Solution Overview

Problem

Current mobile terminals lack the ability to efficiently control functions and execute voice recognition without activating the display unit, limiting user interaction in deactivated states.

Innovation Solution

A mobile terminal equipped with a sensing unit to detect taps on the display unit, allowing voice recognition functions to be executed when a predefined tap pattern is recognized, even in a deactivated state, and outputting notifications through visual, acoustic, or tactile methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display unit is activated to enable user interaction and function execution, then user interaction capability is improved, but power consumption increases

Engineering Contradiction:
Improveuser interaction capabilityVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The sensing unit detects tap patterns on the deactivated display unit before the display is activated. When a predefined tap pattern is recognized, the system prepares to execute voice recognition functions, allowing user interaction to be initiated without immediately activating the power-intensive display unit.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sensing unit acts as an intermediary between the user and the system when the display is deactivated. It detects tap gestures and triggers voice recognition functions without requiring display activation, serving as a low-power interface mediator that enables user interaction while maintaining display deactivation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If the display unit remains deactivated to reduce power consumption, then power efficiency is improved, but user interaction capability deteriorates

Engineering Contradiction:
Improvepower efficiencyVSAvoiduser interaction capability
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent replaces the traditional visual display interface (mechanical/optical system) with a gesture-based sensing interface. The sensing unit detects mechanical tap gestures on the display surface, enabling user interaction through tactile input rather than requiring visual display activation, thus maintaining power efficiency while improving interaction capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sensing unit serves multiple functions: it detects both regular touch inputs and specific tap patterns even when the display is deactivated. This multi-functionality allows the same component to enable both power-saving mode and user interaction, eliminating the need to choose between power efficiency and interaction capability.

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

3Use of energy by moving object

If voice recognition functions are executed without display activation, then power consumption is reduced, but system complexity increases due to additional sensing and pattern recognition requirements

Engineering Contradiction:
Improvepower consumptionVSAvoidsensing and pattern recognition system
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent extracts the tap pattern detection functionality from the main processing system and implements it in the sensing unit. By separating the gesture recognition function from the central processor, the system can detect predefined tap patterns and trigger voice recognition without requiring full system activation, reducing power consumption while managing complexity through functional separation.

Inventive Principle:
Principle #2Taking out (Extraction)
