Rotatable Projection Unit for Vehicular Infotainment Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicular infotainment systems often have display screens installed without consideration for the driver's eye point, leading to inconvenient interaction and reduced visibility, especially in larger vehicles, and do not provide equal benefits to both drivers and passengers.
Innovation Solution
A vehicular infotainment apparatus with a rotatable and movable projection unit that adjusts the display screen's orientation and content based on the driver's rotation angle, allowing for improved visibility and touch input accessibility by projecting the screen towards the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the infotainment apparatus is installed based on the driver's viewing angle to improve visibility and touch input accessibility, then driver convenience is improved, but the same benefits are not provided to front and rear passengers
Solution Approach 1:
The projection unit is made rotatable and movable rather than fixed, allowing it to dynamically adjust its orientation and position. This enables the display to be redirected toward different seating positions (driver, front passenger, rear passengers) based on who needs to view or interact with the interface, thereby resolving the contradiction between optimizing for driver convenience and providing accessibility to passengers.
Solution Approach 2:
The projection unit is designed to serve multiple functions and multiple users. By making the projection unit rotatable and movable, a single display system can serve the driver, front passenger, and rear passengers, transforming a driver-specific interface into a universal interface that adapts to different users' needs and positions.
2Ease of manufacture
If the display screen is installed without consideration of the driver's eye point, then installation simplicity is maintained, but visibility and interaction convenience are reduced
Solution Approach 1:
Rather than installing multiple fixed displays at different positions, the system uses a single projection unit that can dynamically adjust its orientation. This maintains installation simplicity while achieving proper alignment with the driver's eye point and other seating positions through rotation and movement, rather than through complex multi-display installation.
Solution Approach 2:
The projection unit can automatically or manually adjust its own orientation to align with the driver's eye point or other desired viewing positions. This self-adjustment capability eliminates the need for precise manual installation positioning, maintaining ease of installation while ensuring optimal visibility and interaction convenience.

AI summary
A vehicular infotainment apparatus may include: a display unit configured to display information on a screen; a projection unit disposed proximate to the screen of the display unit, the projection unit being rotatable, movable, and configured to project the information displayed on the screen of the display unit; a driver configured to rotate and move the projection unit; and a controller configured to control operation of the display unit and the driver and to receive a request for rotation of the projection unit. The controller may be further configured to control the driver such that the driver causes the projection unit to rotate or move at a rotation angle corresponding to the request for rotation of the projection unit and to control the display unit such that the display unit modifies the information displayed on the screen of the display unit according to the rotation angle.
