Multi-Function Device Cluster Decontamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-function device (MFD) usage policies fail to effectively prevent the spread of pathogens by not providing real-time information on previous users and usage times, leading to potential health risks when one MFD is used in a cluster, as pathogens can remain airborne.
Innovation Solution
Implementing a method to organize MFDs into clusters, where deactivation and reactivation are controlled based on usage, with a decontamination process initiated after detected use, using active or passive processes, and notifications sent to users about unavailable MFDs and alternative locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If MFDs are deactivated after use to prevent pathogen spread, then health safety is improved, but device availability and productivity deteriorate
Solution Approach 1:
The patent divides MFDs into clusters based on spatial proximity and shared ventilation systems. When one MFD in a cluster is used, the entire cluster is deactivated and undergoes decontamination. This segmentation approach ensures health safety by preventing pathogen spread between nearby devices while allowing the system to maintain productivity through coordinated cluster management rather than individual device isolation.
Solution Approach 2:
The patent implements preliminary deactivation of MFDs before actual contact with users occurs. When an MFD is used, the system immediately deactivates the MFD and notifies users, preventing potential pathogen exposure before users can be affected. This preliminary action ensures health safety while minimizing productivity impact by quickly transitioning to the next available device.
2Object-affected harmful factors
If real-time monitoring and deactivation are implemented, then health safety is improved, but system complexity increases
Solution Approach 1:
The patent uses a universal notification mechanism that serves multiple functions: informing users of MFD unavailability, providing health safety information, and coordinating cluster deactivation. This multi-functional approach improves health safety through real-time monitoring while avoiding the need for separate complex systems for each function, thereby limiting the increase in system complexity.
Solution Approach 2:
The patent implements a feedback loop where MFD usage is detected, deactivation is triggered, and users are notified. The system continuously monitors MFD status and adjusts operations accordingly. This feedback mechanism ensures health safety by immediately responding to usage events while maintaining relatively simple system architecture through automated, rule-based responses.
3Object-affected harmful factors
If decontamination processes are activated frequently, then health safety is improved, but energy consumption increases
Solution Approach 1:
The patent dynamically adjusts decontamination operations based on real-time MFD usage patterns. Decontamination is activated only when an MFD is actually used, rather than operating continuously. This dynamic approach ensures health safety by targeting decontamination to specific events while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The patent implements periodic decontamination cycles triggered by MFD usage events. Rather than continuous decontamination, the system performs decontamination periodically in response to detected usage. This periodic action maintains health safety by addressing contamination after each use while optimizing energy consumption by avoiding unnecessary continuous operation.

AI summary
A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes detecting use of the MFD, wherein the MFD is associated with a plurality of MFDs that are designated as a cluster within a location, deactivating the MFD in response to use of the MFD being detected, transmitting a first notification to deactivate the plurality of MFDs within the cluster in response to use of the MFD being detected, initiating a decontamination process within the location in response to the use of the MFD being detected, receiving an indication that the decontamination process is completed, transmitting a second notification to reactivate the plurality of MFDs within the cluster, and reactivating the MFD.
