Print Engine Scheduling Conflict Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining why print media sheets are not delivered at the correct time to marking engine components is challenging due to complex interactions between job submission flows, print engine timing models, and scheduling methods, often requiring expert programmers to decipher system logs, making it time-consuming and difficult for non-experts to understand and resolve scheduling conflicts.
Innovation Solution
The system generates an augmented timing schedule with explanatory text for print media processing, allowing users to visualize and understand scheduling constraints through a Gantt chart interface, enabling non-experts to identify and address conflicts by adding descriptive annotations to the print engine timing model and allowing rescheduling with conflict explanations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If detailed timing schedules and scheduling constraints are implemented to manage print engine operations, then printing productivity and scheduling precision are improved, but the complexity of understanding and diagnosing scheduling conflicts increases significantly
Solution Approach 1:
The patent introduces an intermediary diagnostic system that translates complex scheduling data into understandable visual representations. The Gantt chart interface acts as a mediator between the complex scheduling engine and users, allowing non-experts to understand scheduling conflicts without simplifying the underlying complex scheduling logic.
Solution Approach 2:
The patent replaces the need for expert programmers to manually analyze system logs with an automated diagnostic system. The system automatically generates visual schedules and conflict explanations, substituting manual expert analysis with an automated information processing and presentation system.
2Measurement precision
If expert programmers manually analyze system logs to determine scheduling conflicts, then accurate diagnosis is achieved, but the time required and expertise level needed increase significantly
Solution Approach 1:
The system performs self-diagnosis by automatically analyzing scheduling data and generating conflict explanations. The diagnostic capability is built into the scheduling system itself, allowing it to identify and explain its own conflicts without requiring external expert intervention, thereby reducing both time and expertise requirements.
Solution Approach 2:
The system provides immediate feedback through the Gantt chart interface, automatically explaining scheduling conflicts when users interact with the visual schedule. This real-time explanatory feedback eliminates the need for time-consuming manual log analysis while maintaining high diagnostic accuracy.
3Manufacturing precision
If comprehensive scheduling models and timing constraints are used to manage print media delivery, then delivery precision is improved, but the difficulty of detecting and understanding conflicts increases
Solution Approach 1:
The patent segments the complex scheduling information into manageable visual components displayed on the Gantt chart. Each scheduling element is represented as a separate visual block with explanatory text, allowing users to detect and understand conflicts by examining individual segments rather than analyzing the entire complex schedule at once.
Solution Approach 2:
The system uses visual differentiation in the Gantt chart to highlight scheduling conflicts and different states. By applying visual cues such as color coding or highlighting to conflicting elements, the system makes conflicts easily detectable without simplifying the underlying precision scheduling model.
Data Source
AI summary
Methods and devices receive scheduling constraints for sheets of print media being processed as a print job through a printing device, and prepare a timing schedule for each of the sheets of print media based on the scheduling constraints. The timing schedule determines a location of each of the sheets of print media relative to the processing components of the printing device and relative to a linear time scale. Such methods and devices augment the timing schedule to produce an augmented timing schedule by adding explanatory text to the timing schedule, and receive user input selecting a portion of the augmented timing schedule. In response to the user input that selects a portion of the augmented timing schedule, the methods and devices output corresponding portions of the explanatory text that correspond to a location on the linear time scale represented by the selected portion of the augmented timing schedule.
