Solution Overview

Problem

Users face delays in receiving printing services due to the unavailability of contract consumable items, especially when switching from a retail mode to a subscription mode or when contract consumable items are not prepared.

Innovation Solution

A printing apparatus with a controller that can operate in both contract and non-contract modes, equipped with a consumable item that includes a memory for storing type information. The controller executes an information writing process to treat the consumable item as a contract type, allowing the printing apparatus to simulate operation in the contract mode even if a contract consumable item is not installed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a subscription contract is concluded and contract consumable items are used, then printing service at fixed-sum payment is enabled, but printing operation cannot be performed until the contract consumable items are delivered and installed

Engineering Contradiction:

Improveprinting service availabilityVSAvoiddelivery waiting time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent uses type information as an intermediary to enable the printing apparatus to recognize and accept consumable items of different types (contract or non-contract). By writing appropriate type information into the consumable item's memory, the system mediates between the physical consumable item and the contractual printing service mode, allowing seamless transition and eliminating delivery waiting time.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the parameter of consumable item type information stored in memory to enable different operating modes. By modifying the type information from non-contract to contract type, the printing apparatus switches from retail mode to subscription mode, allowing the same physical consumable item to serve different service models without physical replacement.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If contract consumable items are delivered in multiple installments, then complete set installation is required before printing service starts, but printing operation is delayed until all items arrive

Engineering Contradiction:

Improvesubscription service activationVSAvoidprinting operation start time

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent performs preliminary action by pre-writing contract type information into the consumable item's memory before the printing service actually begins. This allows the printing apparatus to be pre-configured for subscription mode operation, so that when consumable items are installed (even partially), the system can immediately activate printing service without waiting for complete set delivery.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If contract consumable items are consumed earlier than expected or delivery location is unsuitable, then commercially available consumable items must be used, but printing service continuity is interrupted

Engineering Contradiction:

Improveprinting service continuityVSAvoidconsumable item flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent makes the consumable item universal by enabling it to function in both contract and non-contract modes through type information. The same physical consumable item can be flexibly assigned to different service models by changing its type information, allowing users to switch between subscription and retail modes based on delivery availability and consumption patterns without interrupting printing service.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

There is provided a printing apparatus including: an installing part; a printer; and a controller. The printing apparatus is configured to operate in a contract mode. The consumable item includes a memory. Consumable item information includes first type information indicating that the consumable item has a first type corresponding to the contract mode or second type information indicating that the consumable item has a second type corresponding to a non-contract mode. The controller is configured to execute an information writing process of writing, in the memory, a predetermined information for treating the consumable item as the consumable item of the first type, in a case that the second type information is included in the consumable item information stored in the memory of the consumable item installed in the installing part and that the printing apparatus is required to operate in the contract mode.
