Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic devices struggle with efficiently managing access levels for multiple users, particularly when transitioning between a primary user and a secondary user, often requiring complex authentication and limiting access for the secondary user without flexibility.

Innovation Solution

The electronic device transitions between modes based on predefined criteria, allowing a secondary user to access a subset of features while maintaining primary user control, using different authentication methods for each mode and requiring network connectivity, with options for immediate or delayed access configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electronic device implements multiple user modes with different access levels, then user access flexibility is improved, but device complexity increases

Engineering Contradiction:

Improveuser access flexibilityVSAvoidaccess management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments access rights into distinct modes (first mode for primary user with full access, second mode for secondary user with restricted access). Each mode has predefined access levels to applications and features, allowing flexible user management without requiring complex real-time permission evaluations. The system maintains separate access control mechanisms for each mode, simplifying the overall complexity while enabling multiple user scenarios.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the electronic device uses different authentication methods for different modes, then security is improved, but ease of operation decreases

Engineering Contradiction:

ImprovesecurityVSAvoidauthentication convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements preliminary authentication configurations where authentication methods are predetermined for each mode. The system stores authentication credentials and methods in advance, allowing users to be pre-configured for specific access levels. This eliminates the need for complex real-time authentication decisions and reduces operational complexity while maintaining security through predefined secure access paths.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the electronic device restricts access to a subset of applications for secondary users, then security is improved, but adaptability worsens

Engineering Contradiction:

ImprovesecurityVSAvoidapplication access flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic mode switching that allows the system to adapt access restrictions based on the operational context. The second mode can be configured with different access levels to applications, and the system can transition between modes based on user needs. This dynamic configuration enables flexible security management where access restrictions can be adjusted without requiring complete system redesign, balancing security with adaptability.

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.
