Combiner Head-Up Display Adjustable Holder Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing a head-up display (HUD) system that can be easily integrated into various vehicle windshields of different shapes and sizes, while minimizing driver distraction and allowing for adjustable positioning to accommodate different driver viewpoints.
Innovation Solution
A combiner HUD system featuring a combiner mirror and holder with adjustable knobs and mechanisms for positioning, allowing the mirror to be moved between stowed and display positions, and fine-tuned for optimal viewing angles, independent of windshield shape and size, using a combiner mirror with a transparent plastic disc and adjustable knobs with knurled surfaces for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the HUD projects an image onto the windshield, then the driver can view information without looking away, but it becomes difficult to design a HUD that works with all windshield shapes and sizes
Solution Approach 1:
The patent employs adjustable holder arms with knobs that allow the combiner mirror to be dynamically repositioned to different angles and locations. This dynamic adjustability enables the HUD to adapt to various windshield geometries without requiring multiple fixed designs, resolving the contradiction between versatility and design complexity.
Solution Approach 2:
The system allows changing the positional parameters (location and angle) of the combiner mirror through the adjustable holder mechanism. By varying these parameters, the same HUD device can be configured to work with different windshield shapes and sizes, achieving adaptability without increasing fundamental design complexity.
2Adaptability or versatility
If the combiner mirror is fixed in position, then the structure is simple, but it cannot accommodate different driver viewpoints or windshield configurations
Solution Approach 1:
The holder arms are designed with adjustable mechanisms including knobs and links that enable the combiner mirror to be repositioned. This dynamic capability allows accommodation of different driver viewpoints and windshield configurations while maintaining a relatively simple overall structure through modular adjustment components.
Solution Approach 2:
The positioning system is segmented into multiple independent adjustment mechanisms (first holder arm for location, second holder arm for angle, with separate knobs for each). This segmentation allows each degree of freedom to be adjusted independently, providing versatility without requiring a completely complex integrated system.
3Ease of manufacture
If the HUD is designed for a specific vehicle configuration, then the design is simpler, but it cannot be easily integrated into vehicles with different windshield designs
Solution Approach 1:
The combiner holder assembly is designed as a universal mounting mechanism that can be configured for different windshield geometries. The adjustable holder arms and positioning knobs provide multi-functionality, allowing the same basic design to be integrated into various vehicle models without requiring model-specific customization, thus improving ease of manufacture while maintaining adaptability.

Function Achieved in This Case
Enables flexible installation and adjustment of the HUD system in vehicles with diverse windshield configurations, reducing driver distraction by providing a clear, adjustable display that maintains the driver's forward view, regardless of vehicle design or windshield shape.

AI summary
A combiner head-up display (HUD) system includes a combiner mirror and a combiner holder supporting the combiner mirror. The combiner holder includes first and second holder arms. The HUD system also includes a combiner HUD body supporting a first knob. The combiner HUD system includes an elevation link connecting the first knob and the first holder arm. A rotation of the first knob causes the combiner mirror to move from a stowed position to a display position or from a display position to a stowed position. A second knob is supported by the combiner HUD body and is disposed substantially opposite the first knob. A threaded rod connects the second knob and the second holder arm. When the combiner mirror is in the display position, a rotation of the second knob causes the combiner mirror to adjust a display angle between the fore-aft axis and the combiner mirror.
