Solution Overview

Problem

Communication terminals face issues with multiple applications sharing the same storage region, leading to data interference and loss when each application has a different origin, as they overwrite information intended for other applications.

Innovation Solution

Implementing a system where each application uses a distinct storage region by setting unique in-terminal URLs for each application, ensuring that applications with different origins have separate local storage areas, preventing data interference and ensuring data integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple applications share the same storage region, then storage space is efficiently utilized, but data interference and loss occur when applications with different origins overwrite each other's information

Engineering Contradiction:

Improvestorage space utilizationVSAvoiddata integrity

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent divides the storage region into separate storage spaces for each application based on their origins. The storage management unit allocates distinct storage regions to applications with different origins, preventing data interference while efficiently utilizing available storage space. This segmentation resolves the contradiction by organizing storage hierarchically rather than sharing a single common space.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements different storage quality characteristics for different applications based on their origins. Each application receives storage space with properties tailored to its specific needs and origin characteristics, allowing optimal data integrity for each application while maintaining overall storage efficiency. This local differentiation resolves the contradiction by customizing storage attributes rather than applying uniform storage management.

Inventive Principle:

Principle #3Local quality

2Device complexity

If applications use the same storage region, then device complexity is reduced, but data conflicts and loss occur when applications overwrite information intended for other applications

Engineering Contradiction:

Improvestorage management complexityVSAvoiddata loss

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The storage management unit automatically segments storage space into application-specific regions based on origin identification. This automated segmentation reduces manual configuration complexity while preventing data loss through proper isolation. The system manages the complexity internally without requiring complex user-level storage management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The storage management unit acts as an intermediary between applications and the underlying storage system. It handles the complexity of storage allocation and isolation, presenting a simplified interface to applications while managing the detailed segmentation and protection mechanisms that prevent data loss. This intermediary layer resolves the contradiction by absorbing management complexity away from applications.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If applications with different origins share storage space, then storage efficiency is improved, but data consistency and reliability deteriorate due to overwriting conflicts

Engineering Contradiction:

Improvestorage efficiencyVSAvoiddata consistency

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments storage space into origin-specific regions while maintaining efficient utilization through centralized management. The storage management unit monitors and allocates space within each segment, ensuring high utilization rates while maintaining data consistency through proper isolation. This segmentation approach resolves the contradiction by organizing storage efficiently at the segment level rather than requiring monolithic shared space.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates equipotential storage conditions for applications with the same origin by providing them with equivalent access rights and storage characteristics. This ensures data consistency within origin groups while maintaining overall storage efficiency through unified management policies. The equipotential approach resolves the contradiction by standardizing storage conditions rather than allowing inconsistent shared access.

Inventive Principle:

Principle #12Equipotentiality

AI summary

A communication terminal includes an obtaining unit configured to obtain an application, a storage unit configured to store information including origins used within the communication terminal for each application obtained by the obtaining unit, and a setting unit configured to search, when the communication terminal obtains an application, whether information that includes an origin of the application is stored in the storage unit and to set, when the information that includes the origin is not stored, information that includes an origin used within the communication terminal in a manner such that the information that includes the origin used within the communication terminal is different from information that is stored in the storage unit and includes origin.
