Solution Overview

Problem

Mobile terminals with limited physical buttons require tedious and time-consuming operations to unlock and control functions, leading to low efficiency.

Innovation Solution

A method and device that allow users to execute preset program strings by pressing buttons without unlocking the screen, using a button on the headphone jack or through touch screen inputs, enabling single-click, double-click, and long-press instructions to perform various functions like camera use, audio recording, or screen operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the mobile terminal uses only a few physical buttons for control, then the device structure remains simple, but the operational efficiency decreases and the number of controllable functions is limited

Engineering Contradiction:
Improvedevice structureVSAvoidoperational efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent applies multi-functionality by enabling physical buttons to execute preset program strings that control multiple different functions. A single button press can trigger various operations including camera activation, audio recording, screenshot capture, and other applications, allowing one physical component to serve multiple purposes and thereby improving operational efficiency without adding more physical buttons.

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

2Reliability

If the touch screen is locked to prevent mistake touch, then security is improved, but the operation process becomes tedious and time-consuming

Engineering Contradiction:
ImprovesecurityVSAvoidoperation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by presetting program strings that are pre-configured to execute specific functions when triggered by physical button presses. These program strings are prepared in advance and stored in the device, allowing users to directly execute functions without needing to unlock the screen or navigate through multiple interface steps, thus saving time while maintaining security.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If multiple operations are required to execute functions (lighting screen, unlocking, selecting applications), then the control precision is improved, but the operational complexity increases

Engineering Contradiction:
Improvecontrol precisionVSAvoidoperational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies merging by combining multiple operations into a single action. Instead of requiring separate steps for lighting the screen, unlocking, and selecting applications, the system merges these operations by executing a preset program string through a single physical button press, thereby reducing operational complexity while maintaining the precision of function execution.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Embodiments of the present disclosure disclose a method and a device for executing user instructions. The method for executing user instructions includes: an instruction inputted (e.g. pressing a button or touching on a touch screen) by the user is received; a preset program or functionality is executed according to the instruction. When using the mobile terminal, the user can directly execute the preset program or functionality by pressing a button (i.e. short cut key) without unlocking the screen, the operation is simple and high accuracy, and the operational efficiency can be improved.
