Flexible Display Length Adjustment Mechanism for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flip-type mobile communication terminals have limited display sizes, leading to inconvenient viewing experiences and touch recognition errors due to small icon sizes when trying to view images or perform touch inputs.
Innovation Solution
A mobile communication terminal with a flexible display that is continuously held in a tight state without being folded or bent, utilizing a length-adjusting assembly with a biasing member and guide grooves to adjust the display's length, allowing it to cover both upper and lower display regions and the hinge area, thereby increasing the display size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display size is increased to improve viewing experience, then the display area is improved, but the device structure becomes more complex
Solution Approach 1:
The flexible display is stored within the upper main body when not in use, with only a portion exposed at the front surface. The display can be pulled out to expand the visible area while remaining contained within the device boundaries when retracted, creating a nested configuration that increases display area without permanently increasing device size.
Solution Approach 2:
The display transitions from a static fixed-size configuration to a dynamic adjustable configuration. Users can pull the flexible display to expand it for viewing and then retract it using the length-adjusting assembly, allowing the display area to change based on usage needs while maintaining a compact form when not in use.
2Measurement precision
If the display size is increased to reduce touch recognition errors, then the icon size is improved, but the device structure becomes more complex
Solution Approach 1:
The flexible display with larger area is stored within the upper main body when not in use. When users need to perform touch operations, they can pull the display to expand it, providing larger icons and better touch recognition accuracy only when needed, while maintaining a compact structure during storage.
Solution Approach 2:
The display area dynamically adjusts based on operational requirements. During touch operations, the expanded display provides larger icons for accurate recognition, while during storage or non-use periods, the display retracts to maintain device portability without permanently increasing size.
3Area of moving object
If the flexible display is allowed to fold or bend to adjust length, then the display area is improved, but the display quality deteriorates
Solution Approach 1:
The display transitions from a static fixed configuration to a dynamic adjustable configuration through pulling and retracting mechanisms rather than folding. The flexible display is pulled horizontally to expand the visible area and then automatically retracts using the biasing member, eliminating repeated folding and bending that would degrade display quality over time.
Solution Approach 2:
The length-adjusting assembly with guide grooves and biasing member acts as an intermediary mechanism between the flexible display and the housing. This mechanism controls the display's movement through horizontal pulling and automatic retraction, preventing direct folding and bending of the display while still allowing area adjustment.
