Integrated Head-Up Display and Cluster with Rotating Combiner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up display and cluster systems in vehicles independently installed, leading to a blocked driver's field of vision and poor space utilization due to the distribution of necessary information across two separate products.
Innovation Solution
Integration of a display unit and a combiner unit within a cluster housing unit, where light from the cluster housing unit is irradiated onto a combiner unit to form images, allowing for expanded driver vision and enhanced space utilization, with regions for displaying vehicle speed, engine RPM, fuel condition, vehicle status, fault information, advanced driver assistance systems, and audio/video navigation information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If necessary information is distributed to two separate products (head-up display and cluster), then information can be displayed in multiple locations, but the driver's field of vision is blocked and space utilization is poor
Solution Approach 1:
The patent combines the head-up display unit and cluster into a single integrated assembly. The display unit is positioned above the cluster housing, and the combiner unit is integrated within the same structure, allowing both information display functions to be consolidated in one location rather than distributed across separate products, thereby reducing visual obstruction while maintaining comprehensive information coverage
2Reliability
If head-up display and cluster are independently installed, then each unit can function autonomously, but the structure becomes complicated and space utilization is poor
Solution Approach 1:
The patent integrates the head-up display unit and cluster into a single assembly structure. The display unit is mounted above the cluster housing, sharing common mounting structures and housing, which simplifies the overall installation structure while maintaining the autonomous functional capabilities of both units through separate optical and electronic pathways
3Device complexity
If display unit and combiner unit are integrated with each other, then space utilization is enhanced and structure is simplified, but the complexity of light path design increases
Solution Approach 1:
The patent divides the integrated display system into distinct functional modules: the display unit with its own light source and optical path, the combiner unit with separate reflective surfaces, and the cluster housing. This segmentation allows for modular assembly and simplifies light path design by treating each module as an independent unit with defined optical interfaces, reducing the overall design complexity despite the integrated structure

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated system enhances driver visibility by consolidating information display, improving space utilization and simplifying the structure, allowing drivers to maintain focus on the road while accessing essential vehicle information without obstructing their view.
Implementation Method 1
a combiner unit rotatably coupled to the cover unit, light generated in the cluster housing unit being irradiated onto the combiner unit to form an image
