Solution Overview

Problem

Computing devices often face productivity issues due to distractions from multiple applications and interruptions, particularly when guest or temporary users have unfettered access, leading to decreased focus and progress on specific tasks.

Innovation Solution

Implementing an application lock feature that restricts a guest user from exiting or switching applications, requiring user credentials or a predetermined gesture to unlock, while maintaining other functionalities, allowing the main user to control access and limit distractions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If guest or temporary users are given unfettered access to all applications, then ease of operation is improved, but productivity deteriorates due to distractions and interruptions

Engineering Contradiction:
Improveuser accessVSAvoidfocus and task completion
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system segments user access rights by creating distinct access levels: main users have full access to all applications, while guest users are restricted to specific applications only. This segmentation resolves the contradiction by allowing easy access for guests within their limited scope while preventing distractions from other applications, thereby improving productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by providing different access qualities to different users. Guest users receive limited access quality (restricted to specific applications) while main users receive full access quality. This localized differentiation enables guests to operate easily within their permitted scope without the distraction of other applications, resolving the productivity issue.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If multiple applications are available for diverse tasks, then adaptability is improved, but productivity deteriorates due to constant interruptions and distractions

Engineering Contradiction:
Improveapplication availabilityVSAvoidfocus and task completion
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system segments application availability by organizing applications into different accessible groups. Guest users can access only specific designated applications while being blocked from others. This segmentation maintains adaptability for the intended tasks while eliminating interruptions from unrelated applications, thereby improving productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts potentially distracting applications from the guest user's accessible environment. By removing irrelevant applications from the guest's view and access list, the system maintains necessary adaptability for permitted tasks while eliminating sources of distraction, thus improving productivity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If application locking restricts guest user access, then productivity is improved by reducing distractions, but device complexity increases

Engineering Contradiction:
Improvefocus and task completionVSAvoidaccess control mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The access control mechanism is implemented as a universal multi-functional system that handles multiple scenarios: restricting guests to specific applications, preventing access to certain applications, and maintaining seamless operation for main users. This universal approach improves productivity through consistent restriction enforcement while managing device complexity through a unified implementation strategy.

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

AI summary

A computer-implemented method entails steps of receiving user input signifying that an application on a computing device is to be locked and, in response to the user input, locking a user within the application to thereby permit the user to utilize functionalities of the application without exiting from the application or switching to another application on the computing device.
