encoding and transmission process becomes complicated

Engineering Contradiction:

Improveaccuracy of contact information transferVSAvoidcomplexity of encoding and transmission

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical encoding and transmission process with automated Bluetooth wireless communication. The system automatically handles the encoding, packaging, and transmission of address book data in standard formats (vCard, vBulletin), eliminating the need for users to manually encode information and reducing transmission errors while maintaining data accuracy

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
