Pivotable Support for Foldable Display Panels

Solution Overview

Problem

Existing pivotable support apparatuses for foldable display panels do not efficiently manage the transition between unfolded and folded states, leading to suboptimal support and alignment of the display panel, which affects the display's flatness and usability.

Innovation Solution

A pivotable support apparatus comprising a cladding board with rotating and sliding plates, frames, and a synchronized gear system that allows for controlled movement and alignment of the support components, ensuring a stable and flat support surface for the display panel during both unfolded and folded states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple support structure is used, then the device complexity is reduced, but the support and alignment precision deteriorates

Engineering Contradiction:

Improvesupport structure complexityVSAvoidsupport and alignment precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The support structure is divided into multiple independent components: a first support component with a first rotating plate and first sliding plate, and a second support component with a second rotating plate and second sliding plate. Each component can move independently to adjust the display panel's position and orientation, enabling precise alignment while keeping each individual component relatively simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support structure incorporates dynamic elements including rotating plates that can rotate about rotation axes and sliding plates that can slide along guide directions. These dynamic components allow the support structure to adapt to different display panel configurations (folded and unfolded states) and provide precise positioning through controlled movement rather than fixed rigid connections.

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If the support structure is made more complex to improve alignment, then the support and alignment precision improves, but the device complexity increases

Engineering Contradiction:

Improvesupport and alignment precisionVSAvoidsupport structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The support structure is divided into multiple independent components: a first support component with a first rotating plate and first sliding plate, and a second support component with a second rotating plate and second sliding plate. Each component can move independently to adjust the display panel's position and orientation, enabling precise alignment while keeping each individual component relatively simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sliding plates are positioned within or adjacent to the rotating plates, with the sliding plates moving along the rotating plates' surfaces. This nested arrangement allows the sliding mechanism to be integrated within the existing rotating plate structure rather than adding separate external components, thereby reducing overall structural complexity while maintaining precise alignment capability.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the display panel is supported in a folded state, then the portability improves, but the flatness and stability of the display surface deteriorates

Engineering Contradiction:

ImproveportabilityVSAvoiddisplay surface flatness

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The support structure incorporates dynamic elements including rotating plates that can rotate about rotation axes and sliding plates that can slide along guide directions. These dynamic components allow the support structure to adapt to different display panel configurations (folded and unfolded states) and provide precise positioning through controlled movement rather than fixed rigid connections.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The rotating plates and sliding plates act as intermediary components between the display panel and the support structure. These intermediary elements absorb and distribute the mechanical stresses and geometric transformations that occur during folding and unfolding, thereby maintaining the display panel's flatness and stability even when the overall structure is in a compact folded state.

Inventive Principle:

Principle #24Intermediary (Mediator)
