Solution Overview

Problem

Mobile terminals with small displays face difficulties in selecting items or links on web pages and searching for information due to their compact size, making it challenging to navigate and input search commands effectively.

Innovation Solution

A mobile terminal and method that enables voice command control for searching information within a web browsing mode, allowing users to input search words, execute searches, and select results using voice commands, leveraging voice recognition technology to facilitate easier navigation and information retrieval on small screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If the mobile terminal display size is small, then the portability is improved, but the ease of selecting items or links on web pages deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidease of selecting items or links
Core Design Contradiction:
Weight of moving objectVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical input (touching, scrolling, and selecting items on the screen) with voice-based acoustic input. The voice recognition module converts spoken commands into text input, allowing users to search for and select items without physically interacting with the small display interface.

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

2Weight of moving object

If the mobile terminal display size is small, then the portability is improved, but the ease of searching for information deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidease of searching for information
Core Design Contradiction:
Weight of moving objectVSEase of operation

Solution Approach 1:

The system substitutes manual typing and navigation operations with voice-based information retrieval. Users can speak search queries naturally, and the voice recognition module processes these commands to find and display relevant information, bypassing the limitations of the small display for information searching.

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

3Device complexity

If manual input methods are used on small screens, then the device complexity is reduced, but the productivity of information retrieval deteriorates

Engineering Contradiction:
Improveinput method complexityVSAvoidinformation retrieval efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent introduces a voice recognition module that converts acoustic signals into text input, dramatically improving information retrieval productivity. Users can input search queries and commands by speaking, which is much faster and more efficient than manual typing or navigation on small screens, while the added complexity is confined to the software recognition layer.

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