Folding Mirror Rotation Mechanism for Head-Up Display Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up display systems do not easily adapt the position of light rays to accommodate users of different sizes, making it difficult for drivers to effectively view virtual images without looking away from the road.
Innovation Solution
The rotation means for the folding mirror is located at the edge region opposite the partially transparent blade, allowing for easy adjustment of light ray position and concealment within a casing, enabling precise adaptation to any user's needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotation means are located in a conventional position for adjusting light ray position, then adaptability to different users is improved, but device complexity and space requirements increase
Solution Approach 1:
The rotation means are positioned at the edge region of the support, utilizing the lateral dimension rather than conventional longitudinal positioning. This dimensional repositioning allows the rotation mechanism to be integrated into the edge structure, reducing overall device complexity while maintaining full rotational functionality for adapting light ray positions to different user eye levels.
2Ease of manufacture
If rotation means are positioned to be concealed within casing, then ease of manufacture and aesthetics are improved, but accessibility for adjustment may be reduced
Solution Approach 1:
The edge region of the support acts as an intermediary zone between the internal optical components and the external environment. By positioning rotation means at this edge region, the mechanism can be partially concealed within the casing for manufacturing simplicity and aesthetic purposes, while still providing sufficient accessibility for users to perform adjustments without requiring complete exposure of the internal mechanisms.
