Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display films in vehicles face instability due to vibrations during use, which affects the maintenance of the display's stabilization in the extended state.
Innovation Solution
An extendable and retractable display device with a flexible OLED display film and a flexible display film carrier, supported by an elastic intermediate layer, utilizing motor-driven length-adjustable actuators and a guide device that allows the display film and carrier to extend and retract along a radius of curvature, providing stabilization and securing the display against vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display film is used in a vehicle, then the display can be extended and retracted, but the display becomes unstable due to vibrations during driving
Solution Approach 1:
The display system is divided into multiple segments: the flexible display film, the display film carrier with upper end section and main section, the actuator, and the guide device. This segmentation allows each component to perform its specific function - the carrier provides structural support while the display film maintains flexibility, resolving the contradiction between extendability and stability
Solution Approach 2:
The display film carrier acts as an intermediary between the flexible display film and the housing/actuator system. The carrier's upper end section provides a stable attachment point for the actuator while supporting the flexible display film, enabling both movement and stabilization during extension and retraction
2Ease of operation
If the display film is made flexible for OLED technology, then the display can be stored when not in use, but it becomes susceptible to vibrations and instability
Solution Approach 1:
The patent employs a flexible display film for OLED technology that can be extended and retracted, while introducing a display film carrier with a stiffened upper end section. This carrier provides the necessary structural support and vibration resistance, allowing the flexible display film to maintain its storability while achieving reliability against vibrations
Solution Approach 2:
The system combines the flexible display film with the display film carrier made of potentially metal or stiffened material, creating a composite structure. This composite approach allows the flexible film to provide OLED functionality and storability while the carrier provides vibration resistance and reliability
3Volume of moving object
If a guide device with small radius of curvature is used, then the display can be retracted into the housing, but the structural complexity increases
Solution Approach 1:
The guide device utilizes a curved path with a radius of curvature of less than 180 degrees (preferably less than 135 or 90 degrees) to guide the display film and carrier during retraction. This curved guidance enables the display to be retracted into the housing while managing the structural complexity through optimized geometric design

AI summary
The invention relates to an extendable and retractable display device which is provided with a flexible display film (18) which is reinforced by a flexible display film support (24). The display film (18) and the display film support (24) can be moved into a housing (12) and back out of this housing (12) by being bent. This is implemented by means of at least one actuator (36), the lower end (48) of which is supported in the housing (12) and the upper end of which is connected to the upper end of the display film support (24). The housing (12) has a guide means (52) for deflecting the display film (18) and the display film support (24) when retracting and extending the display (16).
