Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users cannot maintain a focused gaze when viewing content on display devices that require rotation, as the content and display rotate together, disrupting the viewing experience.

Innovation Solution

A method and device that control a rotatable display to maintain the orientation of content elements opposite to the display's rotation direction, ensuring the content appears stationary while the display rotates, using a processor to manage the rotation and fading of elements to maintain focus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display is rotated to accommodate horizontal or vertical content, then the display can show content in the correct orientation, but the content and display rotate together causing the user's gaze to shift and cannot maintain focused viewing

Engineering Contradiction:

Improvedisplay orientation adaptabilityVSAvoidviewing experience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display system is segmented into two independent rotational components: the display panel rotation and the content element rotation. The display can rotate to accommodate different content orientations while the content elements rotate independently in the opposite direction to maintain their visual orientation relative to the user, thereby resolving the contradiction between display adaptability and viewing comfort

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of rotating the content with the display, the invention applies inverse rotation by rotating the content elements in the opposite direction to the display rotation. This inversion allows the display to adapt to different content orientations while the content elements maintain their original orientation, solving the gaze shift problem

Inventive Principle:

Principle #13The other way round (Inversion)

2Stability of the object's composition

If the content elements are rotated with the display, then the content orientation matches the display orientation, but the user cannot maintain a focused gaze on the content

Engineering Contradiction:

Improvecontent orientation stabilityVSAvoiduser gaze stability

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The invention applies inverse rotation by rotating the content elements in the opposite direction to the display rotation. When the display rotates clockwise, the content elements rotate counter-clockwise by the same angle, maintaining their visual orientation relative to the user and ensuring gaze stability

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The system dynamically adjusts the rotation of content elements based on the display rotation state. The content elements are rotated in real-time opposite to the display rotation, creating a dynamic compensation mechanism that maintains content orientation stability relative to the user while allowing display rotation flexibility

Inventive Principle:

Principle #15Dynamics
