Solution Overview

Problem

Current methods for monitoring mobile communications devices lack effective control and monitoring capabilities, leading to unauthorized use and excessive expenses, as users can move about and use devices in unauthorized ways.

Innovation Solution

A device management system where a master mobile device manages a slave mobile device through a slave manager module, controlling and monitoring user-accessible features such as cellular functions, messaging, and multimedia applications, with encryption for secure communication, allowing for setting usage limits and notifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users are given full access to mobile device features, then user freedom and device functionality are improved, but unauthorized use and excessive expenses occur

Engineering Contradiction:
Improveuser freedomVSAvoidunauthorized use
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent segments device access control by creating distinct manager modules (parental control manager, employee monitoring manager) that can selectively enable or disable specific features. This allows granular control over individual applications and functions rather than blanket restriction, maintaining user freedom for authorized activities while preventing unauthorized use through feature-level segmentation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces manager modules as intermediary components between the user and device features. These modules act as mediators that intercept and control access to device functions, allowing authorized users to operate normally while blocking unauthorized activities. The manager module serves as a buffer that enforces restrictions without completely eliminating user access to the device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If monitoring capabilities are enhanced to detect unauthorized use, then control and expense management are improved, but device complexity increases

Engineering Contradiction:
Improvecontrol capabilityVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements universal manager modules that can perform multiple functions across different device types and users. The same manager module architecture handles both parental control scenarios and employee monitoring scenarios, managing diverse features (messaging, browsing, applications) through a unified system. This multi-functionality reduces overall system complexity by avoiding the need for separate specialized monitoring systems for each use case.

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

Solution Approach 2:

The manager modules operate autonomously to enforce restrictions and monitor usage without requiring constant external intervention. The system automatically detects unauthorized activities, applies predefined policies, and generates reports without needing continuous manual configuration or oversight. This self-service capability reduces operational complexity while maintaining reliable control and monitoring functions.

Inventive Principle:
Principle #25Self-service

AI summary

A device management method, is disclosed in which available features on a slave mobile device (110) are managed (monitored or controlled) by a slave manager module (115) commanded by a master device (120) through secure messages exchanged between the two devices using respective two-way electronic messaging capabilities (130) on the two devices (110, 120). Selection of the features of the slave mobile device (110) to be controlled or monitored is facilitated on the master device (120) through a master manager module (125) resident thereon. The features that are controlled or monitored may comprise any user-accessible feature (112) incorporated or installed on the slave mobile device (110) and user access to the feature may be prevented according to at least one criterion, such as: date of use, time of day of use, number of times of use, originator and recipient. User access to the feature may be prevented access to the user-accessible feature when usage limitations for the feature have been reached.
