Solution Overview
Problem
Existing display technologies face challenges in providing a robust and efficient support mechanism for foldable display panels that maintain a flat surface in both unfolded and folded states, ensuring optimal display performance and minimizing stress on the panel.
Innovation Solution
A pivotable support apparatus comprising a cladding board with rotating and sliding plates, frames, and a synchronized gear system that allows for a controlled angle adjustment and movement of the support plate, enabling a flat surface for the display panel in both states while accommodating the panel's foldability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple support structure is used for the foldable display panel, then the device complexity is reduced, but the ability to maintain a flat surface in both folded and unfolded states deteriorates
Solution Approach 1:
The support apparatus employs dynamic components including rotating plates that pivot between folded and unfolded states, and sliding plates that move along guide rails to adjust the support surface configuration. This dynamic structure allows the apparatus to maintain a flat support surface in both folded and unfolded states while adapting to different display panel configurations
Solution Approach 2:
The support apparatus is divided into multiple independent components: rotating plates, sliding plates, guide rails, and connecting mechanisms. Each segment performs a specific function - rotating plates provide angular adjustment, sliding plates maintain linear movement constraints, and guide rails ensure precise positioning. This segmentation allows the complex function of maintaining flatness across different states to be achieved through coordinated simple components
2Stability of the object's composition
If a robust support mechanism with multiple components is used, then the flat surface maintenance is improved, but the device complexity increases
Solution Approach 1:
The support apparatus combines multiple functions into an integrated structure where rotating plates and sliding plates work together as a unified mechanism. The rotating plates provide rotational movement while sliding plates simultaneously maintain linear constraints, and both are connected to the display panel through a unified mounting structure. This merging reduces the need for separate components for each function, achieving robust flat surface maintenance with controlled complexity
3Adaptability or versatility
If the support apparatus is designed to accommodate foldable panels, then the adaptability is improved, but the stress on the panel increases
Solution Approach 1:
The support apparatus introduces intermediary components - rotating plates and sliding plates - that act as mediators between the fixed mounting structure and the foldable display panel. These intermediaries absorb and distribute mechanical stresses, preventing direct stress concentration on the panel. The rotating plates pivot to accommodate folding movements while the sliding plates glide along guide rails, both reducing stress transmission to the panel
Solution Approach 2:
The support apparatus is designed with built-in stress-dissipating features before stress is applied to the panel. The rotating and sliding mechanisms are pre-configured to move in ways that minimize stress concentration, and the guide rails are designed with appropriate clearance and friction characteristics to cushion movements. This beforehand cushioning protects the panel from excessive stress during folding and unfolding operations
