Winding Flexible Vehicle Display for Space and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices face challenges such as limited storage space, inefficient power usage, and reduced usability due to fixed installation and large size, which restricts flexibility and visibility.
Innovation Solution
A flexible display device with a retractable and extendable design, utilizing a casing, display driver, guide, and display winder, allowing the display to be wound and unwound, and featuring a POLED screen with adjustable exposure based on sensor recognition for optimized power usage and space management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display size is increased to provide more visual information, then the display functionality is improved, but the front visibility is reduced
Solution Approach 1:
The display device transitions from a fixed state to a dynamic retractable state, allowing the display to extend when needed for visibility and retract when not needed to maintain front visibility. The display unit can move between extended and retracted positions along a guide rail, enabling adaptive adjustment based on usage requirements.
Solution Approach 2:
The display is moved from a two-dimensional flat mounting on the dashboard to a three-dimensional retractable structure that can extend outward from the dashboard. This adds a depth dimension, allowing the display to be large when extended for visibility while maintaining a compact profile when retracted.
2Ease of operation
If a pop-up type mobile display is used to improve visibility, then the display accessibility is improved, but the storage space requirement increases
Solution Approach 1:
The display unit is nested within the dashboard structure when retracted, with the display housed inside a cavity in the dashboard. The connecting sheet allows the display to be stored compactly within the dashboard volume, eliminating the need for separate storage spaces while maintaining pop-up functionality.
Solution Approach 2:
The display transitions from a static stored state to a dynamic extended state through a retractable mechanism. The display can be extended on demand along a guide rail and retracted back into the dashboard, providing temporary accessibility only when needed rather than requiring permanent storage space.
3Reliability
If the entire LCD screen is operated to ensure full display functionality, then the display completeness is improved, but the power consumption increases
Solution Approach 1:
Instead of operating the entire display screen continuously, only the necessary portion of the display is extended and activated based on the specific task requirement. The display can be partially extended or fully retracted depending on whether full display functionality is needed, reducing power consumption by operating the display only when and to the extent required.
Solution Approach 2:
The display system transitions from a static fully-operational state to a dynamic state where the display can be extended or retracted based on usage requirements. This allows the system to consume power only when the display is extended and active, rather than maintaining full operational capability continuously.
4Device complexity
If a fixed display is installed to simplify the structure, then the device complexity is reduced, but the space flexibility is reduced
Solution Approach 1:
The display system incorporates a retractable mechanism with a guide rail and motor-driven actuation, transforming from a fixed static structure to a dynamic adjustable structure. This allows the display to move between retracted and extended positions, providing space flexibility while maintaining relatively simple integration with the dashboard structure.
