Solution Overview

Problem

Existing multi-card terminal devices independently perform task processing, leading to inefficient use of shared hardware resources and increased power consumption due to similar data requirements among SIM cards.

Innovation Solution

The terminal device transmits a message carrying collaborative operation related information to the network device, negotiating with it to perform tasks using multiple SIM cards in a collaborative manner, reducing unnecessary communication and conserving power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If each SIM card performs task processing independently, then each logical terminal device can operate autonomously, but hardware resources are inefficiently used and energy consumption increases

Engineering Contradiction:

Improveautonomous operation of logical terminal devicesVSAvoidenergy consumption of terminal device

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent merges task processing operations across multiple SIM cards by introducing a master-slave relationship where slave SIM cards share task results with the master SIM card. This allows multiple logical terminal devices to operate autonomously while sharing hardware resources efficiently, reducing redundant computations and lowering energy consumption.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of operation

If each SIM card performs task processing independently, then each logical terminal device can operate autonomously, but hardware resources are inefficiently used

Engineering Contradiction:

Improveautonomous operation of logical terminal devicesVSAvoidhardware resource utilization efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The master SIM card serves multiple functions by processing tasks independently and also serving as a shared resource for slave SIM cards. This multi-functionality allows the master SIM card to handle both its own tasks and assist slave SIM cards, improving overall hardware resource utilization while maintaining autonomous operation of each logical terminal device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple SIM cards perform tasks independently, then each SIM card maintains operational independence, but communication overhead with network device increases

Engineering Contradiction:

Improveoperational independence of SIM cardsVSAvoidcommunication energy consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent merges communication operations by allowing slave SIM cards to share task processing results with the master SIM card instead of independently communicating with the network device for each task. This reduces the number of separate communication sessions required, lowering communication overhead and energy consumption while preserving operational independence through the master-slave architecture.

Inventive Principle:

Principle #5Merging (Combining)
