Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up displays (HUDs) require multiple units to project multiple images, which is inefficient and costly.
Innovation Solution
A display device incorporating a switchable optical component that can alternate between reflection and transmission states, allowing a single unit to project multiple images by controlling the optical component's state in synchronization with the display panel's output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple HUDs are provided to project multiple images, then the number of projected images increases, but the device complexity and cost increase
Solution Approach 1:
A single HUD system is designed to perform multiple functions by projecting different images to different sites through a switchable optical component. The optical component can be switched between reflecting light to a first site or transmitting light to a second site, enabling one HUD to replace multiple HUDs and achieve multi-functionality.
Solution Approach 2:
The optical component is made switchable between reflection and transmission states, allowing dynamic control of light paths. This dynamic switching capability enables the system to adaptively direct light to different projection sites based on the desired image output, resolving the contradiction between projecting multiple images and maintaining simple device structure.
2Adaptability or versatility
If a switchable optical component is added to enable multiple image projection, then the versatility improves, but the device complexity increases
Solution Approach 1:
The switchable optical component serves multiple purposes: it can reflect light to the first site, transmit light to the second site, and be integrated into a single HUD system that replaces multiple HUDs. This multi-functional design enhances versatility while avoiding the need for separate systems for each function.
Solution Approach 2:
The patent combines the functions of multiple HUDs into a single integrated system by merging the optical paths through a switchable optical component. This consolidation allows one HUD to perform the work of multiple HUDs, improving versatility without proportionally increasing device complexity.
