Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up display systems are bulky and inflexible, occupying significant space after installation and unable to adjust to individual driver preferences or varying vehicle types.
Innovation Solution
A head-up display system with a split structure comprising a display screen, imaging lens, and a curved reflector, where the display screen and imaging lens are fixed relative to each other, and the curved reflector is adjustable, allowing for flexible positioning and angle adjustments to accommodate different drivers and vehicle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an existing head-up display system uses an integrated structure with fixed components, then the structural stability is improved, but the volume occupied increases and adjustability decreases
Solution Approach 1:
The optical system is divided into separate components: a fixed display screen, a fixed imaging lens, and an adjustable curved reflector. This segmentation allows the reflector to be independently positioned and angled to suit different drivers, while the fixed lens and screen maintain structural stability. The separated architecture reduces overall volume compared to integrated designs.
2Ease of manufacture
If an existing head-up display system uses a fixed integrated structure, then the manufacturing simplicity is improved, but the adaptability to different drivers and vehicle types decreases
Solution Approach 1:
The curved reflector is designed as a movable component that can be adjusted in position and angle, transforming the static optical system into a dynamic one. This allows the same display system to adapt to different driver preferences and vehicle types without requiring custom manufacturing for each configuration, maintaining manufacturing simplicity while enhancing adaptability.
3Adaptability or versatility
If the curved reflector is made adjustable in position and angle, then the adaptability to different drivers is improved, but the device complexity increases
Solution Approach 1:
The adjustable curved reflector is designed as a standalone component separated from the fixed display screen and imaging lens. This segmentation isolates the complexity of adjustment mechanisms to only the reflector portion, while the core optical components remain simple and fixed. The modular approach allows adaptability without proportionally increasing overall device complexity.

Implementation Method 1
an imaging lens arranged on a light emitting side of the display screen and used for imaging an image displayed on the display screen
Implementation Method 2
a curved reflector arranged on a side of the imaging lens facing away from the display screen and used for receiving imaging light from the imaging lens and reflecting the light to positions of human eyes

AI summary
A head up display system, including: a display screen used for displaying an image; an imaging lens arranged on a light exit side of the display screen and used for imaging an image displayed on the display screen; and a curved reflecting mirror arranged on the side of the imaging lens facing away from the display screen and used for receiving imaging light of the imaging lens and reflecting said light to the position where human eyes are located. Relative positions of the display screen and the imaging lens are fixed, and the imaging lens and the curved reflecting mirror adopt a separate structure.
