Telescopic Bar Supports Flat Retractible Display Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack stability and flexibility in their design, particularly when transitioning between states, which can lead to mechanical stress and reduced user immersion due to uneven display surfaces.
Innovation Solution
A display device featuring a telescopic bar that supports the back of the display portion, allowing it to remain flat, combined with a controller that manages the display's speed and position adjustments, including a magnetic bottom bar for secure attachment and a flexible module cover for shock absorption, and an indicator for user feedback on screen ratio changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display portion is made flexible and retractable, then the device portability and space efficiency are improved, but the display surface flatness and structural stability deteriorate
Solution Approach 1:
The support structure is divided into multiple telescopic bar segments that can extend and contract independently. These segmented bars work together to maintain the display portion's flatness during extension while allowing retraction for portability.
Solution Approach 2:
The telescopic bar acts as an intermediary component between the retractable display portion and the housing. It mediates the transition between retracted and extended states while maintaining structural stability and surface flatness during the transition.
2Productivity
If the display portion is extended quickly, then the productivity and response time are improved, but the mechanical stress and potential damage increase
Solution Approach 1:
The extension process is divided into periodic phases with different speeds. The controller implements a two-stage extension: a first faster speed for the majority of the extension, and a second slower speed near the end, creating a periodic velocity profile that reduces mechanical stress.
Solution Approach 2:
The system prepares for potential mechanical stress by implementing speed reduction before the display portion fully extends. The controller detects near-complete extension and proactively reduces speed to prevent excessive mechanical stress and potential damage.
3Stability of the object's composition
If the telescopic bar is made rigid to maintain flatness, then the display surface stability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The telescopic bar employs a nested structure where multiple bar segments are inserted within each other. This nesting allows the rigid support structure to extend and contract while maintaining flatness, without requiring an overly complex external mechanism.
4Manufacturing precision
If the display area is fixed in position, then the manufacturing precision and assembly ease are improved, but the adaptability and user customization options decrease
Solution Approach 1:
The display area position is made dynamic rather than fixed. The controller can adjust the display area's position within the display portion based on user input or detected screen ratios, allowing adaptation to different viewing preferences and applications while maintaining manufacturing precision through controlled movement.

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 provides enhanced stability and user immersion by maintaining a flat display surface, reducing mechanical stress, and improving the user experience through controlled speed transitions and secure attachment, while also allowing for flexible positioning of the display area.

AI summary
A display device is disclosed. The display device includes: a housing; at least one roller configured to be positioned within the housing; a display portion including a display panel and a module cover; and a telescopic bar, one end of which is fixed to the interior of the housing and the other end is fixed to the bottom end of the display portion, wherein the display panel and the module cover are either in a first state where the display panel and the module cover are kept wound around the at least one roller or in a second state where the display panel and the module cover are kept unwound from the at least one roller, in contact with each other, and exposed out of the housing. The telescopic bar supports the back of a display portion in conjunction with the display portion, thereby allowing the display portion to remain flat.
