Solution Overview
Problem
Existing display devices in modern motor vehicles face challenges in efficiently utilizing installation space due to the need for flexible display elements that can be hidden or deployed based on size requirements, while maintaining mechanical support and flexibility during manual operations.
Innovation Solution
A display device incorporating a flexible carrier element with a honeycomb structure and integrated carrier bars that allows rolling-up and provides sufficient stiffness, featuring a support structure with cells forming a honeycomb design and recessed assembly regions for components, ensuring flexibility and mechanical support during touch operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a flexible carrier element is used to enable rolling-up of the display film, then the display device can be compactly stored and space utilization is improved, but the mechanical support and stiffness during manual touch operation deteriorate
Solution Approach 1:
The carrier element is segmented into a flexible base layer and a separate support structure with cells, allowing the system to provide mechanical support only where needed while maintaining flexibility in other areas. The support structure consists of multiple cell units that can be distributed across the carrier element surface.
Solution Approach 2:
The support structure provides localized stiffness through cells with specific geometric configurations, while the carrier element maintains flexibility in regions without cells. This allows different parts of the carrier element to have different mechanical properties - stiff where support is needed, flexible where rolling-up is required.
2Adaptability or versatility
If the carrier element is made flexible to enable rolling-up, then adaptability and space efficiency are improved, but the ability to withstand operating forces during touch operation deteriorates
Solution Approach 1:
The force resistance function is segmented and distributed across multiple cell structures rather than requiring the entire carrier element to be rigid. Each cell acts as an independent force-dissipating unit, collectively providing sufficient support for touch operations while allowing the overall structure to remain flexible.
Solution Approach 2:
The carrier element combines a flexible base material with a support structure made of different material properties. This composite construction allows the flexible substrate to enable rolling-up while the support structure material provides the necessary force resistance for touch operations.

AI summary
A display device to display content, comprising a display film to display the content; and a flexible carrier element including a rear side which bears the display film; and a rolling mechanism to allow at least a part of the display film and at least a part of the flexible carrier element to roll about a rolling-up axis so as to form a roll shape. The flexible carrier element is configured as a carrier film on which is configured a support structure that projects perpendicular from the carrier film and extends on a side of the carrier film facing away from the display film. The support structure has a plurality of cells open on one side and delimited on an opposite side by a cell base with cell sides delimited by cell walls projecting perpendicular where a cell wall is shared in pairs to thereby form a honeycomb structure.
