Solution Overview

Problem

Existing image processing apparatuses, such as inkjet printers and copiers, face limitations in completing data processing when transitioning to a functionality-limited state due to unsatisfied service conditions, particularly when consumable supplies run low, leading to incomplete output of user-generated data.

Innovation Solution

The apparatus is equipped with functionality to save and output image data to external devices or systems, even when in a functionality-limited state, using methods like printing to a connected printer, transmitting to another device, or notifying the user of unsent data, ensuring data completion before service conditions are met.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the image processing apparatus limits functionality when service conditions are not satisfied, then the service provider can control resource usage and enforce subscription terms, but the user cannot complete processing on data already received

Engineering Contradiction:
Improveservice contract enforcementVSAvoiddata processing completion
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The apparatus performs preliminary actions by saving received image data to storage media (hard disk drive, solid state drive, or removable storage) before the functionality limited state occurs. This allows the data to be processed later when service conditions are satisfied or when offline processing is permitted.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The apparatus introduces an intermediary storage mechanism that decouples the data reception function from the data processing function. Data can be received and stored during service-compliant periods, then processed during functionality-limited periods without requiring continuous network connectivity or active service validation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the image processing apparatus requires network connectivity to verify service conditions, then the provider can manage subscription services centrally, but the user cannot access processing functions when disconnected

Engineering Contradiction:
Improveservice condition verificationVSAvoidoffline data processing
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The apparatus dynamically adjusts its operational mode based on network availability and service condition status. When connected and service conditions are met, it operates in full functionality mode. When disconnected or in functionality-limited state, it transitions to offline processing mode using previously received and stored data.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary data reception and validation while connected to the network, storing data locally so that processing can occur later without network connectivity. This separates the verification phase from the processing phase.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the apparatus completes processing before transitioning to functionality limited state, then data integrity is maintained, but processing cannot continue if service conditions change during operation

Engineering Contradiction:
Improvedata processing integrityVSAvoidprocessing continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The processing workflow is segmented into distinct phases: data reception phase, data storage phase, and data processing phase. The apparatus can complete the reception and storage phases while service conditions are satisfied, then resume or complete the processing phase later when service conditions allow, maintaining data integrity through persistent storage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The apparatus maintains continuity of useful action by preserving received data in storage media across service condition transitions. The processing action continues from where it left off, using stored data as input, ensuring that the overall workflow completes even with interruptions in service availability.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

An image processing apparatus (102) includes: a transition unit configured to transition the image processing apparatus (102) to a limited state where functionality is limited, in a case where a contract for subscription is not confirmed by the communication (201, S501, S502, S504); and a control unit configured to execute, in the limited state, processing using image data used in un-outputted processing performed before the image processing apparatus (102) transitions to the limited state (201, S701-S703).
