Offset Rib Carrier Plate for Display Device Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface supporting structures for display devices in vehicles face challenges in balancing stability, weight reduction, air ventilation, and efficient force transmission while maintaining structural integrity under vibrations and thermal stress.
Innovation Solution
A carrier plate with integrally formed ribs on both sides, offset in a specific direction, and continuous recesses to reduce mass, combined with adaptable rib heights and angles, and a receiving device for fasteners, which allows for enhanced flexural stability and air ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If ribs are arranged opposite each other or omitted, then the carrier structure is simpler, but the flexural stability in the longitudinal direction is reduced
Solution Approach 1:
The patent applies asymmetry by arranging ribs on opposite sides of the carrier plate in offset positions rather than directly opposite each other. The ribs are positioned at different longitudinal locations on the front and rear sides, creating an asymmetric pattern that enhances flexural stability while reducing structural complexity compared to traditional opposite arrangements.
2Strength
If the carrier is made solid without ribs, then the structural integrity is higher, but the mass is significantly increased
Solution Approach 1:
The patent applies segmentation by dividing the solid carrier plate into a ribbed structure. Instead of using a completely solid plate, ribs are strategically positioned to provide structural support while leaving spaces between them. This segmented approach maintains structural integrity through the rib framework while significantly reducing the overall mass compared to a solid construction.
3Weight of stationary object
If continuous recesses are made in the carrier plate, then the mass is reduced, but the structural stability may be adversely affected
Solution Approach 1:
The patent applies local quality by making recesses in specific local areas of the carrier plate rather than uniformly throughout. The recesses are positioned in regions where they reduce mass while minimizing impact on structural stability. This localized modification allows weight reduction while preserving the overall structural integrity provided by the rib arrangement.

AI summary
The invention relates to a carrier, in particular for a display device, with a carrier plate (31), wherein the carrier plate (31) has two opposite flat sides (32, 33), wherein a plurality of ribs (34, 36, 38, 39) are integrally formed on each of both sides (32, 33), wherein the ribs (34, 36, 38, 39) on both sides (32, 33) are each oriented parallel to one another, wherein the ribs (34, 36, 38, 39) on both sides (32, 33) are oriented in the same, first direction (35) and wherein the ribs (34, 36) on a first side (32) are arranged offset, in a second direction (37) perpendicular to the first direction (35), with respect to the ribs (36, 38) on the second side (33) opposite the first side (32) in such a way that the ribs on the first (32) and on the second (33) side are not or not fully cross-sectionally opposite one another.
