Retractable Display Screen With Concealed Lifting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices lack effective methods for unfolding and storing display screens, leading to issues such as increased thickness, damage risk, and reduced product quality due to exposed link bars and rotating wiring boards.
Innovation Solution
A display device with a casing containing a first winding assembly, lifting assembly, and transmission assembly that controls the movement and rotation of the display screen, allowing it to be accommodated or partially/unfully unrolled, reducing exposure and improving product quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display screen is completely unrolled for dual-sided display, then the display area is increased, but the lifting assembly becomes exposed which affects product quality
Solution Approach 1:
The lifting assembly is positioned at the middle of the display screen rather than at the edge, utilizing the central spatial dimension. This allows the lifting assembly to remain concealed within the display area during unrolling, eliminating exposure while maintaining full display functionality.
Solution Approach 2:
The lifting assembly is nested within the display screen structure, specifically positioned in the middle region of the display area. This nesting allows the lifting mechanism to be hidden during operation, preventing exposure while enabling dual-sided display functionality.
2Adaptability or versatility
If the display screen is unrolled for dual-sided display, then the versatility is improved, but the risk of damage to components increases
Solution Approach 1:
A protection member is provided that contacts the non-display surface of the display screen during unrolling and winding operations. This protection member acts as a cushioning element, preventing direct contact and potential damage between the display screen and the winding shaft or other mechanical components, thereby reducing damage risk while enabling versatile display modes.
Solution Approach 2:
The protection member serves as an intermediary element between the display screen and the mechanical winding components. It mediates the interaction by providing a protective barrier, allowing the display screen to be wound and unwound without direct contact with potentially damaging surfaces, thus enhancing reliability during versatile operations.
3Adaptability or versatility
If traditional folding or rolling methods are used, then the portability is achieved, but the methods for storing display screen are limited
Solution Approach 1:
The display device employs dynamic winding and unwinding mechanisms that allow the display screen to be flexibly stored in multiple configurations. The winding shaft can rotate to wind the display screen, while the lifting assembly can dynamically adjust to lift and position the screen, creating multiple storage states beyond traditional fixed folding or rolling methods.
Solution Approach 2:
The combination of the winding shaft and lifting assembly creates a multi-functional storage system. The winding mechanism provides rolling storage, while the lifting mechanism enables alternative storage configurations. This universal system replaces the need for separate dedicated mechanisms for different storage methods, increasing versatility without proportionally increasing overall device complexity.

AI summary
The present invention discloses a display device. The display device includes a casing, a first winding assembly, a lifting assembly, a transmission assembly, and a display screen disposed in an accommodation chamber. The transmission assembly includes a fastening member at least partially disposed in the accommodation chamber. The lifting assembly is located between a first end of the display screen and a second end of the display screen. The display screen, under a first state, is received in the accommodation chamber. The display screen, under a second state, is located partially outside the accommodation chamber. The transmission assembly controls the lifting assembly to move along a first direction relative to the casing and the first winding assembly to rotate relative to the casing along a second direction to drive the display screen to move relative to the casing along the first direction.
