Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-vehicle display systems occupy significant space in vehicles, compromising user experience and safety by requiring multiple systems for different types of information display, with limited viewing angles and real-time data requirements.
Innovation Solution
An integrated on-vehicle display system incorporating a curved protection housing as a reflecting mirror, combined with an optical path redirecting component and lens assembly, to project images from a display device onto the driver's line of sight without occupying excessive space, allowing for adjustable viewing angles and distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate on-vehicle instrument system and head-up display system are used, then different information can be displayed according to their respective characteristics, but significant space in the vehicle is occupied
Solution Approach 1:
The patent merges the on-vehicle instrument system and head-up display system into a single integrated display system. The instrument panel serves dual functions: displaying traditional vehicle status information directly on its surface, and simultaneously acting as a reflective surface for head-up display information from a separate display device positioned above the instrument panel. This combination allows both systems to coexist in a unified structure, providing comprehensive information display capabilities while significantly reducing the space occupied compared to having two separate systems.
Solution Approach 2:
The instrument panel is designed with multi-functionality, serving both as a display surface for traditional vehicle information and as a reflective mirror for head-up display information. The display device positioned above the instrument panel can project information that reflects off the instrument panel surface into the driver's field of view. This universal design allows a single component to fulfill multiple display functions, eliminating the need for separate dedicated spaces for each system.
2Ease of operation
If traditional on-vehicle instrument system is used, then large angle of view can be provided, but real-time information display is limited
Solution Approach 1:
The patent applies local quality by assigning different display characteristics to different information types within the same system. Traditional vehicle status information displayed directly on the instrument panel uses a wide viewing angle design for easy visibility from various driver positions. Meanwhile, head-up display information projected above the instrument panel uses a more focused, direct-line-of-sight approach optimized for real-time critical information delivery. Each display zone has optimized properties suited to its specific function, allowing both wide viewing angle and real-time display capabilities to coexist.
3Reliability
If head-up display system is used, then real-time information can be displayed, but limited viewing range is available
Solution Approach 1:
The instrument panel serves as an intermediary element between the head-up display device and the driver's field of view. The display device projects information above the instrument panel, which then reflects off the instrument panel surface into the driver's eyes. This intermediary arrangement allows the head-up display information to reach the driver within the natural field of view while maintaining real-time display capabilities. The instrument panel acts as a reflective mediator that extends the effective viewing range without compromising real-time information delivery.
