Retractable Display Panel With Dual Wire-Drum Lift Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to easily embed or withdraw a display panel into or from a structure, and they do not provide a stable mechanism for raising or lowering the display panel during this process.
Innovation Solution
A display device with a cover module that includes a storage space for a display panel, a first driving system to embed and withdraw the display panel, and a second driving system to move a light blocking plate, allowing the display panel and light blocking plate to be individually or simultaneously raised or lowered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display panel is made embeddable in a structure, then space utilization and interior design are improved, but the device complexity increases due to the need for driving systems
Solution Approach 1:
The driving system is segmented into multiple independent components: a first driving system for the display panel and a second driving system for the light blocking plate. Each driving system operates independently with its own wire drum and driving wire, allowing the display panel and light blocking plate to be controlled separately or simultaneously, thus reducing the complexity of a single integrated system while maintaining embeddability.
Solution Approach 2:
The light blocking plate is nested behind the display panel, and both are nested within the cover module's storage space. The driving systems are disposed within the cover module (first driving system in front cover, second driving system in rear cover), creating a compact nested structure that enables embeddability without excessive external complexity.
2Manufacturing precision
If a light blocking plate is added to improve image clarity, then image concentration is improved, but the device complexity increases
Solution Approach 1:
The light blocking plate acts as an intermediary element positioned between the display panel and the rear cover. It can be independently controlled by the second driving system to move into or out of the storage space, providing image concentration control without requiring integration into the primary display structure, thus managing complexity while improving image clarity.
3Ease of operation
If individual control of display panel and light blocking plate is enabled, then operational flexibility is improved, but the control system complexity increases
Solution Approach 1:
The control system is segmented into two independent driving systems: the first driving system with first wire drum and first driving wire for the display panel, and the second driving system with second wire drum and second driving wire for the light blocking plate. This segmentation allows individual control of each component while keeping the control logic simple and modular, reducing overall control system complexity.

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, and a first driving system configured to embed and withdraw the display panel into and from the cover module in a first direction, wherein the first driving system includes a first wire drum and a first driving wire.
