Periodic Consumable Delivery Scheduling for Image Forming Apparatuses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing consumable delivery in image forming apparatuses lead to irregular deliveries, increasing the burden on users with unexpected package reception and interfering with business operations, particularly in high-volume printing environments.
Innovation Solution
A periodic delivery management system that determines delivery dates based on consumable usage, ensuring regular and efficient replenishment by managing stock levels and reducing unexpected package reception through real-time inventory monitoring and automated delivery instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional systems place orders based on predicted replacement dates and threshold values, then consumable stock is maintained, but delivery becomes irregular and increases the burden on users for receiving packages
Solution Approach 1:
The patent implements periodic delivery by establishing fixed delivery cycles (e.g., weekly or monthly) instead of irregular threshold-based ordering. The system determines delivery timing based on predetermined cycles and notifies users in advance, transforming the unpredictable packaging reception into a regular, expected event that users can plan for, thereby reducing operational burden while maintaining stock reliability
Solution Approach 2:
The system incorporates feedback mechanisms by monitoring actual consumable usage amounts and comparing them with delivery cycle timing. This feedback loop allows the system to adjust future delivery amounts and timing based on real consumption patterns, ensuring stock maintenance while optimizing delivery regularity to minimize user burden
2Reliability
If orders are placed when stock reaches a predetermined threshold, then consumable availability is ensured, but the number of deliveries increases and delivery burden increases
Solution Approach 1:
Instead of triggering deliveries at arbitrary threshold points, the system establishes fixed periodic delivery intervals. This consolidates multiple small threshold-based orders into fewer, larger periodic deliveries, reducing the total number of deliveries and associated time burden while ensuring consumable availability through predictable restocking cycles
Solution Approach 2:
The system performs preliminary calculations to determine optimal delivery amounts in advance of each delivery cycle, based on projected consumption during the upcoming period. This preliminary action prevents last-minute threshold-triggered orders and allows for consolidated, efficient deliveries that reduce overall delivery burden while maintaining availability

AI summary
A periodic delivery management apparatus for managing periodic delivery of consumables used in an image forming apparatus, the periodic delivery management apparatus includes a hardware processor that: determines whether or not a periodic delivery reference date of the consumables to the image forming apparatus has come; acquires a used amount of the consumables in the image forming apparatus; determines a delivery amount of the consumables by periodic delivery based on the used amount when it is determined that it is the periodic delivery reference date; and outputs a periodic delivery instruction including the delivery amount.
