Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large vehicle displays in commercial or industrial vehicles face instability due to reduced viewing angles, weight, and vibrations, which can lead to damage and discomfort for the driver from oscillations.
Innovation Solution
A support device with a hinge and sled sliding system that connects the display to the dashboard, providing three-point support with vibration damping, ensuring stability and adjustability for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display is made larger to provide better information and entertainment, then the viewing quality is improved, but the display becomes heavier and more prone to vibration damage
Solution Approach 1:
The support device is divided into two independent support points: a hinge connection at the first side of the display and a sled sliding system at the second side. This segmentation distributes the load and provides balanced support for large displays, preventing overload on a single support point while maintaining stability during vehicle movements.
Solution Approach 2:
The sled sliding system introduces a sliding dimension along the longitudinal axis of the vehicle, allowing the display to move in multiple directions (rotation via hinge + sliding via sled). This multi-dimensional support approach enhances stability and strength distribution across the display structure.
2Ease of operation
If the display is made adjustable to improve viewing angle, then the usability is improved, but the support becomes more fragile
Solution Approach 1:
The display support system incorporates dynamic adjustability through the hinge mechanism that allows rotation between fixed and adjustable positions. This dynamic capability enables the display to adapt to different viewing preferences while the robust dual-support construction (hinge + sled) maintains reliability throughout the adjustment range.
3Device complexity
If the display is supported at one point to simplify the structure, then the device complexity is reduced, but the stability is insufficient
Solution Approach 1:
Instead of a single support point, the system segments the support into two distinct locations: the hinge at the first side and the sled sliding system at the second side. This segmentation creates a stable distributed support structure that prevents display oscillation while maintaining reasonable structural complexity.
Solution Approach 2:
Different support mechanisms are applied at different locations: the hinge provides rotational support at the first side while the sled sliding system provides linear sliding support at the second side. This localized optimization of support types enhances overall display stability.
4Ease of operation
If vibration damping means are added to reduce oscillations, then the driver comfort is improved, but the device complexity increases
Solution Approach 1:
Vibration damping functionality is merged into the existing hinge and sled sliding system components rather than adding separate damping devices. The hinge and sled structures incorporate damping characteristics that reduce oscillations during vehicle acceleration and braking, improving driver comfort without significantly increasing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the stability and strength of the display, reducing vibrations and oscillations, thus improving the comfort and reliability of the display system, especially during vehicle acceleration and braking.

AI summary
Support device of an adjustable vehicular display (M) integrated in a dashboard (D) of a vehicle, in particular an industrial or commercial vehicle having the display (M) integrated in the dashboard in a substantially central position. The support device comprises - a hinge (1) connecting the first side (Ma), near to the driver's seat, to the dashboard (D) and defining an axis of rotation (X) parallel to the first side (Ma), - a sled sliding system (2) connecting the side (Mb), opposite to said first side (Ma), to the dashboard (D) and suitable to limit a rotation of the display (M) around the hinge (1) and to cooperate with the hinge (1) in supporting the display (M).
