Solution Overview

Problem

Existing information processing devices require multiple user operations to exit a prohibited operating state, which can be cumbersome and increase operational complexity.

Innovation Solution

An information processing apparatus with a receiver for instructions to return to a home screen and a display controller that prohibits returning to the home screen during processing transitions to or from a device settings mode, ensuring seamless navigation without premature exit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the device allows returning to home screen during transition to settings mode, then user navigation flexibility is improved, but unintended exits and operational errors increase

Engineering Contradiction:

Improvenavigation flexibilityVSAvoidoperational accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary validation by checking whether the current screen state allows navigation to home screen before actually executing the navigation. This preliminary check prevents unintended exits during critical transitions, resolving the contradiction by maintaining both flexibility and reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback by monitoring the current mode state and dynamically adjusting navigation permissions based on the operational context. This feedback mechanism ensures that returning to home screen is only permitted when it will not disrupt ongoing operations, thus maintaining both user flexibility and operational reliability.

Inventive Principle:

Principle #23Feedback

2Reliability

If multiple user operations are required to exit prohibited state, then operational control is improved, but user operation complexity increases

Engineering Contradiction:

Improveoperational controlVSAvoidoperation steps

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts navigation permissions based on the current operational state. During mode transitions, the permission to return to home screen is temporarily suspended, while in stable states it is permitted. This dynamic approach maintains operational control without requiring multiple manual steps, thus reducing operational complexity while preserving reliability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system automatically manages navigation permissions based on its own operational state without requiring user intervention to adjust control parameters. The system self-regulates by enabling or disabling home screen navigation based on whether a mode transition is in progress, thereby maintaining operational control while simplifying user interaction.

Inventive Principle:

Principle #25Self-service

3Stability of the object's composition

If navigation restrictions are applied during mode transition, then operational stability is improved, but user navigation freedom decreases

Engineering Contradiction:

Improvemode transition stabilityVSAvoidnavigation freedom

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts navigation permissions based on the current operational state. During mode transitions, the permission to return to home screen is temporarily suspended to ensure stability, while in stable states it is permitted to maintain navigation freedom. This dynamic approach resolves the contradiction by adapting navigation restrictions to the operational context.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system applies preliminary restrictions on home screen navigation before a mode transition can be interrupted. By proactively preventing navigation attempts during critical transition periods, the system maintains mode transition stability while minimizing the impact on overall navigation freedom, as restrictions are applied only when necessary.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

An information processing apparatus includes: a receiver that receives an instruction to return to a home screen from a device settings screen; and a display controller that performs control in such a way that the returning to the home screen is prohibited in a case where the instruction is received by the receiver between commencement of processing to transition to a setting mode of a device and completion of the processing to transition to the setting mode, or between commencement of processing to end the setting mode of the device and completion of the processing to end the setting mode.
