Double-Walled HUD Shielding Frame for Vehicle Dashboards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs with head-up displays and ventilation systems face challenges in reducing installation space and enhancing dimensional stability, particularly in the vehicle longitudinal direction, while maintaining effective shielding and projection functionality.
Innovation Solution
A double-walled shielding frame with a torsion-resistant structure serves as both a light shield and a stiffening element, allowing for a compact arrangement of the head-up display and ventilation system, with angled support flanges for simplified assembly and increased rigidity, and an airtight connection to the dashboard for enhanced airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional shielding frame with single-wall structure is used, then the device complexity is reduced, but the dimensional stability and torsional rigidity deteriorate
Solution Approach 1:
The shielding frame is segmented into a double-wall structure with inner and outer walls, creating a torsion-resistant box section that significantly improves dimensional stability while maintaining manageable complexity through modular construction
Solution Approach 2:
The shielding frame employs a composite double-wall structure where inner and outer walls are connected by transverse connecting elements, creating a composite structural system that enhances torsional rigidity and dimensional stability
2Volume of moving object
If components are arranged with high packing density, then the installation space is reduced, but the manufacturing precision and assembly difficulty increase
Solution Approach 1:
The shielding frame merges multiple functions into a single integrated structure: light shielding, structural stiffening, and mounting support through integrated support flanges, reducing the need for separate components and simplifying assembly
Solution Approach 2:
The double-wall shielding frame structure serves multiple purposes simultaneously: optical shielding, structural reinforcement, airflow channel formation, and mounting support, enabling compact arrangement without compromising precision
3Strength
If a double-walled shielding frame structure is used, then the dimensional stability and torsional resistance are improved, but the device complexity and manufacturing effort increase
Solution Approach 1:
The double-wall structure is segmented into modular sections with inner and outer walls connected by transverse elements, creating a torsion-resistant box section that improves strength while maintaining manageable complexity through standardized modular construction
Solution Approach 2:
The complex double-wall structure simultaneously provides light shielding, structural stiffening, airflow channel formation, and mounting support functions, justifying the increased complexity through multiple beneficial outcomes

AI summary
A vehicle with a front windshield and a dashboard, which has a ventilation device with a defroster air outlet, and which has a head-up display integrated into the dashboard and has a front windshield projector, and a shielding frame, which delimits a projection passage, through which the front windshield projector projects optical information onto the front windshield and/or onto a combiner screen disposed in the region of the front windshield. The shielding frame is formed closed in the form of a frame with a front frame part, facing the front windshield, and a rear frame part facing away therefrom, which are connected to one another via side frame parts. The front frame part of the shielding frame is made double-walled with an inner wall, delimiting the projection passage, and an outer wall facing the front windshield, which form the defroster air outlet therebetween.
