Solution Overview

Problem

Existing methods for device cross-region access are inefficient and prone to errors due to manual intervention and network limitations, leading to high inaccessibility and customer dissatisfaction during cross-region device testing.

Innovation Solution

Implement a distributed deployment of cross-region proxy servers to facilitate efficient and accurate cross-region access by determining the closest proxy server based on IP address information, using a target device's identification information, and setting access thresholds to prevent cross-region sales.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual modification of device tags is performed to enable cross-region access, then access capability is improved, but access efficiency deteriorates due to high workload and time consumption

Engineering Contradiction:

Improvecross-region access capabilityVSAvoidaccess efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system enables self-service by automatically determining the target proxy server based on the device's IP address information without requiring manual intervention. The target device autonomously completes the cross-region access process by receiving proxy server information from the source region server and establishing connection automatically, eliminating the need for manual tag modification while maintaining high adaptability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces a proxy server as an intermediary between the target device and the destination cloud server. The proxy server receives requests from devices in source regions, determines the appropriate target region server based on IP address, and forwards requests accordingly. This intermediary mechanism enables efficient cross-region access without manual intervention while maintaining regional access control policies.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If device tags are modified for testing purposes, then access flexibility is improved, but result credibility deteriorates due to customer perception of testing on different devices

Engineering Contradiction:

Improveaccess flexibilityVSAvoidtest result credibility

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Instead of modifying the actual device tag, the system creates a virtual copy of the access request through the proxy server. The proxy server replicates the device's access request with appropriate routing information based on IP address, allowing the device to access regional servers without physically modifying device identifiers. This maintains test result credibility while achieving access flexibility.

Inventive Principle:

Principle #26Copying

3Device complexity

If direct connection to distant cloud servers is attempted, then system simplicity is maintained, but access reliability deteriorates due to network delay and inaccessibility

Engineering Contradiction:

Improvesystem simplicityVSAvoidaccess reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The proxy server acts as an intermediary that improves access reliability by establishing local connections. Devices in source regions connect to the proxy server in their local region, which then communicates with target region servers. This two-hop approach maintains reasonable system complexity while significantly improving access reliability by avoiding direct long-distance connections and reducing network delay.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If regional access isolation is strictly enforced, then market order is maintained, but cross-region testing capability deteriorates

Engineering Contradiction:

Improveregional access controlVSAvoidcross-region testing capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts access control based on the device's location and testing requirements. The proxy server determines whether to allow cross-region access by evaluating the device's IP address and comparing it with the designated sales region. For legitimate testing scenarios, the system dynamically permits access to the appropriate regional server, while maintaining strict isolation for normal market operations. This dynamic approach preserves market order while enabling cross-region testing capability.

Inventive Principle:

Principle #15Dynamics
