Flexible Vehicle Display Retraction With Controlled Screen Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices face challenges in minimizing accommodation space, efficiently retracting and extending displays, controlling display exposure, and optimizing power usage based on display needs.
Innovation Solution
A flexible display device with a sensor recognizer to detect the rotation state of a rotary drum, a display driver with motor-controlled arms for movement, and a guide part to manage curvature, allowing controlled exposure and retraction of a POLED display using a worm gear mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed display is installed in a vehicle, then the display can be positioned at a specific location, but the utilization of space in the vehicle is limited
Solution Approach 1:
The display device transitions from a fixed position to a movable position through a guide mechanism that allows the display to move up and down or left and right relative to the dashboard, enabling flexible space utilization while maintaining a relatively simple structure
Solution Approach 2:
The display system is divided into a display unit and a separate accommodation space unit, allowing the display to be stored when not in use and deployed when needed, thereby improving space utilization without requiring complex integration throughout the vehicle interior
2Adaptability or versatility
If a pop-up style movable display is used, then the display can be stored and extended when necessary, but a separate accommodation space is required which limits space utilization
Solution Approach 1:
The display device is nested within the dashboard structure itself, where the display unit can be accommodated within the dashboard's existing volume. The guide mechanism allows the display to move within the dashboard boundaries, eliminating the need for separate external accommodation spaces while maintaining mobility
3Productivity
If an entire LCD screen is operated, then the display can show information, but power inefficiency occurs when the display is not fully exposed
Solution Approach 1:
Instead of operating the entire display screen continuously, the system activates only the necessary portion of the display based on the current operational context. The guide mechanism enables selective exposure of the display, and the control system activates only the required display area, reducing power consumption while maintaining full functionality when needed
Applied Scientific Principles
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 device reduces accommodation space, efficiently adjusts display exposure, and optimizes power usage by controlling the display's degree of extension and retraction, enhancing usability and efficiency.
Implementation Method 1
a display part to be retracted or extended into or out of the casing, the display part including a POLED
