Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems require software customization at the printing device to achieve interface customization, which is cumbersome and complicates software upgrades, and existing integration methods lack flexibility and scalability.
Innovation Solution
A printing system that intercepts commands at the digital front end, applies transforms to these commands to generate instructions understandable by the printing device, allowing interface customization without modifying the device's software, and supports multiple transforms for different payload types and systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If software customization is performed at the printing device to achieve interface customization, then interface flexibility is improved, but device complexity and upgrade difficulty increase
Solution Approach 1:
The patent introduces a Digital Front End (DFE) as an intermediary component between the printing device and external systems. The DFE contains a transform engine that converts commands from various protocols (XML, JSON, etc.) into device-specific instructions without requiring modifications to the printing device's core software. This mediator approach enables interface customization while preserving the device's original software architecture.
Solution Approach 2:
The patent segments the command processing functionality by separating the protocol interpretation and transformation logic into a distinct DFE module, while the printing device maintains its original instruction execution capability. This segmentation allows the interface layer to be customized independently from the device core, enabling upgrades without re-customization.
2Productivity
If vendor-specific integration is implemented to enable efficient production, then integration capability is improved, but system adaptability deteriorates
Solution Approach 1:
The patent implements a universal transform engine within the DFE that can handle multiple protocol types (XML, JSON, and other structured data formats) through a single unified architecture. The transform engine uses configurable templates and mappings that can be adapted to different vendor protocols without requiring separate integration implementations, thus achieving both efficiency and versatility.
Solution Approach 2:
The patent enables protocol adaptation by changing parameters within the transform engine configuration rather than modifying the underlying device functionality. By adjusting transform parameters, mapping rules, and protocol specifications in the DFE, the system can integrate with different vendors while maintaining consistent device operation and production efficiency.
3Adaptability or versatility
If product customization is performed to enable vendor to vendor integration, then integration capability is improved, but ease of manufacture and maintenance deteriorates
Solution Approach 1:
The patent performs preliminary action by pre-configuring transform templates and mapping rules in the DFE that can be reused across different integrations. Rather than customizing the device software for each integration scenario, the system prepares configurable transformation profiles in advance that can be activated through parameter changes, simplifying both initial setup and future upgrades.
Data Source
AI summary
A printing system includes a third party system and a printing device. The printing device includes a digital front end (DFE) that processes jobs and collects information about the printing device. The third party system sends a payload, such as a message or command, to the DFE over connection having a specified communication protocol. The DFE applies an interface having a transform to the payload to convert the information of the payload into a format useable by the DFE.
