Retractable Display Panel Lift With Controlled Lowering Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to embed or withdraw display panels seamlessly and stably into structures, limiting their integration with furniture, appliances, and facilities while maintaining clear image display.
Innovation Solution
A display device with a cover module, a first driving system for embedding or withdrawing the display panel, and a first elevation assistance system to control the speed of raising and lowering the panel, allowing for simplified and stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display panel is coupled to structures such as furniture, appliances, and facilities, then space utilization and interior design are improved, but the ability to seamlessly embed or withdraw the display panel is limited
Solution Approach 1:
The display panel is designed with movable capabilities, allowing it to transition between embedded and withdrawn states. The driving system enables dynamic repositioning of the display panel along the first direction, transforming a static coupled structure into a dynamic one that can adapt to different usage scenarios.
Solution Approach 2:
The coupling system is divided into separate functional components: a driving system for movement, an elevation assistance system for speed control, and a cover module for housing. This segmentation allows each component to be optimized independently while working together to achieve seamless embedding and withdrawing operations.
2Ease of operation
If the display panel is raised or lowered during embedding or withdrawing, then the operation is simplified, but the stability of the panel movement is reduced
Solution Approach 1:
The elevation assistance system acts as a counterbalancing mechanism that opposes the gravitational force on the display panel. By providing upward support force, it reduces the net weight effect during movement, allowing the panel to be raised and lowered more easily while maintaining stable, controlled motion through the storage space.
Solution Approach 2:
The elevation assistance system serves as an intermediary between the driving system and the display panel. It mediates the movement by controlling the lowering speed and providing support, ensuring that the panel moves smoothly and stably through the storage space without uncontrolled acceleration or instability.
3Productivity
If the display panel is embedded or withdrawn rapidly, then productivity is improved, but image clarity and display quality deteriorate
Solution Approach 1:
The elevation assistance system implements periodic or phased control of the panel movement. During embedding or withdrawing, it first allows rapid movement through most of the storage space, then provides controlled deceleration near the endpoints. This periodic action pattern enables high overall productivity while maintaining image quality by preventing rapid movement during critical display positions.

AI summary
A display device includes a cover module having a storage space therein, a display panel configured to be at least partially disposed inside the storage space or withdrawn outside the storage space, a first driving system configured to embed the display panel into the cover module or withdraw the display panel from the cover module in a first direction, and a first elevation assistance system disposed inside the storage space and configured to control a speed of raising and lowering the display panel.
