Solution Overview

Problem

Conventional mobile terminals scroll all information items at the same speed, making it difficult for users to distinguish the importance of different items based on their scrolling speed.

Innovation Solution

A mobile terminal with a touchscreen and controller that allows for different scroll speeds for various groups of items, enabling users to recognize importance through varying scroll speeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all information items are scrolled at the same scroll speed, then the scrolling operation is simple and uniform, but the user cannot distinguish the importance of different information items

Engineering Contradiction:
Improveinformation importance recognitionVSAvoidscroll speed control complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent divides information items into multiple groups based on importance levels. Each group is assigned a different scroll speed, allowing users to distinguish important items (slower scroll speed) from less important items (faster scroll speed). This segmentation resolves the contradiction by enabling information differentiation without requiring complex manual control for each individual item.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different scroll speeds to different local regions (groups of items) based on their importance. Important information items are assigned a first scroll speed while less important items are assigned a second scroll speed, creating local quality variations that help users quickly identify important information during scrolling.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If different scroll speeds are applied to different groups of items, then user recognition of information importance is enhanced, but the control mechanism becomes more complex

Engineering Contradiction:
Improveinformation recognition easeVSAvoidscroll control mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically assigns items to different groups and applies appropriate scroll speeds based on predefined importance criteria. The controller automatically determines which items should scroll at the first speed versus the second speed without requiring users to manually configure each item's scroll behavior, thereby maintaining ease of operation while achieving differentiated information recognition.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the scroll speed parameter dynamically based on the importance level of different information item groups. By adjusting this single parameter (scroll speed) according to item importance, the system enhances information recognition without introducing multiple complex control mechanisms.

Inventive Principle:
Principle #35Parameter changes
