Electronic Feature Access Modes for Guest Privacy Control

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic devices lack efficient mechanisms for selectively allowing and restricting access to features by different users, particularly in scenarios where a first user wants to grant temporary or limited access to a second user, such as in a guest mode, without compromising security or privacy.

Innovation Solution

The electronic device allows a first user to configure a second mode that grants a second user access to a subset of features, optionally without authentication, while maintaining control over which features the second user can access, and includes mechanisms for authentication and permission management through associated devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a first user grants a second user access to the electronic device in a second mode, then the second user can access a subset of features (applications and documents), but access to private documents and full feature set is restricted

Engineering Contradiction:

Improveflexibility in feature access controlVSAvoidaccess control mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments access control into distinct modes (first mode for full access, second mode for limited access) and divides features into accessible and restricted subsets. This allows the system to manage different user scenarios without requiring a completely complex access control system for every possible case.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary mechanism where the first user configures access permissions in advance, and the system automatically enforces these permissions when the second user attempts to access features. This intermediary permission structure simplifies the interaction between users and the complex access control system.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the electronic device allows the second user to access features without authentication, then ease of use is improved, but security and privacy are compromised

Engineering Contradiction:

Improveease of use for second userVSAvoidsecurity and privacy protection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The first user performs preliminary action by configuring access permissions and selecting which features the second user can access before the second user actually uses the device. This advance configuration allows the second user to access permitted features without needing to provide authentication, while still maintaining security through pre-established permission boundaries.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the first user about which features are accessible to the second user, allowing the first user to review and adjust permissions as needed. This feedback mechanism ensures that ease of use for the second user does not compromise security, as the first user can control exactly what information is exposed.

Inventive Principle:

Principle #23Feedback

3Object-affected harmful factors

If the first user restricts access to certain features while in second mode, then privacy protection is improved, but the second user's access flexibility is reduced

Engineering Contradiction:

Improveprivacy protection for first userVSAvoidaccess flexibility for second user

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by allowing different levels of access to different features and documents. Instead of a uniform access restriction, the system enables the first user to selectively grant access to specific features (e.g., certain applications or public documents) while restricting access to private documents and other sensitive features, thus balancing privacy protection with necessary access flexibility.

Inventive Principle:

Principle #3Local quality

4Reliability

If the electronic device maintains control over features even when first user is not present, then security is improved, but device complexity increases

Engineering Contradiction:

Improvesecurity controlVSAvoidaccess control system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically enforcing access control decisions based on pre-configured permissions. When the second user attempts to access a restricted feature, the system automatically denies access without requiring intervention from the first user. This automatic enforcement maintains security control while reducing the operational complexity of managing access during the first user's absence.

Inventive Principle:

Principle #25Self-service

AI summary

A first user of an electronic device operates the electronic device in a first mode with access to a plurality of features. The first user optionally configures the electronic device to provide permission for another user to use the electronic device in a second mode with access to a subset of the plurality of features. The first user optionally uses another electronic device to update the permissions to use the electronic device in the second mode while another user is using the electronic device.
