Innovation Solution

The method involves establishing connections between antennas and SIMs across multiple terminals using local networks like Bluetooth or Wi-Fi, allowing terminals to share terminal information and determine optimal connections based on criteria such as operation speed and functionality, enabling seamless wireless communication by utilizing the subscription information stored in other terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If multiple terminals share SIM and RF modules to reduce cost, then device complexity and cost are reduced, but reliability and connection stability deteriorate

Engineering Contradiction:
Improveterminal complexityVSAvoidconnection stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system segments the connection management by introducing a master terminal that coordinates SIM-RF module connections among multiple terminals. Each terminal maintains its own SIM and RF module but shares connection management responsibilities with the master terminal, dividing the complexity while preserving individual terminal reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The master terminal acts as an intermediary that manages the connections between SIM modules and RF modules across multiple terminals. It receives connection requests, determines optimal connections based on terminal information, and coordinates the establishment of connections, thereby maintaining reliability while enabling resource sharing

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If terminals share SIM and RF modules across local networks, then ease of use and accessibility improve, but device complexity increases

Engineering Contradiction:
ImproveusabilityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables self-service by allowing terminals to automatically exchange terminal information via local networks (Bluetooth, Wi-Fi) and establish connections without manual intervention. The master terminal automatically determines optimal SIM-RF connections based on received terminal information, eliminating complex manual configuration while improving usability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The master terminal performs multiple functions including receiving terminal information from multiple terminals, determining optimal connection configurations, managing SIM-RF module connections, and coordinating communication across the terminal group, thereby simplifying the user interface while handling system complexity centrally

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If terminals establish connections based on terminal information exchange, then adaptability and versatility improve, but loss of time increases

Engineering Contradiction:
Improveconnection flexibilityVSAvoidconnection establishment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by having terminals proactively exchange terminal information via local networks before formal connection establishment. The master terminal analyzes received terminal information in advance and pre-determines optimal SIM-RF module connection configurations, reducing the time required during actual connection establishment while maintaining adaptability

Inventive Principle:
Principle #10Preliminary action
