Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face difficulty in accessing notifications displayed near the upper edge of touch screen devices when operating them with one hand, as existing interfaces do not adapt to individual user preferences or hand orientations.

Innovation Solution

An electronic device with a controller that identifies a user-preferred region based on detected orientation, hand position, and interaction patterns, allowing GUI elements to be dynamically displayed within a reachable area, including edge displays when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If notifications are displayed near the upper edge of the screen, then the display can show all notifications, but users experience difficulty reaching them when holding the device with one hand

Engineering Contradiction:

Improvedisplay area utilizationVSAvoidone-handed accessibility

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the notification display position adaptive rather than fixed. The controller dynamically adjusts the notification display region based on detected hand orientation and user interaction patterns, allowing the interface to move between upper edge and other accessible regions depending on how the user holds the device

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of display position from a static upper edge location to a dynamic location determined by hand orientation detection. The controller modifies the notification display region coordinates based on detected orientation parameters and user preference data

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If icons are displayed according to a curved surface near a corner of a screen, then one-handed accessibility is improved, but individual users with different hand features still experience inconvenience

Engineering Contradiction:

Improveone-handed accessibilityVSAvoidindividual user adaptation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements feedback by monitoring user interactions with the display and using this information to identify preferred display regions. The controller continuously observes touch patterns and interaction frequency to determine which regions users access most often, then adapts the notification display location accordingly

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by proactively detecting hand orientation and predicting user preference before the user explicitly requests a change. The controller pre-adjusts the notification display region based on detected orientation and historical interaction data, preparing the interface in advance for optimal accessibility

Inventive Principle:

Principle #10Preliminary action
