Solution Overview

Problem

Existing mobile phones require users to manually disable the wireless communication function for all applications when entering sensitive environments like hospitals or airplanes, which is inconvenient as it involves turning off the phone, and users need to recognize which applications can be used without wireless communication.

Innovation Solution

An electronic apparatus with a display unit showing application identification information in a list format, allowing users to selectively disable the wireless communication function for specific applications, using a setting unit to manage whether the wireless communication unit is activated for each application, and displaying icons indicating the status of wireless communication activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the wireless communication function is disabled for all applications, then radio wave interference with other electronic devices is prevented, but user convenience deteriorates as users cannot access applications that do not require wireless communication

Engineering Contradiction:
Improveradio wave interferenceVSAvoiduser convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent segments the wireless communication function control by application, allowing each application to have independent wireless communication activation status. This enables users to disable wireless communication only for specific applications that do not require it, while keeping it enabled for other applications, thus preventing radio wave interference for non-communication apps while maintaining user access to communication-dependent apps.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic control of the wireless communication function based on the currently executed application. The system automatically adjusts the wireless communication activation status according to which application is running, providing adaptive behavior that prevents interference when appropriate while maintaining functionality when needed, thereby improving user convenience without manual intervention.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the wireless communication function is disabled application by application, then user convenience is improved by allowing access to non-communication apps, but device complexity increases due to additional control mechanisms

Engineering Contradiction:
Improveuser convenienceVSAvoidcontrol mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements automatic determination of wireless communication activation status based on the currently executed application. The system self-adjusts the wireless communication function without requiring manual user configuration, using pre-stored application information that indicates whether each application requires wireless communication. This automation reduces the perceived complexity for users while maintaining the sophisticated application-specific control capability.

Inventive Principle:
Principle #25Self-service

3Reliability

If manual configuration of wireless communication settings is required for each application, then precise control is achieved, but time consumption increases as users must recognize which applications can be used

Engineering Contradiction:
Improvecontrol precisionVSAvoidtime consumption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary configuration by storing in advance, for each application, information indicating whether wireless communication should be activated. This pre-stored application information is prepared beforehand and automatically referenced when an application is executed, eliminating the need for users to manually configure settings each time and reducing time consumption while maintaining precise control.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent provides visual feedback by displaying setting identification information on the application list that indicates the wireless communication activation status for each application. This feedback mechanism helps users quickly identify which applications have wireless communication disabled without requiring them to manually check or remember, thereby reducing time consumption while maintaining control precision.

Inventive Principle:
Principle #23Feedback

AI summary

An electronic apparatus, such as a mobile phone, that has a plurality of applications, displays an icon menu listing icons corresponding to the plurality of applications on its display section. The electronic apparatus stores an application operation setting table, which stores, for each of the plurality of applications, setting information regarding whether or not an RF block is to be driven in parallel with execution of the application. When displaying the icon menu, the electronic apparatus displays an icon corresponding to an application which is set not to drive the RF block in parallel with execution of it, by adding an icon indicating that the RF block is not to be driven, based on the setting information stored in the application operation setting table or setting information input from an input section.
