Solution Overview

Problem

Current computing devices face challenges in managing data persistence and policy management, particularly in balancing the need for user experience with the costs and complexities of persistent and non-persistent workspaces, where issues like DLL Hell, configuration failures, and virus persistence complicate data storage and security.

Innovation Solution

Implementing a semi-persistent desktop model with a computing device that includes both persistent and non-persistent layers, where data storage policies are determined by file system, user, or dynamically constructed rules, allowing granular control and segregation of data persistence based on user identity and application usage, using a layering engine and policy engine to direct data storage accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a persistent workspace is used to retain user information between sessions, then user experience is improved, but management costs increase due to application issues such as DLL hell and accidental configuration failures

Engineering Contradiction:
Improveuser experienceVSAvoidmanagement complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the workspace into persistent and non-persistent components, allowing selective retention of information. The profile manager identifies specific objects (files, registry keys, environment variables) that should be persisted while allowing other changes to be discarded, thus maintaining user experience while reducing management complexity and avoiding DLL hell issues.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different persistence qualities to different parts of the workspace. Instead of making the entire workspace persistent or non-persistent, the system applies persistence selectively to specific objects based on their importance and characteristics, allowing critical user data to be retained while temporary or potentially harmful changes are discarded.

Inventive Principle:
Principle #3Local quality

2Device complexity

If a non-persistent workspace is used to reduce operating costs, then management costs are reduced, but user experience deteriorates due to lack of persisting information

Engineering Contradiction:
Improvemanagement complexityVSAvoiduser experience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The workspace is segmented into persistent and non-persistent sections, allowing the system to maintain a non-persistent overall structure for cost efficiency while selectively persisting important user information to maintain experience quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Specific critical objects within the non-persistent workspace are given persistent quality through the profile manager, ensuring that essential user information is retained while the rest of the workspace remains non-persistent for cost efficiency.

Inventive Principle:
Principle #3Local quality

3Reliability

If a profile manager is used to protect specific information based on policies, then information security is improved, but performance deteriorates due to copying or streaming overhead

Engineering Contradiction:
Improveinformation protectionVSAvoidperformance
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent uses copying to create a profile layer that references original objects without immediately duplicating their content. The profile manager maintains references and metadata about protected objects, allowing efficient identification and protection of specific information without the performance penalty of continuous copying or streaming of all data.

Inventive Principle:
Principle #26Copying

4Device complexity

If layering is used to persist all information on top of a non-persistent workspace, then a common pool of workspaces is managed, but unwanted configuration changes, application corruption, and viruses persist across usage

Engineering Contradiction:
Improveworkspace managementVSAvoidworkspace security
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The layering model is segmented to distinguish between desired persistent information (user profiles, settings) and unwanted persistent changes (viruses, corruption). The profile manager selectively identifies and protects only the intended objects, allowing the system to benefit from layering's workspace management efficiency while preventing security issues from persisting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different persistence qualities are applied to different objects within the layered workspace. Critical profile objects are marked for protected persistence while other objects remain subject to standard non-persistent behavior, allowing security issues to be contained and discarded while maintaining useful persistent information.

Inventive Principle:
Principle #3Local quality

5Adaptability or versatility

If policy management is tightly coupled with specific applications and profiles, then application-specific persistence requirements are met, but system complexity increases due to multiple policy engines

Engineering Contradiction:
Improveapplication-specific persistenceVSAvoidpolicy management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal profile manager that handles persistence requirements for multiple applications and object types through a single system. Instead of requiring separate policy engines for each application, the profile manager provides a unified mechanism that can identify and protect objects across different applications and contexts, reducing overall system complexity while maintaining application-specific adaptability.

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

AI summary

A computing device includes a memory and at least one processor configured to cooperate with the memory. The processor is to boot the computing device, and direct generated data to data storage. The data storage includes at least one persistent layer and a non-persistent layer. The processor determines if the data is to be stored in the at least one persistent layer or the non-persistent layer based on a version of the operating system being used to boot the computing device.
