Automatic Consumable Delivery System for Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing consumable delivery systems for printing apparatuses often go unused due to lack of knowledge or forgotten contracts, leading to user inconvenience and inefficiency, especially when toner levels are low.
Innovation Solution
A system comprising an information processing apparatus and a server that automatically requests and manages consumable delivery contracts based on toner levels, using a reader to scan codes and display screens for user input, thereby simplifying the process and ensuring timely replenishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contract-based automatic delivery system is implemented, then delivery reliability is improved, but device complexity increases due to contract management requirements
Solution Approach 1:
The system enables self-service by automatically detecting consumable levels through sensors, generating delivery requests without user intervention, and managing the entire contract execution process autonomously. The printing apparatus itself monitors its consumable status and triggers deliveries based on pre-established contracts.
Solution Approach 2:
Contracts are established in advance before consumable depletion occurs. The system pre-configures delivery parameters, thresholds, and supplier agreements beforehand, so that when consumables reach critical levels, the pre-arranged contracts can be executed immediately without requiring user decision-making or manual ordering.
2Ease of operation
If manual ordering is required when toner is low, then ease of operation is reduced, but system complexity is decreased
Solution Approach 1:
The system performs automatic self-ordering by monitoring consumable levels through integrated sensors and autonomously generating delivery requests when thresholds are reached. This eliminates the need for users to manually check toner levels or place orders, completely resolving the operational inconvenience while the system manages complexity internally.
Solution Approach 2:
The system implements continuous feedback loops where sensors monitor consumable levels in real-time, compare them against predetermined thresholds, and automatically trigger ordering actions when conditions are met. This closed-loop control ensures timely replenishment without user intervention while maintaining systematic management of the ordering process.
3Productivity
If automatic delivery contracts are promoted, then productivity is improved, but loss of information increases due to user ignorance of the system
Solution Approach 1:
The system provides multiple feedback channels to keep users informed about contract status and consumable levels. Notification mechanisms (display screens, communication interfaces) continuously update users on system state, contract execution status, and delivery schedules, ensuring users remain aware of the automatic system's operations without requiring their active participation.
Data Source
AI summary
A delivery system including an information processing apparatus operated by a user, a printing apparatus and a server that instructs delivery of a consumable of the printing apparatus. The information processing apparatus requests screen information for making a contract related to the delivery of the consumable to the server, displays a screen based on the screen information received from the server, and transmit registration information input on the screen to the server. The server creates the screen information and transmits the screen information to the information processing apparatus, makes a contract of the delivery of the consumable to be used in the printing apparatus with the user, based on the registration information, and delivers the consumable to the user when a remaining amount of the consumable is less than a predetermined amount in the printing apparatus.
