Retractable Display Panel with Nested Housing for Damage Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, such as LCD and light emitting display devices, face challenges in size management and user demand satisfaction due to increased volume and the need for additional always-on-display functionality, which complicates space usage and damage prevention.
Innovation Solution
A display device with a module housing that includes a first and second moving plate, driven by belts, allowing the display panel and rear cover to be pulled up and down, enabling flexible accommodation and mode switching between always-on and normal modes, while minimizing external exposure to reduce damage risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display device volume is increased to meet user demand for larger screens, then the display area is improved, but the risk of damage to the display panel increases and more installation space is required
Solution Approach 1:
The display panel is nested within the module housing and can be retracted internally when not in use or during transport, protecting it from external damage while maintaining large display area when deployed
2Area of moving object
If the display device volume is increased to meet user demand for larger screens, then the display area is improved, but the installation space required increases
Solution Approach 1:
The display panel is designed to be movable between retracted and extended positions, allowing the installation space to be minimized when the display is not in use while providing large display area when needed
3Adaptability or versatility
If an always-on-display device is added to provide continuous display functionality, then user demand for always-on display is satisfied, but the device complexity increases
Solution Approach 1:
The module housing serves multiple functions: it protects the display panel, provides mounting structure, enables retraction mechanism, and supports both always-on-display and normal display modes through a single integrated design
4Ease of operation
If the display panel is externally exposed for normal display mode, then display functionality is improved, but the risk of damage from external factors increases
Solution Approach 1:
The display panel can dynamically change its exposure state between retracted (protected) and extended (functional) positions, allowing users to balance protection and functionality based on usage conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for efficient space usage and reduced risk of damage by enabling the display panel to be internally housed or externally extended as needed, satisfying user demands for diverse display modes without additional mounting constraints.
