Flexible Display Winding Mechanism With Movable Limit Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional flexible display panels face issues with complex and costly guide structures that are prone to damage, leading to inaccurate fixing of the display panel when unwound, affecting user experience.
Innovation Solution
A flexible display device with a housing part and a winding shaft, where a flexible display part is fixed to the winding shaft, and a movable limit part is used to contact the flexible carrying part, ensuring accurate positioning and easy maintenance, with features like limit grooves, latches, and electromagnetic coils for precise movement control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex guide structure is used to fix the flexible display panel, then the panel can be positioned, but the structure becomes complicated, costly, and prone to damage
Solution Approach 1:
The guide structure is divided into a fixed guide portion attached to the housing and a movable guide portion that can slide along the winding shaft. This segmentation allows each part to perform its function independently, simplifying the overall structure while maintaining positioning accuracy.
Solution Approach 2:
A guide groove is introduced as an intermediary element that guides the flexible display panel during winding and unwinding. The groove acts as a mediator between the fixed guide portion and the flexible display panel, ensuring accurate positioning without requiring complex mechanical structures.
2Manufacturing precision
If a complex guide structure is used, then positioning can be achieved, but the cost increases
Solution Approach 1:
The guide structure is segmented into simple fixed and movable portions that can be manufactured separately and assembled, reducing overall manufacturing complexity and cost while maintaining positioning functionality.
Solution Approach 2:
The guide structure utilizes a guide groove formed in a thin guide portion rather than bulky mechanical components. This approach reduces material usage and manufacturing cost while achieving the same positioning effect.
3Manufacturing precision
If a complex guide structure is used, then the panel can be fixed, but the structure is prone to damage
Solution Approach 1:
By dividing the guide structure into fixed and movable portions, the movable portion can absorb stress and wear during winding/unwinding operations, protecting the overall structure from damage while maintaining positioning accuracy.
Solution Approach 2:
The guide portion is designed as a thin, flexible component that can deform elastically during operation, making it more resistant to damage compared to rigid complex structures. The guide groove maintains its function even under stress.
4Ease of operation
If the limit part is fixed, then the display panel can be limited, but the maintenance difficulty increases
Solution Approach 1:
The limit part is designed to be movable rather than fixed, allowing it to be easily removed and replaced for maintenance. The movable design maintains its function of limiting the flexible display panel during normal operation while enabling easy access for repair.
Solution Approach 2:
The limit part is extracted as a separate, independent component that can be removed from the housing for maintenance without disassembling the entire device. This extraction principle enables easy replacement while maintaining the limiting function during operation.
