Solution Overview

Problem

Mobile terminals face challenges in providing a convenient user interface for selecting menus when an external audio output device is connected, as existing solutions do not efficiently adapt to audio output operations and menu execution.

Innovation Solution

The method involves detecting an audio output device connection, converting the operation mode to a lock-up state, and displaying executable audio output-related menus, with audio signals output through the device during operation, and storing broadcasting contents when the device is disconnected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the terminal displays a multimedia menu when an earphone is connected, then the user can conveniently select multimedia applications, but the device complexity increases due to additional connection detection and menu management functions

Engineering Contradiction:
Improvemenu selection convenienceVSAvoidconnection detection and menu management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically detects earphone connection status and autonomously displays the multimedia menu without requiring user initiation. The terminal self-manages the menu display based on connection state, reducing the need for complex user interactions and manual menu management.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The multimedia menu is prepared and displayed in advance when an earphone connection is detected, before the user needs to select any application. This preliminary display action eliminates the need for subsequent menu navigation steps, simplifying the user operation while the system handles the complexity of menu preparation and display timing.

Inventive Principle:
Principle #10Preliminary action

2Use of energy by moving object

If the terminal converts to a lock-up state when no audio output device is connected, then power consumption is reduced, but the ease of operation deteriorates as users cannot quickly access audio functions

Engineering Contradiction:
Improvepower consumptionVSAvoidaudio function accessibility
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The terminal dynamically adjusts its operational state based on audio device connection status. When an audio device is connected, the system transitions from a low-power lock-up state to an active state that displays the multimedia menu, allowing quick access to audio functions. When no device is connected, the system returns to the lock-up state to conserve power, thus balancing energy efficiency with operational convenience.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the terminal displays an executable menu when an audio output device is connected, then menu execution speed is improved, but the device complexity increases due to state management requirements

Engineering Contradiction:
Improvemenu execution speedVSAvoidstate management
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The executable menu is displayed in advance upon detecting audio device connection, before the user needs to select any function. This preliminary display prepares the interface ready for immediate user interaction, eliminating delays associated with menu loading or navigation, thus improving execution speed while the system manages the connection state transitions.

Inventive Principle:
Principle #10Preliminary action
