Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Multi-function devices (MFDs) face inefficiencies and increased costs due to premature replacement of worn-out components, as existing life set points are not tailored to individual operating conditions, leading to either early replacement or device inoperability.

Innovation Solution

The method involves monitoring operating parameters of MFD components, calculating unique life set points based on these parameters, and automatically adjusting default set points, while also scheduling service appointments to minimize technician visits by analyzing usage patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If default life set points are used for component replacement, then replacement timing is simple to determine, but components may be replaced too soon or too late leading to increased costs and inefficiencies

Engineering Contradiction:

Improvecomponent replacement efficiencyVSAvoidcomponent replacement timing accuracy

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic adjustment of life set points based on monitored operating parameters. The system continuously collects data on component usage conditions and automatically modifies replacement thresholds to match actual wear patterns, transforming static default values into adaptive, condition-based set points that optimize both timing accuracy and operational efficiency

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system establishes a feedback loop where operating parameters are continuously monitored and fed back to recalculate life set points. This closed-loop approach allows the system to learn from actual component performance and usage conditions, progressively improving replacement timing accuracy while maintaining simple automated operation

Inventive Principle:

Principle #23Feedback

2Ease of operation

If components are replaced based on fixed default life set points, then maintenance scheduling is straightforward, but service technicians must make on-site replacements causing device downtime

Engineering Contradiction:

Improvemaintenance scheduling simplicityVSAvoiddevice downtime during component replacement

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of operating parameters and predicts component failure timing in advance. By calculating updated life set points before actual component degradation occurs, the system enables proactive scheduling of replacements during planned maintenance windows rather than emergency on-site interventions, reducing unplanned device downtime

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automates the monitoring, analysis, and scheduling functions that would otherwise require service technician intervention. By enabling the MFD to self-monitor component health and self-schedule maintenance activities, the system eliminates the need for technician travel and on-site diagnosis, allowing replacements to be scheduled during low-usage periods with minimal operational disruption

Inventive Principle:

Principle #25Self-service

AI summary

A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes monitoring operating parameters of a component in the MFD, calculating a life set point for the component based on the operating parameters, and changing a default life set point for the component stored in a memory of the MFD to the life set point that is calculated based on the operating parameters.
