Extending Multifunction Device Services via Shared Framework
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-function devices (MFDs) and mobile communications devices operate disconnected, making it difficult to achieve a hybrid workflow and seamlessly extend MFD functionality onto mobile devices, leading to configuration burdens and limited composite operations.
Innovation Solution
The system securely connects MFDs and mobile communications devices using QR codes or NFC, combining their hardware and software resources to perform composite operations, with a shared extensibility framework that expires after inactivity and requires physical proximity, allowing services like scanning, copying, and GPS integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MFD and mobile communications device operate disconnected, then device complexity is reduced and operation is simpler, but functionality extension and composite operations are limited
Solution Approach 1:
The patent introduces a shared extensibility framework as an intermediary layer that enables MFD and mobile communications device to communicate and extend functionality without direct complex integration. This framework acts as a mediator that handles resource sharing, service discovery, and data exchange between the disconnected devices, resolving the contradiction by providing structured connectivity without full system integration.
Solution Approach 2:
The shared extensibility framework provides universal interfaces and standardized protocols that allow different MFDs and mobile devices to interoperate through common service definitions. This multi-functionality approach enables any MFD to extend to any mobile device using the same framework, reducing complexity through standardization while maintaining high adaptability.
2Ease of operation
If MFD services are made always available on local host, then service accessibility is improved, but network discovery and configuration burden increases when accessing remote hardware
Solution Approach 1:
The framework implements self-service mechanisms where the mobile communications device automatically discovers available MFD services and configures connections without manual intervention. The system performs automatic service registration, capability negotiation, and resource allocation, eliminating the configuration burden while maintaining always-available service access through the shared extensibility framework.
3Reliability
If connection requires physical proximity and expires after inactivity, then security is improved, but operational continuity is reduced
Solution Approach 1:
The connection mechanism dynamically adjusts its behavior based on operational context. The framework can extend connection duration through explicit user actions or service requirements while maintaining proximity-based security validation. This dynamic connection management allows the system to balance security with operational continuity by adapting connection policies to current usage patterns rather than applying fixed restrictions.

AI summary
Methods and systems for transparently extending a multi-function device onto a mobile communications device. The mobile communications device and the multi-function device can be securely connected utilizing a random code displayed on a user interface of the MFD. An extensibility application associated with the MFD can be transparently combined with an execution environment of the mobile communications device to offer a number of services. A hardware and software resource of the MFD and the mobile communications device can be combined to perform composite operations involving data from both devices. The connection can expire after a period of inactivity and require physical proximity to be established to prevent unwanted access to the MFD. Such an approach establishes a shared extensibility framework for the multifunction device and the mobile communications device as a single execution environment.
