Server Benefit Granting Based on Printer Cartridge Type
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for printers lack the ability to dynamically grant benefits to users based on the type of cartridge installed in the printer, limiting personalized service offerings.
Innovation Solution
A non-transitory computer-readable recording medium storing instructions for a server to receive user identification and service requests, and to determine whether to grant a benefit based on the type of cartridge attached to the printer, specifically distinguishing between cartridges supplied with the printer at the time of sale and those that were not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the server grants benefits to all users regardless of cartridge type, then user satisfaction and service inclusivity are improved, but system revenue and cartridge differentiation strategy are worsened
Solution Approach 1:
The server implements differentiated benefit granting based on cartridge type. Users with first-type cartridges (supplied at printer sale) receive first benefits, while users with second-type cartridges (not supplied at sale) receive second benefits. This local quality differentiation resolves the contradiction by providing tailored service quality to different user groups, maintaining inclusivity while protecting revenue through strategic benefit differentiation.
Solution Approach 2:
The system changes the benefit parameter based on cartridge type identification. The server receives cartridge information from the printer, identifies the cartridge type, and dynamically adjusts the benefit granted accordingly. This parameter change approach allows the system to maintain high service inclusivity while controlling revenue loss through conditional benefit allocation.
2Loss of energy
If the server implements cartridge type verification for benefit granting, then revenue protection and cartridge differentiation are improved, but system complexity and user operation difficulty are worsened
Solution Approach 1:
The printer automatically transmits cartridge information to the server without requiring user intervention. The server autonomously receives, processes, and verifies cartridge type information, then determines benefit eligibility. This self-service mechanism protects revenue through automated verification while minimizing system complexity from the user perspective, as no additional user actions are required.
Solution Approach 2:
The system implements a feedback loop where the printer sends cartridge information to the server, the server processes this information to determine benefit eligibility, and the benefit decision is communicated back to the user. This feedback mechanism enables revenue protection through continuous verification while managing system complexity through automated information exchange between components.
3Measurement precision
If the server provides detailed cartridge verification, then benefit accuracy and user-specific service quality are improved, but information processing time and system response time are worsened
Solution Approach 1:
The printer pre-transmits cartridge information to the server before the user requests service. The server stores and processes this cartridge information in advance, so when a service request is made, the verification process is already complete or can be quickly finalized. This preliminary action ensures accurate benefit determination while minimizing service response time.
Solution Approach 2:
The server implements selective verification based on service context. For routine services, the server uses previously verified cartridge information without re-verification. For benefit-critical operations, detailed verification is performed. This partial verification approach maintains benefit accuracy while reducing unnecessary processing time for routine operations.

AI summary
A server may receive, from a terminal device, user identification information and a service request for requesting that provision of the service be started and receive, from a printer, cartridge information indicating a type of a cartridge currently attached in the printer. The server may, in a case where the user identification information and the service request are received from the terminal device and the cartridge information indicates a first type of cartridge supplied with the printer at time of sale of the printer, grant a first benefit to a user identified by the user identification information. In a case where the user identification information and the service request are received from the terminal device and the cartridge information indicates a second type of cartridge that was not supplied with the printer at the time of sale of the printer, the first benefit may not be granted.
