Solution Overview

Problem

Existing notification systems for consumable product levels in printing devices often burden specific users and fail to distribute notifications fairly, leading to inefficient resource management and potential delays in urgent situations.

Innovation Solution

A notification system that includes an electronic device with a detecting unit for consumable product levels, multiple terminal devices, and a determining unit that selects the most appropriate user based on usage history, location, and operational status to ensure fair and timely notifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system notifies a specific user (administrator or fulltime operator) of the predicted time when the printing device will run out of paper, then the notification can be delivered reliably, but this places a great burden on this particular person

Engineering Contradiction:

Improvenotification delivery reliabilityVSAvoiduser burden

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The notification system segments the user base into multiple categories (frequent users, infrequent users, administrators) and applies different notification strategies to each segment. This allows the system to distribute notification burdens across multiple users rather than concentrating them on a single person, while still ensuring reliable notification delivery through targeted approaches.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system applies different notification qualities to different users based on their usage patterns. Frequent users receive notifications at specific thresholds, while infrequent users are notified differently. This local differentiation ensures that each user receives appropriate notification timing and frequency, reducing overall burden while maintaining reliability.

Inventive Principle:

Principle #3Local quality

2Ease of manufacture

If the system notifies the last terminal device that outputted printing data, then the notification can be sent to a known device, but there is a possibility that a user that does not use the printing device very often may be notified more frequently than a user that uses the printing device frequently, resulting in an unfair distribution among the users

Engineering Contradiction:

Improvenotification system simplicityVSAvoidfairness of notification distribution

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The notification system dynamically adjusts its behavior based on real-time usage data. It continuously monitors printing activity, tracks user behavior patterns, and adapts notification strategies accordingly. This dynamic approach ensures that notification frequency is automatically adjusted to match actual usage, preventing unfair distribution while maintaining system simplicity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms that monitor user responses to notifications and adjust future notification strategies based on this feedback. By analyzing which users respond to notifications and how frequently they use the printing device, the system refines its notification algorithm to achieve fairer distribution, eliminating the unfairness described in the contradiction.

Inventive Principle:

Principle #23Feedback

3Reliability

If the system notifies users when there is very little paper or consumable product remaining, then users can be alerted to take measures, but it does not specify which user should be notified, leading to potential delays in urgent situations

Engineering Contradiction:

Improvetimely action assuranceVSAvoidnotification selection logic

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary analysis of usage patterns and predicts when consumable products will be depleted before actually notifying users. By proactively determining the optimal notification timing based on historical data and usage trends, the system ensures users are notified at the right moment to take timely action, while the complexity of selection logic is managed through automated prediction algorithms.

Inventive Principle:

Principle #10Preliminary action

4Ease of operation

If the system uses multiple destination determining units to select notification destinations, then fair distribution among users can be achieved, but the system complexity increases

Engineering Contradiction:

Improvefairness of notification distributionVSAvoidnotification system structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The notification system employs a universal determination unit that can handle multiple notification scenarios and user types through a single integrated algorithm. Rather than requiring separate specialized units for different notification types, the system uses one multi-functional unit that adapts its behavior based on usage patterns, achieving fair distribution while minimizing structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

When paper needs to be loaded into a printing device but there is no particular hurry, a destination to issue a paper load notification is set to a user having the greatest amount of paper usage. When paper must be loaded into a printing device as quickly as possible, the notification destination is set to a user that has issued a print command within a prescribed time period prior to the current time.
