Solution Overview

Problem

Current scheduling technologies for managing meetings and controlling access to electronic documents on mobile devices are inefficient, often bogged down by various inefficiencies, and lack effective control over information access and security.

Innovation Solution

A device management system that generates policy data for electronic documents, determining if client devices meet required hardware and software configuration attributes before allowing access, and enforcing access policies to ensure authorized access and secure data handling, including rendering information inaccessible when leaving a specified location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If current scheduling technologies are used to manage meetings and control access to electronic documents on mobile devices, then basic scheduling functions can be performed, but the system efficiency is poor and data security control is insufficient

Engineering Contradiction:
Improvesystem efficiencyVSAvoiddata security control
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary device qualification checks before allowing document access or download. The device management system evaluates hardware and software attributes of client devices in advance, and only devices meeting specified policies are granted access to electronic documents, preventing security issues before they occur

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

A device management system acts as an intermediary between users and electronic documents on mobile devices. This intermediary enforces access policies, manages device qualifications, and controls document access based on hardware and software attributes, improving both security and efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If access control policies are enforced to ensure data security, then unauthorized access is prevented, but the complexity of the system increases

Engineering Contradiction:
Improvedata security controlVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device management system automatically evaluates device qualifications and enforces access policies without requiring manual intervention. The system self-manages the complexity of policy enforcement, device assessment, and access control decisions, reducing the perceived complexity for users while maintaining strong security

Inventive Principle:
Principle #25Self-service

3Reliability

If device qualification checks are performed to ensure secure document access, then data security is improved, but the time required for document access increases

Engineering Contradiction:
Improvedata securityVSAvoiddocument access time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Device qualification assessments are performed in advance before document access is needed. The device management system evaluates hardware and software attributes beforehand, stores the qualification status, and uses this pre-assessed information to quickly grant or deny document access without repeating the full evaluation process each time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback on device qualification status and document accessibility to users. This feedback mechanism helps users understand why access is granted or denied based on their device's attributes, reducing confusion and repeated access attempts that would waste time

Inventive Principle:
Principle #23Feedback

AI summary

A device management system is configured to manage access to electronic documents on client devices using policies. The policies specify one or more download and processing restrictions to be enforced with respect to the particular electronic document at client devices for example, particular hardware and software configurations that are required at client devices before data is permitted to be downloaded to those client devices. The policies may also specify other requirements that must be satisfied before data is permitted to be downloaded to those client devices, for example, user authentication.
