Vehicle Display Panel Position and Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems in vehicles often have fixed installation positions and angles that do not suit the user's preferences for optimal visibility and operability, especially when displaying vertically-long images, as the display panel's position and angle are determined by interior design rather than user convenience.
Innovation Solution
A display system incorporating a linearly-moving mechanism, a right-and-left changing mechanism, an up-and-down changing mechanism, and a rotation mechanism that allow the display panel to be adjusted in position and angle, enabling users to customize its orientation for better visibility and operability, with mechanisms designed to stack and reduce weight for easier movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is installed in a predetermined installation area determined by interior design, then the interior design requirements are satisfied, but the position and angle of the display panel are not suitable for the user to see and operate
Solution Approach 1:
The display panel is equipped with multiple adjustment mechanisms including a linearly-moving mechanism for positional adjustment, a right-and-left changing mechanism for horizontal angular adjustment, an up-and-down changing mechanism for vertical angular adjustment, and a rotation mechanism for rotational adjustment. These dynamic mechanisms enable the display panel to transition from a fixed installation state to multiple adjustable states, resolving the contradiction between satisfying fixed installation requirements and adapting to user viewing needs.
Solution Approach 2:
The adjustment system is divided into four independent mechanisms: linear movement for position, right-and-left changing for horizontal angle, up-and-down changing for vertical angle, and rotation for orientation. Each mechanism handles a specific degree of freedom, allowing complex positioning to be achieved through coordinated operation of simpler subsystems, thus managing device complexity while providing comprehensive adaptability.
2Adaptability or versatility
If multiple mechanisms are provided to move the display panel in various directions, then the position and angle can be adjusted as desired, but the weight of the movement apparatus increases
Solution Approach 1:
The linearly-moving mechanism, right-and-left changing mechanism, up-and-down changing mechanism, and rotation mechanism are integrated into a unified adjustment system where mechanisms share common structural elements and mounting interfaces. This merging approach allows the mechanisms to support each other structurally, distributing the weight load and reducing the overall weight of the movement apparatus compared to having completely separate mechanisms.
3Weight of moving object
If mechanisms are stacked on top of each other to reduce weight, then the weight of the movement apparatus is reduced, but the fixed direction of the rotation axis may be affected by movement of other mechanisms
Solution Approach 1:
The right-and-left changing mechanism is designed with a base member that pre-defines the fixed direction of the rotation axis before any movement occurs. This preliminary definition of the rotation axis direction ensures that subsequent movements of stacked mechanisms do not compromise the stability of the rotation axis, as the fixed direction is established by the rigid base member structure that serves as the reference frame for all other adjustments.

AI summary
A display system includes a display panel that displays information and a movement apparatus that moves the display panel. The movement apparatus includes: a slide mechanism configured to move the display panel linearly relative to a base chassis; a right-and-left tilt mechanism configured to change an angle of a display surface of the display panel in a right-and-left direction; an up-and-down tilt mechanism configured to change an angle of the display surface of the display panel in an up-and-down direction; and a rotation mechanism configured to rotate the display panel on a rotation axis orthogonal to the display surface of the display panel.
