Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display devices used as reversible or stereoscopic image displays face issues with panel movement and division, where one panel can shift or be divided by another, leading to structural instability and potential foreign material entry.

Innovation Solution

A display device design featuring a first panel attached to a panel supporter using a first pad, a second panel attached to a cover using a second pad, and optionally a third pad for increased adhesion between panels, ensuring stable attachment and preventing movement or division.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two panels are fixed using a structure in the related art, then the display device can be manufactured as a reversible or stereoscopic image display, but one of the two panels may move or be divided by the other panel, leading to structural instability

Engineering Contradiction:

Improvereversible or stereoscopic image display capabilityVSAvoidpanel position stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The invention introduces separate pad structures (first pad and second pad) that segment the attachment function between the two panels. The first pad attaches the first panel to the panel supporter, while the second pad attaches the second panel to the cover, preventing direct contact and movement between panels while maintaining the reversible or stereoscopic display functionality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention uses pads as intermediary elements between the panels and their respective supports. The first pad acts as an intermediary between the first panel and panel supporter, and the second pad acts as an intermediary between the second panel and cover, eliminating direct panel-to-panel contact that causes movement and division

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If panels are attached using adhesive pads, then panel movement and division are prevented, but the manufacturing process becomes more complex with multiple attachment steps

Engineering Contradiction:

Improvepanel attachment stabilityVSAvoidmanufacturing process complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The invention applies adhesive pads to the panel supporter and cover in advance before attaching the panels. The first pad is formed on the panel supporter beforehand, and the second pad is formed on the cover beforehand, allowing panels to be simply placed and pressed onto the prepared adhesive surfaces, simplifying the overall attachment process despite multiple components

Inventive Principle:
