Flexible Display Panel Roller With Elastic Tension Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in achieving a balanced tension and height alignment between the left and right sides of a flexible display panel when it is unwound from a panel roller, ensuring a uniform display without tilting or wrinkling.
Innovation Solution
A display device with a panel roller equipped with elastic assemblies at both ends, each comprising a shaft assembly and an elastic member, which applies equal elastic forces to balance tension and maintain equal heights, while also accommodating cables through through holes to prevent friction noise and facilitate connection to external components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the flexible display panel is unwound from the panel roller, then the display unit can be deployed for viewing, but the left and right sides may have uneven tension causing tilting or height misalignment
Solution Approach 1:
The elastic assemblies function as counterbalancing mechanisms that apply elastic forces to offset the uneven tension generated during unwinding. The elastic members store and release mechanical energy to maintain force equilibrium between left and right sides, preventing the display panel from tilting or developing height differences during deployment.
Solution Approach 2:
While the overall system aims for symmetry, the elastic assemblies are positioned asymmetrically at both ends of the panel roller to specifically address the tension imbalance that occurs during unwinding. This asymmetric placement allows targeted application of counterbalancing forces where needed most during the unwinding operation.
2Stability of the object's composition
If elastic assemblies are added to both ends of the panel roller, then tension balance is improved, but the device structure becomes more complex
Solution Approach 1:
The elastic assemblies integrate multiple functions into unified structures at each end of the roller. Each assembly combines the elastic member, shaft assembly, and cable routing features into a compact integrated unit, reducing the number of separate components needed while achieving tension balance functionality.
Solution Approach 2:
The elastic assemblies serve multiple purposes: they provide counterbalancing elastic forces for tension equilibrium, serve as structural supports for the roller ends, and incorporate cable passage features for electrical connections. This multi-functionality reduces the need for additional separate components, offsetting the complexity increase from adding the assemblies themselves.
3Ease of operation
If through holes are provided in the shaft assembly, then cable connection is facilitated and friction noise is reduced, but the structural integrity may be compromised
Solution Approach 1:
The through holes are strategically positioned in specific locations on the shaft assembly where material removal has minimal impact on overall structural integrity. The holes are placed to optimize cable passage while maintaining sufficient strength in critical load-bearing regions of the shaft assembly.
