Dashboard Display Lock Release for Manual Vehicle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices in motor vehicles face challenges in adjusting to an individually optimal viewing position for users, often requiring complex motorized drives or universal presetting.
Innovation Solution
A manually adjustable display with a locking arrangement that can be transferred into a release state via a motorized mechanism, allowing users to manually adjust the display into an individually advantageous position, secured by a flexible force transmission element and a resetting device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motorized drive is used to adjust the display, then the display can be moved into functional positions, but the structure becomes complicated and individual adaptation is difficult
Solution Approach 1:
The adjustment mechanism is segmented into two independent parts: a motorized locking arrangement that handles positioning and a manual adjustment mechanism that handles fine-tuning. This segmentation allows the motorized part to provide stable positioning while the manual part enables simple individual adaptation without complex integrated controls
Solution Approach 2:
The locking arrangement can be dynamically transferred between a locked state (holding the display firmly) and an unlocked state (allowing manual adjustment). This dynamic state change enables the system to switch between stable positioning and flexible adjustment modes, resolving the contradiction between firm holding and easy repositioning
2Reliability
If a locking arrangement exerts holding force, then the display is securely positioned, but manual adjustment becomes difficult
Solution Approach 1:
The locking arrangement's holding force is dynamically controlled through state transfer. When unlocked, the holding force is reduced or eliminated to allow easy manual adjustment. When locked, the holding force is maximized to secure the display position. This dynamic control resolves the contradiction between secure positioning and ease of adjustment
Solution Approach 2:
The motorized locking arrangement is transferred to the unlocked state in advance before manual adjustment is needed. This preliminary action removes the holding force barrier beforehand, making manual adjustment effortless. After adjustment, the locking arrangement is transferred to the locked state to secure the new position

AI summary
Various embodiments relate to a display device in a motor vehicle, in particular arranged on a dashboard, having an adjustable display and an adjustment mechanism assigned to the display, wherein the display is adjustable between a parked position and at least one functional position. It is proposed that the adjustment mechanism has a locking arrangement which can be moved from a locking state, in which the locking arrangement exerts a holding force on the adjustment mechanism for holding the display in the parked position and/or the functional position, and possibly also in an intermediate position, into a release state, in which the locking arrangement does not exert a holding force, or exerts a reduced holding force, on the adjustment mechanism, that the display is manually adjustable, and that the locking arrangement can be transferred into the release state in a motorized manner.
