Dynamic Print Queue Prioritization via Wireless Signal Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face challenges in optimizing printing order management, particularly in reducing user wait times when multiple print jobs are queued, as existing systems do not efficiently prioritize print jobs based on user proximity using wireless communication signals.
Innovation Solution
The apparatus uses a processor to identify approaching terminals via wireless communication signal strength, allowing it to dynamically change the printing order of print data to advance jobs related to those users, thereby reducing wait times for users who are physically closer and minimizing inconvenience to others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If print jobs are processed in sequential order based on receipt time, then processing fairness is maintained, but user wait time increases when users are physically present at the device
Solution Approach 1:
The patent implements dynamic printing order adjustment by continuously monitoring wireless communication signal strength between the image forming apparatus and user terminals. When a user approaches the device (indicated by increased signal strength), their print jobs are automatically prioritized and moved to the front of the queue, transforming the static sequential processing into a dynamic system that adapts to real-time user presence and reduces wait time fairly.
2Loss of time
If print jobs are prioritized based on user proximity, then user wait time is reduced, but system complexity increases due to wireless signal monitoring
Solution Approach 1:
The patent uses wireless communication signals as an intermediary mechanism to detect user proximity without requiring direct physical interaction or complex sensors. The existing wireless communication infrastructure (Wi-Fi, Bluetooth) serves as the detection medium, allowing the system to monitor signal strength between the apparatus and user terminals to determine priority levels, thereby avoiding additional complex hardware while still achieving proximity-based prioritization.
3Productivity
If multiple print jobs are queued in advance, then processing efficiency is maintained, but flexibility to accommodate urgent prints is reduced
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors wireless signal strength from user terminals and uses this information to dynamically adjust the print job queue in real-time. When a user approaches the device (signal strength exceeds threshold), the system receives feedback about user presence and automatically reprioritizes their jobs, allowing the queue to adapt to urgent needs while maintaining overall processing efficiency through continuous optimization rather than rigid predetermined ordering.

Function Achieved in This Case
This solution enables quicker retrieval of print data for users by advancing their print jobs when they approach the device, reducing wait times and preventing increased delays for other users, especially in scenarios where urgent prints are needed amidst a queue of other jobs.
Implementation Method 1
