Flexible Vehicle Display Layout With Pantograph-Guided Curving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular display devices require the device main body and adjustment mechanism to be aligned in the front-rear direction for effective screen orientation, limiting space utilization and flexibility within the vehicle.
Innovation Solution
A display device with a flexible sheet-like display and a pantograph-type movement mechanism that allows the display to be unfolded and housed in directions intersecting the front-rear axis, utilizing a guide mechanism to curve and support the display, reducing the required space and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device main body and adjustment device are arranged side by side in the front-rear direction to adjust the screen orientation, then the screen can be oriented to the occupant side, but the occupied space in the vehicle increases
Solution Approach 1:
The patent combines the device main body and adjustment device into an integrated structure where the adjustment device is positioned at the front end of the device main body rather than side by side. This merging of functions allows the display to be curved and oriented while reducing the overall space occupied in the vehicle's front-rear direction.
Solution Approach 2:
The patent introduces a guide mechanism that guides the rear end of the display in a direction different from the movement direction of the connection (left-right direction versus front-rear direction). This dimensional change allows the display to be oriented to the occupant side while the mechanisms occupy less linear space along the front-rear axis.
2Volume of moving object
If the connection moves in a direction intersecting the front-rear direction and the guide mechanism guides the second end portion in a different guide direction, then the display can be unfolded in a compact configuration, but the device complexity increases
Solution Approach 1:
The patent divides the display mechanism into distinct functional segments: a connection that moves in the front-rear direction to unfold/house the display, and a guide mechanism that guides the rear end in a perpendicular direction for orientation. This segmentation allows each component to perform its specific function efficiently while maintaining overall system compactness.
Solution Approach 2:
The patent employs dynamic movement where the connection and guide mechanism work cooperatively - the connection moves the display in the front-rear direction while the guide mechanism simultaneously or sequentially guides the rear end in a perpendicular direction. This dynamic coordination enables compact folding/unfolding while managing structural complexity through controlled motion sequences.

AI summary
Provided is a display device provided inside a vehicle. The display device includes: a display having flexibility and a sheet shape; a movement mechanism that includes a connection connected to a first end portion of the display and in which the connection moves in a direction intersecting a front-rear direction of the vehicle; and a guide mechanism configured to guide a second end portion of the display in a guide direction different from a movement direction of the connection in association with movement of the connection while curving and supporting a part of the display.
