Solution Overview

Problem

Existing image forming apparatuses in flat-rate services face challenges in seamlessly transitioning from a contracted state to a purchased state, leading to functional restrictions and inefficiencies in user experience.

Innovation Solution

The image forming apparatus is equipped with a processor and memory to acquire and store subscription service contract information, allowing it to dynamically switch states based on contract updates, enabling or disabling functions accordingly, and notifying users of changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the image forming apparatus maintains functional restrictions after contract cancellation, then the service provider can protect subscription business model, but the user experience deteriorates and full functionality cannot be accessed post-purchase

Engineering Contradiction:
Improveservice model protectionVSAvoiduser experience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements dynamic state transitions in the image forming apparatus by detecting contract cancellation information and automatically changing the device state from a restricted subscription mode to a full-functionality purchased mode. The control unit monitors contract status and dynamically adjusts functional restrictions based on the current state, ensuring seamless transition that benefits the user while maintaining service model integrity.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the image forming apparatus requires manual configuration after contract cancellation, then system complexity is reduced, but transition time increases and productivity decreases

Engineering Contradiction:
Improvesystem complexityVSAvoidtransition time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring the image forming apparatus with the capability to automatically detect contract cancellation information and initiate state transitions without user intervention. The control unit is pre-programmed to monitor contract status and automatically execute the transition to purchased state, eliminating manual configuration steps and reducing transition time while maintaining manageable system complexity.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If the image forming apparatus automatically transitions states upon contract cancellation, then productivity improves and user experience enhances, but device complexity increases

Engineering Contradiction:
Improvetransition efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements universality by designing the control unit to perform multiple functions: monitoring contract information, detecting cancellation status, determining current device state, and executing state transitions. This multi-functional approach consolidates what could be separate complex systems into a single integrated control mechanism, improving transition efficiency while managing overall device complexity through functional integration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An image forming apparatus includes: an acquisition unit that acquires information concerning a contract of a subscription service of the image forming apparatus; a storage unit that stores the information concerning the contract of the subscription service acquired by the acquisition unit; and a control unit that sets, based on a fact that the information concerning the contract of the subscription service stored in the storage unit is first information indicating purchase of the image forming apparatus, a state of the image forming apparatus to a state corresponding to the first information.
