Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of digital front-end (DFE) systems requires significant time and resources to modify software for connecting with new printing devices, often disrupting existing connectivity modules and the DFE system itself.
Innovation Solution
Implementing a printing device connectivity manager with installable printing connectivity modules and APIs that allow dynamic interaction with various printing devices, enabling on-demand connectivity without modifying the DFE software, using technologies like TCP/IP, USB, Bluetooth, and NFC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DFE software is modified to connect with new printing devices, then connectivity with new devices is achieved, but development time and resources increase significantly
Solution Approach 1:
The system segments connectivity functionality into separate, modular printing device connectivity modules that can be independently developed, installed, and managed. Each module handles connectivity to specific printing devices or device types, allowing the core DFE software to remain unchanged while adding support for new devices through module installation.
Solution Approach 2:
The printing device connectivity manager provides a universal platform that can accommodate multiple printing devices and connectivity protocols through a common interface. The manager orchestrates communication between the DFE and various printing devices using standardized APIs, enabling one system to serve multiple device types without requiring separate software modifications for each device.
2Adaptability or versatility
If DFE software is modified to add new printing device connectivity, then new device support is enabled, but existing connectivity modules and system stability are disrupted
Solution Approach 1:
The connectivity functionality is extracted from the core DFE software and placed into separate, removable printing device connectivity modules. This extraction allows new connectivity capabilities to be added without touching or risking the stability of the core system or existing connectivity modules. The manager acts as an intermediary that coordinates between the stable core system and the modular, updatable connectivity components.
3Adaptability or versatility
If DFE software is recompiled for each new printing device, then device-specific connectivity is achieved, but resource consumption and complexity increase
Solution Approach 1:
The printing device connectivity manager serves as an intermediary layer between the DFE and various printing devices. It provides a standardized interface and orchestration mechanism that simplifies device-specific connectivity requirements. Instead of modifying the core DFE for each device, the manager handles device-specific protocols and communication patterns through its modular connectivity modules, reducing overall system complexity.
