Solution Overview

Problem

Existing printer systems lack efficient methods for notifying users about consumable replacements, particularly ink levels, and do not account for discount sales or optimal purchasing options based on consumable usage patterns.

Innovation Solution

A system that includes a control device and computer-readable storage medium to monitor consumable levels, predict replenishment times, and notify users of discount sales or optimal purchasing options based on consumable usage patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system notifies users of consumable replenishment needs, then users can maintain adequate consumable levels, but users may miss discount opportunities or make suboptimal purchasing decisions

Engineering Contradiction:
Improveconsumable availabilityVSAvoiddiscount sale information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary actions by calculating predicted execution times for consumable replenishment before the actual need arises. It then compares these predicted times with discount sale periods in advance, enabling users to make informed purchasing decisions that balance both consumable availability and cost savings.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces feedback by notifying users of the relationship between predicted consumable depletion and discount sale periods. This feedback loop enables users to adjust their purchasing behavior based on the timing information provided, optimizing both reliability and cost-effectiveness.

Inventive Principle:
Principle #23Feedback

2Ease of manufacture

If the system provides basic replenishment notifications, then implementation is simple, but it does not optimize user purchasing decisions based on discount periods

Engineering Contradiction:
Improvesystem implementation complexityVSAvoidpurchasing efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The system performs preliminary calculations of predicted execution times and compares them with discount sale periods before users make purchasing decisions. This preliminary analysis optimizes purchasing efficiency by providing timely, actionable information without requiring complex manual intervention.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If the system calculates predicted execution times and compares with discount periods, then purchasing optimization is achieved, but processing complexity increases

Engineering Contradiction:
Improvepurchasing optimizationVSAvoidnotification control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically calculating predicted execution times, comparing them with discount sale periods, and generating appropriate notifications without user intervention. This automation achieves purchasing optimization while keeping the user interface simple and intuitive.

Inventive Principle:
Principle #25Self-service

4Loss of time

If the system notifies users about consumable levels, then users can plan replacements, but users may purchase at non-optimal times without discount consideration

Engineering Contradiction:
Improveplanning time for replacementVSAvoidpurchasing cost
Core Design Contradiction:
Loss of timeVSLoss of energy

Solution Approach 1:

The system performs preliminary comparison between predicted execution times and discount sale periods, providing users with advance notice of optimal purchasing opportunities. This enables users to plan replacements in advance while capturing discount savings, addressing both time planning and cost reduction needs.

Inventive Principle:
Principle #10Preliminary action

AI summary

A control device controls a notification regarding a consumable. The control device has an acquisition unit which acquires remaining amount data regarding a remaining amount of a consumable in a printer, a calculation unit which calculates a predicted execution time, at which predetermined processing relating to replenishment of the consumable is executed, with using the remaining amount data, a determination unit which determines whether a first specific condition is satisfied, with using a plurality of information including a period for discount sale of the consumable and the predicted execution time, and a notification unit which performs processing for notifying a user of first information including information regarding the discount sale of the consumable, in a case where it is determined that the first specific condition is satisfied.
