Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing systems face inefficiencies due to reliance on operator attention for refilling consumables, leading to interruptions in continuous operation as storage holders run out of supplies, as existing systems lack automated and optimized methods for identifying and addressing low consumable levels.
Innovation Solution
A printer system equipped with detectors for monitoring consumable status, proximity sensors to track operator location, and a controller that assigns tasks to operators based on distance and adapts timing for refill signals, ensuring timely replenishment and minimizing delays by using proximity sensors and calculators to optimize alert timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acoustic or visual signals are used to prompt operators to refill storage holders, then operators can be alerted to consumable levels, but the system efficiency deteriorates because refill actions depend on operator attention and may be delayed
Solution Approach 1:
The system enables self-service through automated detector-monitoring-refill workflows. Detectors automatically monitor consumable levels and trigger refill processes without continuous human intervention, allowing the system to service itself and eliminate delays caused by operator attention dependencies
Solution Approach 2:
The system implements feedback loops where detectors continuously monitor consumable levels and provide real-time information to the control unit, which then prompts operators or automatically initiates refill actions. This closed-loop feedback ensures timely responses to consumable depletion without relying on operator vigilance
2Ease of operation
If multiple operators are present in the printing system environment, then task distribution is possible, but the system complexity increases due to needing to identify and assign tasks to specific operators
Solution Approach 1:
The system replaces manual operator identification and task assignment with electronic identification means (RFID tags, biometric sensors, or other automated recognition systems) and electronic communication networks. This substitution automates the matching of operators to tasks based on proximity and task lists, reducing manual coordination complexity
Solution Approach 2:
The control unit acts as an intermediary that receives detector signals, identifies nearby operators through electronic identification means, matches operators to appropriate tasks from task lists, and communicates assignments. This intermediary layer simplifies the complex interaction between multiple operators and the printing system
3Device complexity
If storage holders are refilled manually based on operator attention, then system simplicity is maintained, but downtime increases when consumables are depleted
Solution Approach 1:
The system performs preliminary actions by detecting consumable levels in advance and issuing refill prompts before complete depletion occurs. The control unit monitors levels continuously and alerts operators or automatically initiates refill processes proactively, preventing operational interruptions
Solution Approach 2:
The system ensures continuity of useful action through automated monitoring and refill processes that eliminate interruptions. By maintaining continuous detection and prompt refilling, the printing system operates without downtime, keeping the productive action continuous

AI summary
The present invention relates to a printer and method for printing images. The printer comprises a set of storage holders for housing consumables used for printing images. Each storage holder is provided with a detector for detecting a status of the storage holder. A proximity sensor is arranged for measuring a distance from the printer to at least one wearable associated with an operator for maintaining a condition of the consumables present in the set of storage holders. A controller of the printer is configured to select the operator based on the measured distance from the printer to the at least one wearable, to check whether or not a task is assigned to the operator and stored on the wearable associated with the operator to abolish the status of a storage holder of the set of storage holders, in case of a positive check, to process the status of the storage device, and to transmit, when the status of the storage holder corresponds to a predetermined threshold, a signal to the wearable associated with the selected operator, the signal corresponding to the task for the operator to abolish the status of the storage holder.
