Head-Up Display Mounting for Vehicle Cockpit Image Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cockpit designs with head-up displays are complex to install and maintain, particularly in modular designs, as they require disassembly of the instrument panel for repairs and are sensitive to vibrations, which affects image readability.
Innovation Solution
A vehicle cockpit with pre-installation attachment means on the transverse beam for the head-up display, allowing for modular assembly outside the vehicle, followed by secure attachment to a supporting body part, ensuring minimal relative movement and easy servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the head-up display is attached directly to the end wall or lower windshield frame, then the image stability is improved, but the installation complexity and repair difficulty increase
Solution Approach 1:
The mounting system is divided into multiple segments: a first mounting structure attached to the end wall, a second mounting structure attached to the head-up display, and a connecting element joining them. This segmentation allows the head-up display to be mounted independently before final assembly, reducing installation complexity while maintaining image stability through the rigid connection path.
2Ease of operation
If the head-up display is installed before the transverse beam, then the installation accessibility is improved, but the modular design compatibility deteriorates
Solution Approach 1:
The head-up display is pre-mounted on the transverse beam assembly outside the vehicle before final installation. The mounting structures are prepared in advance, allowing the entire assembly to be installed as a module, which maintains both accessibility and modular design compatibility.
3Ease of repair
If the instrument panel is dismantled for head-up display repair, then the repair accessibility is improved, but the repair time and complexity increase
Solution Approach 1:
The mounting system is segmented to allow the head-up display to be detached from the mounting structures without dismantling the entire instrument panel. The connecting element can be removed independently, enabling quick repair access while maintaining panel integrity.
4Adaptability or versatility
If the head-up display is mounted with long connection paths, then the installation flexibility is improved, but the image stability during vibration deteriorates
Solution Approach 1:
The mounting system uses rigid mounting structures and a stiff connecting element to create a short, rigid connection path between the end wall and the head-up display. This local rigidity minimizes relative movements and maintains image stability during vehicle vibrations, while the overall design still allows installation flexibility.

AI summary
A vehicle cockpit includes a head-up display, a transverse beam, and an end wall for separating the cockpit from the engine compartment. To fit the head-up display in a relatively easy manner, a holder is provided for pre-fitting or pre-installing the head-up display on the transverse beam and for a final fitting of the head-up display on a further supporting body part. As a result, the transverse beam with the pre-fitted head-up display can be inserted in the vehicle as a module.
