Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic devices with straight-sided touch-screen units fail to provide unique user experiences, as the scroll speed remains constant regardless of the touch location, limiting user interaction and engagement.

Innovation Solution

An electronic device with a touch-screen unit featuring curved sides, where the scroll speed changes based on the touch-scroll operation's location relative to concave or convex regions, increasing speed in parallel directions and decreasing in cross directions towards the center of concave regions, and vice versa for convex regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a touch-screen unit with straight sides is used, then the device structure is simple and easy to manufacture, but the user experience is uniform and lacks uniqueness

Engineering Contradiction:

Improvetouch-screen unit structureVSAvoiduser experience variation

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The touch-screen unit incorporates curved sides instead of straight edges, creating concave and convex regions that cause scroll speed variations based on touch location. This curvature design provides unique user experiences while maintaining manufacturing feasibility through standard curved display technologies.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

Different regions of the touch-screen unit (concave vs. convex areas) provide different scroll speed characteristics. When users touch-scroll in concave regions, the content scrolls faster, while convex regions provide slower scrolling, creating localized quality variations that enhance user interaction.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If scroll speed is constant across all touch locations, then the operation is simple and predictable, but user engagement and interaction variety are limited

Engineering Contradiction:

Improvescroll operation consistencyVSAvoiduser interaction efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The scroll speed is made dynamic rather than static, automatically adjusting based on the touch location on the curved touch-screen. The system detects whether the user is touching a concave or convex region and dynamically modifies the scroll speed accordingly, enhancing user engagement without requiring manual configuration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The touch-screen unit automatically adjusts scroll speed based on touch location without requiring user intervention or settings changes. The system self-adapts to provide different scrolling experiences based on where the user touches, making the interaction more engaging while remaining intuitive and easy to use.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If curved sides are added to the touch-screen unit, then user experience is enhanced with varying speed sensations, but the device complexity increases

Engineering Contradiction:

Improveuser experience variationVSAvoidtouch-screen unit structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

AI summary

An electronic device includes a touch-screen unit having at least one pair of facing curved sides and a body unit to which the touch-screen unit is attached. A scroll speed is changed based on the touch-scroll operation performed at respective points of the touch-screen unit relative to the at least one pair of facing curved sides.
