Solution Overview

Problem

Existing mobile phone applications with dynamic display effects, such as dynamic wallpaper, are not interactive and require a touch screen to change, which increases costs and thickness, and may not provide sufficient entertainment when triggered through touch screen inputs.

Innovation Solution

A method and device that allow dynamic display effects to be changed and adjusted through voice control by recording and analyzing user voice energy, calculating a changing rate, and applying it to the application display, enabling voice-controlled interaction without a touch screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a touch screen is added to enable dynamic display effect changes, then the interaction capability is improved, but the cost and thickness of the mobile phone increase

Engineering Contradiction:

Improveinteraction capabilityVSAvoidcost and thickness

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical touch screen input system with a voice-based acoustic input system. The microphone captures voice signals, which are then processed to control dynamic display effects, eliminating the need for a touch screen while maintaining interaction capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces voice signals as an intermediary between the user and the dynamic display system. Instead of direct touch screen contact, the user's voice serves as the mediating input method to trigger and control display effect changes.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a touch screen is used to trigger dynamic wallpaper changes, then the display effect can be changed, but the user experience lacks interestingness and entertainment

Engineering Contradiction:

Improvedisplay effect change capabilityVSAvoiduser experience interestingness

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent changes the input parameter from tactile (touch screen pressure and position) to acoustic (voice volume and characteristics). This parameter change enables more diverse and interesting interaction modes, such as using different shouting volumes to control the speed or intensity of dynamic effects.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces dynamic voice-based control that allows real-time adjustment of display effects during operation. Users can dynamically change display behavior through varying their voice input, creating a more engaging and entertaining experience compared to static touch screen interactions.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If voice control is implemented, then the need for a touch screen is eliminated reducing cost and thickness, but a new interaction method must be established

Engineering Contradiction:

Improvehardware requirementsVSAvoidinteraction method establishment

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent makes the voice recognition system multi-functional by using it not only for basic display effect triggering but also for controlling various parameters such as changing rates and different display modes. This universal approach eliminates the need for multiple specialized input devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)
