Rotating Dashboard Screen Mount for Driver-Passenger Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road vehicle display systems, particularly in high-performance vehicles, face challenges in providing optimal viewing for both the driver and passenger without causing distraction, especially during sports driving, and limit passenger entertainment due to the integration of central screens that are difficult to view without obstructing the driver's focus.
Innovation Solution
A content display device with a hinged support element and movement system that allows the screen to rotate and translate, enabling it to be oriented towards either the driver or passenger, with mechanical controls and locking mechanisms to prevent sudden movements during vehicle dynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the central screen is integral with the dashboard and fixed in position, then the driver can view vehicle information, but the passenger cannot view distracting content without distracting the driver
Solution Approach 1:
The screen is made movable through a hinged support element that allows rotation between a first position (facing driver) and a second position (facing passenger). This dynamic positioning enables the same screen to serve different functions for different users without requiring multiple fixed screens.
Solution Approach 2:
The support structure is divided into separable components: a dashboard-mounted base and a hinged support element that can be attached and detached. This segmentation allows flexible installation and repositioning while maintaining structural integrity.
2Adaptability or versatility
If the screen is made movable to face passenger, then passenger entertainment is improved, but driver safety may be compromised due to sudden movements during vehicle dynamics
Solution Approach 1:
A rubber band is used as a flexible elastic element to provide continuous tension on the hinged support element. This elastic constraint prevents sudden or excessive movements of the screen during vehicle acceleration, braking, or cornering, while still allowing controlled repositioning between driver-facing and passenger-facing orientations.
Solution Approach 2:
The rubber band applies pre-tension to the hinged support element before any movement occurs, creating a restoring force that cushions against unintended movements. This elastic cushioning ensures the screen remains stable during normal vehicle operations while still being repositionable when needed.
3Ease of operation
If touch controls are used on the central screen, then control functionality is simplified, but driver distraction increases during sports car driving
Solution Approach 1:
Physical control buttons are extracted from the screen assembly and placed on a separate manipulation element that can be positioned within easy reach of the driver. This separation allows the driver to control screen functions without touching the screen itself, reducing distraction while maintaining ease of operation.
4Ease of operation
If the screen is positioned for optimal driver viewing, then driver information access is improved, but passenger viewing of distracting content becomes difficult
Solution Approach 1:
The hinged support element enables the screen to dynamically switch between two primary viewing orientations: facing the driver for vehicle information access and facing the passenger for entertainment content. This dynamic repositioning allows the system to adapt to different user needs without compromising either function.

AI summary
A content display device for a road vehicle; the content display device comprising a support element configured to be mounted centrally at a dashboard of the road vehicle; at least one screen, mechanically connected to the support element and configured to be visible to a passenger and/or a driver while driving; a movement system hinged to the support element and hingeble to the dashboard for alternately rotating the screen towards the driver and/or towards the passenger.
