Pivoting Vehicle Display Structure for Expandable Screen Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices are limited in their ability to provide a large screen size and variable display mechanisms, which hinders the efficient presentation of diverse information to drivers and passengers.
Innovation Solution
A display device for vehicles featuring an elongated housing with a pivotally coupled display base and a display module that includes a first and second display surface, where the second surface is bent and extends from the first, allowing for rotation and expansion to a larger screen through a driving module comprising pulleys and motors.

Engineering Contradiction Analysis
1Area of moving object
If a traditional fixed display device is used in a vehicle, then the structure is simple and easy to manufacture, but the display size is limited and cannot be expanded to provide large screen information
Solution Approach 1:
The display device employs a dynamic expansion mechanism where the display base can pivot from a retracted position to an extended position, transforming the display from a fixed small screen to a large expandable screen. This dynamic structure allows the display area to change based on operational requirements while maintaining a compact form when not in use.
Solution Approach 2:
The display base is designed to be nested within the housing when in the retracted state, similar to a nested doll structure. The display module can be stored within the housing confines and deployed outward when needed, maximizing space utilization and enabling large screen display without permanently occupying excessive space.
2Adaptability or versatility
If a variable display mechanism is implemented, then the display can be expanded to large screen, but the structure becomes complex with multiple components
Solution Approach 1:
The display device integrates multiple functions into a single system: the display base serves both as a structural support and a pivotable mounting platform; the housing provides both protection and a guide for the pivot motion; and the display module itself can be rotated to different angles. This multi-functionality reduces the need for separate components for each function.
Solution Approach 2:
The display system is segmented into distinct functional modules: the housing, the pivotally coupled display base, and the display module. This segmentation allows each component to be optimized independently while maintaining overall system simplicity. The modular design facilitates easier manufacturing and assembly despite the variable configuration capability.
3Length of moving object
If the display base is pivotally coupled to enable rotation, then the display can be expanded and repositioned, but the mechanism requires additional driving components
Solution Approach 1:
The pivotally coupled display base enables dynamic repositioning along a rotational arc, allowing the display to extend outward and then retract back into the housing. This dynamic motion path is achieved through the pivotal connection that permits rotation while maintaining structural integrity throughout the movement range.
