Solution Overview

Problem

Current document delivery mechanisms to mobile devices are limited, as they often require technical knowledge for file transfer and lack permission-based access, and do not optimize document presentation for varying mobile device formats, hindering integration into networked office environments.

Innovation Solution

A system and method utilizing a mobile device printer driver that allows users to transfer documents by treating the mobile device as a printer, enabling permission-based access and optimizing document presentation through a printer metaphor, allowing control over content and presentation aspects like page format and orientation, and supporting multiple file formats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional document delivery mechanisms (e-mail, HTTP, FTP) are used to transfer documents to mobile devices, then document transfer capability is provided, but user-friendly permission-based access control and optimized document presentation for varying mobile formats are not achieved

Engineering Contradiction:
Improvepermission-based access controlVSAvoidintegration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mobile device is made universally accessible as a document delivery destination by implementing a printer driver that can receive documents from multiple sources (e-mail, network, local) and deliver to various mobile formats. The system provides multi-functional document delivery through a unified printer interface, enabling permission-based access control while maintaining ease of operation across different delivery scenarios

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

Solution Approach 2:

A printer driver acts as an intermediary layer between traditional document delivery systems and mobile devices. This intermediary provides permission-based access control, formats documents appropriately for mobile screens, and bridges the gap between desktop document management systems and mobile device capabilities without requiring complex integration

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If documents are transferred to mobile devices without considering mobile device constraints, then document transfer is simplified, but document presentation quality deteriorates on varying screen sizes and resolutions

Engineering Contradiction:
Improvedocument transfer efficiencyVSAvoiddocument presentation quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system applies local quality by detecting the specific mobile device characteristics (screen size, resolution, format) and optimizing the document presentation specifically for that device. Each document is locally adapted to match the target device's display capabilities, ensuring high presentation quality while maintaining efficient transfer through automated format detection and conversion

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If mobile devices are integrated into networked office environments, then document accessibility is improved, but security and permission management become more complex

Engineering Contradiction:
Improvenetwork integration capabilityVSAvoidpermission management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The printer driver provides universal permission management that works across networked office environments, enabling a single interface for controlling document access to mobile devices. The system handles multiple users, devices, and permission levels through a unified mechanism, improving network integration while keeping permission management simple through centralized control

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